Specification of Letters Patent.
Patented Aug. 30, 1910.
Application filed December 16, 1909. Serial N o. 533,324.
To all whom it may concern.'
Be it known that I, JOHN SMITH, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Metal- Joiner, of which the following is a full, clear, and exact description.
This invention relates to a device adapted to join the folded-over edges of two sheets of metal by means of a suitable heavy roller.
An object of this invention is to provide a device which will be simple in construction, strong, durable, eflicient and noiseless in its operation, and easily controlled.
A further object of this invention is to provide a traveling member for joining the folded edges of two sheets of metal, the travel whereof will be automatically stopped when said member reaches the end of its stroke.
A still further object of this invention is to provide a metal joiner with a reversible die bed having different sized grooves in each face, whereby different sizes of joints may be made.
These and further objects, together with the construction and combination of parts, will be more fully described hereinafter and particularly set forth in the claims.
Reference is to be had to the accompanying drawings forming a part of this specifica-tion, in which similar characters of reference indicate corresponding parts in all the views, and in whichy Figure 1 is a top plan view; Fig. 2 is a vertical longitudinal section on the line 2 2 of Fig. 1; Fig. 3 is a vertical section on the line 3 3 of Fig. 2; Fig. 4 is an enlarged detail view in vertical section, showing the supporting roller for the driving rack; Fig. 5 is an enlarged vertical transverse section showing the two sheets of metal joined tcgether after having been subjected to the operation of my device, and showing the position of the joint formed and depressed `in the forming groove; and Fig. 6 is a detail edge view of two sheets of metal joined together before being subjected to the operation of my device.
Referring more particularly to the separate parts of the device, 1 indicates a wall or support, to which is secured in any well known manner, as by means of bolts 2, a bed 3, which is preferably in the form of an I-beam set up on edge. The outer end of the bed 3 is provided with a sleeve 4, which is additionally supported by an upright 5. The sleeve 4 extends beyond the outer end of the bed 3, and is adapted to removably receive a die 6, which is preferably in the form of an I-beam having longitudinal grooves 7 on its opposite faces. The outer end of the die 6 is supported on an angle.- iron 8, secured on an upright 9, which is pivotally secured to a base 10. The purpose in having the upright 9 pivotally supported is so that it may be swungdown out of the way, in order to remove the die 6 and reverse it, so as to bring the groove on the bottom face uppermost. The flanges of the die 6 and one of the flanges of the angle bar 8 are perforated so that they may be locked together by means of a pin 11.
At the junction of the bed 3 with the die 6, there is provided a cavity, in which is secured a spring-pressed stop 12, which is normally yieldingly held in a projected position up above the upper surface of the bed 3 and the die 6, so as to form a convenient stop or mark for limiting the position of the work to be acted on. This work generally consists of a couple of sheets of metal 13 and 14 having interlocking folds, as at 15 in Fig. 6. The interlocking sheets of metal 13 and 14 are placed with the fold or seam thereof above the groove 7 in the die 6, and these folds are pressed down into the groove 7, as illustrated in Fig. 5, by means of a very heavy roller 16, which is secured to a shaft 17. The shaft 17 is pivotally secured in followers 18 and 19, which are adapted to slide in grooves 2O in guides 21 and 22 arranged alongside of the die 6 and extending parallel thereto, but at the same height above the said die as the shaft 17.
In order to reciprocate the roller 16,-there is provided a rack bar 23, which is secured to the followers 18 and 19, and engages a pinion 24 on a shaft 25. The shaft 25 is connected through a reversing mechanism 26, which is controlled by a bell crank lever 27, to a power pulley 28. The rear end of the rack bar 23 is provided with an antifriction roller 29, which supports the weight of the rack bar and runs in a channel 30,
which is supported by legs 31. 1n order to automatically reverse the stroke of the rack bar 23, there'is provided a trip 32 on th'e` outer end of the rack bar 23, which is adapted to engage one arm of the bell crank lever 27 on the stroke to the right, and thereby shift the reversing mechanism 26, to draw the roller 16 back toward the left. When the roller 16 and the rack bar 23 reach the end of the inward stroke and approach the wall 1, the trip 32 will strike an upturned end 33 of a rod 34 slidingly mounted on the side of the channel 30. This rod has at its other end an upturned end 35 which will engage the shorter arm of the bell crank lever 27 thereby shifting it so as to operate the reversing mechanism 26. For the purpose of aiding the stopping of the roller 16 at each end of its stroke, there are provided on the bed 3 and the die 6, a pair of chock blocks 36. The guides 21 and 22 are supported at their outer ends in any suitable manner, as by means of guy rods 37, which diverge from the point of connection to the guides 21 and 22, and are secured to any suitable support above.
The operation of the device will be readily understood when taken in connection with the above description. The sheets of metal 13 and 14, which have been previously formed with folded over edges so as to form an interlocking joint or seam 15, are placed in their joined condition, as indicated in Fig. 6, on the top of the die 6, so that the joint 15 overlies the groove 7 on the upper surface of the die. The stop 12 forms a convenient limit by which the operator gages the position of the work on the die. The roller 16 is started in a direction away from the wall 1 by the operator shifting the lever 27. The roller 16 in its travel on the bed 3 and the die 6 first presses the stop 16 downwardly against the tension of its spring, and at the same time grips the sheet of metal, so that there is no movement thereof. The joint 15 is pressed into the groove 7, so that the upper surfaces of both sheets of metal are in the same plane, as clearly illust-rated in Fig. 5. lVhen the roller 16 reaches the end of its stroke, the trip 32 engages the bell crank lever 27, thereby shifting the reversing mechanism 26, and thus reversing the travel of the roller 16. The roller 16 then starts on its inward travel toward the wall 1, and iinally approaches the wall 1 when the trip 32 comes in engagement with the upstanding end 33 of the rod 34, thereby drawing the upstanding end 35 against the side of the bell crank lever 27, shifting it back into its former position, thus operating the reversing mechanism 26, so that the roller 16 is returned to the starting point. The joined sheets of metal may be then removed and a new -set placed on the die, and the operation continued as before.
When it is desired to change the size ort shape of the groove 7, the die 6 is taken out of its supportby knocking down the Lipright 9, and reversed so as to bring the groove 7 on the under surface uppermost.
Having thus described my invention, 1 claim as new and desire to secure by Letters Patent 1. In a device of the class described, the combination with a work support, of a roller adapted to co-act with said work support, a shaft secured to said roller, a plurality of followers rotatably connected with said shaft, guides for said followers, a rack bar connected with said followers, a channel juxtaposed to said rack bar, a supporting roller secured to said rack bar and engaging said channel, and means for operating said rack bar.
