COMBINED PAPER WEIGHT AND CLAMP.

SPECIFICATION forming part of Letters Patent No. 509,900, dated. December 5, 1893. Application filed March 18, 1893. Serial No. 466,597. (No model.)

To all wftom it may concern:

Be it known that I, IsAAc W. HEYSINGER, aA

citizen of the United States, residing at Philadelpl11a,in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in Paper- Holding Clamps, of which the following is a full, clear, and exact description, reference being had to the drawings which accompany and form a part of this specification, in which- Figure l is a longitudinal vertical section through a paper clamping device which embodies my invention. Fig. 2 is a plan view from beneath, showing the recesses of the uppersurface in dotted outline through the glass base. Fig. 3 is a transverse vertical section of Figs. l and 2, through the dotted line -.r, and showing the more forward parts in end vlew, above or through the glass of the base. Fig. 4 is a view similar to that shown in Fig. l, except that the clamping surface of the base is formed at a slope, instead of level, so as to hold the papers in a somewhat elevated position, and the clinching recess of the other iigures is not shown. Fig. 5 is a view similar to that shown in Fig. l, except that a modi tication of the spring is shown, by which the clamping arm is brought down upon the base; and also, in Fig. 5 is shown an external jacket or case in which the glass base may be insertff The lettering in all the figures is uniform.

My invention consists in the construction of a glass paper weight, such, substantially, as are in general use, havinga Weight of from a half pound to one or two pounds, as may be desired, and made of pressed glass, to the upper surface of which is secured, by a suitable bearing, a vibrating clamping arm, the forward end of which is adapted to be compressed against the. upper surface of said glass paper weight, and a clamping spring adapted to operate against said clamping arm and habitually compress the said arm against.A

the said glass paper Weight, until temporarily released by pressure upon the thumb level' at the rear end of said clamping arm, and in rear of the bearing thereof,or by other means of raising the said arm, if desired. It is obvious that any such construction of the glass paper-Weight as is employed in the bases of ordinary paper clips or clamps would be inadmissible, as the fragile nature of the material used, pressed glass, would permit breakage under the slightest rough usage. Hence the glass base must be so molded as to retain its greatest solidity and strength, so that the latter are not materially impaired by the modifications necessary to adapt to it the clamping arm and its attachments.

Myinvention alsoincludesaconcave clinching recess formed in the body of the glass base, and a clincher guiding opening, or its equivalent, in the free end of the clamping or guide arm, so that the article is adapted to form a clinching base for metallic staples as is shown in my Letters Patent No. 226,402, dated April 13, 1880, wherein is clearly shown one of the staple holding and driving tools, andaclinching base and clamping arm adapted thereto. In my present invention, as stated, I form this clinching recess, in which the legs or points of the metallic staples are bent inward and clinched, during the process of driving them through the papers held in place by the clamping arm, by a groove embedded or sunken in the top surface of the glass paper weight which `'constitutes the base of my present device, or

in'- other words I make and use a concave clinching groove or recess of glass or other vitreous material in combination with a staple driving tool and means for guiding the latter in opposition thereto. The advantages of glass are the greater smoothness of surface, and rigidity, together with lack of affinity between the points of the metallic staple legs and the glass surface, so that they are clinched much more readily, and the concave surfaces of the grooves are not dug up or dented by the points of the staples when constantly used, as is the case with metal clinching recesses operating against the points of steel staples. Of course the glass body must be suiiiciently solid and large to bearthe blows of the staple driver, but, this provided for, the clinching recess of glass may be used in any or all forms of staple driving and clinching tools. I prefer to press the clinching groove or recess in the surface of the glass during the formation of the same, by means of a suitably embossed mold, as the compressed surface has a chill or natural surface which it never loses, and which is much more resistant than the glass IOO beneath, if said original surface be cut away, and is also smoother to the end thrust of the staple legs than any tool-cnt groove will be, but, if desired, in special cases the grooves may be cut with a tool, though I do not recommend it.

Referring to the drawings, I show, at A, an oblong glass paper weight, having rounded corners and edges. I secure to the upper surface thereof, as shown, an elongated bar, or arm, B, which extends along the top of the glass paper Weight, A, and rests, at its forward end, B7,againstthesame. The rear end of the arm, B, extends backward, in rear of the support of said arm, and forms a thumblever, B', by depressing which the front end of said YVarm will be raised, as shown; Along said arm, B, on its under side I provide a spring, C, which, as shown in Fig. 5, may itself, form the support of the arm, B, or, as in Figs. l and 4 may act against a lug or stud of the arm B, which has an independent bearing in the top surface of the glass base A.

