SAW-SWAGING MACHINE.
EPECIPICATION forming part of Letters Patent No. $73,74 dated Hovember 1887- Application filed June 29, 1887.
T 0 all whom, it may concern.-
Be it known that I, GEORGE M. HINKLEY,
of Milwaukee, in the county of Milwaukee and chines, of which the following is aspecification.
My invention relates to. machines for swaging the teeth of saws, and is designed more particularly for operating upon band saws, though not restricted thereto.
The machine consists, essentially, of a supportingframe, feed rolls for advancing the saw-blade one tooth at a time, clamps for grasping the saw when the tooth to be swaged is in proper position, a roller and a die which descend one in front and the other in rear'of the tooth, the die acting upon the tooth, throwing its point slightly forward and sustaining it while the rolier ascends and spreads the point laterally, and mechanism for imparting motion to the several parts in proper timeand order, as hereinafter explaiuetl.
The elements and combinations which are deemed new will be pointed out in the claims.
The construction of the machine is illustrated in the annexed drawings, in which Figure 1 is aside elevation of the complete machine; Fig. 2, a top plan view; Fig. 3, a horizontal section on a planejust below the bed or table of the machine; Fig. i, an end view of the machine; Fig. 5, a perspective view of the head or upright portion of the frame containing the swagingslide, its guides, and the saw-clamps; Fig. 6, a. rear view of the same; Fig. 7, a view showing the construction of said clamps.
Aindicates the bed or table of the machine, supported by legs or standards B, and provided on its underside with hangers C and D,
the former having boxes (1. for a main driving- Serial No. 212,856. (No model.)
jaws, and the swaging devices. The feed-rollers H H are two vertiealrolls, advisably covered with rubber, leather, or other suitable material, to take a firm hold upon the sawblade and carry the next tooth forward against the swaging-roller, while at the same time avoiding injury or defaceinent of the blade.
The roller shafts 01' arbors are carried at their lower ends in adjustable boxes (I, which are secured at any desired adjustment by setscrews 0, one box being set toward the other by means ofa screw, I, the stem of which extends out beyond the side of bed or table A, and is furnished with a handwheel, as shown in Fig. 2. The upper ends of said arbors are likewise provided with boxes orjournal-blocks f, to one of whichis hinged or pivoteda yoke, J, carrying a screw, K, provided at its outer end with a handwheel by which to turn it.
\Vhen it is desired to enter between the rollers a saw-blade which cannot be conveniently passed endwise between-41s, for instance, a gangsaw blade provided with tabs for secur ing it in the sash, or a bandsaw blade, which of course could only be entered transversely to its lengththe screw K is turned baclgand, if necessary, the screw I also, the yoke J is thrown up, the blade is passed down between the rollers, its toothed edge uppermost, and then the yoke is brought back to its normal position, and the screws are tightened to give the desired pressure of the rollers upon the saw-blade. It is necessary that the blade be advanced by a step-by-step movement, and that each advance be exactly equal to the distance between the points of successive teeth, so that each tooth may he brought to the exact position required for the proper operation of the swaging devices. To accomplish this the arborsgg of the rollers H H are provided with gear-wheels h h, of like size and number of teeth, and one of said arbors is further provided with abevel-piniomi, which meshes with and receives motion from a like pinion, j, carried by the shaft G.
Keyed or otherwise made fast upon shaft G is a ratchet-wheel, L, and swinging freely upon the outer end of said shaft is a yoke, M, having an arm, M, furnished with a dog or pawl, Z, which alternately rides back over and engages with the teeth of ratchetwheel L as the yoke swings to and fro. The swinging or oscillating motion of the yoke is effected by cam 1, acting through the medium of a grooved block or runner, N, which clasps or straddles the edge of its irregular rim, a pitman or connecting rod, 0, and apcndulouslink or hanger, P, which latter maintains the block or runner and the end of the pitman attached thereto at the proper height.
In order to provide for varying the feed of the saw-blade, the yoke M is furnished with a sliding block, m,to which pitman O is attached, and said block is provided with a threaded hole, through which passes an adjusting'screw, n, swiveled in the yoke, and provided with a hand-wheel by which to turn it. By turning the screw the block may be raised or lowered, and the throw of the yoke and consequent movement of the ratchet-wheel and feed-rollers proportionately increased or diminished.
The cam 1 is of such form that the parts actuated by it perform their movements while the swaging devices are at rest, and that said parts remain at restwhile the swaging devices are in action.
The mechanism for clamping the saw-blade preparatory to the acting of the swaging deviceswill be better understood upon referring to Figs. 1, 2, and 4. Asshown in said figures, two standards, Q, are bolted to and rise from the bed or table A, said standards being formed with recessed or box-like portions Q, which extend inward toward each other from opposite sides of the vertical plane in which the saw-blade is held and moves.
