ADJUSTABLE BRACKET.
SPECIFICATION forming part of Letters Patent No. 623,517, dated April 25, 1899.
Application filed November 15, 1898. Serial No. 696,547. (No model.)
To (Ll/I whom it may concern:
Be it known that I, JAMES C. CARPENTER, a citizen of the United States, residing at Polkton, in the coun ty of Anson and State of North Carolina, have invented a new and useful Adjustable Bracket, of which the following is a specification.
This invention relates to portable brackets, and is especially designed to be applied to the trestle-work of bridges to provide a support for jacks, but may be applied to any upright post or beam as a support for any desired purpose.
To this end the present invention consists in the combination and arrangement of parts, as hereinafter more fully described, and particularly pointed out in the claims.
In the drawings, Figure 1 is a perspective view of the bracket applied to an upright post or beam. Fig. 2 is a longitudinal sectional View thereof. Fig. 3 is a front elevation thereof. Fig. 4 is a detail perspective view of one of the attaching-arms.
Corresponding parts are denoted by like reference-numerals in all the figures of the drawings.
Referring to the accompanying drawings, 1 designates the bracket proper and comprises an approximately L-shaped body 2 and a brace 3, extending across the angle of the body and attached to the ends thereof. A pair of attaching-arms 4 are connected with the bracket and adapted to embrace the beam or post and support the bracket in position. Each of these arms, as illustrated in Fig. 4, has an elongated eye 5 formed at one end and its other extremity bent into a transverse pointed hook 6. A transverse operating-handle 10 is provided upon the arm intermediate its ends. These arms are attached to the bracket by means of a rod or bolt 7, arranged across the vertex of the angle of the L-shaped body and retained therein by suitable eyes or straps S. The projecting ends of the bolt are threaded and extend at opposite sides of the bracket, forming bearing-lugs, and the attaching-arms are connected thereto by means of their eyes 5 and adjustably secured thereon by suitable nuts 9. The eyes of the arms fit the respective ends of the rod 7 loosely, so as to permit of the arms being swung easily upon the rod.
In the application of the device, as shown in Fig. 1, the upright member 11 of' the bracket is placed against one face of the beam 12 and the arms 4 are operated by means of the handles 10 to engage the respective hooked ends thereof with the opposite face of the beam, the arms extending diagonally upward and across opposite sides of the post. Thus when a wei gh t of-an y character is placed upon the horizontal member 13 of the bracket the hooks will be drawn or forced into the wooden beam and the upright member 11 will be clamped against the beam in a substantial and effective manner. The arms 4:, besides supporting-the bracket, also serve as stops to prevent the bracket from being displaced sidewise from the beam.
The brace 3 is provided with a pair of openings 14, adapted to receive the ends 15 of a loop 16. The ends 15 are secured upon the in ner face of the brace 3 in any preferred manner,but shown in the accompanying drawings as bent to form a stop engaging the inner face of the brace. The body of the loop is disposed upon the outside of the braceand adapted to hang downward out of the way and form a handle, whereby the bracket may be raised to release the hooked arms from the beam 12.
By reason of the rod 7 extending beyond the bracket at opposite sides thereof the arms 4 may be adjusted sidewise, and arms of different lengths may be applied to the same bracket, thus accommodating a single bracket to posts or beams of various sizes.
The elongated eyes 5 permit of the hooked ends of the arms being spread apart upon the bolt '7 as a center to engage the hooks about the opposite edges of the beam.
Besides serving as a support for jacking up portions of a bridge this bracket may be used in the construction of temporary scaffolds and stagings, serving as a support for the horizontal beams, and thus it will be observed that the present invention is applicable in a variety of ways.
Changes in the form, proportion, and minor details of construction and arrangement may be made Without departing from the spirit and scope or sacrificing any of the advantages of the present invention.
Having thus described the invention,wl1at is claimed as new, and desired to be secured by Letters Patent, is-
1. A portable bracket, comprising an approximately L-shaped body, bearing-lugs extending at opposite sides of the vertex of the angle of the body, and a pair of attachingarms mounted upon the respective bearinglugs and capable of a longitudinal adjustment thereon,whereby the bracket may be fitted to posts of different sizes, substantially as shown and described.
2. A portable bracket, comprising an approximately L-shaped body, bearing-lugs extending at opposite sides thereof, and attaching-arms, each arm having an elongated eye, whereby the arms are adapted to be fitted to the respective bearing-lugs, and the free ends of the arms are capable of being spread apart, substantially as and for the purpose set forth.
3. In a portable bracket, the combination with an approximately L-shaped body, of a pair of supporting arms, each arm being loosely connected to the body of the bracket, having a hook at its free end and a handle intermediate its ends, substantially as shown and described.
4. In a portable bracket, the combination with the bracket, having a pair of hooked supporting-arms, ofareleasing-handle connected with the bracket, substantially as shown and described.
5. In a portable bracket, the combination with the bracket having a brace connecting the arms of the bracket, and a pair of hooked supporting-arms, of a loop-shaped releasinghandle connected to the brace, substantially as shown and described.
(3. A portable bracket, comprising an approximately L-shaped body, a rod arranged within the vertex of the angle of the body and projecting transversely at opposite sides thereof, the projecting ends forming bearinglugs, eyes or straps embracing the rod and connecting the same to the body of the bracket, and attaching-arms mounted upon the respective bearing-1n gs, substantially as shown and described.
7. A portable bracket, comprising an approximately L-shaped body, threaded bearing-lugs extending at opposite sides of the body, nuts provided upon the respective lugs, and attaching-arms fitted to the same, the nuts being adapted to longitudinally adjust the arms upon the bearing-lugs, substantially as and for the purpose set forth.
S. In a portable bracket, the combination with an approximately L-shapcd body, of a rod arranged within the Vertex of the angle of the body and projecting transversely at opposite sides thereof, the projecting ends of the rod being threaded and forming bearinglugs, nuts provided upon the threaded ends of the rod, and attaching-arms having elon gated eyes, the arms being mounted upon the respective bearing-lugs, and the nuts being adapted to longitudinally adjust the arms upon the lugs, substantially as shown and described.
In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.
JAMES C. CARPENTER.
