Letters Patent lVo. 80,491, dated July 28, 1868.
l IMPROVEMENT IN HEAD-BLOCKS POB. SAW-MILLS.
@La .tlntrle referat tu in tigen tetta tant mit matingpart if tige same. wmwwmm y j TO ALL PERSONS TO WHOM THESE PRESENTS SHALL COME:
Be it known that I, DENNIS LANE, of Montpelier, in the county of Washington, and State of Vermont, have invented certain new and useful Improvements in Saw-Mill Carriagesg and that the following description, taken in connection with the accompanying plate of drawings, hereinafter referred'to, forms a full and exact specification of the same, whereby my invention may be distinguished from all others of a similar class, together with such 'parts as I claim and desire to have secured to me by Letters Patent.
The present invention relates to saw-mill carriages, in`which the' slide or bar carrying the uprightsupports is moved across and upon the head-blocks by the action of inlines fixed to a rack-bar that is susceptible of being run along across' the head-blocks'in the direction of the length of the carriage; and the invention consists-f -v First, in parallel inclines, attached to the said traversing rack-bar, in combination with projecting pieces or grooved ways, located within the head-blocks, and peculiarly arranged and combined therein, whereby, as the said inclines, by and through their rack-bar, are moved either forward or backward in the direction of the length of the carriage across the head-blocks, they will, at the same time, move inea direction along the length of the same, either forward or backward, as the casc'may be, and thus, byfconfning the slide-bar to such inclines, carry such barin a corresponding direction, that is, either forward' or backward, as theY case may be,
upon the head-blocks. i
Second, in a' peculiar-formed and constructed strap, for confining tne travelling rack-baran'd inclines to the slide-bar, whereby rigidity and' firmness of motion are obtained, and a firm bearing for the log secured.
Third, in so hinging or swivelling the handle, by means of which the inclins are operated to feed `the slide-bar forward to the saw, that it can be adjusted in positibn for being used either upon the front or rear side of the carriage or saw-mill, and to enable power to be applied to the handle in thefmost-eifective and convenient manner for the operator. .v
And the invention consists in further improvements in the details of'the saw-milhwhich improvementswill be hereinafter more particularly referred to, whereby many important advantages are secured. `i
In the accompanying plate of drawings-my. improvements in saw-mill carriages Aare illustrated- Figure l being a plan or top view offthecarriage with my improvements applied, and
Figure 2 a transverse vertical section taken in the plane ofthe line :n x, fig. 1. s
A, in the drawings, represents the-carriage to a saw-mill, which carriage may bc of any of the usual forms and constructions. v i u B, head-blocks fixed upon carriage A, across from one side-bar or rail to the other.
C, the slide-bar, having upright supports D secured to it at suitablepoints, these supports formingbearings against which the log being sawed rests. This slide-bar C has plates E secured to its Vunder side, which4 plates have `parallel lips or flanges F, of suitable shape, in transverse section, to t and run in grooves made along the lside-faces ofthe head-blocks, from one end to the other, as the slide-bar is moved forward or backward thereon,
thus guiding and Vsteadying it in such motion. i
G, two frames joined together by a connecting-bar or rail, II. These frames-G, with their connecting-bar H, are` placed upon the head-blocks to the rear side ofl'the slide-bar C, and `to this bar they are confined by means, upon their front edges I, of theupright lips or flanges J, to theplates E, hcreinbefore referred to,and upon their back or rear edges, K, by means of the upright arms-or flanges L, to the portions, M, of the fianges F of said plates E, that are extended back of the slidesbar along the side of4 the head-blocks. Between these `ianges J and upright arms L, the said frames move andrun, when operated, as will be hereinbelow described.
Each of these frames G is provided with two incline-bars, N, that are fixed in planes parallel to cach other, extending from rear to front rail o f frame. rlhese bars N, by angcs O, project below and to the top, or nearly so, of the head-blocks, which dangesextendin planes corresponding to that of the inclines.
