ing and repairing leather belting for machin cry; and it consists in certain improvements in machines of this class, as hereinafter described and claimed. 1

In the accompanying drawings, Figure 1 is a plan view of a belting-machine provided with my improvements. Fig. 2 is a side View of the same. Fig. 3 represents a section taken on line a: of Fig. 1. Fig. arepre'sents a section taken on line y y of Fig. 1. Fig. 5 is a plan view of a punch-block. Fig. 6 is a plan showing certain details in the punch-block and connections.

A designates a frame,to the inner and opposite sides of which are secured the longitudim l racks a, underv which are the fixed lon gitudinal guides b for a sliding frame which carries a cutting-blade, as hereinafter mentioned.

13 indicates a table which has pivotal connections c with said frame and is adjustable in its inclination by means of a cam-shaft d, extending under the table and having bean ings in the frame. The shaft clmay be turned 1 nd fixed'in position by means of a lever d" on the extended end of the shaft and a red: 9, which is fixed to the frame. A corrugated eccentric-roller f is journaled in the frame and provided with a hand-lever f, the purpose of said roller being to clamp the belting when being out against a base-board c.

A sliding frame is formed of the uprights O, which areconnected by cr0ss-rods at the top and are provided with cleats at the bottom, which extend into the guides 17. To the uprights O at their lower extremities is fastened a cutting-blade D, which extends across the table and is in position to cut the leather belt ing on the table B with a shearing cut.

E indicates a roller, which extends across Serial No. 316,214. (No model.)

the table B and is loosely connected by rods gwith theuprights C of the sliding frame, said roller being intended to rest on the belting in front of the blade D to keep the belting fiat against the table during operation.

F indicates an arm or additional frame, which is located at one side of the frame A and somewhat elevated, as shown. A headblock G is carried by the arm F, and two 6c punches h and h. are mounted in the headblock, being passed through perforations in the same. The punch h is formed to punch holes in the belting :forrivets, and the punch 'h is adapted to stamp the rivets severally as they are passed into the holes made by the punch h.

Within the head-block G. is also mounted a cross-form or T-shaped connection on, which through a slot in the casing of the head-block, and by a spiral spring 8 on the lower stem of the cr0ss-form, which extends through an aperture in the bottom of the head-block. Two vertical arms are carried by the crossform on, being pivoted thereto at h The said arms is extend upward nearly to the top of the head block and downward through openings in the bottom, as shown, the lower ends being provided with jaws 1', extending 8o laterally therefrom an d being adapted to hold a rivet between them. From the jaws '5 extend two curved guides '11 for the purpose hereinafter set forth. The upper ends ofthe arms is are bent toward each other and are connected by a spring 11 which tends to press them apart, and consequently to close the jaws v at the lower ends of said arms. Two screws 01 n are set in the top of the head-block in position to impinge against the beveled surfaces on the upper ends of the arms lo when the latter are raised by the action of the spring 5- on the crossform, the upper ends beingthus pressed together and the jaws i be ing opened. 5 The punch h, which stamps the rivet, is in position over a point between the jaws 2', where the rivet is held by said jaws, and both of the punches are sustained by springs 0, which raise them after being driven downward. The head-bloc1r is provided with a handle g, by which it may be moved forward and is heldin position by a screw m, passed 70 v backward to bring the punches each to the right point to be driven.

The face of the punch-block G (shown in plan in Fig. 5) is provided with a slot ,2, over which each of the punches is brought to be driven-one to make the hole in the leather and the other to stamp the rivet. It is also provided with a way for the slides '1' and 4*, which are placed therein, and an aperture v for the passage of the burrs to be used with the rivets, as hereinafter stated. A covering of sheet metal sis placed on the punch-block to keep certain parts in place, openingsbeing made in the covering over the slot 2 and the aperture 11/.

