DRAW CLAMP Filed Oct. 29, 1946 GARDEN,
Maser Patented Jan. 18, 1949 UNITED STATES PATENT OFFICE DRAW CLAMP Albert Garden, Bell, Calif.
Application October 29, 1946, Serial No. 706,428
2 Claims.
My invention relates to a draw clamp to press metal sheets or plates together so that they may be united by welding, rivets or bolts.
An important object of the invention is to provide a clamp of simplified construction which may be applied to or removed from the sheets or plates by hammering upon the same.
In the drawings,
Figure 1 is a plan view of a drawing clamp embodying my invention,
Figure 2 is a side elevation of the same, parts broken away,
Figure 3 is an end elevation of the clamp,
Figure 4 is a transverse section taken on line 4-4 of Figure 1.
The clamp is rigid and is formed of metal, and includes upper and lower jaws 5 and 6, connected at corresponding ends by a thick vertical web I. The jaws 5 and 6 diverge toward their free ends, forming a space 8 which diverges forwardly. The jaws 5 and 6 are provided upon their outer faces with longitudinal stiifening ribs 9, these ribs and the longitudinal edges of the jaws converging toward the web I.
The upper jaw 5 is provided with an elongated opening II], at its transverse center. The lower jaw 6 is provided upon its upper face with ribs I l, which converge toward the web 'I and are in alignment with the lower ribs 9. All parts of the draw clamp are formed integral. The ribs H are beveled and have inner vertical faces l2 and outer inclined faces l3, affording sharp edges at the tops of these ribs.
In use, a desired number of steel or metal plates are assembled in superposed relation, and the draw clamp is applied to the assembled plates, the edges of the plates passing into the space 8. The clamp is then hammered upon the plates, and the clamp will firmly press or clamp the plates together. The upper plate 5 may be arranged above the plates and the plates welded together through the opening ID, or otherwise secured together by bolts or rivets accessible through the opening H1. The sharp edges of the ribs H are forced into the adjacent face of the plate. The clamp is removed by hammering upon the same.
It is to be understood that the form of my invention herewith shown and described is partaken as a preferred example of the same and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.
Having thus described my invention, what I claim is:
1. A clamp for pressing metal sheets together, comprising a pair of jaws arranged in opposed relation with respect to each other, a vertical web connected to said jaws adjacent one end thereof, said jaws diverging outwardly from said web to form a space therebetween for the reception of said sheets therein, and spaced ribs on the inner face of one of said jaws converging toward said web, the faces of said ribs being beveled to provide sharp edges thereon for engagement with the face of said sheet complemental thereto.
2. A clamp for pressing metal sheets together, comprising a pair of jaws arranged in opposed relation with respect to each other, a vertical web connected to said jaws adjacent one end thereof, said jaws diverging outwardly from said web to form a space therebetween for the reception of said sheets therein, spaced ribs on the inner. face of one of said jaws converging toward said web, the faces of said webs being beveled to provide sharp edges thereon for engagement with the face of said sheet complemental thereto, and the other of said jaws having a longitudinally-extending opening arranged intermediate the ribs in said one jaw.
ALBERT CARDEN.