P P2, pieces or blocks arranged in -each of the head-blocks, of which blocks there are two to each headblock, corresponding to the number of inclines N. 'These pieces P I?2 project above the surface of the headblocks, and in each head-block one, P, which is the rear or hind one, is fixed, and the other, P2, by an extensionpiece, Q, fixed to a bent spring, R, by means of which it isl susceptible of being depressed, as the frame with the incliiies rides or passes over it, both blocks, P P2, however, being provided, in their 'projecting portions above the head-blocks, with a groove orway, S, oi' a similar inclination and direction tothat ofthe inclines.
With these grooves or ways of the projecting blocks P P2, the inclines of the frames GIG become engaged, when such frames are moved forward and backward across the head-blocks in the direction of the'length ofthe carriage, and thus, as such inelines move lthrough them, the one incline within the other, and then, after that, the other incline in the other, (they being relatively so situated that the inclines, the one after the other, will so take them,)rgive a `{"orward-and-backward motion to the said frames along the lengthof the head-block to the said frames, and, as the slide-bar C is confined to it, a corresponding motion thereto, the inner one ci" the projecting blocks or grooved ways,vby its arrangement through a spring, being depressed by the slide-bar, so that it can pass over the same, in its forward and backward movement For moving the inclines along the lengthiof the carriage, the connecting-bar or rail H is provided, along its edge, S, toward the slide-bar. C, with a toothed rack, T, with which engages a 'pinion-wheel, U, at the lower end o f an upright'shaft, V, turning inA bearings oi' the upright post or standard W of the slide-bar C, so that, by the turning of the said shaft, the said barH, with the inclines, will be moved forward orbackward upon the carriage, as the case may be.
For operating the incline frames in 'the direction that would throw or move the slide-bar forward toward fthe saw, an arrangement of operating and holding-pawls X Y, respectively, lis provided for` operation upon the ratchet-wheel Z, attached to the vertical shaft V, but, as this arrangement of mechanism forms no part of the present invention, I do' not deenrit necessary to herein more particularly describe it. o
,'.lo move the inclines'ina direction to carry the slide-bar back, a gear-wheel, A2, is'iixed to the vertical shaft V, withi'nthe post or upright, which post, for the purpose of receiving thevsame, is made hollow. With this gear-wheel A2, a pinion-wheel, B2, of a horizontal shaft, Cho-f the side of the post is arrangedto engage, the said shaft C2 being provided with a handle, by which it can be turned. This shaft()2 is hung by a sleeve or collar E2, eccentric. therewith within the ost, yso that, b turninv such collar, with its handle F2 in the r a P .Y a i post, the pinion-wheel B2 can be thrown into or out of connection with the main gear A2 of the vertical shaft. The operating-parvis X, hereinbefore referred to, are carried by an arm, F4, that, for being operated, has at its outer ond a handle-lever, G2. 'lhis handle-lever G2 is hinged to a block, H2, swivelled inthe arm F", whereby it not only admits of being swung around, for being used either` upon the front or rear side of the carriage, as may be desired, but also allows the' handle to have a swinging motion'upon the arm F4, to which it is hung, as such arm moves toward the operator, the vconvenience and effectiveness of which to the operator is obvious. I
I '.lhe post W consists of two parallel-side uprights, H4, connected at Itheir upper end by a plate or disk,'12,
"over which the operating parts for the vertical shaft are arranged, and at their lower ends by a pla-te, J2, that is a part of the same, which-plate is fastened to the top of the slide-bar.
By this construction of the post W, while room is afforded for the gear-wheel A, the sides of the post are braced and stiienerhtosecure the requisite firmness to the said post for the action of the operating parts carried by t v l Having thus described my improvements', Iv shall state my claims, as follows:
What I claim as my invention, and desire to have secured to me by Letters Patent, is-
v1. The grooved `block P and the yielding grooved block P3, arranged in line in the same head-block, and I successively acted upon by each of the incline-bars N, arranged parallel in the reciprocating frame Gr, whereby the head-block is made to advance or recede,'as desired, all constructed and operating substantially asilescribed,
2. The sleeve E2, formingan eccentric bushing in the post W for the pinion-wheel B2, by which the pinion. wheel B2' is thrown in or out of gear with the bevel-wheel A, for the purpose of advancing or retractinglthe. carriage, constructed and operating substantially as described.
