TRANSFERRING DEVICE.

srEcIFIoA'rIoN forming part of Letters Patent No. 625,259, dated May 16, 1899. I Application filed February 18, 1899. Serial No. 705,995. (N0 model.

pertains to make and use the same.

In transfer devices for knitting-machines and appurtenances as generally constructed the points are liableto displacement by being bent to one side or the other and when broken cannot be replaced except at great cost and by a skilled workman. are greatly weakened at their juncture with the cup or base by reason of their mode of connection therewith.

It is the purpose of the present invention to facilitate the removal of the points from the cup or body, so that a broken or bent point can be quickly substituted by a new one by any person; to preserve the primal stiffness and strength of the points throughout their length, whereby ordinary strain tending to bend the points laterally is resisted, and to improve and simplify the general construction,whereby the usefulness, durability, and ease of substitution of disabled points are such as to enhance the value of this class of devices and render them more desirable and serviceable.

Other objects and advantages are contemplated and will appear in the course of the following description, reference being had to the accompanying drawings, in which Figure l is a perspective view of the transferrer. Fig. 2 is a detail section of a portion of the device, showing the relation of the parts. Fig. 3 is a detail view in perspective of the clamp, the parts being separated. Fig. 4 is a detail view in elevation of a portion of the body or ring, the clamp being removed and some of the points omitted. Fig. 5 is a detailview of one of the points.

Corresponding and like parts are referred to and indicated in all the views of the drawings by the same reference characters.

The body 1 of the transferrer is of annular Moreover, the points form, and its outer side slopes or inclines and is provided with regularly-spaced grooves or channels 2, extending at right angles to the plane of the top and bottom edges. The lower edges of the body or annulus are cutaway from the outer side, forming a shoulder 3 and pendent portion 4. The grooves 2 extend through the shoulder 3, and a marginal portion exists between the pendent part 4 and the ends of the grooves for the rim 5 of the lower clamp member 6 to bear against, thereby preventing the projecting ends of the points 7 from scraping or interfering with the free rotation of the member 6 when giving the final turn thereto to tighten the clamp.

The points 7 are of usual shape and are formed in the ordinary manner. The folded side portions stand apart throughout their length,and the parts thereof corresponding to the shank or the portion fittedinto the grooves of the body are compressed. when the points are seated in the said grooves. The tendency of the compressed shank portions to spring outward creates a frictional engagement bebetween the Walls of the grooves and the compressed portions of the points of such degree as to retain the points in place when properly applied to the ring. Moreover, the points are not weakened, as is the case where the shank portions arepressed together, forming a shank to enter a saw cut or kerf of the body or cup.

The clamp is of ring form and consists of two members 5 and 8, having screw-thread connection. The band 8 flares slightly to conform to the taper of the body or ring and is of such internal diametrical extent as to fit upon the upper portion of the body, with its lower edge a short distance from the shouldered end 3. beveled upwardly to the plane of the body and points, whereby a neat and light structure is obtained. The ring 6 is milled to enable a grip to be secured when rotating it to tighten or loosen the clamp. The vertical portion 9 of the ring is screw-threaded to match the corresponding threads-of the band 8, and the horizontal portion 10 has the rim 5 at its inner edge, which prevents contact of the part 10 with any projecting ends of the points. The inner diameter of the part 10 is coexten- The outer side of the band 8 is sive with the outer diameter of the part 4, so as to receive the latter, thereby centralizing the member 5.

In the event of a point 7 becoming broken or otherwise unfitted for service it can be detached by loosening and removing the clamp and a new one placed in position. No tools or skilled help are required to effect the result.

In adapting the invention to the various forms and styles of transfer devices it is to be understood that changes in the form, proportion, and minor details ofconstruction may be resorted to without departing from the nature of the invention.

Having thus described the invention, what make screw-thread connection with the said band, substantially as specified.

2. In a transfer device, a circular body havin g its outer side grooved and made tapering, and having its lower edge shouldered and formed with a pendent portion ,transfer-points seated in the grooves of the body, a band encircling the body, and a ring having a horizontal portion to engage with the shouldered end of the body and formed at its inner edge witha rim to bear against the inner marginal portion of the shoulder, and having a vertical portion to make screw-thread connection with the aforesaid band, substantially as and for the purpose set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
