Application filed July 15, 1902. Serial No. 115,712. (No model.

T ttZZ whom it may concern:

Be it known that I, WALLACE HIRAM CAR- TER, a citizen of the United States, residing at Fig. 2 is a side elevation of the same.

East Milton, in the county of Norfolk and State of Massachusetts, haveinvented certain new and useful Improvements in Gripping- Levers; 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, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to gripping-levers,and has for its object to provide a device of this class which is particularly simple in construction and easy and positive of operation.

A further object of my invention is to provide a lever for gripping hoop-iron, strapiron, or wire for the purpose of stretching or drawing the same tight when used for boxstraps or fencing and the like.

With these objects in view my invention consists in the particular construction and arrangement of my lever.

My invention further consists in arranging a lever whereby the grip and strain are on the the same plane and parallel with the pivotal point of the two sections of the lever.

My invention further consists in certain other novel features and in combination of parts, which will be first fully described, and afterward specifically pointed out in the appended claims.

Referring to the accompanying drawings, Figure l is afront elevation of my invention. Fig. 3 is a detail view of the upper section of the lever. Fig. 4 is a detail view of the lower section. Fig. 5 is a front elevation of the lever in an operative position. Fig.6 is aside elevation of the lower section.

Like numerals of reference indicate the same parts throughout the several figures, in which l is the lever, composed of the upper section 2 and lower section 3. V

at indicates the handle,which is securely bolted in the upper section between the sides 5.

6 indicates metal division-blocks, and 7 is a metal strip which passes between said blocks andbetween the sides 5. 8 indicates the grooves in said sides and metal strip for the reception of the hoop-iron or wire, and 9 indicates two bolt-holes, being in the same plane as the grooves8.

The lower section 3 is composed of the side pieces or extensions 10, and the divisionblock 11 between the two, the whole being securely bolted together.

12 indicates the grooves in the side pieces for the reception of the hoop-iron or wire, and 13 indicates two elongated bolt-holes in the side pieces.

Having thus described the several parts of my invention, its operation is as follows: The lower sectionis inserted between the sides of the upper section, as shown, andthe bolts 14 are passed through the two. The lever is now ready for operation, and as the grooves in both sections are in the same horizontal plane the hoop-iron or wire is passed in. When the handle is moved in the direction it is desired to stretch or pull the hoop-iron or wire, the elongated bolt-holes in the lower Section allow the said section to tilt a trifle, as shown in Fig. 5, thereby carrying the grooves in the upper and lower sections out of line, or rather carrying the plane of the grooves of the lower section obliquely across the plane of the grooves of the upper section,

which causes the hoop-iron or wire to be gripped, and the more force that is exerted on the handle the tighter andharder the hoop-iron or Wire is held in the grooves.

It will be seen that the hoop-iron or Wire while being pulled or stretched assists the bolts 14, taking the strain from them, as the binding of the two sections is on the hoopiron or wire, thereby making it possible to construct the lever much lighter than other devices for the same work. It will also be noticed that although the hoop-iron or wire is gripped tightly the grip is of such a character that the material to be pulled Will not stick in the grooves, but can be taken out of engagement just as soon as the power is off .the handle.

By referring to Fig. 2 it ,will be seen that the hoop-iron or wire enters the groove in the lower section first. that the center of the handle, gripping-line It will be also noticed of groove 8, and center of bottom edge 15 of lower section are in the same vertical plane, thereby preventingthe lever from turning or twisting while in operation.

Having thus specifically described my invention, I wish it to be understood that the lower section may be constructed with three or more pieces or extensions 10, and the upper section may have two or more metal strips 7, so as to increase the number of gripping or binding points. Furthermore, I do not wish to be understood as limiting myself to the exact construction herein set forth, but consider myself clearly entitled to all such changes and modifications in form and construction as fall within the limit and scope of my invention as defined by the following claims. A

What I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a gripping-lever, the combination of two lovers having gripping-slots lying normally in a transverse plane, and pivotal means lyingin the plane of the slots consisting of fixed bolts in one lever and elongated slots in the other through which the bolts pass.

2. In a gripping-lever, the combination of two sections loosely pivoted together, n1eans in said sections for gripping material, the gripping means in said lower section being adapted to lie in a plane obliquely across the plane of the gripping means in the upper section, when the lever is in operation.

3. In a gripping-lever, the combination of two sections, pivoted together, gripping means in said sections which are in the same plane with each other when the lever is at rest, and which are obliquely located when in operation.

4. In a gripping-lever, the combination of an upper section, a lower section secured thereto, said sections being provided with slots normally in alinement for the reception of the material to be gripped, and means connecting the sections and allowing said slots to pass out of alinement by a lateral movemenl.

In testimony whereof I affix my signature in presence of two witnesses.
