CATCH.

SPEGIFIOATEON forming part of Letters Patent No. 727,462, dated May 5, 1903.

Application filed October 6, 1902. Serial No. 126,051. (No modeLI I To all whom it may concern.-

Be it known that I, EDWARD G. SCHRIEFER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Catches, of which the following is a specification.

Myinvention relates to catches, and has for its object the providing of a catch so constructed as to occupy little transverse space and adapted to have its parts interconnect while the pieces to which the catch is secured are still in separated relation and to draw the pieces together by the movement of the connecting-piece of the catch longitudinally of the catch; and my invention will be readily understood from the following description and claims and from the drawings, in which latter- Figure 1 is afront elevation of my improved device shown in connection with two pieces it is desired to unite, with the connectingpiece thrown back into disengaged position and also shown in engaged position at the beginning of engagement in dotted lines. Fig. 2 is a front elevation of my improved device shown in. connection with two pieces in clamped relation. Fig. 3 is a cross-section of my improved device, taken on the line 00a; of Fig. 2. Fig. 4 is a perspective view of my improved device, and Fig. 5 is a side eleva' tion of the blank forming the plate on which the hook-piece slides.

A and B represent two pieces, such as wood or metal, which it is desired to draw together or hold in connected relation.

1 and 2 are plates whichare adapted to be secured to the pieces A and B, respectively, as by means of screws or nails passing through holes 3. The plates 1 and 2 are preferably of sheet metal of half-moon form when formed up, having adjacent plane meeting edges 4 5. The plate 1 has a rib 6, bent or struck up out of its body and separated at one edge thereof from the body, as shown at 7, forming an edge 8 for the rib, along which a hook-piece 9 may be guided. The edge 8 consists, preferably, of a slightly-inclined part 10, merging into a more acutely inclined or curved part 11, the part 11 forming the beginning of the drawing edge for the hook-piece, so that the hook 12 of the hook-piece may be readily passed above or adjacent to and into line with the raised edge 8 when the pieces A and B are separated for readily finding the raised edge when the pieces are to be connected. The raised rib preferably has one end disconnected from the plate 1, as more clearly shown at 15 in Fig. 4, while its other end remains connected with the plate by the web 16 for strength.

The plate 2 has a rod 21 secured thereto by suitable means, preferably by resting in bearings 22 22, formed by having lips 23 23 of the metal curled above the plate to a form to receive the rod. The hook-piece 9 is also preferably formed up out of sheet metal and has a bearing 24 curled at its end for taking about the rod. The bearing is preferably two-part, having a gap 25, in which a spring 26 takes about the red, one end of the spring takingagainst the hook-piece and the other projecting into a pocket 27, formed in the plate 2, for normally forcing the hook-piece backwardly against the plate 2, as shown in Fig. l and in dotted lines in Fig. 3. The pocket is preferably formed by striking up the raised portion 28 out of the body of the plate 2, leaving a slot 29 between the raised portio'n 28 and body of the plate, the spring end taking through the slot. The spring being confined sidewardly between the two-part bearing of the hook-piece slides on the rod with the hook-piece, and the spring end sliding in the slot 29 at the same time permits the spring to slide with the hook-piece and to act for forcing back the hook-piece irrespective of the position of the latter sidewise on the rod.

My improved construction permits ready assembling of the pieces by passing the rod through the bearings of the plate 2 and the bearing and spring of the hook-piece, the teats 3O 30 holding the parts in place, one of which teats may be formed up prior to assembling, leaving only the one teat to be bent up after assembling for holding the parts together, as indicated in Fig. 4.

My improved device forms a simple and effective means for drawing two parts together and takes up little space transversely whether in connected or disconnected relation, and it draws the pieces together by a movement parallel with the planes of the face of the pieces,

so that the catch may take up little transverse space irrespective ot the closeness of the joint between the pieces and irrespective of the distance to which the hook-piece has been drawn upon the inclined face of the plate 1. For convenience of manipulation I provide the hook-piece with a flange or flanges 31 31. Myimproved construction also avoids the necessity of nicety of fit of the catch on the pieces to be drawn together. Thus the edges t 5 of the plates should normally respectively register with the adjacent edges 32 33 of the pieces A and B when attached to the latter; but there may in practice be considerable variation from this proper normal condition, and the plates may be set back considerably upon the pieces away from the edges 32 33, while still permitting the hookpiece to connect with the contacting edge of the rib of plate 1.

My improved construction further permits two pieces to be connected when at relatively different angles. For instance, the plate 2 may be at right angles to the plate 1, indicated in dotted lines in Fig.

In order to provide sufficient space between the rod and plate 2 to permit the hook-piece to pass between the rod and plate, I strike up the ends of the plate under the bearings 22 22, as shown at 34c 84:, thereby raising the bearings.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. In a catch, the combination of a plate having an inclined face bent or struck up from its body and adapted to' be secured to one of two pieces to be connected, with a hook-piece adapted to be secured to the other of said pieces and slidable substantially parallel with the face of said plate and arranged to engage said inclined face for drawing the two pieces toward one another.

2. In a catch, the combination of a plate having an inclined face bent orstrnck up from its body and adapted to be secured to one of two pieces to be connected, with a hook-piece adapted to be secured to the other of said pieces and slidable substantially parallel with the face of said plate and arranged to engage said inclined face for drawing the two pieces toward one another, and aspring for normally pressing the hook-piece to the side of the piece to which it is attached.

In a catch, the combination of a hookpiecc arranged to be pivoted about an axis substantially parallel with the face of one of two pieces to be connected and swingable at substantially right angles to the face of said piece, with means for permitting the hookpiece to slide sidewise substantially parallel with said axis, and means on the other of said two pieces receiving the hook-piece and acting with the hook-piece to draw the two pieces toward one another.

4:. In a catch, the combination of a hookpiece having, a two'part hearing about an axis substantially parallel with the face of one of two pieces to be connected and swingable at substantially right angles to the face of said piece, a spring between the two parts of the bearing, with means for permitting the hookpiece and spring to slide sidewise substantially parallel with said axis, and means on the other of said pieces rcceivinp the hookpiece and acting with the hook-piece to draw the two pieces toward one another.

5. In a catch, the combination of two pieces of sheet metal, a rod secured to one of the pieces, a hook-piece pivoted about and swingable in a plane at substantially right angles to said axis and slidable ltmgitudinally to said axis, slot in the plate, a spring coiled about the rod and taking into the slot and against the hook-piece and slid-able in the slot, and means on the other piece for receiving the hook-piece and acting therewith to draw the two pieces toward one another.

in a catch, the combination of two sheetmetal plates, a rod, bearings therefor formed out of one of the plates, means at the ends of the bearings for securing the rod therebetween, a hoolepiece pivoted and slidable sidewise on the rod, and an inclined way struck up from the other plate for the hook-piece and acting therewith for drawing the two plates toward one another.

In witness whereof I have signed my name hereto in the presence of two subscribing Witnesses.
