Specification of Letters Patent.
Patented Sept 8, 1908.
Applicatien filed January 9, 1908. Serial No. $10,024.
T all whom it may concern:
Be it known that l', OSCAR WALLACE, a
States, residing at Elinwood Place, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Clamps, of which the following is a specification.
' inarily adapted do pillars in My invention consists in a clamp,
clamp and draw together the sides of angular structures and it is particularly adapted to clamp the false work of the construction of concrete structures.
' In the accompanying drawing 1 have shown the same adapted to be used with a four-sided pillar and the ,clamping devices applied to each of the four corners thereof, as the preferred form of construction.
' The features of my invention are more fully set forth in the description of the accompanying drawing, forming a part of' this specification, in which:
Figure l is a plan view of a four-sided clamp. 2 is a plan view of one of the corners of said clamp in its clamped position. Fig. 3 is an end elevation of 2. .a perspective view of the clamping wedge.
Wlll first describe the construction.
,1 represents the clamping hers provided near each end thereof with small slots 2.
3 represents ratchet teeth on the outer faces of the bars 1 and adjacent to the slots of said bars.
i represents transverse slidable bars sup-' ported in the slots 2. and provided with the ratchet teeth 5 on the outer faces thereof edjacent to the teeth 3.
6 represents a wedge having in the present case triangular corners which fit and engage the ratchet teeth of the transversely disposed bars. As the wedge is driven the bars are slidable one with the other and clamp the abutting faces of the structure on which they are disposed. I have shown a series of ratchet teeth on each bar member, so that the same set of bars may be used upon different sized columns.
It is obvious that six-sided structuresorother sided structures may he clamped together-by providing a bar memberfor each of the sides to be clamped intersecting the adjacent bar-member and 'rovided with ratchet teeth in the proper ang e to the: correspondingly pribars, provided with the ratche Fig. 4 is preferred form of that, ture, the bars or pins may be fixed together at diagonal corners and the sliding wed connection be applied to the adjacent corners. In some cases an effective clamp will be obtained by applying the clamping mechanism at only one point of the structure.
Vl hile I have shown as the preferred form of construction one of the bars slotted to receive the transverse member, I do not wish angled edge. It will be readily seen say 111 the case of a four-sided struc to be limited to this construction, as any the two transverse teeth, which will. permit one to slide from the other, may be employed in lieu of the V ment, which is a convenient method. of yoking the two transverse bars in slidablo engageinent with each other. I l have shown the triangular wedge as having three full sides, but it will be readily seen that only two of the wedge corners have a functional engagement with the ratchet teeth. The angle of the ratchet teeth and the angle of the wedge will of course correspond in pitch with the angle of the structure to be clamped.
Having 'oescribed my invention, I claim 1. A clamp for a plain sided angular structure, consisting of twoor more bars having ratchet teeth at one end thereof, an intersect ing transverse slidablehar having ratchet teeth at one end thereof opposite the teeth of the bar with which it is in transverse engagement, 2. triangular wedge pin adapted to en slidab'le engagement of gage the oppositely disposed ratchet teethcf substantially. as dothe respective bars, scribed.
2. A clamp for a plaln sided angular struc- .turc, having two or more bars provided with ratchet teeth on their outer faces, an intersecting bar having ratchet teeth opposite the teeth of the barswith which it is in engagement, and a triangular wedge pin adapted to engage the oppositely disposec ratchet teeth of the respective bar meinbers, substantially as described.
3. A- clamp of theclass described, consisting of-two or more bars having ratchet teeth on the outer faces thereof, an intersecting bar slidably supported trensversel'y u on the opposite bar members-provided with ratchet slotted engageteeth adjacent totheteeth of saidmernbers, and a triangular wedge pin adapted to en- 10 lar wedge adapt gage the oppositely disposed ratchet teeth of 5 ture, eonsistmg of two 01' more s otted bars having ratchet teeth adjacent to the slots, 8.
v :transverse intersecting bar having ratchet teeth near the ends thereof and slidable in the slots of the opwosing bars, and a. triangue to engage the oppositely disposed ratchet teeth of the respective bar members, substantially as described. A
5. A clamp for angular structures consisting of two bar members, one slidable with the 15' other, each bar beingtprovided on its outer I". 1 v face with a serles or oppositely disposed seaeee adapted to engage the opposite faces of the opposite ratchet members, substantially as described. I 6. A clamp comprising intersecting bars, a wedge disposed between the extensiens of the bars beyond the intersection, and teeth on the bars engageable with opposite sides of the Wedge, substantially as described.
In testimony whereof, I have hereunto set my hand.
OSCAR WALLACE.
