JOHN I. BERRY, OF WILLIAMSPORT, PENNSYLVANIA, ASSIGNO R TO GEORGE W. KLUMP, OF SAME PLACE.

.METALLIC FASTENER FOR WOOD JOINTS.

SPECIFICATION forming part of Letters Patent No. 412,696, dated October 8, 1889.

Application filed October 10, 1888. Serial No. 287,774. (No model.)

To all whom it may concern.-

Be it known that I, JOHN I. BERRY, a citi zen of the United States, residing at William sport, in the county of Lycoming and State of Pennsylvania, have invented certain new and useful Improvements in Metallic Fasteners for Wood Joints; and I do hereby declare the following to be a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

The invention which forms the subject of this specification, and which will be described presently, relates to a new and useful device for fastening together two adjoining pieces of wood, being particularly valuable when the use of nails or screws is not desirable, either from the unpleasant appearance to the eye of the heads of such nails or screws, or in cases when it is really impossible to make use of iveness, at the same time being very economical and easy of insertion.

In order that others may understand my device, attention is invited to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a perspective view of the preferable form of fastener; Fig. 2, a top elevation of the same; Fig. 3, a top view of the fastener, showing it when in position in two pieces of wood; Fig. 4, a modification in the form of the fastener; Fig. 5, a top elevation showing the connecting end straight instead of curved, as in Figs. 1, 2, 3, and 4.

In all of these figures the same parts are designated by identical letters of reference.

Before beginning the description of the form of my invention the material of the same will first be dealt with. I

I Although I do not wish to be limited to its use, I prefer to make the fasteners out of or dinary thin flat sheet iron or steel out into long strips, varying anywhere from threeeighths to an inch or two in width, and these strips are again out into shorter pieces of the right length for the fastener.

Instead of sheet iron or steel I could make use of tin or sheet-brass; butthese latter materials are not so advantageous as the former a, the straight parallel sides b b, and the turned-in ends 0 c. The curved portiona is not an indispensable element in this form, as it could be substituted by a perfectly-straight portion, as shown in Fig. 5, without affecting in any way the results accomplished by the fastener when in use.

The manner of using such a device as just described is as follows: Suppose it is desired to fasten the two pieces of wood as and y se curely and rigidly together. The two pieces are first placed and held firmly together with the grain of the wood running parallel and in the same direction. The fastener is now placed on these ends edgewise, and with its sides parallel with the grain of the Wood, so as to bridge over onto both, as shown in Fig. 3, and is then driven down into the ends, so that the upper portion of the whole device is flush with the top of both pieces. It is immaterial as to the nature and construction of the driving implement used for this purpose, and I do not wish to be limited to any in particular.

When the fastener is in position as shown in Fig. 3, it will be seen that the piece a: is firmly held by means of the curved portion a, and that the piece y is held by means of the turned-in ends 0 0, so that it would be almoft impossible to separate the two pieces. It might be advisable, though of course not absolutely necessary, to glue the two pieces together first before inserting the fastener; but this means, while possessing some advantages, is open to the objection of being more expensive and laborious.

In Fig. 4 is shown a modification in the form of my fastener. The peculiar feature in this modification is, that the ends or lugs c c are turned outwardly instead of inwardly, as in the other forms. This form might be very conveniently used in some instances where it would be impossible to make use of the pre ferred form of fastener, when the wood would be of a peculiar grain and demanded such.

When I have used the expression horse shoe-shaped to indicate the form of the fastmetal of a general horseshoe shape, with ener, I would have it understood that said exstraight parallel sides and with retaining pression is to convey the idea of the shape ends or lugs c c, and adapted to be driven shown in the drawings, wherein the fastener edgewise, substantially as set forth.

5 is represented as having straight sides par- In testimony whereofI aflix my signature in I 5 allel, or approximately so. presence of two witnesses.

Having now described my invention, what I JOHN I. BERRY. claim, and desire to secure by Letters Patent, WVitnesses: is HARRY H. HILL,
