SHORE CLAMP.

Application filed October 18, 1928. Serial No. 142,426.

This invention relates to certain novel improvements in shore clamps and has for its principal object the provision of an improved construction of this character which will be highly efiicient in use and economical in manufacture.

Among the several objects of the invention is the provision of a device of this character which will be positive in its operation and perform its duty with an assurance of safety.

A further object of the invention is the provision of a device of this character which can be manually forced into clamping relation with shore supporting bars for holding the bars in the required adjusted position and one which can not be easily thrown from operative position by objects striking thereupon or against.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings and in which:

Figs. 1 to 3 inclusive are detail views of the invention illustrating the same in vari ous applied positions,

F ig. 4 is a sectional detail view of the invention taken substantially on line 4-4 of Fig. 1.

Fig. 5 is a sectional detail view taken substantially online 55 of Fig. 1,

Fig. 6 is a plan view of one of the clamping elements embodied in the invention, and

Fig. 7 is a perspective view of another of the clamping elements embodied in the invention.

In the drawing 10 and 11 indicate two shore supporting bars which are adapted to be clamped in an adjusted position by means of my improved shore clamp generally indicated at 12. My improved shore clamp includes clampingelements 13 and 14. The clamping element 13 is substantially L shaped in plan view and has a bight portion 15 provided with an inner edge 16 forming a plurality of equally spaced apart teeth 17. These teeth 17 have their under surfaces 18 beveled in an inwardly and upwardly direction for reasons hereinafter set forth. The limb portions 19 and 20 of this clamping element have their end portions bent upon themselves to provide hook-shaped elements 21- The clamping element 1 1 has depending portions 22 which provide guiding elements when the clamping element 1 1 is disposed transversely of the clamping element 13, these guiding elements are adapted to embrace the outer edge portions of the limb portions 13 contiguous the hook-shaped ends 21. As shown in Fig. 7 the clamping element 11 has an edge portion 23 which provides a plurality of equally spaced apart teeth These teeth 21- have their top surfaces 25 beveled inwardly and downwardly for reasons hereinafter set forth. The clamping element 1 1 is adapted to be positioned transversely of the clamping element 3 beneath the hook-shaped end portions 21 and when the clamping element 1 1 is in clamping position it is detachably latched from detachment with the clamping element 13 by a suitable latch 26. This latch 26 is pivotally connected to the limb portion 19 and provides an end portion 27 which is substantially U-sha-ped in cross section to embrace adjacent portions of the limb portion 19 of the clamping element 14:.

In applying the clamping device in clamping position the bars 10 and 11 are adjusted in the desired position and after this has been accomplished the clamping element 13 is disposed to embrace the bars 10 and 11 in substantially the position illustrated in Figs. 1 to 3 inclusive. When the clamping element 13 is in this position the clamping element 14 is arranged in its proper position with respect to the limb portions 19 and 20. In these positions it will be noted, Fig. 3, that the teeth 17 and 24; are in position to bite into the adjacent surfaces of the shore supporting bars 10 and 11. The next step in applying my shore clamp is to draw the clamping elements so as to dispose the clamping element- 14: in applied position upon the limb portions 19 and 20, it being pointed out that the hook-shaped end portions 21 serve as a pivot for the clamping element 1 which is drawn into clamping re lation in the following manner.

A suitable tool is provided which includes handle portion 28 and this handle portion 28 has an end portion 29 which is bifurcated as at 30. This bifurcated end portion is adapted to receive the body portion 31 of the clamping element 14-. When the tool is in the applied position shown in Fig. 2 it is manually drawn upwardly so as to pivot the clamping element 14 within the confines of the hook-shape end portions 21. "his pivotal movement draws the clamping element 13 into position to dispose the clamping element 14: flatly upon adjaeentgportiens the limb portions 19 and 20, it being pointed out that the hook.sl1ape end portions 21 function further to prevent CllSPlCtCQlIlQTlll of the clamping element hen the clamping element 14 has been drawn tightly into clamping position it will be noted that the teeth 1'? and 2 l'will bite into adjacent surfaces of the bars '10 and 11 thus preventing relative movement of the shore clamp with respect to the bars 10 and 11. As will be noted in Fig. 1 the bevelled surfaces 18 of the teeth 17 extend in a plane opposite the plane in which the bevelled surfaces 25 of the teethfle extend and thisresul'ts in that fact that if an object should strike upon the clamping element 14; itwill tend to dig the teeth 'furtherin'to the adjacent surfaces of the shore clamp rather than displace the clamping element from clamping position with respect to each other.

VVhen the clamping elements are in clampinjg position the latch i ti is brought into operation and functions to detachably latch the 'ela'mpin elements together.

VV'hile I have illustratedand descrihedthe preferred form of construction for carrying my invention into effect, this is capable of variation and modification, without departing from the spirit of'the invention. I,

neeeeee therefore do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claim.

The invention having; been set forth, what I claim as new and desire to secure by Letters P'ZItGHt is A shore clamp including a clamping element having one edge portion provided-with teeth and oppositely disaosed outwardly extending portions at the ends of said element terminating in downwardly ;protruding portions, and a cooperating clamping element formed substantially U-shapednnd having; an edge portion pm led with teeth'a'nd having portions provi mg a pivot for the first mentioned clamping; eleniei'it, said downwardly protruding portions on said first mentioned clam nng element engaging said second mentioned clamping element adjacent said pivot to limit transverse movement of said first'men't ioned element, said outwardly extending portions:beingadapted tobe disposed on opposite sides of said cooperating;- clamping element, and a locking member 'pivotally mounted on one leg of said U-shapedmember and having a bifurcated portion adapted tobe disposedito loel: sa d clamping elements in clamping posi tion.

In testimony whereof I al'fix my signature JACOB "KAU TZ
