EAVES-TROUGH MACHINE.
SPECIFICATION forming part of Letters Patent No. 449,107, dated March 31, 1891. Application filed September 24, 1889. Serial No. 324,905. (No model.)
To aZZ whom it may concern.-
Be it known that I, WILLIAM A. COLSTEN, a citizen of the United States, residing at Great Bend, in the county of Susquehanna and State of Pennsylvania, haveinven ted certain new and useful Improvements in Eaves- Trough Machines; and I do hereby 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.
My invention relates to that class of eavestrough machines in which the sheet metal is clamped down over a suitable form to facilitate the operation of soldering the sections together.
The object contemplated is to produce a more simple, cheap, and efficient tool than those hitherto in use; and with these ends in view my invention consists in the peculiar features and combinations of parts more fully described hereinafter, and pointed out in the claims.
Referring to the accompanying drawings, Figure 1 represents a perspective view of my invention mounted upon tripods; Fig. 2, an end view of the forming-block, showing the clamp in position; and Fig. 3, a similar View showing the clamp released.
The reference-letter a represents the forming-block, which has a longitudinal recess 11 extending along its under side. This recess has a retaining-plate c, the use of which will appear hereinafter. The ends of the forming-block are provided with removable trunnions d, which fit snugly within sockets e in the block, and are held in place by buttons f. The back of the block is provided with a strip g, upon which the bead g upon the trough it rests when clamped down upon the block, as shown in Figs. 1 and 2.
The clamps consist in a sheet-metal strap 2', hinged at j to an inwardly-extending lip It upon the top of the back Z of the spring m. It will be noticed that this spring portion m is bent downwardly away from the bottom of the block, and its free end m projects a slight distance beyond the lower corner of the block in order to receive and engage the hook at upon the free end of the flexible strap 2'. This hookis provided with a cam-lever 0, which is fulcrumed at 0 to the end of the hook. This cam-lever consists in a handle portion p, provided with a bifurcated head 19, within which is pivoted or fulcrumed the end of the strap 1', so that when the hook n is passed over the end of thespring and the lever 0 pushed down the short head or end 19 of the lever will engage and draw the end of spring against the bottom of the block and lock the two ends of the clamp together, as shown in Fig. 2; or, in other wordsithe lever acts upon the spring in the clamping and releasing operation like an eccentric cam.
A cleat q is located upon the upper side of the spring m and passes over the plate 0 to hold the clamp upon the block when the strap '5 is released by pulling the cam-lever away from the spring.
In applying the clamps the several sections of tin z .2, which have first been provided with a bead g, are placed in position upon the block in the usual well-known manner, and the flexible straps 2' are then drawn down over the tin and their ends locked to the ends of the springs by the cam-levers. When thus held down upon the forming-block, the tin can be readily soldered, after which it can be easily removed by releasing the levers and throwing back the straps.
It is obvious that my invention could be varied in numerous ways, which might suggest themselves to a skilled mechanic. Hence I do not limit myself to the exact construction herein shown.
Having thus described my invention, whatI claim as new, and desire to secure by Letters Patent, is-
1. The combination, in a tool for making eaves-troughs, of a forming-block pivoted to rotate upon standards, a pair of sections adapted to embrace the block, one of said sections consisting of a bar bent to fit the block, a plate upon the under side of the block, a cleat on the bar to engage the plate, and a locking cam-lever, all arranged and adapted to operate as specified.
2. In a tool for making eaves-troughs, the
combination of a forming-block, a pair of hinged sections surrounding; the same, one of these sections being normally held in stationary adjustment upon the block and having its end projecting away from and beyond the edge of the block, and the other being adapted to swing backward away flOl'll the block and provided with a hook to receive the projecting end of the stationary section, and 2t omnlever for engaging said end and looking the IO parts together, in the manner and for the purpose substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