Within the box-like portions Q, which are covered by plates or caps Q", areplaced clamping-jaws R R, designed and arranged to clamp the saw-blade between them and to hold it firmly while undergoing the action of the swaging devices. The jaw R- is pressedinward toward the plane in which the saw-blade moves by means of two set-screws, S S, audit is held against moving toofar inward or is drawn back by means of an intermediate screw, S. The other jaw, R, is required to advance and recede quickly after each advance of the sawblade to clamp it for the action of the swaging devices and to release it for feeding forward after such action. To effect such movements I provide a vertically-moving bar, T, between which and the rear or outer end of jaw R, I place two links or bars,0,which are pivotally at tached at their ends to the bar T and to thejaw, respectively, said links approaching more or less nearly to a horizontal position as bar T moves longitudinally. The rear or outer face of bar T bears against a block, U, adjusted like jaw R by means of screws S and S, said block being held rigidly in any position to which it may be adjusted. The vertical move ment of bar or slide T is unvarying; hence it follows that upon the adjustment of block U will depend the distance between the jaws R and B when the latter is forcedinward by bar T and links 0, and in this way the jaws may be made to clamp blades of different thicknesses. The rising and falling motions of bar T are produced by means of cam 2 on shaft E, acting through the medium of a lever, V, pivoted at one end upon shaft F and furnished at its other end with a block or runner, p, which clasps or straddles the laterally-proj ecting rim of the cam, the lever V and bar T being connected by a link, q, Fig. 1.
The swaging mechanism consists,essentially,
downwardly-extending arms 1', curved in an arc of a circle. concentric with the roller WV when the latter is in position to spread the point of the toot-h, and these arms fit nicely within grooves s, of like curvature, formed in arms t, extending upward from the standards Q, as shown in Fig. l. The armsfare pierced to receive clamping-bolts u, the inner ends of which are bent horizontally at a rightangle to pass in frontv of the arms r and to bear against the inner faces thereof when the nuts u, applied to the outer ends of the bolts, are turned up to draw the bolts tight. In this way the arms 1", and consequently the standards Z, are held rigidly at any desired adjustment, the angle of inclination of the standards being varied by swinging the same forward orbackward, as required.
Owing to the curvature of the arms 1' concentrically with the roller WV when the latter is in its working position, it will be seen that the adjustment or variation of inclination of the arms and the standards Z will not affect or alter the central working position of said roller. The slide Y is formed with an outwardly-projecting lug or ear, to which is jointed a pitman, A, the lower end of which is made in the form of an open frame or yoke, in which is placed a sliding block, B, carrying a stud or pin, 10, which enters a hole in one end of a lever, O, pivoted or hung at a point between its ends in hangers y and furnished at its other end with a block or runner, m, which fits upon or clasps the laterallyprojecting rim or flange of cam 3. The block B is tapped to receive an adjusting-screw, D, swiveled in the yoke or open frame of pitman A, as indicated in dotted lines, Figs. 1 and 6, so that by turning the screw the block may be raised or lowered, and thus the points to which the roller may rise and fall may be varied to suit the width of blade'and the size of the teeth operated upon. The cam 3 is so'formed and placedwith reference to cams 1 and'2 that it lowers the slide Y before the feed or advance of the blade is entirely completed and while the clamping-jaws R R are closing upon the blade, the movement of the slide terminating when or j ust before the jaws begin to form mentioned to permit it to straddle thesaw-blade. Sctscrews 3 serve both to adjust and to clamp the die E in place, and also permit it to be readily removed and replaced when necessary. The lower end of slide or die-carrier F is connected by a link, 2, with an arm, a, projecting from a sleeve, b, encircling shaft F, and provided with a long arm or lever, c, furnished at or near its free end with a sliding block or runner, d, which clasps or straddles the horizontally-projecting flange or rim of cam 4. The cams l, 2. 3, and 4 being all secured upon one and the same shalt, and being made to give all requisite motions to the working parts, it follows that alter the cams are once properly adjusted and made fast upon the shalt the motions of the parts will of necessity take place in unvarying order and time. To retain thelink z in vertical position its lower end is provided with an arm, 2, which extends down below the point of attachment to arm a, and is furnished with a ball or weight, 2 i
G indicates a post or stem, the upper end of which is slotted to receive, guide, and support the back edge of the saw-blade. This post is fitted in a hole or opening in the bed or table A, in which it may be raised and lowered, as required, and is clamped at any desired height by a set-screw, e.
\Vhilepassing through the machine and be ing acted upon by the swaging devices the saw-blade is supported by a bearing-block or anvihj", the under face of which is inclined longitudinally and rests upon the correspondingly-inclined face ofa lower block, 9. Thus formed, the saw-support may be raised orlowered by moving the block f longitudinally upon the block 9'.
lVhen a saw is too narrow to bring the teeth in proper working position by means ofblocks f and g',block 7' may be raised and a block of sufficient thickness, with parallel faces, be inserted between bed A and blockg, to bring the points of the teeth to the desired height.
