SHOE-HEEL-ATTACHING JACK.

Application lled May 16, 1928.

This inventionY applies to shoe jacks, such as are used to hold a shoe and a heel in assembled relation, for the purposeof securing the heel to the shoe. This application is a continuation in part of application S. N.

247,806, filed January 19, 1928, as to comnion subject-matter.

O ne of the objects of this invention is to provide a jack, by means of which a heel vmaybe clamped to a shoe in adjusted posi-v tion and securely held in that position while the heel is nailed-to the shoe.

Another object is to provide such a jack in which the heel may be placed on the shoe in inverted position and clamped and then the vjack reversed, so that the nailingl may be carried out from the inside of the shoe.

y Another object is to provide such a jack which will support the shoe in convenient position and which may be turned about in order' to provide access ito all sides.

Another of the objects of this invention is to provide ay shoe jack which will hold the heel in lirin engagement with the shoe in such a way as to avoid slipping during the fastening operation. v l

Another object is to provide such a shoe jack which will support the heel in adjusted position relatively to the shoe while the jack itself is being tightened to clamp the heel to the shoe.- Y

Further objects will appear from the following description, taken in.. connection with the accompanying drawing, `in which- Figure 1 is a side'view of a jack embodyf ing this'invention, in position for adjusting the heel` in place on the shoe;

F igure 2 is a similar view, showing the jack inverted and positioned for securing the heel;

Figure Figure 1.

Referring to the drawing, 1 designates a base having a socket 2. The jack itself comprises a C-clamp body 3 having an abutment 4 adapted to receive the heel tread. The opposite portion of the body is provided with a clamping screw 5 adapted foi-'adjustable engagement with a flaring socket in a clamping block 6 placed inside the shoe, as shown in Figure 1, so as to clamp the same against the heel. The block 6 may be provided with nail guide holes 7 through which 'na-ils may be inserted for driving into the heel.

the shoe. In order to avoid this difficulty a stop 8 is adjustably mounted on the body 3 so as to'be slidable therealong. rThe body and the stop 8 are provided--With'matching teeth or corrugations 9 adapted to prevent the s top from slipping under the pressure appliedby the, clamp.

The screw 5 may be provided with an op erating handle l10 :and ,with a. shank 11 adapted to fit the socket 2. The opposite end of the body 3 is also provided with' a similar shank 12. y

In the use ofy this device, the cam block 6 is placed on the end of the screw 5 and the shoe adjusted thereon to its proper position. The heel is then placed ,in proper position on the shoe and thescrew 5 operated to .bring the heel tread properly against. the abutment 4, only a light clamping pressure being applied. The stop 8 is now lowered to position to engage the rear portion of the heel near the point where lit engages the shoe. The clamping screw 5 may now be tightened so as to clamp the heel and the shoe securely together. During this operation, the stop 8 prevents any slippingr` ofthe heel on the shoe and, accordingly, the heel is retained in proper adjusted position and is tightly clamped in that position. The body 3 is now inverted to the position shown in Figure 2, theshank 12 being inserted in the socket 2. In this positionV theshoe is held upright with the open side up, so as topermit access to the interior thereof for the insertion of fasteners to secure the heel to the shoe. With the clamping block 6in this position, nails may be inserted in the holes 7 and driven home by means of a'suitable nailing` tool 13. When the heel has been properly secured, the clamp is loosened. This releases the pressure onthe stop 8, which drops of its own weight so as to free the heel and be ready for the subsequent operation.

It will be noted that the inner web 17 of the body 3 is terminated adjacent the end of the body, so as to provide a section 18 of said body without they web 17. v'Ihisis in a socket, a C-clamp bodyl having an abut.

order that the tool 13 may be brought close to the center line of the body 3,'in-order-to drivefthe nail'in the rearmost `-passagef7, which is usually in the middle of the heel. The presence of a web 17 at this point would interfere with the operationl ofthe tool 13S It will be seen, therefore, 'that this inve`n`- tion provides a very convenient device-for attaching heels to shoes. By mounting in upright position, asfiin Figure' 1,"-the heel and shoe may be quickly brought into their proper relative positions and` clamped in po sition. The device is then quickly'reversed to position for nailing.v A'Thevnail guides are easilyk accessible, and the clamp vmay -beturned about to any convenient position. VVhenthe nailing is complete, aturn ofthe screw 10 releases the-shoe and the device is ready for 'thelnext operation.

It will be seen that this 'invention accom--v ipl'shes its objectsin' providing a jack of simple construction, which not'only vclamps the heell and the shoe together in proper position', but whic'hprevents slippage of the heel after it has been adjusted' in position;

It is obvious 'that various changes may be made, within the y scopev of the appended claims, in the details of construction Without departing from the spirit of this invention; it is, therefore, to be understood that this 'invention is notlimited to' thespecific details shown and described.
