MAX HART, 0F CENTRALIA, ILLINOIS.

TURNEILSHOE-REPAIRING MACHINE.

To all whom it may concern:

Be it known that I, MAX J. HART, a citizen of the United States, residing at Centralia, in the county of Marion and State of Illinois, have invented certain new and useful Improvements in Turned-ShoeRepair ing Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvementsin shoe manufacturing and repairing means and 'more particularly to a device designed primarily for securing loosened soles of hand-turned shoes to the inwardly projecting portions of the uppers from which they have become loosened.

The object of the invention is to-provide a machine of this class which although being ofvery simple and comparatively inexpensive construction, will be quick and eflicient in operation and will drivethe nails used in repairing outwardly from the inside of the shoe through the aforesaid portion of the upper and then through the sole, into. contact with which they are clenched.

In reducing the invention to an operative machine, Iprovide the construction hereinafter'described and particularly pointed out in the appended claims, one embodiment of the invention being shown in the accompanying drawings wherein like reference characters designate corresponding parts throughout the several viewsand wherein:

Figure 1 is a side elevation of a machine constructed in accordance with my invention; Fig. 2 is an edge view; Fig. 3 is a vertical longitudinal section as seen on the plane'indicated by the line 33 of Fig. 2; Fig. 4 is a top plan view; Fig. 5 is a detail horizontal section as viewed on the plane indicated by the line 55 of Fig. 1; Fig. 6 is an enlarged top plan view of a portion of the last; Fig. 7 is a detail longitudinal section taken on the plane designated by the line 77 of Fig. 6 andillustratingmore particularly the disposition of the nail driving plunger in respect to the apertures in the last, and Fig. 8 is a perspective viewof one form ofnail driven by the machine;

In these drawings, constitutinga part of theapplication, the numerals 1 and 2 desig nate' respectively nail driving and nail clenching members movable simultaneously toward and simultaneously away from each Specification of Letters Patent.

Patented May 16, 191s.

Application filed May 13, 1915. Serial No. 27,877.

other, operating connections to be hereinafter described being provided for this purpose.

Interposed between the nail clenching member 2 and the driving member 1, is a last 3 having therein a plurality of openings 4 receiving plungers or fingers 5 which project from the aforesaid member 1 toward the member 2. It thus follows, that when nails are inserted in the openings 4 and a shoe is passed over the last and properly positioned thereon simultaneous movement of the two members Land 2 toward each other will cause the latter to force the nails through the openings 4 against any preferred type of anvil or clenching surface 6 with-which the member 2 is provided. By this manner of operation, it will be evident that the nails maybe driven outwardly through the inwardly turned part of the upper and then through the sole, into contact with which they are clenched, this process having been found to be much quicker and more desirable in every way than the present day methods of repairing hand-turned shoes.

In the present embodiment of the invention, the last 3 is shown as provided with a rib 7 on its under side received by a groove formed in the upper end of one arm 8 of a hollow U-shaped support 9, the other arm .10 of said support being extended to a point disposed in a plane abovethe last 3, at which point the clenching member 2 is fulcrumed between its ends at 11, said member being here shown'in the form of a lever of the necessary proportions provided atone end with ahandle 12, this end being disposed directly'above the last 3 and carrying the anvil 6. Thus it will be seen, that depression of the handle 12 by hand power or by striking the same with a hammer or the like, will force the anvil 6 toward the last 3 and into contact with the sole of the shoe disposed thereon. Simultaneously with this operation, the nails are projected through the part of the upper from which the sole has become loosened and through the sole by the plungers on the nailing member 1. This last named member is likewise shown in the present application in the form of a lever fulcrumed between its ends at 13 t0 the upper end of the arm 8, the end of this lever remote from the plungers 5 being disposed in the hollow arm 8 and being connected at an eccentric point with one end of the operating means 14, such means being here shown in the form of a cable confined within the hollow support 9 and having its opposite end connected at an eccentric point to one end of the lever member 2 remote from the anvil 6 thereof, a turn buckle or the like 15 being preferably provided intermediate the ends of the cable 14 for the purpose of tightening the same at will.

