Application filed; August 27, 1917.

To all whom it may concern.-

Beit known that I, RALPH (1. PETER, a citizen of the United States, residing at Estherville, in the county of Emmet and State of Iowa, have invented certain new and useful Improvements in Joist-Anchors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates generally to builders hardware and more particularly to certain new and useful improvements in joist anchors.

The primary object of this invention is to provide an anchor for positively securing the ends of a joist or beam to the wall, the joist or beam and anchor being so connected with each other that should the joist or beam become broken and fall, it will automatically become uncoupled from its anchor so as to prevent the wall from being broken away or otherwise damaged.

Another object of the invention is to improve upon devices of this general class by the provision of an extremely simple, strong, durable self-releasing and inexpensive construction, one which will be efficient and reliable in operation, and well adapted to the purpose for which it is designed.

\Yith these and numerous other objects in view, the invention consists of certain novel features of construction and the combination and arrangement of parts as will be hereinafter described and claimed.

In the accompanying drawings forming a part of the application and wherein the preferred form of invention is shown:

Figure 1 is a side elevation of one end of a joist, showing an anchor constructed in accordance with this invention applied thereto, a portion of said anchor being shown embedded in a wall, the latter being necessarily illustrated partly in section;

F ig. 2 is a side elevation of the joist anchor detached from the joist;

Fig. 3 is a top plan or edge view of the same; and

Fig. 4 is a perspective view illustrating the manner in which the anchor member is constructed.

In the drawings above briefly described corresponding parts through the several Specification of Letters Patent.

Patented Dec. 25, 191 *7.

Serial No. 188,403.

views will: be designated by like reference characters, and reference will be herein made to the various elements by their respective indices. To this end, the letter A designates a brick or other suitable wall to which a joist B is to be anchored. The wall A is provided with a recess C for receiving one end of the joist beam, the lower edge of the latter resting upon the lower side of the recess C as clearly shown in Fig. 1 ofthe drawings.

Bolted or otherwise firmly fastened to one side of the joist beam is a strap or bar 1 preferably of iron. This strap 1 extends longitudinally with respect to the joist or beam and has its outer end terminating at a point adjacent the end of the joist. tending through or otherwise secured to the strap 1 or else formed integrally with the same is a stop pin 2, this pin 9. is disposed close to the outer extremity of the bar 1.

The reference numeral 3 designates the anchor member. This anchor member is 1 formed from a flat strip or plate of suitable material, preferably iron, and is bent along a line midway of its side edge into U-shaped form to provide a suitable channel i into which the strap 1 may be fitted. The sides of the U-shaped anchor member thus formed are pressed together at one of their ends and curved or rolled around the intermediate portion of a rod 5. If desired, the rod 5 may be welded or otherwise more firmly secured to the anchor member. The sides of this anchor member are provided with registering notches 6 adjacent their other ends. These notches 6 are adapted to receive the pin 2 when the strap 1 is disposed in the channel 4.

The anchor member 3 is embedded in the wall A when the latter is being built, the end f said member carrying the channel 4 and notches 6 extending into recess C. The joist B when being set up is inserted in the recess C and the outer end of the strap 1 is fitted into the channel 4. the pin 2 being disposed in the notches 6. This holds the joist to the wall. but should said joist become broken, or should it fall for any reason or other it will become uncoupled from the anchormemher 3 and hence the wall A will not be clamaged as is the case where the joist anchor is rigidly secured to the joist.

From the foregoing description taken in connection with the accompanying drawlngs, the construction, use, and operation of the device will be readily understood.

Other modes of applying the principle of invention may be employed for the mode herein explained, change may therefore be made as respects the mechanism thus disclosed provided the principles of construction set forth in the following claims are employed.

I claim.

1. In a device of the class described, the combination of a strap having a transversely extending stop pin adjacent to one end thereof, and an anchor member comprising a plate bent into U-shape, on a line midway of its side edges to provide it with a channel for receiving said strap therein, the upper edges of the two sides of said member being provided with registering notches to receive said pin, and a rod to be embedded in a wall,

one end of said member being bent around the intermediate portion of said rod to secure the latter to said member.

2. In a device of the class described, the combination of a strap having a transversely extending stop pin adjacent to one end thereof, and an anchor member comprising a plate bent into U shape on a line midway of its side edges to provide it with a channel for receiving said strap therein, the upper edges of the two sides of said member being provided with registering notches to receive said pin, a rod to be embedded in wall, and means for attaching said rod-to said member.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
