Application July 31, 1953, Serial No. 371,674

1 Claim. (Cl. 140-149) This invention appertains to a new and useful improvement and method for breaking ties which protrude beyond the sides of a set concrete wall. Such terminals have to be broken off before further construction on a building and this is an expensive and laborious job that confronts builders. Many injuries are suifered by workmen who have to break off these ties in large building projects.

The principal object of the present invention is to provide a simple method of breaking off of the terminals without practically any chance of injury to the operator.

These and various other objects and advantages of the invention will become apparent to the reader of the following description:

In the drawings:

Figure 1 is a fragmentary vertical sectional view showing a pair of ties, with the present invention engaged with the terminal of one tie.

Figure 2 is a fragmentary horizontal sectional view of the wall, with the implement in the same position and prior to the upward swinging of the implement.

Figure 3 is a fragmentary vertical sectional view through a concrete wall, showing the implement after it has been swung upwardly and the terminal of the tie bent to a vertical position.

Figure 4 is a fragmentary vertical sectional view through a concrete wall, showing the implement after it has been moved downwardly from the position shown in Figure 3.

Figure 5 is a face elevational view of the concrete wall, showing the implement partly in section and by dotted line showing the extent to which the implement is oscillated in order to break off the tie terminal.

Figure 6 is a fragmentary vertical sectional view through the concrete wall after the tie terminal has been broken ofi and the implement is shown being moved to a free position.

Figure 7 is a perspective view of the implement.

Figure 8 is an enlarged fragmentary vertical sectional view, showing just how the implement is associated with the bent terminal end as represented in Figure 4 of the drawings.

Figure 9 is a section taken on line 99 of Figure 8.

Figure 10 is a section taken on line 10--10 of Figure 8.

Referring to the drawings wherein like numerals designate like parts, it can be seen, that reference character A denotes a concrete wall which has set and has the ice terminal portions 13 of ties C protruding from the opposite faces thereof.

Numeral 12 denotes the present invention and this is employed to break off the terminal portions of the ties.

As shown in Figures 7 and 8, the implement consists of a longated barrel 13, open at its opposite end and provided at one end with a laterally disposed handle 14. This handle may be of wood and have a tie bolt 15 ex tending therethrough and through the adjacent end portion of the barrel 13 as shown in Figure 7 and also in Figure 8. Adjacent the handle 14 the barrel is formed with a short longitudinal slot 16, while the end of the barrel 13 opposite from the end having the handle 14 has a short longitudinal slot 17 extending from the end and this is clearly shown in Figure 7. This implement is a very simple construction as above explained and is intended without any other assistance except manual elfort in breaking 01f the tie terminal.

Firstly, the implement is slipped over a tie terminal B, as is shown in Figure 1 of the drawing, with the handle 14 pointed downwardly.

The implement is now swung upwardly in the direction of the arrow in Figure 1, to the position shown in Figure 3. The tie terminal B is now bent to a vertical position and is located in the barrel 13 in substantially the position shown in Figure 8.

With the barrel 13 lowered on the tie terminal as to the extent shown in Figures 4 and 8, the implement is now in the position to operate.

All that is necessary is to oscillate the implement to the left and right a short distance, as suggested by dotted lines in Figure 5 and the tie terminal will snap 0E. The implement is now free and can be removed from the work, and of course the broken off tie terminal will fall out of the barrel 13.

The slot 16 in the barrel 13 is used for the purpose of cleaning the tie in case it becomes hung, it being apparent that a screwdriver or the like may be inserted therethrough to impinge upon a terminal to thereby dislodge the same.

While the foregoing description sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention what is claimed as new is:

A method of breaking off concrete wall tie terminals consisting of first enclosing a terminal with a tube, next swinging the tube to bend the terminal to substantially right angles to the tie, and finally oscillating said tube and terminal about the axis of said tie whereby to twist off said terminal.
