.RUDOLF RossLnR, or LEiPZIe, GERMANY.
CLAMP.
'SPECIFICATION forming part of Letters Patent No. '758,47 6, `1lated;April 26, 1904.
Apiicanon flied July 7, 1903. serial No. 164,596. (No modem To 'c1/ZZ whom it may concern:
Beit known that I, RUDOLF RssLnR, a subject of the Emperor of Germany, residing atV Leipzig, in the Kingdomof Saxony, Grermanv Empire, have invented new and useful Improvements in Clamps, of which the following is a specification.
This invention relates to a clamp or fastening which is to serve for suspendingvfabrics to be dried or for stretchingfabrics in a frame.
The same consists of two jaws connected by means of two non-parallel links,'so that on pressingthe jaws together their forward portions must contact.
In addition to simplicity of construction the clamp has an advantage that when used as a stretching-clamp its closure is automatic, but at the same time when under strain the device can be opened and closed.
This invention is set forth in the following specification and claims, and illustrated in the annexed drawings, in which- Figure l is a side elevation of the clamp opened. Fig. 2 shows the same closed. Figs. 3 and 4 are side elevations of one form of clamp. Fig. 5 shows the clamp applied to a frame.
The clamp4 comprises jaws a and b, united by means of links c and d.. These links are not parallel. In other words,they are arranged at an angle to one another, so that the jaws ca and b in closing position touch one another only at their forward portions. In lthe example shown the links c and d consist of a pair of wires passed through holes in jaws and b and bent over'. The jaw a is provided with suspending means e f and extended to greater length than the gripping-jaw The suspending means may be of any suitable desired kind. In the example shown it consists of twoV wire shanks e and f,'the ends of which of jaw or suitable shape can be suspended from a ring or other suitable suspending device.
The two jaws a and b are formed of suitable material, such as wood or other substance. If the clamp is to close automatically, as for suspending objects or as a tension-clamp, the
gripping-jaw ZJ is provided at its grippingpoint with prongs la. The fabric engaged by the prongs draws the movable jaw b to its engaging or locking position and with increased force as the tension increases. 4
An advantage of this clamp is that when used for tension or for suspending a weighty article said clamp can at any time be lopened or closed without its being necessary to first take off the tension. The clamp is thus adapted for holding fabrics, paper sheets, and the like suspended for drying. It is, however, also adapted to stretch fabrics in a frame, say, for drying, as the stretching of curtains or the like or for projecting illustrations on a stretched surface or screen and the like. In such case the clamps can be applied directly to a rod or part of the frame and the latter expanded by its rods being pulled from one another, or each of the clamps can have a special tension device.
A clamp with tension arrangement is shown,
` for example, in Figs. 3 and 4. The jaw a has a springy suspension device comprising springarms z' and k. The free ends of these springarms can be passed through the fabric and bent, Fig. 3, or they could be inserted into an eyelet Z, Fig. 5. The spring suspension could, however, be of any suitable kind. By means of such spring suspension it is possible to secure a tension at or during the time of hanging up the fabric.
Fig. 5 shows a stretching-frame with both kinds of clamps applied to use. Non-springing clamps, as seen in Figs. l and 2, are applied at one side of the frame and at the other side are shown clamps, as illustrated in Figs. 3 and 4.
An advantage of the clamp is that by simple compression of the movable jaws the clamp is immediately released. A disengagement even of a considerable number of clamps can thus be readily elfected.
What I claim as new, and desire to secure by Letters Patent, is-
l. A suspension clamp comprising two jaws, and a pair of links attached to the said jaws for connecting them together, said links arranged in an angular manner with respect to one another.
2. A suspension-clamp comprising a fixed and a movable jaw, said movable jaw provided IOO with prongs, and a pair of links attached to the said jaws for connecting them together, said links arranged in an angular manner with respect to one another.
3. A suspension-clamp comprising a fixed and a movable jaw, said xed jaw of greater length than said movable jaw, and a pair of links attached to the upper portion of said jaws and adapted to connect the jaws together, said jaws arranged in an angular manner with respect to each other.
. 4. A suspension-clamp comprising a fixed and a movable jaw, said fixed jaw of greater length than said movable jaw, a pair of links attached to the upper portion of said jaws and adapted to connect the jaws together, said jaws arranged in an angular manner with respect to each other, and prongs carried by said movable jaw.l
5. A suspension-clamp comprising a pair of jaws, and a pair of links for connecting said jaws together, said links at their ends extending through the said jaws.
6. A suspension-clamp comprising a fixed and a movable jaw, said fixed jaw of greater length than said movable jaw, and a pair of links extending through the jaws and adapted to connect them together, said links arranged in an angular manner with respect to each other.
7. A suspension-clamp comprising a fixed and a movable jaw, said fixed jaw of greater length than said movable jaw, a pair of links extending through the jaws and adapted to connect them together, said links arranged in an angular manner with respect to each other, and prongs carried by the movable jaw.
8. A suspension-clamp comprising a fixed and a movable jaw, said fixed jaw of greater length than said movable jaw, a pair of links extending through the jaws and adapted to connect them together, said links arranged in an angular manner with respect to each other, and a tension device suitably connected to said elongated jaw.
9. A suspension-clamp comprising a xed and a movable jaw, said fixed jaw of greater length than said movable jaw, a pair of links extending through the jaws and adapted to connect them together, said links arranged in an angular manner with respect to each other, prongs carried by the movable jaw, and a tension device suitably connected to said elongated jaw.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
RUDOLF RSSLER.
