DOOR-CLAMP.
Specification of Letters Patent.
Patented Aug. 20, 1907.
Application filed July 12,1906. Serial No. 325,894.
To all whom it may concern:
Be it known that I, DON DIXON, a citizen of the United States, residing at Pikeville, in the county of Pike and State of Kentucky, have invented certain new and useful Improvements in Door-Clamps; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention is an improved clamp for use in holding a door, window sash or the like object in an upright position when the work is to be performed thereon incident to the hanging of the same; and it consists in the construction, combination and arrangement of devices hereinafter described and claimed. 7
In the accompanying drawingsz-Figure 1 is a side elevation of a clamp embodying my improvements; Fig. 2 is a longitudinal sectional view of the same; and Fig. 3 is an elevation, showing the opposite side from that shown in Fig. 1
My improved clamp comprises a stock member 1 and an adjustable member 2 connected thereto for longitudinal movement, so that the length of the clamp may be varied at will. The stock member 1 is provided with a longitudinal guideway 3, in which the member 2 operates. Said member 2 has a rack 4 on its-lower side, and the stock member 1 is provided with anti-friction rollers 5 mounted in recesses above the member 2 to bear against the upper side of said member 2.
A pinion 6 is fast to a shaft 7, which is mounted in hearings in the stock member 1. Said pinion operates in a recess in the stock member and engages the rack of the member 2. A ratchet wheel 8 is secured to the said shaft 7, and a suitable crank, wrench, handle, or the like is, in practice, provided for turning the said shaft. A pivoted pawl 9 engages the ratchet wheel and is provided with a spring 10. The stock member 1 has studs 11 at one end. The member 2 is provided at its opposite end with studs 12. On the side of the stock member 1 opposite that on which the ratchet wheel 8 is placed is a recess 13 here shown as formed between a pair of transversely disposed cleats 14. One of said cleats is provided with a set screw 15.
In the operation of my invention, assuming that the same is to be used for holding a door in an upright position while the door is being fitted and preparatory to its being hung, the clamp is placed in a horizontal position at a suitable height across the doorway, and its member 2 is adjusted so that the stock member 1. bears at its outer end against one of the jambs, while the outer end of the member 2 bears against the opposite jamb, the studs 11 and 12 assisting in securing the clamp in place. One edge of the door is placed in the recess 13 and the set screw 15 is caused to engage the door, so as to clamp the same in place in said recess. Hence, the clamp serves to firmly support the door in an upright position and greatly facilitates the work of fitting and hanging the same.
When the clamp is to be used on a sash, it will be fastened in a similar manner in a window frame and one side of the sash will be secured in its recess.
From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will.be readily understood without requiring a more extended explanation.
Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention, as defined by the appended claims.
Having thus described my invention, what I claim as new and desire to secure by Letters-Patent, is
A clamp of the type described comprising an elongated body or stock having a central longitudinal guideway and a plurality of transverse recesses situated at one side of and communicating with the guideway, a longitudinally movable extension bar arranged in the latter and having ratchet teeth on one of its edges, anti'friction rollers journaled in said recesses to bear on the outer edge of the extension bar, a transverse shaft journaled in hearings in the stock and having a crank handle, a pinion on the shaft and cooperating with the rack teeth for moving the extension bar longitudinally relatively to the stock, means for fixing the shaft against retrograde movement, a pair of spaced transx'ersely disposed cleats projecting laterally from one side face of the bar at :1 point between its ends and forming a door receiving recess. and a clamping screw threaded through one of said cleats.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
DON DIXON.
