To all whom it may concern:

Be it known that I, ISAAC W. HEYSINGEE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have made a certain new anduseful Improvement in a Combined Paper-Weight and Clamping Device, 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 1 is a vertical cross section through a paper Weight and clamp embodying my invention. Fig. 2 is a cross section along the dotted line of Fig. 1. Fig. 8 is a cross section along the dotted line y-fy of Fig. 1. Fig. 4 is a cross section along the dotted line z-z of Fig. 1.

The lettering in all the figures is uniform.

My invention relates to the construction of a paper weight or like device in combination with a spring clamping device adapted to hold or clamp loose sheets of paper or similar objects, and is an improvement upon the device for similar purposes described and claimed in Letters Patent of the United States, No. 172,963, dated February 1, 1876, and granted to Jacob Cain.

My present improvement consists of certain modications designed to render the said devicemore useful in operation, and more effective in constructiomwhich said modifications are as follows. It frequently occurred in the former device that the center post was not perfectly vertical, and in such cases the periphery/of the clamping circle, if fitted to make proper contact with the base in one position, when partly rotated upon its center post, which was constantly liable to occur in use, would open upon one side, the adjustment being uneven of necessity in such cases. To obviate this difculty I make the center post square or angular in cross section, and form the opening of the sliding cover, which embraces the center post, 'of a similar shape, so that the adjustment once made cannot be altered or impaired, as rotation of the cover upon the base is prevented. I'have used pins for this purpose, vertical and outside the line of the center post, but these pins prevent the free entrance of papers up to the middle, and consequently im pair the utility of the device, more especially as the position of the pins cannot 'be seen from the outside, and the principal utility of the article over and above other clips is in is subjected in use, and more especially because the center post must be relatively small in cross section to avoid infringement upon the clamping space for the reception of papers. Hence I form the device of a softer or more brittle white metal, so called, and form the center post of a rod of harder metal, such as wrought iron or steel, which, being roughened at the bottom, and screw-threaded at the upper end, is molded into the base within a suitable collar raised upon the iiat surface of the base plate, which very slightly enlarges the area cut oif from the clamping space, and also permits the use of a much smaller clamping post. The third modification I make is to provide the clamping cover, or cap, the lower margin of which clamps the papers against the base, with a cupshaped annular depression around the center post and sleeve, in its upper portion, and opening upward, which forms a receptacle for pins, pens, or other like objects. This is very desirable when the device is used by tailors or garment cutters, for whose use it is well adapted, as the article, as a whole, serves as a Weight to hold down the goods, and may be moved about at will, while the clamp holds the papers containing the measurements, and the hollow annular dish contains pins which are constantly used to mark the points of measurement or cut. A fourth modification is to make the base and the clamping cover square or angular in cross section, which I am enabled to do, when desired, by reason of rotation of one upon the other being prevented as shown, this shape enabling the papers to be presented squarely at each side.

Referring to the drawings, A is a dat base IOO plate, in the center of which is araised part, A', and into this is inserted the center post, B, which is preferably cast into the base plate while the same is being molded, though it may be screwed in if desired. The center post, B, is roughened at the bottom, B', or it maybe screw threaded to assistin holding it in place in the base, A. This center post is made square or angular in cross section, as shown in Figs. 2, 3, and 4f, and its upper end is screw threaded, as shown at B2, to receive the internally screw-threaded head C, which holds the spring, E, in place, and upon which the thumb of the operator rests to operate the clamp, the [irst two fingers embracing the expanded neck, D4, beneath the expansion, D6. The clamping cover, D, may be square or circular in its periphery, D2, and a1 its center is provided with a sleeve, D4, having vertical opening, D7, extended through the same from end to end. Near the bottom however this sleeve is internally flanged, the flange having an Opening, DS, Fig. 3, corresponding in shape to the cross section of the center post and fitted to reciprocate thereupon, as shown at D5, Fig. l. This flange, D5, forms the lower seat of the coiled spring, E, which abuts above against the under surface ofthe head, C. The external surface of C is cylindrical to permit the sleeve, D4, to reciprocate thereupon, and is provided with au expanded head, C', to limit the upward motion of said cover, D. The clamping periphery of the cover, D, shown at D2, Fig. l, is formed integral with the sleeve, D4, and when raised by the thumb and lingers compresses the coiled spring, E, and, when the fingers are removed the tension of the spring forces down the cover and closes the clampingjaw, D2, against the baseA, entirely around the periphery. In the upper portion of the cover, surrounding the sleeve, D4, I form an annular depression or cup, D, which forms a receptacle open above. This may be closed by a ring cover if desired, but I prefer to leave it open for use. The bottom of the cup I prefer to form with curved or rounded bottom to permit the contents to be more easily reached by the fingers of the operator. In forming the center post, B, square or angular in cross section, I may cut the screw threaded upper end, B2, down to a circular shoulder, but I prefer to merely cnt the screw threads on the four corners, as shown in Fig. 4, whereby the sameis not weakened, and less metal is required for the head, C2, which thus embraces and screws down upon the spring to a proper tension thereof. I usually make these centerposts of square rods of steel or iron, cut tolength and Screw threaded, making them simple and cheap.

While I show the base and clamping periphery square in cross section, I do not re strict myself -to this shape, asI may use them round, octagonal, or of other forms, but I show them square because by preventing rotation thereof upon the center post, I am enabled to make them square which would not be possible if the cover was free to rotate upon the base, as in that case the corners of one would present to the square sides of the other at random, and without control. In Fig. 8 I show a circular outline in dotted lines to indicate the form of such a periphery when used.

I do not rigidly confine myself to the precise construction shown in the drawings, but modify the same, as would be done by any skilled mechanic, without departing from the scope of my invention, as herein shown, described and claimed.

Having now described my invention, what I claim, and desire to secure by Letters Patent, s
