ABRAHAM. KREMIANEHKY, OF CO'URBZEVOIE, FRANCE.
HAMMEBINGJEAGHINE AND THE LEKE.
To all whom it may concern Be it known that T, ABRAHAM KnnirmNsKY, residing at Cour-bevoie, Seine, France, have invented certain new and useful Improve ments in Hammer-ing- /lachines and the like, described in the following specification and illustrated in the accompanying drawings.
This invention refers to that class of metal hamm wing machine wherein the hammer lever is actuated by means of cams fixed to a shaft, the bearings of which can be adjusted in height to vary the force of the blows; the object ofmy invention is provide an improved machine of the specified type.
According to my invention in a hammering machine or the like of the type specified If mount the cam shaft in blocks carried by inclined guides with screw controlling means whereby the blocks and thereby the cam shaft may be raised or lowered relatively to the hammer lever for the purpose of regulating the force of the blow. The motive power necessary to operate this machine is obtained from any suitable source. In factories where no power is employed, the machine can be adapted for hand-working. The arrangement and working of the machine will be perfectly understood from the description which follows and which coincides with the annexed drawing.
Figure 1 is a side elevation. Fig. 2 is a front elevation. Fig. 3 is a profile view of a standard bearing; and Fig. 1 is a section of Fig. 3 through X X.
Like numerals of reference indicate like parts throughout the several views.
The machine consists of the frame 1 which is made throughout of cast-iron or any other suitable metal.
2 and 2 are journal bearings secured to the top of the frame 1 adjacent to the front.
3 is a shaft journaled in the bearings 2 and 2 and extending across the machine.
14L is a metal block secured to the shaft 3 midway between the bearings 2 and 2 and 4 is the hammer lever or bar which extends through a. hole in said block and is rigidly secured therein. 5 is the hammer holder secured to the forward end of the bar 4 having a tapered recess in the under side in which the wooden block or hammer 6 is inserted and held by a screw. The tapered recess in the holder 5 allows of the easy removal of .the wooden block 6.
Specification of Letters Patent.
Application filed February 1 1-, 1913.
Patented llfay 256, 1914..
serial No. 748.375.
7 and '7 are a pair of standards having the base plates 19 secured to the top of the frame 1 adjacent to the back. These standards form a pair of inclined guides at the top of which are secured the caps 18, said caps having threaded holes through which the threaded spindles 16 extend.
17 are screw spindles extending upwardly through centrally arranged threaded orifices in the bases 19 of the standards. Each of the spindles 16 and 17 are provided at their outer ends with suitable hand wheels.
15 are journal blocks slidably arranged in the standards 7 and 7 between the inner ends of the spindles 16 and 17 and adjustably held thereby.
8 is the main shaft journaled in the hearing blocks 15 and extending across the.ma chine.
9 and 9 are cams arranged on the shaft 8, either of which may be moved to a central position on the shaft 8 and secured to rotate therewith and each having projections to engage the top of hammer bar 4.
11 is a spiral spring secured at its lower end to the front of the frame and having its upper end connected to an adjustable turn buckle 12 which is connected to the forwardly extending end of the lever t. On one side of the frame is fixed the belt shifting lever 13.
The shaft may be adjusted up or down by operating the screw spindles 16 and 17 thereby moving the cams closer to or farther from the hammer bar. This arrangement provides a variation in the movement of the hammer bar for when the cams are adjusted low down the projections engage the hammer bar at an earlier period and give it a longer throw and as the shaft 8 is raised the movement of the hammer bar is lessened. The strength of the blow of the hammer varies according to the length of movement consequently the adjustment may be regulated to a nicety.
The operation of my machine is as follows :The main shaft 8 by its rotary movement rotates the particular cam being used which has been fixed in the central position, which cam engages the extremity of the lever and raises the mallet-holder to the re quired height as rendered necessary by the nature of the work to be produced, the height being adjusted by the screw spindles. After passing a projection of the cam, the
strikes on the object to be stamped, which is placed in a basin. The form of the material is caused by the blows of the mallet 6 to adapt itself to that of the basin. The basin,
which may be made from either cast-iron or wood to suit the work in hand rests on a column of cast-iron or wood. The object of having a different number of projections on the several cams is to vary the number of strokes, which will be more frequent with a cam provided with three projections than with a cam having one or two projections. This same machine may also be used in a very practical and economical manner for planishing the objects which have already been stamped. In this case, the mallet holder is replaced by a steel hammer, which may vary in weight and form, and which operates in the same manner and under the same conditions as have been described above. In like manner, the basin of castiron or wood may be replacedby a steel anvil of appropriate form to suit the requirement and nature of the work. Even the column may be replaced to advantage by a fixed support attached to the frame or by independent stands.
What I claim as my invention is I- 1. In a hammering machine, the combination with the frame and a pivotal hammer lever, of a pair of standards having guide ways, journal blocks slidably arranged in said guide ways, a shaft journaled in said blocks, a cam secured to said shaft and adapted to engage said lever, and means for adjusting said journal blocks in said guide ways to alter the relative position of the cam and the lever.
2. In a hammering machine, the combination with the frame and a pivotal hammer lever, of a pair of standards having guide ways, journal blocks slidably arranged in said guideways, a shaft journaled in said blocks, a cam secured to said shaft and adapted to engage said lever, and screw spindles carried on said standards and adjustably supporting said journal blocks in the guides.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