The entire hollow support 9 is preferably provided with an upright pivot 16 connecting it to a base 17 which may be secured to a work bench or to another appropriate support, this pivot allowing the active parts of the machine to be swung arcuately to a number of different positions as is common with devices of this general class. Furthermore, as is usually the case with nailing machines employing lasts, the same are interchangeable and may be of various shapes, sizes and designs, according to the style of shoe to be repaired. In some instances, provided additional lasts of proper construction be provided, they may be disposed over the last 3 already positioned upon the machine. Such minor details of construction, however, need not be illustrated in the present application.

Although the above described machine could be constructed for the driving of any preferred design of nail, I preferably employ that style shown in Fig. 8, this nail 20 .being in the form of a T whose shank 21 projects from its head 22 at a point spaced toward one end from the center thereof. Actual experience has roven that this type of nail will more e ectively prevent the parts of the shoe from again tearing apart, than other designs of nails which might be used. Therefore, the machine is preferably constructed for driving nails of this class.

From the foregoing description, taken in connection with the accompanying drawings, it will be evident that although an extremely simple construction has been provided for carrying out the object of the invention, the machine will be very efficient in operation and will possess a number of highly advantageous features. Particular emphasis is laid unon the fact that the nail driving and clenching members are movable simultaneously toward each other and simultaneously away from each other, and likewise upon the fact that the nails are t0- tally confined in the last until it is necessary to drive the same into the shoe, this being an extremely important feature but it is likewise important that when the machine is being used for the purpose above described, the numerous openings 4 be dis posed contiguous to the edge of the last, since by this disposition the nails will be effectively forced through the necessary parts of the shoe.

In addition to the previously described use of the machine, it may be used to advantage for repairing other styles of shoes, for fastening buttons on uppers, and in any one of the numerous manners in which those skilled in the art to which the invention relates may see fit to apply the same to use.

In the drawings I have shown certain specific details of construction for producing probably the best results, and in the preceding pages I have described such details, but it will be evident that I need not be limited thereto otherwise than to the extent to which the appended claims limit me.

I claim:

1. In a shoe nailing machine, a last having therein a nail receiving opening, an anvil above and movable downwardly toward said last, and a plunger movable upwardly through the aforesaid opening simultane ously with the downward movement of the anvil.

2. In a shoe nailing machine, a nail driving member and a nail clenching member movable simultaneously toward each other and simultaneously away from each other,

fulcrums for the two members, means to rock one of said members around its fulcrum, a cable connected at its ends to points on the two members eccentric to said fulcrums, and guiding means for said cable.

3. In a shoe nailing machine, a hollow U-shaped support, a nail driving member fulcrumed to one end of saidsupport, a nail clenching member fulcrumed to the other end thereof, the two members being movable simultaneously toward each other and simultaneously away from each other, means to rock one member around its fulcrum, and operating means for the other member confined in the hollow U-shaped support and connecting points on the two members ec centric to the fulcrums of said members.

4. In a shoe nailing machine, a hollow U-shaped support, a nail driving member fulcrumed to one end of said support, a nail 5. In a shoe nailing machine, a pair of supporting arms spaced one from the other, a last projecting from one arm and having therein a nail receiving opening, an upwardly movable plunger beneath the last and movable through the opening therein, a

downwardly movable anvil member above the last, means to force the anvil member toward the last, and operating means lead ing from said anvil member to the plunger for raising the latter simultaneously with the lowering of the former.

6. In a shoe nailing machine a hollow U-shaped support, a last secured to one arm of said support said last having a nail re ceiving opening, a nail clenching lever fulcrumed between its ends to the other arm of the support and having one enddisposed above the last, a nail driving lever fulcrumed between its ends to the support directly beneath the last and having a plunger disposed in the opening of said last, and an operating cable housed within the hollow support and having its ends connected to the said levers at points eccentric to the fulcrums of said levers.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
