FASTENING DEVICE.

SPECIFICATION forming part of Letters Patent No. 764,487, dated July 5, 1904. Application filed October 19,1903 Serial No. 177,602. (No model.)

To It rel/.0712, it may concern:

Be it known that I, PUTNAM Monnrson, a citizen of the United States, and a resident of Chattanooga, in the county of Hamilton and State of Tennessee, have invented a new and Improved Fastening Device, of which the following is a full, clear, and exact description.

The invention relates to knockdown furniturc; and its object is to provide a new and improved device for :lastening two parts or members of furniture, crates, packing-boxes, and other articles together without the use of screws, nails, or similar fastening means, the device being also serviceable as a support for shelves and the like.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification. in which similar characters of reference indicate cor responding parts in all the views.

Figure 1 is a perspective view of the improvement as applied. Fig. 2 is a face view of the blank for forming the connecting-key for the staples. Fig. 3 is a cross-section of the key, and Fig. 4. is a sectional side elevation of the same.

The fastening device consists, essentially, of a key A and receiving members B B, preferably in the form of staples driven into the parts C C to be joined or fastened together, as plainly indicated in Fig. l. The key A is preferably made from a single piece of sheet 'metal cut to form the blank shown in Fig. 2, which blank consists of a body A, adapted to be bent into angular form to lit the inner faces of the parts C C at the corners thereof, and from the said body A depend spaced arms A A for engaging the receiving members B B, the inner edges A" of the said arms A A being tapering, so as to draw the parts U C toward each other on driving the key home.

From the middle of the body A of the blank extend upwardly flaps A A", arranged one alongside the other and adapted to be bent at right angles to the body A after the latter is bent into angular shape as described, so that the [laps become superimposed, and then their ends are bent under or doubled up, so that the bent-up end of one flap engages the other flap, as will be readily understood by reference to Figs. 3 and t.

By the arrangement described the flaps A A" securely interlock with each other and produce a horizontally-disposed head for driving the key home in a downward direction, so by the blow of a hammer, or for disengaging the key from the receiving members 1) and B on striking the head underneath in an upward direction by a hammer or other tool.

The head of the key is very strong and durable, as it is formed by the interlocked superimposed flaps A A", extending integrally and at right angles from the angular body of the key, so that the said head can be used asa support for shelves and the like.

It is understood that the staples B and B are driven into the parts 0 and C in alinement with each other and properly spaced from the joint of the parts, so that when the key-arms A A are inserted in the staples and the key is driven home then the beveled inner edges A" act at the inner end of the staples so as to draw the parts C and C lirmly together, as previously mentioned.

The fastening device described takes up comparatively little room and serves to securely unite the parts and strengthen the same, especially as the angular body A and the arms A A lit against the faces of the parts C and C.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent- 1. A blank fora fastening device, formed from a single piece of sheet material and comprising a body having depending spaced arms with their inner edges tapering,and upwardlyextending flaps.

9.. A fastening device comprising receiving memberson the parts to be fastened together, and a key having a head and two arms standing at angles one to the other and adapted to engage the said receiving members, as set forth.

3. A fastening device comprising receiving members on the parts to be fastened together, and a key having a head and arms, said arms standing at right angles one to the other and adapted to engage the said receiving members, the said arms having tapering inner edges, as set forth.

4. A fastening device comprising receiving members secured to the parts to be fastened together, a key formed from a single piece of sheet metal and consisting of an angular body, two arms extending from the said body and adapted toengage the said receiving members, and a head formed by flanges extending PUTNAM MORRISON.
