DOOR-HOLDER.

Specification of Letters Patent.

Patented July 14, 1908.

Application filed December 28, 1906, Serial No. 349,838. Renewed May 23, 1908. Serial No. 434,544.

To all whom it may concern:

Be it known that 1, JOHN W. NIDAY, a citizen of the United States, residing at Unionville, in the county of Putnam and State of Missouri, have invented a new and useful Door-Holder, of which the following is a specification.

This invention relates to door holders such as are adapted to be used for clamping a door in fixed position during the operation of applying the hinges or trimming down the edges thereof.

The objects of the invention are to improve and simplify the construction of such devices; furthermore, to increase their efficiency in operation and to decrease the eX- pense attending their manufacture.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of the following claims without departing from the spirit of the invention or sacrificing any of its advantages.

In the accom anying drawings forming part of this speci cation :Figure 1 is a front elevation of a door holder constructed in accordance with the invention Fig. 2 is a similar view, partly in section; Fig. 3 is a vertical section through one of the jaws; and Fig. 4 is a perspective view showing the inner side ends of the threaded rods separated from each other.

Like reference numerals indicate corresponding parts in the different figures of the drawing.

The reference numerals 1 and 2 indicate a pair of jaws, the opposing faces of which are adapted to be fitted against the sides of a door for holding the same securely in position during the operation of trimming down the edges thereof or applying the hinges preparatory to fitting the door into the door casing. The j aws 1 and 2 preferably are connected with each other in an adjustable manner by means of a link device indicated generally by the reference numeral 3, said link device consisting of a pair of threaded rods 4-5 having a pivotal connection with each other. The

preferred form of pivotal connection between the threaded rods 4 and 5 consists of an approximately wedge-shaped ear 6 adapted to fit into a wedge-shaped slot 7 formed in the end of the rod 4, the ear 6 being formed with a perforation 8 to receive a pin 9 adapted to be passed through the perforations 10 in the bifurcated end of the rod 4. Each of the jaws 1 and 2 is formed with a bore 11 to receive one of the threaded rods of the link device. The bore 11 of each jaw at one point is intersected by a socket 12 extending upward from the lower end of the jaw and adapted to hold securely in position a nut 13 which is of practically the same size as the width of the socket 12 so as to be held stationary therein and thus be incapable of rotation. Each of the rods 4 and 5 of the link device extends through the bore 11 of one of the jaws and is engaged with the nut 13.

It will be obvious from the foregoing description that the pivotally connected threaded rods 4 and 5 constitute the sole connection between the jaws 1 and 2, and that by taking the jaws one in each hand and rotating them in opposite directions, they can be easily and quickly adjusted toward or away from each other until they are the proper distance apart to fit the door. When the jaws have been adjusted so that they are of approximately the proper size to fit a door, said jaws can be separated from each other at their upper ends, this movement being permitted by the pivotal connection of the rods 4 and 5, so that the space between the jaws will be wedged-shaped and can be easily fitted over the edge of t e door so that when the two jaws are fitted flat against the floor, the opposin faces of the jaws will be moved into paralle 'sm with each other, and will thus secure a firm gri upon the door.

The means for anc oring the door holder upon a floor, so as to prevent it from slipping during the operation of trimming a door, preferably consists of a hook or catch 15 having a pointed forward end 16 and an eye 17 at its inner end engaged with an eye 18 connected with the jaw 1. It will be obvious that after the jaws have been properly engaged with the door, the holder can be locked in lposition by hammering the point 16 of the 00k 15 into the floor.

The improved door holder of this invention is strong, simple, durable and inexpensive in construction as well as thoroughly e'lficient in operation.

WVhat is claimed is:

1. A door holder comprising a pair of aws, and a pair of pivotally connected threaded rods constituting the sole connection between said jaws.

2. A door holder comprising a pair of jaws each having a socket provided with a threaded member, and a pair of pivotally connected threaded rods engaging the sockets of said jaws and adjustably crinnecting the same with each other.

8. A door holder comprising a pair of jaws each having a bore intersected by a socket extending upward from the lower end thereof, a nut stationarily mounted in each of said sockets, a pair of pivotally mounted threaded rods, each of said rods extending through the bore in one of said jaws and having a threaded engagement with the nut in the socket of said aw, and an anchoring device connected with one of said jaws.

,7,,.4. A door holder comprising a pair of jaws each having a bore, a socket intersecting said bore and extending upward from the lower end of the jaw, a nut mounted in each of said sockets, a pair of threaded rods,

one of said rods having a wedged-shaped slot in one end and the other of said rods having a wedge-shaped ear to lit saidwedge-shaped slot, a pivot pin extending through the inter fitting ends of said threaded rods, and, a hook pivotally connected with one of said jaws JOHN W. NIDAY.
