JEFFERSON M. OLOUGH, OF ILION, NEW YORK.
Specification forming part of Letters Patent No. 122,307, dated January 2, 1872.
' Be it known that I, JEFFERSON M. GLoUGH, of Ilion, in the county of Herkimer and State of New York, have invented certain new and useful Improvements on Machinery for Punching and Swaging Cotton-Gin Saw-Teeth; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing making part of this specification, in which Figure 1, Plate 1, is an elevation of one side of the improved machine. Fig. 2, Plate 2, is a section taken vertically and transversely throughthe machine in the plane indicated by dotted lines w m, Fig. 1. Fig. 3, Plate 2, is an elevation of one end of the machine. Fig. 4, Fig. 5, Plate 3, is an elevation of one end of the machine. Figs. 6, 7, 8, and 9, Plate 4, are different views in detail of the swaging devices.
Similar letters of reference indicate corresponding parts in the several figures.
This invention relates to devices for swaging teeth for cotton and wool burring, whereby the edges of the teeth, as well as their gullets, are left perfectly smooth and free from fins. The devices hitherto employed for this purpose leave a flash or thin fin on each tooth, which requires to be removed by a subsequent operation. By my invention each tooth passes from the punch which forms it beneath swagin g tools or dies, which compress it both laterally and vertically in such manner as to give it the proper shape and leave it smooth and finished, as will be .hereinafter explained.
The following description of my improvement will enable others skilled'in the art to understand it.
In the accompanying drawing, A represents the main frame or table of the machine, and B the driving-shaft, which latter is arranged horizontally beneath the top of the frame A, and
. carries an eccentric, b a side cam, b, and a cam, b The eccentric b communicates a rectilinear reciprocating motion to the punching tool-stock N through the medium of a rod, a, and a bifurcated lever, a, which latter is supported by a horizontal shaft, 0, and connected to the stock N by means of an articulation, n, shown in Fig. 2. The cam b communicates a reciprocating motion to the swaging-bars J J through the medium of a lever, F, and two connecting-rods, s s. This cam acts upon an antifriction roller, g, which is applied to the lever F, and the latter has its bearings in abracket, g, depending from the top of frame A. The cam 0 which is outside of frame A and fixed on one end of the shaft 13, operates upon an anti-friction roller on one arm of a right angular lever, 0, shown in Fig. 5, which is held up by a spring, e and which has applied to its upper end a pawl, 19. This pawl 19 engages with a ratch et-wheel, r, on the shaft of a feed-roller, E, and at every revolution of the shaft B gives an impulse to thisroller. Alongside of the roller E is a corresponding roller, E, the peripheries of which are pressed toward this roller E by means of a spring, the force of which is regulated by set-screws 0 e ers E E the saw-blade is compressed and fed along as the work of punching and swaging progresses. The stock N of the punch slides in a box, 0, which is secured rigidly on top of frame A at right angles to a raised bed f, on which the saw-blade L rests. This stock N carries a punch, 0, corresponding in shape to the pieces to be punched out of the blade L, and it is guided and supported bymeans of a block, 0. Directly opposite the punching end of the punch c is a counter-die, which is an opening made obliquely through a block, 01, correspond ing in shape to the punch a. This counter-die is on one side of the bed f and the punch-block is on its opposite side, so that as the blank-. blade passes between them it will be supported on both sides while the punch operates to form the teeth on the strip of metal which is drawn between them through the guide f by the feedrollers E'E. Between the punch a and the feedrollers E E devices are applied for swagin g the teeth and furnishing them ready for use with out further manipulation. I will now describe these devices, which receive their movements from the main shaft 13, the arm F, connectingrods 8 s, and an adjustable cr0ss-bar,s, which latter is adjusted for stroke by means of setscrews y applied to the slotted head G I G represents a frame which is secured on top the frame A, and which consists mainly of two inclined parallel guides, between which the swage-bars J J play up and down. The under surface of the upper guide of frame G termin- Between the two rollates at its lower end in a shoulder or inclined plane, 2, which may be adjustable by means of a screw, 3. Both of the said guides are slotted at their lower ends so as to straddle the raised bed f, on which the saw-blade'is drawn through the machine. The swagebar J is articulated to the bar J .by a joint, 2', so that this bar J can vary its parallelism with respect to bar J. Between'the two swage-bars is a spring, w, which keeps the bar J up against the upper guide of slatted so as to straddle the saw-teeth, while the lower ends of the swages are so formed as to completely imprison the teeth between them i when they descend upon them. In the drawing, Figs. 8 and 9, I have represented the forms of grooves 7 '8 10, which are made into the swages to receive and finish the teeth. The swages in descending will travel in parallel lines a short distance, when the tool-holder J will encounter the shoulder 2, so that during the remaining part of the stroke the swa-ges will be forcibly pressed together at the same time they complete their downward movement.
' This compression has the efl'ect of perfectly roundin on c-Jr ers and burrs left in the tooth by punching. l
I will now briefly describe the general operation'of the machine. A strip of metal, L, of
proper width and thickness to form a saw, is fed into the machine through guide f and upon the raised bed f. The shaft 13 is rotated and the punch driven through the strip L once (luring each revolution of this shaft; at the same time the strip L. will be automatically moved proper distances by the feed-rollers E E for the teeth to be formed. After the teeth are punched they pass beneath the swages, which descend and swage their ed and points, leaving them rounded and smooth;
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is V 1. The swage-carrying bars J J, working between inclined guides of a frame, G, in combination with the shoulder 2 or its equivalent,v
substantially as described. 7
- 2. The swage-bar J, connected to the bar J by a joint, i, in combination with the interposed spring w and the shoulder '2, substantially as described.
3. The relative arrangementof punch c, swage-bars J J, and feed-rollers E E for punching and swaging saw-teeth, substantially as described.
