SAW-SWAGING MACHINE.

SPECIFICATION forming part of Letters Patent N0. 438,861, dated October 21, 1890.

Application filed December l0, 1889. Serial No. 333,265. (No model.)

To all whom it may concern:

Be it known that I, ELISHA B. RICH, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in AutomatieSaw-Swages, of which the following is a specification.

My invention relates to automatic sawswaging machines, and has for itsobject to provide a cheap, simple, and convenient machine.

My invention is illustrated in the accompanying drawings, wherein- Figure 1 is aside View of the machine. Fig. 2 is a plan view; Fig. 3, a cross-section; Fig.- 4, a detail view of a portion of the saw feeding and shifting mechanism. Figs. 5, 6, and 7 are enlarged details showing, respectively, the first, second, and third positions of the swaging devices proper in operation.

Like parts are indicated by the same letter in all the figures.

A is the bed-plate or table of the machine,

supported on the legs B B and provided with a hanger C, on which is secured the block C', vertically adjustable by means of the screwrod C2 and hand-wheel C2. On the block C is secured the slotted bar C4 to receive the saw C5, and on this bar is adjustably secured the arm C6, having at its upper end the pressure-block C7, which normally holds the saw in the position indicated in Fig. 3. Secured upon the table is the bed D.

E is the driving-wheel, loose on its shaft and provided with the clutch E', adapted to be engaged by the clutch E2, which is secured on the driving-shaft E3, so as to slide thereon but rotate therewith. This clutch is secured to the cross-rod E4, which terminates in the handle E5, projecting beyond the face-plate E6. By means of this handle and rod the drivin g-wheel may be thrown in or out of connection with the driving-shaft. The drivingshaft carries the pinion F, which meshes with the gear F on the shaft F2. This shaft also carries the eccentric F3, which drives the pitman F4, connected to the arm F5 on the rookshaft F6. On the opposite end of this rookshaft is the arm F7, to which is adjustably pivoted the feed-finger F8, adapted to engage the teeth of the saw C5, and thus successively feed the same forward tooth by tooth. On

the Wheel F is secured the cani-piece G, adapted to engage the rod G which. passes transversely through the table A and engages the inner side of the saw C5. This rod when moved toward the saw by the cam G operates in opposition to the spring C6. On the faceplate E is pivoted at H the hanger H, having the rear finger H2 and the lower removable swaging-tooth H3, shaped at its lower extremities substantially as shown. On the shaft F2 and outside the face-plate is supported the eccentric-roller H4, rotating between the finger H2 and the hanger H. The normal position of the hanger, roller, and shaft is adjusted by means of the sliding block H5, in which the shaft is journaled, and the controlling set-screw H6.

HT is a guide-piece bearing against the hanger and roller to keep the swaging-tooth in position against the face-plate.

J is a pinion on the shaft F2, meshing with the pinion J on the shaft J2, which is journaled in the face-plate, and the outer end of which J 3 is out at one side to serve asa rotatswaging-tooth H2.

The use and operation of my invention are as follows: The saw is placed in the grooved rest or piece C4, the same being adjusted by means of the hand-wheel C3 to such position as may be necessary to bring the teeth of the The saw is here normally held in the position indicated in Fig. 3, or in the line of such swaging parts. As the machine operates, the parts are so adjusted that when a tooth has been swaged the end of the rod G is engaged by the cam G and the saw bent out of the line of the swaging-dies in opposition to the action of the spring C6. At the same time the parts are so adjusted that the feeding-tooth FS performs its excursion and feeds the tooth next to be swaged past the die Whileitis thus bent out of the line of the dies, and thus the rod is released from the cam and the saw restored to its normal position, the next tooth being substantially in the position indicated -in Fig. 5. The clutches E E2 being in Contact, the rotation of the shaft F2 continues and the cam-roller or eccentric H4 rotates, as does also the shaft J2 and end thereof J3. This rota.

tion swings the tooth H3 forward, and thus ing swaging die or anvil in opposition to the saw in the line of the swaging dies or parts.

brings the parts into the position indicated in Fig. 6. A continuation of the same motion swages the saw-tooth, as shown in Fig. 7, and a continuation of the same motion releases the saw-tooth by swinging back the swagingtooth H3, with its hanger H. The process of feeding the saw last above described is now repeated and the next tooth brought between the sWaging-dies. The screw HG may be operated to move the block H5, and thus set the eccentric H4 to an exceedingly nice adjustment. Vhen the sWaging-tooth H3 is worn or injured, it may be removed and another attached to the hanger H.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is as follows:
