SLUG TRIMMER.
Application filed June 12, 1923. Serial No. 644,995.
- the invention to enable the user to trim a number of such slugs simultaneously and accurately.
A further object of the invention is to provide means for positioning the slugs automatically with reference to the saw.
Still another object is to provide automatic stopping means to stop the machine when the slug trimming operation 18 completed.
Referring to the accompanying drawings, which are made apart hereof and on which similar reference characters indicate similar parts, t Figure 1 is a front elevation of my device,
Figure'2, a plan, v
Figure 3, an end view taken from the right side in Figure 1, and 1 .7
Figure 4, a detail showing the means for holding the slugs in position for sawlng, and
Figure 5, a sectional detail of a guide shown in Figure 1.
In the drawings reference character 10 mdicates a stand or table on which the machinev is mounted, said table having a top comprising two sections 11 and 12 separated in part by a slot 12 extending from one end to about the middle of the table. Pulleys 13 and 14 are mounted respectively below and above the table and a band saw 15 runs over these pulleys. Above the table is a guard 16 for the band saw having at one side a plate 17 providing access to the interior of the guard. r
The slugs 18 have conical projections 19 providing measure finding dots as fully described in my Patent No. 1,434,308 of October 31, 1922. A bar 20 extends across the table and the slugs are located with their surplus ends which'are to be cut off underneath the bar, the points 19 bearing against the front edge of the bar. The saw is so located with reference to the bar as to go between thetype and the points 19 or directly through such points so as to obliterate them as the surplus ends are cut off. The
- swinging arm 24 is pivotally mounted on the table by means of a pin 25 and is located so as to swing directly above the type carrying ends of the slugs and against the points 19 to force the slugs into proper position with the points resting against the bar 20. This arm is of triangular shape for greater strength and a latch 26 is provided on the table for engagement with a fin 27 near the end of the arm, this latch being pivoted at 26on the bar 20 and serving to hold the arm in place close to the bar 20.
The saw is provided with a guide 28 for its rear. (or non-cutting) edge adjustably mounted on the bar 20 by means of a 'pin and slot connection. A guide 29 for the cutting edge of the saw has a projection 30 extending over the edge and a groove 29 underneath through which the points 19 pass in series, the guide 29 serving to hold the points back against the edge of the bar 20 and to insure that they will be cut off exactly at the right point.
The pulley 13 underneath the table is driven by a motor 31 having a shaft 32 connected by worm gearing to a shaft 33 which in turn is connected by bevel gearing to a screw-threaded shaft 34L. The latter shaft serves to move a clamp block 35 lengthwise of the table by means of a connection including a plunger 36. This plunger is held in place by a yieldable detent 36 and has at its lower end teeth adapted to engage'in the screw thread on the shaft 34 whereby when the plunger is depressedthe shaft will move the clamping block toward the saw. Block 35 may engage the slot 12 in the table by a fin or the like to make it travel in a straight line.
Another clamp block 37 is slidably mounted on a guiding strip 37" rising from the table in line with said slot, the block having a slot 38 to receive the saw whereby the block may extend at both sides past the saw toward the block 35 for proper clamping engagement with slugs located between the blocks. By properly positioning the block 35 any desirable number of slugs may be held between the two clamps and the block 37 will'maintain its relative distance from the block 35 as said block is forced to the left by the rotation of the screw 34 thus pre venting the slugs from toppling over or otherwise becoming disarranged.
In the use of the machine the slugs are set up on edge between the blocks 35 and 37 in such a number as may be desirable, the blocks 37 being at this time close to the saw. Thereupon the block 35 is moved up as close to the other block as possible so as to hold the slugs upright in the position shown in Figure 4. The operation of the screw 34 forces the block 35 and the slugs toward the saw and forces the block 37 away from the saw. The weight and inertia of block 37 are such that the slugs are held securely between the two blocks and this'action may be reenforced whenever desirable by a brake on the block 37 acting on the fin 37 which brake may be of any convenient form that will perform the function.
Automatic stopping means is provided for checking the operation of the machine when all of the slugs between the clamping blocks have been trimmed. This means comprises a switch or circuit breaker in a casing 3:), said switch having an operating handle 40 projecting to the right from the hood 16. As the clamp moves past the saw the upper end of the plunger 36 strikes the upper end of the handle 40 and breaks the circuit after the last slug has been trimmed whereupon the motor stops and the operation of the machine is interrupted until the circuit 18 again closed.
If at any time it should be desired to retain the waste ends of the slugs the hole in the table can be closed by a slide. It is sometimes desirable to out long stock not provided with measure finding dots and for this purpose I provide a rear end guide 41 adjustably held in place by rods 42 passing through guides 43, any suitable means being provided for fixing the guides in adjusted positions, the guides taking the place of projections 19.
It will "be obvious to those skilled in the art that the machine of my invention may be modified in various other respects without departing from the spirit of the invention and therefore I do not limit myself to the specific mechanism shown in the drawings and described in the specification but only as indicated in the appended claims.
