Abstract: 5956. Ellis, W. E. March 16, 1912, [Convention date]. Bows.-Relates to machines for making bows, for slippers &c., and more particularly to a machine for making bows of the type described in Specification 19,225/12, which consists of a body portion made from a strip of ribbon &c. having its ends folded under its central portion, and if desired having a lining or stiffening piece, an attaching strip, usually of buckram, applied to the underside of the body portion, and a central band crossing the outer side of the body portion and having its ends folded under the attaching strip, the whole being secured together by a pronged metal plate &c. The anvil 7, on which the parts of the bow are assembled and secured, is carried by the head 6 pivoted at 5 on the frame, and is normally held in raised position, as shown in Fig. 2, by a spring 19 &c. Secured beneath the anvil is a forwardly-extending metal strip 22, forming with the anvil a recess 23. The central band of the bow is placed in the recess 23 with its edge against the gauges 45, 46, and the body portion of the bow and the attaching strip are placed, with the latter uppermost, on the anvil, and adjusted against the end-stop 8 carried by the head 6, where they are held by the spring clip 8<a>. The anvil is then depressed until it rests in the recess 3 of the table, after which the disk 9 is rotated by its handle 10, so that the cam slots 11, 12 on the disk, acting on the studs 13, 14 fixed to the sliding plates 15, 16, force these plates towards each other, and cause the jaws 17, 18 thereon to fold the central band over the bow and retain it in that position; the jaws also overlie the anvil and prevent it from rising until they have been retracted. A pronged metal plate or clip 36, Fig. 2, having been placed in the clamping hammer 30, the hammer is caused to descend by the action of a treadle, and so forces the prongs of the plate 36 through the folded ends of the central band and the body of the bow, until they are clenched upon the anvil, which is formed with grooves 47 to facilitate the clenching action. The head 26 of the hammer 30 is provided with two vertically-sliding spring-controlled plungers 31, which have shallow recesses on their inner sides to engage the edges of the plate 36 and hold it until it is driven. A stop-plate 35 is also provided, to facilitate positioning of the plate. In a modified form of hammer, for use with narrower plates, the plungers 31 are carried directly by the hammer, and are set closer together. In the further modification shown in Fig. 8, for use with a two-pronged clip or staple, the staple 52 is held, until driven, within the prongs 51 of a spring-controlled carrier 48 slidably mounted on the hammer 50. To adapt the machine for making bows of different shapes and sizes, the anvil and folding jaws &c. are made detachable, so that they can be interchanged for others, and the gauges 45, 46, stop 8, and the plates 15, 16 are made adjustable in position.