In Fig. 54 I show a coiled spring, of whichI prefer to use two side by side, and which are secured to a wooden plug, F., driven or cemented in the vertical recess, A', the lower ends of the wires, at C2, being bent to prevent their escape. rlhe upper extremityof thecoiled spring, C', I secure to the arm, B, by solder, or preferably by striking down the top surface of B, as shown at B6 (Fig. 5) and inserting the end of the coil therein, or any other means desired may be used for this purpose. I prefer however to use the means of forming the clamp shown in Figs. 1, 2, 3, and 4, as being more accurate and powerful. This is substantially similar to the device shown in my Letters Patent No. 334,016, dated Jannary 12, 1886, and consists of forming the arm, B, with a sunken cup, B2, open from front to rear, but closed at the sides. Across the rear end of the lower surface of said cup or depression, is an enlargement, B5, which is rounded, to form a bearing in the depressed upper surface of the glass base, A, as shown at, A5, Figs. 1 and 3.

The glass base A, is recessed from beneath, as shown at A and A2, Figs. 1 and 2, the recesses extended entirely through the glass base, A. But the rear part of the recess A', and the front part of A2, do not pass entirely through the glass base, but terminate at A, and A7 A8, leaving spring shoulder seats between the clearance iianges, A10 A10. r1he rear spring seat, A6, is a single offset, but the forward spring-seat is divided, so that A7 and AS form two shoulders, the forward one, A8, slightly lower than the rear one, A7. This is to admit the spring, C, as will be shown. The forward margin of the bottom of the cup or depression, B2, is raised into an upwardly presenting cross rib, B4, against which rests the under surface of the spring C.

To put the parts together the arm, B, is laid upon the base, A, in proper position, the ribbed bearing, B5, resting in the groove, A5.

The spring, C, which is a simple fiat strip of tempered steel, say three-eighths of an inch wide and three inches long, and which may be of No. 21 gage, is inserted, from the rear, through the cup or depression, B2, its forward end passing through the latter and extending downward under the forward spring seat or shoulder, A2, Fig. l. The rear end of C thus is enabled to clear the front margin of the rear spring seat, AG. The rear of the spring C is then drawn down by a hook from beneath, or forced down by a tool from above,

and, at the same time the front end of the spring is forced back from the shoulder, A8, by a tool applied from beneath, until it snaps into place in the spring-seat, A7, and the whole is held in place." Then pressure is applled to the thumb-lever, B, B5 acts as a fulcrum, and the rib, B4, acting against the under surface of the spring, C, raises the front end of the clamping arm, B7, to admit the insertion of papers and the like. It will be seen that the only weakening of the solid glass base is by the two vertical holes A and A2, and I make these with rounded corners, so that the clip base is as strong, practically, as though it were a solid construction. Beneath the clincher, B7, the glass base is entirely solid. The forward end of the clamping arm, B,I vertically slot, as shown at B2, and through this slot,which is accurately fitted to match with the clinching recess, A9, I insert a portable staple driving tool, and insert and clinch metallicA staples through any papers placed between the said clamping jaw and said base. The clinching recess, A9, is a simple concave groove which may be transverse or longitudinal, or may be cross-shaped, as shown in my Letters Patent No. 274,941, dated April 3, 1883, the vertical slot in the end of the clamping arm being formed to correspond as is shown and fully described in said Letters Patent.

top surface of the glass base in the manner shown 'in my Letters Patent No. 327,440, dated September 29, 1885, so that the device is adapted to hold papers in a vertical or more or less inclined or upright position.

In Fig. 5 I show the glass paper Weight base surrounded by an external protecting cover or jacket, F, into which the glass base may be cemented or otherwise secured. This jacket may be of leather, wood, metal, or other suitable material, and may surround the whole base, or the clinching portion alone. I prefer, in general however, to use such a protecting jacket, when I use it at all, around the whole base, and it may be made of an ornamental character. The glass surface of the bottom, A,I usually leave exposed, as a glass surface is much preferable for a paper Weight than one of metal, which frequently becomes roughened from oxidation and, when damp, is apt to stain or'discolor the paperupon which it rests. It is for these reasons that paper Weights of glass are in such general use, but the difficulty in forming bearings and attach- In Fig. 4 1 show the device adapted to a raised IIO ments for spring clamps for combining` the said glass weight with a paper clip attachment has heretofore restricted their use to simple papel' weights, the usual variation beingcalendars or advertisements cemented to their under surfaces, or the like.

In Fig. l show the cup or depression, B2, which forms a socket open above, provided with a pin-cushion, G, which I clamp or cement into the cup, having a convex surface above, as shown in Fig. 1, in which anumber of pins, G G G', are shown in place. This forms a useful addition to the device, and more particularly when used by tailors, garment-cutters, and the like, who require to use pins in laying out their work, the weight, A, holding the fabric in place, and the clamp, B, holdinga paper containing the measurements required.

I do not in this application rigidly con tine myself to the precise construction set forth, or shown in the drawings,but modify the same, as would be done by any skilled mechanic, to meet special requirements, without departing from the principles and scope of my invention as herein shown, described, and claimed.
