MACHINE FOR- FORMING WIRE GARMENT-STAYS.
SPECIFICATION forming part of Letters Patent No. 761,640, dated June 7, 1904. Application filed July 20, 1903. Serial No. 166,261. (No model.)
To all whom it may concern:
. Be it known that I, GEORGE Gr. ANNABLE, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga, in the State. of New York, have invented new and useful Improvements in Machines for Forming Wire Garment-Stays, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.
The purpose of this invention is to expeditiously and accurately bend wire into-serpentine shape, so as to produce therefrom a spring-band suitable for various purposes, chiefly for garment-stays; and for this purpose the invention consists in the novel organization of the machine hereinafter described, and set forth in the claims.
In the annexed drawings, Figure 1 is a side view of a machine embodying my invention. Fig. 2 is a top plan view of the same. Fig. 3 is a vertical section on line X X in Fig. 1. Fig. 4. is a detached side view of one of the wire-feeding bars and its actuating-cams. Fig. 5 is a detached side view of one of the plates attached to the feed-bar. Figs. 6, 7,
- and 8 are enlarged detail bottom plan, edge,
and end views of one of the, wire-bending plates; and Fig. 9 is a plan view of a portion of the manufactured spring-band.
In the said drawings, A represents the stationary supporting-frame of the machine,
which frame consists chiefly of two vertical walls disposed parallel side by side and at a sufficient distance apart to contain between them the main parts of the mechanisms of the machine. i
- Through the upper part of the frame A extend longitudinally two feed-bars 1 1, which are pivoted to the said frame, as shown at 2, in a suitable manner to allow said bars to oscillate vertically and .reciprocate to a limited degree longitudinally. These motions are derived from the following mechanisms arranged to operate said feed-bars alternately and in opposite directions from each other. Transversely through the. rear portion of the frame A extends the driving-shaft C, to which are fastened two sets of cams, one set for each feed-bar. of two cams 3 and 1, projecting in opposite directions from the shaft and engaging alternately two shoulders and 6, formed on a pair of plates 1, extending downward. from one of the feed-bars 1. one forward and the other rearward of the shaft, so that the engagement of the said cams produces the verticaloscillatory motions of the feed-bar. The same set also comprises a cam 7, fastened to the driving-shaftC and dis- 6o posed to engage a roller 8, pivoted to one of the plates 1 in front of the shaft C, and by this engagement the feed-bar 1 receives a forward motion. A suitable spring 9, connected at one end to the frame A and at the 65 opposite end to the feed-bar, serves to retract said feed-bar after it is released from the cam 7 Thefeed-bar is thus reciprocated longitudinally. The rearward thrust of the feed-bar is limited by an adjustable stop 9. 7
The top of the front end of each feed-bar is provided with rigid upwardly-projecting pins 10 and 11, which are preferably tapered to prevent their catching on the under side of the wire during the process of bending the 75 wire, as hereinafter described. Over the two feed-bars is a presser-bar 10, pivoted at one end to the frameAand disposed at the opposite end to receive under it the wire operated Lengthwise over said 80 on by the machine. presser-bar is a spring-plate 11*, attached at its front end to said bar and having its rear end rising therefrom and .passing under a cross-bar 12, attached to the frame A. A
screw 13,passing vertically through said cross- 3 5 bar and bearing on the free end of the springplate,alfords adjustment of the pressure thereof on the presser-bar.
Directly over the front ends of the two feed-bars 1 1 are two wire-bending fingers 14. 9 and 15, located at opposite sides of the two feed-bars and attached to vertical shafts 16,
suitably journaled in bearings on the frame A, and having its lower end shaped conical and stepped in a correspondingly-shaped socket in 9 5 the end of a post secured to the frame. The
shafts 16 are oscillated in reverse order'tooause the fingers 14. and to alternately swlng across Each of these sets consists The shoulders are disposed the tops of the feed-bars in front of the pins 10 and 11. The oscillatorymotion of each shaft 16 is derived from a cam 17, attached to the driving-shaft C and imparting longitudinal motion in one direction to a bar 18, which is connected to an arm 19, projecting laterally from the shaft 16 and turning said shaft in one direction. The reverse movement of this shaft is produced by means of a spiral spring 20, which is attached at one end to a collar 21, loosely embracing the shaft and adjustably confined on the frame A. The opposite end of the spring is attached to the hub of an arm 22, fastened to the shaft 16. The said arm coming in contact with a stop 23 on the frame A serves to limit the movement of the shaft 16 after it is released from the force of the cam 17. The aforesaid adjustability of the collar 21 1 preferably obtain by forming said collar With indentations 22 in its periphery and connecting to the frame Aan adjustable set-screw 23, engaging one of the indentations after the collar has 21 been turned to impart the desired tension to the spring 20. The wire-bending portion of each finger 14C and 15 I preferably form of a separate hookshaped plate 14*, adjustably attached to the free end portion of the finger and terminated with a tongue 14?, which is curved to pass across the top of the feed-bar in front of the pins 10 and 11. The extremity of the tongue 14 is pointed and beveled downward, and adjacent to the pointed end is a depending rib 14, projecting from the rear edge of the tongue and formed with a longitudinal groove 14 for receiving and guiding the wire a to the pins 10 and 11 of the feed-bar.
In the operation of the described machine the operator first bends by hand the end portion of the wire into the shape of a loop 1 of the spring-band (shown in Fig. 9 of the drawings) and hooks said loop onto the front pin 10 of one of the feed-bars 1, so as to cause the end of the wire to rest on the pin 11 of said bar, which retains the wire in its position while the succeedingloop is being formed. In forming the succeeding loop the retracted bar is moved forward and momentarily depressed to carry its pins out of the path of the wire, while the oscillating finger adjacent to the advanced feed-bar pushes the wire around the outer side of the pin 10 on said bar and into engagement with the pin 11, which serves to retain the wire in position. This feedbar then suddenly recedes, while the previously-retracted feed-bar advances in the same manner as before stated and carries its pins 10 and 11 into position to allow the opposite oscillating finger to bend the wire on said pins. The rearward movement of the feedbar is effected very suddenly and immediately after the oscillating finger has performed its required function and just before the opposite feed-bar comes into position to permit the formation of the succeeding loop of the wire.
Said abrupt movement is due to the abrupt termination of the cam 7 releasing suddenly the roller 8 and allowing the spring 1) to quickly retract the feed-bar. The oscillating fingers receive sufiicicnt inward thrust to cause the succeeding loop to pass slightly under the preceding loop, the subsequent recoil of the wire causing the loops to adjust themselves so as to abut at their edges, as shown in Fig. 9 of the drawings.
To allow the wire-bending lingers to beadjusted to carry the wire properly around the pins of the feed-bars, as hereinbeforc stated, I attach the hook shaped plate 14 adjustably to the body of the finger, preferably by pivotally connecting said plate at or near the center of its length to the body, as shown at 24, and providing the heel portion of the plate with a segmental transverse slot 25, through which passes a screw 26, which clamps the said plate in its desired position on the body of the finger.
27 denotes a guide provided with a transverse slot through which the wire passes from a reeloracoil to the machine in which the said wire is bent into serpentine shape, as shown in Fig. 9 of the drawings.
28 indicates by dotted lines a duct l'or guiding the bent wire from the machine.
