BOX-STRAP TIGI-I'IENER.

Specification of Letters Patent.

Patented Feb. 22, 1916.

Application filed October 21, 1915. Serial lfTo. 57,124.

Toall whom it may concern.

Be it known that I, CHARLES H. PETER- MANN, a citizen of the United States, anda resident of Natalbany, in the parish, of Tangipahoe and State of Louisiana, have invented a certain new and useful Improvement in Box-Strap Tighteners, of which the following is a specification.

The main object of my invention is to provide a tool of durable but simple and inexpensive construction, by the use of which a box strap or similar device may be readily tightened by overlapping portions thereof.

A further object of my invention is to provide means within the tool for holding a nail or similar fastening device, which is adapted to be driven through the overlapped portions of the strap.

With these and other objects in view which shall become apparent as the description proceeds, my invention resides in the construction, combination and arrangement of parts to be hereinafter described and claimed and illustrated in the accompanying drawings forming a part of this specification, and in which like reference characters indicate like parts.

Figure 1 is a perspective view of a box with my improved tightener in operative position upon a strap. Fig. 2 is a similar view after the tool has been turned to tighten the strap. Fig. 3 is a vertical section on the line 83 of Fig. 2. Fig. 4 is a vertical section of a box strap and box after the strap has been secured in its overlapped or tightened position. Fig. 5 is an enlarged View of the tool.

In the drawing A is a box of standard construction having the fastening straps B. My improved tool for tightening these straps consists of a bar 1, having an end portion 2 cylindrical in cross section, and bent at right angles to the main portion of the bar which is used as a handle. Diametrical slots 3 and 4: at right angles to each other are out in the end of the cylindrical portion 2 as clearly shown in Fig. 5. The slot 3 which lies in substantially the same plane as the handle portion 1 of the tool, is of a length and width adapted to receive a box strap, while the slot 4 is of suflicient width to receive a holding nail 5, and of such a length that the base thereof will be over the center of the box strap which is inserted in the slot 3. By this arrangement the slot 4 forms a convenient gage to insure the nail being driven through the center of the strap.

The operation of my tool is as follows. The strap B which it is desired to tighten, 1s inserted in the slot 3 as shown in Fig. 1. The handle is then grasped and the tool turned over to the position shown in Fig. 2, when the slot 4 will be substantially vertical and the strap will be overlapped as clearly shown in Fig. 3 A nail is then placed in slot 4 atthe base thereof, so that it will be above the center of the box strap, and is driven through the strap and into the box for a slight distance. By a lateral movement thereof, the tool may now be removed from the strap, and the nail driven the remainder of the way into the box as clearly shown in Fig. 4, thereby securely fastening the overlapped portion of the strap to the box and so tightening the strap upon the oox.

It will thus be seen that I have provided a strap tightener of simple construction by the use of which a box strap may be easily and quickly tightened and secured in its tightened position.

1. A strap tightener consisting of a handle bar and an arm at the end thereof and at right angles thereto, the extremity of the said arm being provided with longitudinal diametrical slots lying in planes at right angles to each other, one of the said slots lying in substantially the same plane as the handle bar and being of a width adapted to receive a box strap, and the other slot being adapted to receive a holding nail and of approximately one half the length of the first mentioned slot whereby the base of the second slot will operate as a gage to center the holding nail between the edges of the strap to be secured.

2. Astrap tightener consisting of a handle bar and an arm at the end thereof and at right angles thereto, the extremity of the said arm being provided with means for engaging a box strap in such a manner that a revolution of the same will overlap portions of the strap, the said arm being also adapted to receive a fastening device to be driven through the said overlapped portions.

3. A device of the character specified comprising a bar provided at its extremity with longitudinal diametrical slots lying in planes at right angles to each other, one of the said slots being of a width adapted to receive a box strap, and the other slot being adapted to receive a holding nail and of approximately one half the length of the first mentioned slot whereby the base of the second slot will operate as a gage to center the holding nail between the edges of the strap to be secured.

4. A device of the character specified comprising a bar provided with means for engaging a box strap in such a manner that a Copies of this patent may be obtained for revolution of the same Will overlap portions of the strap, the said arm being also adapted to receive a fastening device to be driven through the said overlapped portions.

5. A device of the character specified comprising a bar having slots in the end thereof at right angles to each other, the said slots being adapted to receive a box strap and a fastening nail respectively as and for the purpose specified.
