A T TORNEYS FELIX KAHN, OF SAN FRANCISCO, CALIFORNIA ADJUSTABLE SHORE FOR CONCRETE FORMS Application filed July 23, 1928.
My invention relates to the general art of concrete-form construction, and, in particular, to posts or shores for supporting the planking, upon or against which the concrete is poured.
The economical use of lumber in concreteform construction, with regard toits adaptability for re-use, is of prime importance, and has received much attention. Obviously, in
the case of posts or shores, in order to adapt them for use under varied length conditions, they should be capable of linear adjustment.
It is to this end that my invention is directed, its special object being the provision of a shore the novel construction of which enables it to be adjusted lengthwise without the use of jacks, screws, bolts or like paraphernalia, the process or act of adjustment being practically continuous.
With this end in view my invention consists in the novel adustable shore hereinafter fully described by reference to the accompanying drawings, it being understood that changes may be made therein without departing from the spirit of the invention as defined by the claims hereunto appended.
In the drawings Fig. 1 is a perspective view of my adjustable shore.
Fig. 2 is an elevation of the same.
Fig. 3 is across section on the line 3-3 of i Fig. 2.
1 is a foot-plate from which extends a guide of suitable nature here shown in a simple form of diagonally positioned angle members 2, between which the post or shore 3 is fitted for linear adjustment.
Secured exteriorly to the angle members is an encircling strap 4:, one or more in number, here shown as two.
At opposite sides, these straps are bent outwardly to form interiorly grooved lugs 5.
' 6 is a U-shaped stirrup which removably receives the shore, the arms 6 of the stirrup entering and sliding in the grooved lugs 5.
In these stirrup arms are made linear series of wedge seats of suitable nature, here shown as slots 7, which with relation to their respective arms are staggered, as seen in Fig. 2.
Serial No. 294,764.
8 are lifting wedges, adapted to be driven into the slots 7, said wedges bearing upon top of thestrap lugs 5.
Locking wedges 9, one of which is here shown, are adapted for seating in the slots under the strap lugs.
It will now be seen that a shore of any suitable length may be initially fitted in the guide 2 and removably rest in the stirrup 6. It is then capable of linear adjustment by the linear movement of the stirrup 6, due to the driving in of the wedges.
It will also be noted that due to its novel structure, and by the proper use of the wedges 8, the shore can be adjusted at will without the employment of jacks, screws, bolts or the like. The wedges being driven in on the two sides of the shore provide for a relatively staggering arrangement of the slots 7 so that when the wedge on one side is fully engaged, the wedge on the other side can just barely enter the slot. This gives opportunity to continually adjust the shore.
The shore can be permanently locked by driving in wedges such as 9, in directions opposite to the wedges 8, as clearly seen in Fig. 1. By removing the wedges, the shore will relieve the form members and the entire assembly may be dismantled for storing and reuse.
I claim 1. An adjustable shore for concrete forms comprising a post; a guide in which said post is fitted for linear adjustment; outwardly projecting lugs fixed to said guide; a U- shaped stirrup carrying the post the arms of said stirrup being slidable in said lugs, and having wedge-seats; and wedges adapted, in association with said seats and lugs, for linearly adjusting the post.
2. An adjustable shore for concrete forms comprising a post; a guide in which said post is fitted for linear adjustment outwardly projecting lugs fixed to said guide on opposite sides; a U-shaped stirrup in which the post is removably fitted, the arms of said stirrup being slidable in the lugs, and having a linear series of slots staggered relatively to each other and wedges adapted, in association with said slots and lugs, for linearly adjusting the post.
3. An adjustable shore for concrete forms comprising a post; a guide in which said post is fitted for linear adjustment; an encircling strap fixed to said guide and formed on 0 posite sides with outwardly projecting interiorly grooved lugs; a U-shaped stirrup in which the post is removably fitted, said stirrup having arms slidable Within said grooved lugs, said arms having a linear series of slots; and Wedges adapted, in association with said slots and lugs, for linearly adjusting the'post.
4. An adjustable shore for concrete forms comprising a post; a guide in which said post is fitted for linear adjustmen t;.an encircling strap fixed to said guide and formed on opposite sides with outwardly projecting interiorly grooved lugs; a ill-shaped stirrup in which the post is removably fitted, said stirrup having arms slidable within said grooved lugs, said 'arms'having a linear series of slots staggered relatively to each other; and
wedges adapted, in association with said slots and lugs, for linearly adjusting the post.
In testimony whereof I have signed my name to this specification.
FELIX KAHN.
