SPECIFICATION forming part of Letters Patent No. 744,555, dated November 17, 1903. Application led August 3, 1903l- SferialNo. 168,043. (No model.)
To all whom` it may concern:
Be it known that I, J oN FRANKLIN JACOBS, a citizen of the United States, and a resident of Burnham, in the county of Milin and State of Pennsylvania, have -made a certain` new and useful Invention in Miter-Clamps; and I declare the following to be a full, clear, and exact description of the same, such `as will enable others skilled in the art to'which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this specification. j A
Figure lis a top plan view of the invention. Fig. 1a is a perspective view of the same. Fig. 2 is a sectional view on the line 2 2 of Fig. 1. Fig. 3. is a sectional lview on the line 3 3 of Fig. 1. Fig. 4 is sectional view on the line Y4 4 of Fig. 1. Fig. 5 is a sectional view on the line 5 5 of Fig. 1.
This invention has relation to miter-clamps ,angle-plate c. Slots 2 and 3 are made through the base parallel t0 said end and side walls.
' The clam p-screws d and e extend through the slots 2 and 3 and also through the iianged end and side clamp-blocks fandf which are adjacent to the end and side walls and are adjustable in directions at right angles to each other.
An oblique slotted arm g is pivoted by its inner end to the base at the point h, which is designed to be within the area of the smallest size frame to be clamped. This arm carries a right-angle corner-bearing 4, this bearing having, besides the radial adjustment through the arm g, a sliding movement in elevation from the base.
said slot and rotary play on its pivot-stem lo. A cam-lever Z, having clamp-screw m, is also provided in connection with the slot of said arm. This'oam-lever is designed to operate inV engagement with the corner bearing and .is connected therewith by means of the slotlink n. A ledge 5 is provided in the angle 7, formed by the Walls b and b'.
In operation the clamp-blocks ff and the corner-bearing4 are adjusted in about proper position to accommodate the work to be clamped, and the mitered parts-of a frame are glued and set together on the seat provided by the iianges 6 of the holding clampblocks ff',=the arm g, and the ledge 5, these bearings forming the seat being of uniform The clamp-blocks are then moved against thecorner portions of the framecontiguous thereto and their screws fixed. Three corners being held by the clamp-blocks and the side and end walls in their angular relation to each other, the pivoted corner-bearing 4 is adjusted against the remaining corner, the cam-lever is turned up against it, and its clamp-screw fixed, thereby locking all the corners of the frame firmlyin position. The' work is then left to dry.
Having described this invention, what I claim, and desire to secure by Letters Patent, 1s
1A miter-clamp consisting of a slotted base, side and end walls,adjustable holdingblocks, a pivoted oblique arm, and an adjustable corner-bearing, substantially as specified. j
2. A miter-clamp consisting of side and end walls, adjustable holding-blocks, anoblique slotted arm, an adjustable pivoted cornerbearing, and means for locking the same, substantially as specified.
, 3. A miter-clamp consisting of a base, side and end walls, adjustable holding-blocks, an adjustable slotted arm, an adjustable pivoted corner-bearing, and means for locking the Whole together, substantially as specified.
4. Amiter-clamp consisting of side and end walls, adjustable holding-clamps, and-an oblique pivoted clamping-arm, substantially as specified.
5. A miter-clamp consisting of a slotted base, side and end Walls, holding-clamps'and IOO 8. In a frame-clamp, the combination with the base, and the side and end clamp-blocks operating at right angles to each other, ofthe radially pivotally and. longitudinally-adjustable oorner-bearing in the angle between the side and end clamp-blocks, substantially as specied.
In testimony whereof I afx my signature in presence of two witnesses.
