tions, and other mechanism wherein a blow has to be struck by a reciprocating body under conditlons known as a whip-stroke, and the ob ect of our present lnvention 1s the construction and arrangement of de' vices whereby this whip action may be attained by the employment of lever devices and parts in connection therewith which are of simple formations.
In the production of mechanism of this character the reciprocating body or head which transmits the blow to the parts that have to be operated upon or struck is desired to have a certain yield so that its recoil or rebound is freely permitted in manner well known. Heretofore to obtain this recoil spring-actuated levers have been mounted upon a body carried by the operating crank with the springs acting thereon in such directions as to cause their lower ends to tend to move apart or from-each other. At these lower ends two links have been pivoted and the reciprocating body has been pivotally mounted upon these two links or parts connected therewith, such links extending somewhat horizontally or at right angles to the direction in which the blow has to be struck, hence by the actions or rebound of the head such links have acted upon the arms of the levers and so have pressed their springs or have extended same as the case may be.
In order that our said invention may be readily understood, we have hereunto appended sheets of drawingsillustrative thereof, to which, by figures and letters, reference is made in the following description Figure l is a front elevation of a power hammer having our improvements applied thereto.
Fig. 2 is a side elevation thereof.
Fig. 3 is a front elevation of the mechanism for operating our sliding head block or hammer. f
Fig. 4: is a sectional plan of line A-B of Fig. 3. Fig. 5 is a sectional front elevation of on improved form of sliding block. Fig. 6 is a perspective view showing the hammer head.
Figs. 3, 4L and 5 are drawn to an enlarged scale as compared with Figs. 1 and 2.
Similar letters and figures of reference indicate like parts throughout the several views.
To attain theobject of our invention, we dispense with the usual links and employ, according to our preferred arrangements, simple levers a, b, which are pivoted at a, 7) respectively to the connecting link 0 carried by the crank stud (Z, this latter being rotated by the crank plate or disk A spring- 9 intervenes betweenthe two levers a, 6, while their ends a are arranged to pass within the cavity h of the sliding block h, this latter carrying the swaging tool or the like as will be well understood. The sliding block it is provided with a slot or slots A through which pass the levers a, 6, their said extremities a 6 being wider than said slotted parts so that their edges take against the surfaces if of the cavity h. This cavity h is of any appropriate shape but preferably somewhat oval as shown in the several figures, and the ends a b of said levers a, b, are pressed outwardly into contact with the surfaces 72. of said cavity 72.
by said spring 9. It will thus be seen that the friction of the parts (1 ,79 against the surfaces h is 'suflicient to enable them to carry the sliding block or head it with them, whereas should anything interfere with the full movement of said head or block it, as compared with the movement that the crank disk 7 might transmit to same, then said parts (1 b slide upon the surfaces k of the cavity k to transmit said variation in the motion between the levers a, b and the head or block it which they'operate. The tension of the spring 9 is or may be adjusted by screws 8, s which pass through the levers a, b and take against the plates 8 8 upon which the ends of the springs 9 press, these screws being held or locked in position by the'nuts s s We may employ antifriction rollers on the ends a 6 of the levers a, b, and in this case the block or head h will be held or supported by the pressure of the lower ends of the levers a, 7) as above described.
The crank disk ,7 is mounted upon the shaft m which is rotated by means of the pulley n and clutch a, which may be arranged in any suitable manner, said clutch being operated by the usual form of bell crank lever n? fulcrumed at n and connected to a foot lever 0 fulcrumed at 0 by means Or the connectin rod 0 while the spring 0 normally tends to withdraw the clutch part or" the pulley out of contact with the clutch 9 Or other means may loe employed to rotate said shaft m.
. The sliding head or block it is provided with guide strips M which slide within groove in a stationary block or guide p carried by or forming part oi the framework C of the machine.
Any appropriate form of swaging tool 9 and block Q may be employed, as these are varied in connection with the particular purposes r which it is required to employ our improved power hammer.
The connecting link 0 may be of the shin ple formation illustrated by Figs. 1 and 2, or it may consist of a downwardly extending rod 0, having a block 0 adjustable thereon, as shown in Fig. 3, by means of which the stroke or position at which the head or block 71, operates may be adjusted.
In Fig. 1 the head or block it is shown in its highest position, while in Fig. 3, it is shown in full lines in its lowest position, and in broken lines approximately in its mid-position; however, it will readily be understood that when our improved hammer is working such head or block h will rise higher than is illustrated by Fig. 1, and will descend lower than is illustrated in full lines by Fig. 3, at which time the ends a 6 of the levers a, b will be moved nearer together thus compressing the spring 5 and it is by means of this yielding movement of said spring and the keeping of said ends @212 in contact with the surfaces if that the e'liective whip stroke of the block or head 7? is effected upon the material under treatment.
It is obvious that we may have varied forms of springs and that we may use more than one of such spring as circumstances render desirable, while further than this we may alter the particular shape or shapes or the levers a and 72, the essential feature:
of our invention being the holding or supporting of the block or head it by the fricion of the parts which bear against its surfaces. t will further be seen that it may be possible to allow the ends of the levers a, b to bear against the exterior surfaces of the block or head h, and still support same by friction however, We prefer the arrangement hereinbefore described.
Such being the nature and object of our invention, what We claim is:--
In a power hammer, a reciprocating block or hammer, grooves formed therein, an opening formed approximately centrally in said block, levers having lateral extensions pressed into engagement with the surfaces surroumling said central opening, a link to which the opposite ends of said levers are pivoted, a single spring intervening between said levers to press their lateral extremitie into engagement with said surfaces surrounding said central opening, means for adjusting the tension ofsaid spring, and means for reciprocating said he r.
