- 2,575,630. 131m Titraxrihn PIERCIN'G TOOL Karlil-i. me k, wmnmamna a Application August 12, la iaseriaiiNo. 119,006 1 claim. (01. lea-1 21011 The invention herein disclosed. is a combination tool for cutting and punching asbestos, slate and other forms of tile.
The general purpose of the invention is to provide a practical form of hand tool which can be used for both trimming and piercing and which while having the leverage necessary for these operations, will be of a convenient size and weight to be carried and used by the operator.
Other special objects of the invention are to provide a tool of the character indicated, of simple, rugged construction and which can be produced at reasonably low cost.
Other desirable objects attained by the invention and the novel features thereof are set forth or will appear in the course of the following specification.
The drawing accompanying and forming part of the specification illustrates a present commercial embodiment of the invention. Actual structure, however, may be modified and changed in various respects, all within the true intent and broad scope of the invention as hereinafter defined and claimed.
' Fig. 1 in the drawing is a broken side elevation of the tool latched in the closed position and with the lower or anvil jaw of the punch shown partly in section;
Fig. 2 is a similar view with the latch released and the tool in opened position;
Fig. 3 is an end view of the tool in the closed position.
Basically the invention comprisesa pair of folded sheet metal hand levers 5 and 6 connected at their ends by a pivot bolt 1 and connected by a This construction aifords ample leverage for ments of the upper jaw H are shown as having downwardly angled extensions 20 pivoted at 2| on a stud extending through the rearward leverage extension ll of the cutter blade 8 and rearward leverage extensions 22 pivotally connected at 23 with side links 24 pivoted over the opposite sides of the lower hand lever 6 by a through stud 25.
The links 24 operate as fulcrum links to close the upper, punch jaw I! over the lower, anvil jaw l5 as the hand levers are closed from the Fig. 2 to the Fig.1 position.
These levers may be equipped with suitable hand grips such as partly shown at 26.
A spring 27 coiled about the lever pivot I and thrusting at opposite ends against the inner portions of the hollow hand levers urges these levers and the connected jaw elements to the open position shown in Fig. 2.
A swinging latch 28 pivoted on the upper pivot stud l2 and making hooked engagement with the lower pivot stud M, provides means for securing the lever handles and jaw members in the closed relation illustrated in Fig. 1.
Both the cutting jaws and the piercing jaws are operable at all times. Either or both may be used at any one time according to the work being accomplished. The cutting jaws have a powerful leverage action suitable for cutting and trimming asbestos tile, slate and the like. Similarly, the punch has powerful leverage enabling it to pierce tile and shingle materials such as mentioned. The parallel side jaws of the cutter and the flat, top portion of the anvil jaw support the material being cut or punched, avoiding cracking and breaking of the more or less brittle materials such as slate and the like.
The mechanism is compact and consists of but relatively few parts considering the double duty character of the tool. The arrangement of parts is such that the shearing mechanism is not in the way when the punch mechanism is being used and, similarly, the punch is not in the way of the cutting operations.
The parts are all of rugged construction and. the tool as a whole can be produced at reasonable cost. Also, by reason of the compact arrangement and cooperation of the parts, the tool is small enough to be carried by the roofer or other operator, taking the place of much bulkier, separate tools heretofore required for tile cutting, trimming and punching operations.
What is claimed is:
A tool for piercing roofing tile and like purposes comprising a pair of hand levers pivotally connected together at their front ends, a pair of leverage members in front or said hand levers, a pivot stud pivotally connecting said members at a point in front of the pivotal connection between the hand levers, said members having leverage extensions projecting rearwardly to the hand levers and pivotally connected with the respective hand levers in back of the pivotal connection between the hand levers, companion piercing jaws in front of the hand levers, one of said piercing jaws being pivotally supported on said pivot stud and having a rearwardly extending portion, a second pivot stud pivotally conmeeting said rearwardly extending portion with the leverage extension of the adjoining member at a point between the first-mentioned pivot stud and the pivotai connection of the leverage eittension of that member with the adjoining hand lever, the other piercing jaw being pivotally fulcrumed on said second pivot stud connecting the of said hand levers.
