CLAMP.

SPECIFICATION forming part of Letters Patent No. 310,195, dated January 6, 1885.

Application filed June fl, 1884. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM H. GoLnING, a citizen of the United States7 residing at Chelsea, 4in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Clamps, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a clamp or press, and the object in view is to provide an instrument, press, clamp, or tool for compressing and holding certain materials in desired positions while certain work is performed thereon, and which at the same time will be capable of presenting said materials in different positions, so that work may be carried on or eiIected at diierent points or different parts of the material.

So far as holding the work is concerned, the tool, implement, or device is a clamp, and, being provided with means for compressing the material clamped, it may also be denominated a press It is capable of use as a compressingclamp in assembling the parts of articles-such as boxes made of wood, metal, or other material-when said parts are to be joined together by means of nails, glue, solder, or other connecting means ordevices; and it is also capable of use in the process of manufacturing tablets or pads of bill-heads,lettenheads,memorandums,blanks, e., and can also be advantageously used in clamping any material to be made into any article which comprises several parts which are to be united, and I therefore do not limit my invention to its use in any particular art, but it comprehends any and all uses of the clamp constructed as hereinafter more particularly described, and embodying the novel features hereinafter specifically claimed.

Referring to the drawings, Figure l is a plan of my clamp open and sustaining work. Fig. 2 is a plan of the same closed and sus` taining work. Fig. 3 is an end elevation.

Like letters indicate like parts in all the gures.

A represents the end casting, which, by means of the horizontal flanges A, perforated, as shown, for the passage of screws or bolts, may be secured upon any suitable bench or table. Each of the standards A is bifurcated, and cach of the bifurcations is arranged ata right angle to the other, and is provided with inwardlyprojecting fianges, A2, on which rest the bottom boards, B,which are held in place by screws passing through the flanges Al into the under surface of each of the bottom boards. A space, C, is left between the lower edges of the bottom boards, and extends from end to end of the foundation or frame, for a purpose hereinafter mentioned. One of the bifurcations of each of the standards is provided with a bearing, D, for the rod D', passing from end to end of the foundation or frame, and forming, in connection with a similar rod, D?, a portion of the clamp proper, the remaining portions of said clamp consisting of two cross bars, E E. Each of the cross-bars is provided with an integrally-projecting arm, F,adapted to come in contact (when the clamp is swung to'an open position) with stops G on the bifurcation of the standard which is provided with the bearing D, the obj ect of the said arm and stop being to maintain the clamp proper in a substantially-horizontal position when open.

At the middle of the crossbars E E is a bearing, E2, one for the clamping-screw II, provided with a crank or handle, H', outside of the arm, and with a rotatably-mounted bearing-block, H2, at the inner end. In the opposite cross-bar is a bearingblock, H3, which may be cast integrally with the arm; or, as shown in this case, provided with the spindle H, mounted in the bearing E2 of the arm, which is also provided with a thumb or set-screw, The spindle HLl is reduced in size to form a shoulder, H, to bear against the inner face of the cross-bar E', so that when the thumb-screw is loosened the spindle of the bearing block II3 may be rotated in the bearing E2. By this construction one or both ofthe bearing-blocks may be rotated.

In the cross-bar E is an adj Listing-screw, I, and upon the standard A is a step, I', against which the end of the adjusting-screw rests. By means of the adjusting-screw I the clamping-frame is raised or lowered, so as to bring the bearing-blocks farther from or nearer to the bottom boards. In this manner the frame is adapted to support work of different sizes transversely at the center thereof and centrally therein.

J J represent following-boards, which in FOO vided with paste.

' edges for binding.

this instance are rectangular and are used to l which are arranged at right angles to each be intercepted between the bearing-blocks and any work held wit-hin the clamp to prevent lnarring the work.

rIhe manner of using the clamp and press is as follows: For instance, in the manufacture of boxes a rectangular block of a size equaling the interior dimensions of the box is iirst laid uponthe bottom boards, B. rIhe end boards of the box are then placed, one at each end of the frame, and the two side boards are placed upon the form, so that these parts shall rest within the bottom of the box-that is, cornerwise-as shown in Figs. 2 and 3, when the clamp-screw H is revolved, forcing the bearing-blocks either against the ends of the box or against the followingboard J, which may be used, if desired, and the parts are rmly bound in their designed relative position, when they may be fastened by any suitable devices. Now, by lifting the frame and turning the work as it is held therein by the pressure of the bearing-blocks, the thumb-screw II5 being raised, the work may be reversed and the frame again dropped, when the remaining sides may be secured to the ends and the work removed. Another instance in using the clamp and press is in binding and otherwise ornamenting cigarboxes, the boxes being` held in the clampingiiig frame with or without the followingboards while successive edges of the same are covered with the binding, previously prorIhe frame is lifted for the successive turning of the box to expose new Another instance of the use ofthe clamp and press is the formation of bill-heads, letter-heads, blanks', &c., into tablets or blocks, in which case the right-angular disposition of the bottom boards again serves the purpose of arranging the separate sheets or blanks in due regularity with each other, and by means of the following-boards and clamping-screw they are compressed and the frame is opened outwardly, as shown in Fig. l,when paste or any suitable cement may be applied to the edges of the sheets, and the binding-sheet, if used, placed on the pasted edges, when the frame is again turned over onto the bottom boards, where the work may be allowed to rest in contact therewith to assure the smooth application of the bindingsheet to the edges ofthe blanks.

In the drawings, Figs. l and 2, K represents the work held between the followingboards, as described.

It is apparent that each ofthe bearing-blocks may be mounted on a tightening-screw, and that an adjusting-screw may be provided in each cross-bar of the clamp.
