To (ZZZ whom it may concern Be it known that I, FRANK B. FREEMAN, a citizen oithe United States, and a resident of Dayton, in the county of Campbell and State of Kentucky, have invented certain new and useful Improvements in Machines for Reinforcing Insoles, of which the following is a full, clear, and exact description, reference being had to. the accompanying drawings, forming part of this specification. My mvention relates tomachines for pressing in the canvas of reinforced insoles around the upturned lip thereof. In machines of this character, it is very desirable to have a light structure, silently running,

and easy to operate. Also in tucking the canvas around the upturned lips of insoles, it is desirable to have not only one movable tool working up against the insole lip on the inside, but also to have a tool or tools workthe lip also. In machines oi this character, in the past it has been founddifiicult to provide the proper motion 'for the pressing-in tools without complicated mechanism, and it is desirable to simplify the method of obtaining this motion.

Accordingly it is the ob ect of my invention to provide a machine of the character mentioned which is light and silent running.

It is also an object of this invention to provide for the motion of the pressing tool by a simple vibrator in combination with a cain and spring, thereby greatly simplifying the mechanisms of the past.

Again it is the object of this invention to provide for oscillating tools on the out said tools being actuated by the same device which moves the inner tool, the motion of these outer tools being such as to cooperate with the inner tool to accomplish the most effective and smooth pressing down of the canvas around the inside lip.

These objects, and other advantages to be noted as the description proceeds, I accomplish by that certain construction and, arfgrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawings, Figure 1 is a top plan view of the machine, with the operating ting the edge of the insole and v the eccentric stud at mechanism removed. Fig. '2 is a side eleva tion thereof. Fig. 3 is an enlarged side elevation of the pressing-in tool. Fig. 4 is a perspective view of the lower plate for abutsame through the machine. Fig. 5 is a diagrammatic plan view showing the cooperating action of the various pressing or tucking-in tools.

The base plate 1 of the machine is mounted on a standard 2 of suitable character, which is preferably low so that the machine can be set up on a working table or bench. This base plate has a T-slot in its upper surface; said plate having the cross portion 3 of the slot extending through the plate from one side to the other, and the longitudinal portion 4: of the slot extending forwardly to the front of the plate. On this base plate is mounted the top plate 5 which supports a vertical shaft 6. This shaft is caused to rotate by any desired mechanism such as the pulleys and belt 7 and 8 respectively, although this is not an essential part of my invention. 2

Mounted in the T-shaped slot between the two members is a T-shaped bar, having the lateral member 9 and the forwardly extending member 10. Thebar has a longitudinal slot 11 in it, and in this slot is set a square block 12, having a hole 13 in it to receive the end of the shaft 6. It can thus be seen that as the shaft rcvolves, the T-bar will befcaused to reciprocate or vibrate in the slot. On an extension 14 from the top member is mounted an antifriction roller 15, which contacts with the upper surf to of the T-bar through a slot in the said top member. Mol ted on the forwardly extending end of the bar member 10 is a block 16, which has pivoted in a groove in its outer facethe pressing-in tool 17. This block has alsoa transverse groove 18 in its rearward face, whereby it is mounted over the end of the T-bar, a removable screw 19 or the like serving to secure the mounting.

A plate 20, having a cam edge 23'. is

guiding the mounted on top of the extension 14, and the roller 22 on the upper end of the tool 17 is spring-held against this edge by the spring 23. This cam edge 21 slants from front to rear, and it is plain that as the T bar memgage on' the inside of the lip 25 and press or .iron the canvas 26 of th insole firmly into the crotch of the lip. Extending down from the rear, end of the tool holding member 16 is a'plate 27, having asloping outer face 28 that engages the outside of the insole lip,

thereby backing up the movement of the claw 24and imparting the proper slant to .the insole lip. There are thus two ironing or pressing members, one moving toward the other, and the canvas is not hammered against the lip but is smoothed and ironed.

' into place.

Mounted on the under side of the base portion 1 of the machine is a plate 29, having a beveled edge 30, which extends out so as to contact with the shoulders of the lip 25. This plate serves as a guide for the insole through the machine, and is adjustably mountedby means of the slots 32 and the screws 33 for securing it to the machine base. Mounted on an arm34 extending forwardly from the standard to the machine is a our- -nal member 35. A shaft '36 extends through this journal member and is pushed upwardly in said member by a spring 37 housed within the journal. At the lower end of this shaft are nuts 38, limiting the upward movement of the shaft and a hook 39 engaging with a foot treadle. On top of the shaft is a table 40, which extends up beneath the tool 17 ,and over, this table the insole is passed during the operations of the machine. Theplate 29 also extends out over this table, and it is obvious that for inserting the work in the machine it is not necessides of the base 1, and are held downwardly by springs 45. These rods bend inwardly and downwardly at 46 to a position, one on one side and one on the other side of the plate 27 of the tool holder. As the bar is vibrated, first one and then the other of the rods 43 are tipped'at the rear. causing the forward ends 46, 4(5,to come down and contact with the outer edge of the insole. just outside of the lip thereof.

The operation of the machineis then as follows. The T-bar is caused to vibrate by rotating the shaft 6, the table is lowered and an insole with canvas aflZiXed to it is inserted at the side of the machine. The end 30 of the plate 29 then serves as a guide at the edge of the insole. and the plate 27 rests against the outside of the lip. The first member to strike the insole in any sequence I of operations is the rod 43 nearest the operator, which pulls the canvas well over the lip 'of the insole. The claw 24 then comes in against the inside of the insole, against the edge 28 of the plate 27 and simultaneouslythe other outside rod 43- comes down and cooperates with the claw in firmly tamping the canvas down around the lip. The forward movement of the claw in a diagonal line serves to feed the insole over thetable, and it is unnecessary to provide means to revolve the table. The two outer tamping members serve the purpose of completely smoothing and pressing down the canvas on the outside of the lip. For insoles having the lip at different positions in from the edge of the leather portion of the insole, the plate 29 isto be shifted so as to change the position of the outer abutment.

Various modifications are possible in this machine Without departing from the-spirit of theinvention, and it'is not desired, by reason of the omission ofmention of such modifications, to limit the claims that follow beyond the full scope of equivalents,

where the wording ofthe claims does not said member, and means for maintaining one end of said tool against said abutment, to give its working end a diagonal movement toward the lip of an insole being operated upon.