The head-block G is connected by a rod '1) with apivoted lever I, to the lower end of which'is attached a rod 19, which is connected with a stock or stud r, projecting down from the notched slide 0", which moves in the face of the punch-block. An edged tool r is carried by a rod 19 which is loosely connected with'the rod p',the said tool 0" being held in position with its edge in the slot 2 in the punch-block. The rod. 19 is provided with an elbow p and an arm 19, as seen in Fig. 6, and is so connected with p that when the latter is moved in either direction by the movement of lever I a slight similar movement is imparted to the tool W. A rod or wiret is fixed in position within or under the punch-block, the free end of the rod being turned up to the aperture '22 in the block. On the rod t are placed the burrs t, which are to be set with the rivets, the said burrs being pressed up through the aperture v against the plate 8 by a spring it, which is placed on the. rod. The uppermost of the burrs is then in position to be pushed along by the movement of 'the slide 0", as hereinafter stated.

H indicates a pivoted arm, which extends over the head-block G and is provided with a contact-surface 10 to rest on either of the punches h h when they are severally driven.

J indicates a striking-hammer, which is carried by a pivoted arm H, which extends over and is on the same vertical plane with the arm H. A hook h is pivoted to the arm of the hammer J, and when the arms H H are both raised the hook hconnects with a catch h on the arm H, and both of said arms are thus held in the raised position shown in Fig. 2. One of the punches being then brought in position to be driven, the arm H is pulled downward, being thus released from the hook 722, and rests at 11. on the punch, when the hammer falls, striking the arm H and driving th punch.

K indicates a magazine or inclined way for the rivets, which is formed of two parallel strips fixed in position adjacent to the frame F, the rivets being placed with the heads to said frame, with the shanks between the parallel strips.

From the jaws i on the lower ends of the arms 7c extend two curved guides 97., which are turned to the lower ends of the strips forming the inclined way K and are adapted to receive the rivets therefrom and conduct them to said jaws. The rivets are moved'one' at a time from the magazine K to the guides 'n by a pivoted notched block L, which is actu ated by a tongue 10, which is made fast to the head-block G and moves therewith;

The sliding frame, which carries the cutting-blade D, is moved on the guides 19 by means of a shaft M,.provided with a crank and gearing N, carried by said frame, said gearing connecting with the racks a. v The table B is adjusted in its inclination by means of the cam-shaft (I, so that as the frame which carries the cutting-blade moves forward a diagonal shearing cut is made through i the belting toward the edge of the table, Where the belting is out 01f, the end being thus formed for a lap. The two. ends of the belt thus formed are placed one over'the' other. on the punch-block, and the hammer israised to its elevated position by means of the pivoted arm H, being retained in such position by the hook it? The head-block G is then pushed back by meansof the handle 9, bringingthe punch h to position over the slotv z in'the punch-block, suchmovement actuatingfithe slide 0' through rods 19 '1) and pivoted lever I, and the said slide pushes the uppermost of the burrs 15' into position over the slot 2', so that the punch h when driven willpass through the;

rolled down the said guides into its seat in the jaws 71 under the stamping-punch h. The head-block being then drawn forward brings the punch 77/ and the rivet to position over the hole made in the leather by the punch h,

such movement bringing the tool 'r by rods p p under the rivet, the edge of said tool being in the slot .2. The punch h being then driven by the hammer, as before described, forces down the jaws and rivet, the latter .be ing driven through the hole in the leather and through the burr, and the jaws, being spread apart by the punch as they strike the leather, are raised by the spring 3. The arms k, which carry the jaws '5, come in contact at their upper ends with the screws n n, by which the upper ends are moved toward each other sufficiently to open the jaws to receive another rivet. by contact with the edge of the tool r sufiiciently to hold the parts of the belt together, and after enough rivets have been set in the manner described the belt is turned over and finished in the ordinary way.

The slide 1', with the hole it, isused in com nection with the punch h when it is desired to punch out rivets from a belt to take the IIO ends apart. The head-block is moved to bring the punch h over the hole a, and the belt is placed with the rivet under the punch, which is then struck with a hammer. The slide 7' may be drawn out when it is desired to take out the tool r 1. In a belt-machine, the combination, with a frame provided with horizontal guides, of a movable frame provided with a cutting-blade D, a pivoted table B, and means for adjusting said table in inclination, substantially as and for the purposes described.
