BRAIDING-MACHINE.

Specificationof Letters Patent.

Patented Nov. 19, 1918.

Application filed December 8, 1916. Serial No. 135,825.

To all whom it may concern:

Be it known that I, EARL F. STANTON, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Braiding-Machines, of which the following is a specification.

My invention relates to braiding machines and its essential objects are to protect the operator from injury to hair, hands or clothing by reason of exposed gearing; to prevent the breaking of threads by entanglement with the mechanism; to muffle the noise of the operating parts; to furnish an oil bath for the gears whereby their 1on gevity is insuredtto afford compactness of structure whereby space is conserved in both thickness and diameter; to minimize the number of parts; to avoid the loosening and consequent tilting and cramping of the quoits; and to attain these ends in a simple structure, and by an inexpensive method or process of construction, and by a method which insures accuracy of registration in the assembly of parts.

To the above ends essentially my invention consists in such parts and in such combinations of parts, and in such steps, and successions of steps as fall within the scope of the appended claims.

In the accompanying drawings which form a part of this specification,

Figure 1 is a plan view of the body of a braiding machine, showing a portion of the top plate broken away to more clearly show the inclosed parts,

Like reference characters indicate like parts throughout the views.

My improvements relate only to the body or driving portions of a braiding machine, and for this reason the thread feeding and supporting portions are omitted from the showing.

In constructing the portion of the machine to which my invention appert'ains, a base plate 6 is cast with a central opening 7, having an upwardly directed peripheral flange 8, and a similar flange 9 around the central opening. An annularly arranged series of openings 10 in this plate, equidistant from the opening 7, are also bounded by tubular posts or cylindrical walls 11 cast integral with the base 6. At one portion of its periphery, the base is cast with a depressed or cup shaped extension 13 comprising a substantially circular base portion 14 and cylindrical wall or flange 15' continuous with the wall 8 and having its upper edge in the horizontal plane of the top edges of the walls 8 and 11. In the center of the base portion 14 is cast a bearing 16; and in the wall 15 is cast a bearing or sleeve 17. Vertical lugs 18, 19, 20, are preferably cast on the walls 8, 9, and 15 respectively; and holes 21, '22, and 23 for attaching screws are formed in the respective walls.

The top plate 24 is initially cast in a form corresponding to the contour of the bottom plate, comprising a circular body portion 25, and a curved extension 26, coinciding with the walls 8 and 15 of the base plate.

The plate 24 has its portion 25 cast with acircular series of openings 27 in vertical alinement with the centers of the tubes 11, and around each of these openings, upon the bottom face of the plate is a square or other angular projection or shoulder 29. These projections are adapted to fit in correspondingly shaped cavities or depressions 30 in the upper ends of the posts 11. The portion 26 of thetop plate has an opening 32 in vertical alinement with the bearing 16. Intersecting curved raceways 84 of the maypole type are cast in the top plate with each opening 27 concentric with a pair of loops. The portions 36 embraced by the pairs of loops, are initially connected to the remainder of the plate by the webs 37 bridging the raceways. These ebs are subsequently broken away with ease by a chisel, or other tool, and the edge of 'the'portion 36 is smoothed by grinding, thus constituting an interior carrier guide or quoit. The breaking of the webs forms the second or central section 38 of the top or guide plate adapted to coiiperate with the outer section 25.

The quoits are clamped by bolts or threaded pins 39 passing'thro'ugh the tubes 11 and the openings 10 and 27 and having nuts or heads 41 and 42 upon their ends abutting against the quoit and base plate respectively. J ournaled on each tube 11 is the hub 43 of a gear 44 provided with the usual radial ribs 45 upon its upper face to engage the base 46 of the spindles or carriers 47 which travel through the raceways.

The driving shaft 48, carrying upon its ends the pulle 49 and gear 50, is mounted in-the sleevel In'the bearing 1 6;is journaled the usual hand shaft 52 passing through the opening 32 and carrying the bevel gear 53 and the gear 54. The gear 53 meshes with the gear 50, and the gear 54 engages one of the gears 44, all of which are in mesh successively.

In assembling, the vertical lugs 18, 19, and register in marginal slots 56, 57, and 58 respectively in the guide plate portions and 26. Attaching screws 60 enter the threaded cavities 21, 22, and 23, through marginal perforations 61, 62, and 63 in the sections 25 and 38 of the guide plate, and

the portion 26 of the former respectively. Obviously, if desired, the portion 26 of the top plate may be cut or otherwise severed from. the main portion 24 of the guide plate, and form an independent removable plate. If desired, slotted attaching lugs 66, 67 and 68 may be cast upon the base 6 at selected points upon the periphery to admit screws for fixing the base upon a bench or other suitable standards.

The top and base plates constructed and assembled as described form a housing inclosing the annular chamber 69 and a chamber 70 containing the gearing and driving parts of the machine, not only protecting the mechanism and the operator, but forming inclosed receptacles that may be partially or wholly filled with oil 71 without danger of leaking, whereby the gears may run in the lubricant. The housing also muffies this sound. By this construction, the use of spacingstuds is avoided, thus avoiding expense and saving room. The present practice of fixing the interior carrier guides on the bearing stud which leads to their quick loosening and resultant cramping is avoided by the integral relation of the tubes 11 to the base 6, and the seating of the integral squared shoulders 29 in the sockets 30.

By casting the upper plate in the form shown,namely with webs 27, it is assured that-each quoit'36 will center relatively to the guide plates 25 and 38 to form uniform boundaries for the raceways without special grinding for that purpose.

I claim V i 1. In a braiding machine, the combination of a substantially annular base plate, vertical upturned walls integral with the base upon its inner and outer peripheries, tubular bearings integral with the base interme Copies of this patent may be obtained for diate the walls, a guide plate resting upon the walls, interior carrier guides upon the bearings, and gears upon the bearings intermeshingwith each other.

2.

3. In a braiding machine, the combination of a base plate, side walls upon the plate, a guide plate on the walls, tubular bearings integral with the base plate provided with angular cavities in their upper ends, interior carrier guides on the tops of the bearings provided with angular shoulders registering in the cavities, and with perforations in alinement with the bearings, bolts extending through the perforations and the bearings, and nuts on the bolts engaging the interior carrier guides and the base.

In a braiding machine, the combination of a base plate comprising an annular portion and a depressed curved extended portion, a vertical wall integral with the outer periphery of the annular portion of the base and the periphery of the extended portion, a lateral bearing in the extended portion of the wall, a vertical wall integral with the inner periphery of the base, said walls and base forming an annular chamber and an extension chamber opening into each other, a series of tubular bearings integral with the annular portion of the base, a guide plate mounted on the peripheral walls, interior carrier guides fixed to the tops of the bearings, carrier gears journaled on the bearings in the annular chamber, a driving shaft in the lateral bearing, and driving gears in the extension chamber connecting the main shaft with one of the carrier gears. 1

5. In a braidingmachine, the combination of a substantially annular base plate, vertical walls upon the inner and outer peripheries of the plate, and tubular bearings upon the base intermediate the walls, whereby a lubricant is retained around the bearings.

In testimony whereof I have aflixed my signature in presence of two witnesses.
