BOOT AND SHOE SOLE FINISHING MACHINE.

I SPECIFICATION forming part of Letters Patent No. 275,873, dated April 17, 1883.

Application filed August 30, 1882. (No model.)

To all whom it may concern:

Be it known that we, CHARLES R. WELLs and BENJAMIN K. LEWIS, both of Lynn, in the county of Essex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Boot and Shoe Sole Finishin g Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

Our invention relates to boot and shoe sole finishing machines, and has for its object to effect, in an expeditious and economical manner, the operation of imprinting ornamental designs upon the bottom surface of boot and shoe soles.

The invention consists in the organization of a mechanism for this purpose, as well as in certain details of construction, to be hereinafter more fully set forth and specifically claimed.

In the accompanying drawings, Figure 1 gives a side perspective of our invention. Fig. 2 gives a plan view thereof, and Fig. 3 is a vertical cross-section made through dotted line 00 00 in Fig. 1.

The treadle-lever B, having step or foot plate I) and counter-weight a, is pivoted, as shown, to the vertical column A, and enables the workman to reciprocate vertically the rod D, which is arranged to slide in the column A, its bottomend resting on the lever B, and it is prevented from turning in its bearings by any ordinary pin or lug, arranged to operate in a suitable slot or groove in the column. Said vertical rod D carries on its upper end the horizontal rod E, on the forward end of which is arranged the short vertical standard F, which, i

reaching upward, bears with its top end against the fore part of the shoe, thereby operating as a toe-rest for the same. It is arranged to slide on the rod E, and may be adjusted thereon by means of set-screw (I, so as to conform to the size and length of the different shoes.

At the rear end of the rod E is a vertical rod or block, G, which is connected with the rod E by pin-joint e, the tongue on the rod being set into a groove in the block in such manner as to allow the block to be tipped forward and backward, but to have no lateral movement. The springh, which bears one of its ends against the block and its opposite end against a boss on the rod E, operates to keep the block tipped forward toward the toe-rest F, as represented in Fig. I. Said block Gcarriesa heel-pin,f, the bottom end of which plays loosely in a suitable socket in the block G. The heel-pin itself, being mounted on the pivoting-pin a, (see Fig. 3,) permits ofa slight rocking movement laterally, while a flat spring, 122, attached to the end of the heel-pin fand to theinner end of the rod F, tends to keep the heel-pin vertically erect in the socket. It will now be understood that, for the purpose of j ackin g the shoe, the block G should be tipped backward, thereby contracting the spring h, and the shoe being placed in position, (by inserting the heel-pinfinto a hole in the last,) the block G is allowed to be tipped forward by operation of the spring h, so as to keep the shoe pressed down upon the toe-rest F. The heel-pinf, being pivoted on its pin a, permits a slight rocking of the shoe laterally, thereby enabling the shoe to better adaptitself to the shape of the imprinting-tool.

The design to be imprinted upon the sole is arranged upon the periphery of the arch or section of a-disk-wheel, H. I prefer to use the section of a wheel, as it enables me to get into the angle formed by union of the heel with the shank of the shoe, though for many classes of work the complete wheel would be equally useful. The designs may be engraved upon the wheel directly, or they may be engraved upon suitable pieces of curved metal and subsequently attached to the wheel by screws or other obvious means. upon a suitable shaft, M, so as to permit of sliding movementthereon,andis then mounted, as shown, in the frame N, which is connected at its bottom end with the column A in such manner as to be rocked back and forth on its connecting-pin. The metal band if connects the two sides of the frame, and by coming against the column A, in an obvious manner, prevents the frame from going back beyond the position represented by dotted lines in Fig. 1. The imprint is made on the sole by rolling the disk over the same while the shoe is being pressed upward by the weighted lever B.

The operation is obvious. If it is desired to Said disk is mounted.

ICO

ornament the sole close up to the breast ofthe heel, (in which case the arc of a disk must be used,) the tool should be started at that point and rolled outward. In some cases we have found it desirable to ornament one side of the sole only, or both sides of the shank, near the edges thereof, leaving the center thereof plain. In such cases the tool may be moved on its shaft to one side until only one edge thereof hangs above the shoe. One side of the shank of the sole may be operated upon with the tool in that position, and then, if desired, the tool may be moved in like manner to the opposite side of the shoe, and the other side of the shank operated upon with the tool in that position. By operating in this manner we are enabled to obtain a greater variety of ornament, as well as to operate on one side of the sole only, if desired. In some cases, too, we have found it desirable to cover certain parts "of the sole not intended to be operated upon by means of a shield. Said shield is composed of very thin metal, having any desired contour or figure, and is arranged directly upon the small rod 3, which itself is supported by the elbow-rod 4, and this in turn is arranged loosely upon the rod E, as shown in Fig. 1. The rod 4, being arranged loosely upon the rod E, permits of being turned thereon, so as to present the shield from the opposite side of the shoe whenevcroccasion requires. The properheight for the shield, which should be such as to allow it to bear upon the sole, is obtained by means of the rod 3 and set-screw 5, in an obvious way. A spiral spring, 6, operates to' force backward the supporting-rod 4, thereby keep ing the end of the shield pressed up against the breast of the heel. This shield is allowed to press down upon a portion of the sole covered thereby while the imprinting-tool is rolled over the same, the part being in this manner protected from receiving any impression of the tool. v

The imprinting-tool is to be rolled over the sole while heated quite hot, so as thereby to better impress its image upon the sole by coloring the leather at the points of contact. For the purpose of keeping the tool continuously heated while in use, we make use ofa ratchet-wheel, 7, which is mounted loosely upon the shaft M inside of the disk H, and with its periphery in sliding contact therewith. It is provided on its outer edge with a system of ratchet-teeth adapted to engage one end of the pawl 8, the opposite end whereof is pivoted to the frame N, so as to allow the said wheel to be turned in one direction only. From this it will be understood that as the disk H is turned in one direction to operate 011 the sole it carries the inner wheel round with itself; but when itis reversed in the opposite direction for the purpose of bringing it into position again, the pawl 8 cperates to prevent the inner wheel from turning therewith. The inside wheel is being constantly heated at the top by -means of the lamp 9, and this top or heated portion is being constantly brought down to the working part of the outer tool, in the manner described, and heats the same by contact therewith.

We claim- 1. In a machine for the purpose described, the combination of a wheel mounted on a swinging frame, and with a shoe-holding device consisting of a support, D, adapted to be pressed constantly upward, and a hinged jack, the partsbeing so constructed and arranged that the shoe, while being constantly pressed against the tool, is automatically adjusted to correspond to the varying positions of such tool, substantially as described.
