T ALL WHOM Il MAY CONCERNE Be it known that we, EG. FoRDand H. WEIBLE,'of Delphos, in the county of Van Wert, and State of hio, have invented certain new and useful improvements in a device for use in Raising Timbers in Frames; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying. drawings, making part'of this specification, vand to the letters of reference marked thereon, like letters indicating like parts wherever they occur.

To enable others skilled in tho art to construct and use our invention we will proceed to describe it.

Fig'ure 1 is a side View; and

Figure 2, a top plan view, representing the device in operation.

In raising timber frames it is necessaryl to hold the foot of Jthe post or upright timbers of theframe in place to prevent them from slipping when -force is applied to raise the opposite end and bring it intoan upright position. This is usually done by a person holding against 'the foot of the post with a crowbar, thus necessitating a person at cach post; and frequently the bar slips, allowing the p'ost to slip out of positiom'and thereby .producing serious accidents.

Our. invention consists of an adjustable, jointed, metal clamp, to be attached to the post and the timber on which it rests, and thus hold the foot of the post while being raised.

Our clamp consists of -two bars, C, having their outer ends curved downward, and provided with points e, projecting inward, as represented in g. 2. These bars are connected by bolts n, provided at one endwith a screw-thread and hand-nuts h. This part of the clamp is hinged at its inner end to asimilar frame, consisting of the two bars D, havingsimilar points, e, and connected by bolts n with nuts 7;, like those already described. Any number of spurs or hooks, 6 may be attached to the bars C D and arranged tohok into the sides of the timber A and vthe post B, as shown in fig. l, to give them a rm hold on the timbers. A bolt, a, serves to unite the two parts of the, elamp, and the bars D are arranged to move laterally on this bolt, a, so that they can be adjusted laterally to suit any width of post.

To use the device the bars C are first secured to -the timber A, as represented in the drawingaand the nuts h are screwed up so as to force the points e into the timber and give it a irm hold thereon. In placing the clamp care must be taken to locate it ata distance from the mortise in the timber A, equal to the width of the shoulder between the inner edge of the tenon t and the inside face of, the post B, so as to bring the tenon directly into the mortise when the post is raised to an upright position. The clamp being thns secured to the timber A the bars D are folded over back on the other part and the post laid thereon, when it is also tightened up by mcansdof its nuts L. The clamp being thus secured to both the timber A and post B, the latterl is then raised by any suitable means to an upright position, the clamp serving to hold the foot of the post securely in place andgprevent it from slippingvin' either direction. By the use oi' these clamps a less number of persons are required, and the work is more securely and safely accomplished. l

It is obvious that they may be made of any desired size and strength, and that one will be required at the., foot of each post in a bentf By cutting the screw-thread for a considerable distance on the bolts n, as rep resented, the clamp may be adjusted to any sized timber as required. The bolt a has anextra hand-nut, b, as shown in4 fig. 2, placed inside of thebar C for the purposeof adjusting the bars D to a dierent-sized timber or post, as represented in the drawings, independent from the adjustment of the parts C.

Having thusdescribed our invention, what we claim, is`

The hinged bars .C D, constructed and arranged to operate substantially as anu for the purpose set forth.
