FRANKLIN MILLER, OF ONAGA, KANSAS.

DOOR-HOLDER.

Application led November 13, 1909.

To all 'whom fit may concern.'

Be it known that I, FRANKLIN MILLER, a citizen of the United States, residing at Onaga, in the county of Pottawatomie and State of Kansas, have invented certain new and useful Improvements in Door-Holders, of which the following is a specification.

My invention relates to clamps, and more especially to that class of clamps now generally employed for the purpose of holding a door in perpendicular relation to the floor in order that said door may be joined, the edges thereof planed, or for any other similar purpose. Heretofore, more or less difficulty has been encountered in producing devices of this character at a low initial cost, and at the same time providing a clamp which shall be absolutely efficient.

It is an object of my invention, therefore, to overcome these objections, and to provide a clamp which, because of its few and simple parts, is easily and quickly assembled and adjusted.

Another object of my invention is to produce a clamp provided with specifically novel means for mounting the jaws of the device, said means comprising a resilient plate` suitably supported at its ends, the jaws being' carried centrally of this plate.

With the foregoing and other objects in view, my invention consists of such details of construction and combination of parts as will be hereinafter more fully described and specifically pointed out in the claim.

In describing my invention in detail, reterence will be had to the accompanying drawings in which like reference characters designate like or corresponding parts throughout the several views, and in which- Figure l is a view in side elevation of my device, showing a door held therein. Fig. 2 is a top plan view of t-he resilient plate, and Fig. 3 is a vertical sectional view of one of the jaws. Fig. 4 is a section on the line 4 4 of Fig. 2.

In carrying my invention into practice, I provide an elongated resilient plate l, the ends of which are supported above the ioor by blocks 2 and 3 having slots 4 and 5 therein, said slots forming seats for the ends of said plate. These blocks are prevented from slipping by screws A which fasten the plate to the blocks and which project slightly below the latter, the ends A thereof forming floor-engaging spurs.

Specification of Letters Patent.

Patented June 21, 1910.

Serial No. 527,830.

Formed in the plate l and disposed nearer one end than the other, is a longitudinally extending slot 6, while upon the opposite side of the center of the plate and approximately in alinement with the slot is a screwthreaded aperture 7. Jaws 8 and 9 are provided and have bases slightly broader than the resilient plate, their bases being provided with channels 10 and l1 respectively, the sides of said channels being adapted to engage the sides of the plate, whereby the tendency to lateral movement on the part of the jaws is overcome. A thumb-screw l2 passes through the j aw 8 and is in screwthreaded engagement with the aperture 7.

The other jaw 9, has a similar screw l3 which projects through the slot 6 and has a nut 14 upon its end, whereby the screw is tightened and the jaw rendered immovable.

From the foregoing' it is thought the operation olt my invention will be readilyT understood, and its utility fully appreciated. It will be seen that the immovable jaw is first liXed in position, the door then placed upon the plate and disposed adjacent said jaw, and finally the adjustable jaw is mounted uponithe plate and placed against the door, where it will be held by a tightening of the'thumb-screw. Any pressure or weight then applied to the door will cause the resilient plate to sag or bow downwardly, thus forcing the upper edges ot the clamps toward each other and gripping the door more securely.

I desire it to be understood that slight changes in the construction and arrangement of parts within the scope of the claim hereunto appended may be resorted to without deviating from the spirit of my invention.

My invention is also especially useful in holding window sash, and table and counter tops, as well as large boards.

Vhat is claimed is:

A door holder comprising a pair of spaced blocks having alining transversely extending recesses in their Lipper faces, a horizontally disposed resilient plate located with its ends in the recesses of the blocks, screws engaged through the plate and through the blocks, and extending slightly below the under surface of the blocks, said screws having sharpened points for engagement in a surface upon which the blocks are disposed to prevent slipping of the blocks, said plate having a screw threaded opening therein and having a longitudinal slot located in spaced relation to the opening, said slot being at one side of the center of the plate and the opening being at the other side of the center of the plate, two jaws arranged for disposal upon the plate, each of said jaws including a vertically extending face and a horizontally extending face, said horizontally extending faces being of greater width than the plate, and having longitudinally extending -recesses therein, and resultant side flanges, said jaws being disposed upon the plate with the plate in their recesses and with their side tianges against the side edges of the plates, a screw engaged through one of the jaws and in the screw threaded opening of the plate, a screw engaged through the other jaw and through the longitudinal slot of the plate, and a clamping nut engaged with the lower end of the last named screw and resting against the undersurface of the plate.

In testimony whereof I aflixmy signature, in presence of two witnesses.

FRANKLIN MILLER.
