invention to provide a clamp structure-which is ordinarily held in an open position to allow theclamp to be readily applied to the over-lapping 1 Claim. ((11. 13-103) Figure 4 is a cross sectional View of the clamp taken substantially along a plane as indicated by ,the linedl of Figure 1.

Referring more specifically to the drawing, the shoe sole clamp in its entirety is designated generally 5 and includes a bottom clamping bar, desportions of a shoe shank and shoe sole :by .holding the clamp with one hand thereby leaving the other hand free for properly adjusting vthe overlapping; beveled portions of the shank and half sole,= after which the second hand may be utilized for applying a uniform pressure to the clamp to displace the clamping elements, thereof toward one another sothatthe beveled edges of the sole another until operation of a manuallyactuated part for displacing the clamping elementstoward one another and intoclamping engagement with the sole and shank. I I

Stilla further object of the. invention is to provide a shoe sole clamp includinga yieldable mem-- ber carried by one ofthe clamping elements for engaging the outerside of the shoe sole and which functions in combination. with manually actuated cams to permit :the clamping elements to be displaced toward one another and into effective clamping engagement with the sole and shank. V 1 j Various other objects and advantages of the invention will hereinafter become -more fully V apparent from the following description of the drawing, illustrating a presently preferred embodiment thereof; and wherein:

Figure 1 is a side elevational view showing the 7 shoe sole clamp in an applied position but before the clamping elements have been displaced toward one another and ship;

Figure 2 is a top plan viewof the clamp; Figure is an end elevational view thereof looking-from right toleft'oi F gu e and r into clamping relation ignated generally 6, a top clamping .bar, designated generally 1, a pair of corresponding connecting bolts, each designated generally '8, and a ca rn snafu-designated generally 9. i

The bottom clamping bar or clamping element 6 includes an elongated bar having a transversely extending handle H) which is formed integral with and disposed beyond one-end thereof The bar 8, as best seen in Figures 3 and 4, has a substantially flat upper surface or face II and its bottom surface is beveled, as seen at l2, from adjacent one of its longitudinal'edges to its opposite longitudinal edge, said beveled surface l2 extending to adjacent the ends of the bar 6 but terminating in slightly spaced relationship to said ends and tapering toward each of its ends, as best seen in Figurel. The surface II is substantially flat or straight in cross section, as seen in Figure 4, but is upwardly bowed or convex in a direction longitudinally thereof, as seen in Figure 1. The bar 6 is provided adjacent its ends and intermediate of its side edges with openings l3. I s

They upper clamping bar 1 includes an upwardly oifset upwardly bowed intermediate portion 14 and corresponding end portions l5 which are downwardly offset with respect to the intermediate-portion l4 and each of which is provided with an opening [6, said openings l6 being spaced the same distance apartas the openings I3. The underside or bottom surface of the intermediate bar portion 14 is substantially flat in cross section and longitudinally bowed upwardly asseen'atll and the upper surface of said intermediate portion I4 is preferably ridgeshaped in cross section, as seen at l8. The ridgeshaped constructionv of the upper surface .18 diminishes toward the ends of theintermediate portion I4 and where said-upper surface merges with the substantially flat upper surfaces of the end portions l 5, the upper clamping bar 1 is provided at said ends of the upper surface l8 with inserts [9. of .hardenedmetal which are suitably secured tethe -upper clamping bar 7 and which have substantially flat upper surfaces, for a purpose which will hereinafter become apparent.

Each clamping bolt 8 includes a head 20 having a bore extending therethrough transversely of the bolt 8 so that each bolt head 20 forms a bearing. Each bolt 8 also includes a shank portion 21 which extends from the bolt head 28 and which is sized to reciprocally engage one of the openings IE and which terminates in a restricted terminal portion 22 which is sized to fit into one of the openings l3. Each shank portion or terminal 22 has a threaded outer end portion 23 to receive a nut 24, and a washer 25 is preferably supported on each shank portion 22 by its nut 24, as seen in Figure 1.

The am .Ish'aift 9, is .providedfwith a pair of corresponding cams 26 which are preferably formed 4 5, the hand employed to hold the shoe may then be utilized to insert the beveled end of the half sole 31 into the clamp 5 so that it will be disposed with its beveled edge abutting the beveled edge 5 of the shank 36 and the surface opposite said beveled edge disposed beneath the yieldable block 33. Assuming that the beveled edges of the shank 36 and half sole 3?, as indicated by the lines 39.

.have beenspreviously coated vwith a. cement or 0, other..bondingfmediummfter the-half: sole 3'! has thus been applied, the hand employed for apply- "bolt" heads 23 will be-disposed outwardly of and adjacent the canis 26 so thatsubstantially no cam shaft" 9 'andthe bolts 8-. The shaft end 29 ing the half sole is then employed to turn the handle 30 to rotate the cam shaft 9 in a clockpIJVlSBQdlIGCtlOII as seen in Figure 4. The initial and before the bolts 8 are applied .to thelopenings movement 1 the 9 Shaft will move cams l6 and 13, one end 28 of the cam shaft 9 is posi- 26 to theirpositwns of Flsure 4 caus n the tioned in one of the bolt heads :2fl a'ridithelother I la P a and 1 to be displaced toward one end 29 is disposed to rotatably engagein-theother another. due to the fact that the bolt Shanks 2| bolt head 29.
