SPECIFICATION forming` part of Letters Patent No. 294,506, dated'v March 4, 1884.

l Application filed January 3, 1884. (No model.) l

ATo L LZZ whom it may concern .l

Be it known that I, JosIAH WV. ROGERS, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Beating-ut Machines; andI do hereby declare that the same are fully described in the following specification and illustrated in the accompanying drawings.

vThis invention relates to improvements in hydraulic beating-out machines for boots and shoes, and it is carried out as follows, reference being had to the accompanying drawings, 'where- Figure 1 represents .a front elevation,l and Fig. 2 represents a central longitudinal section.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

Hydraulic beating-out machines have heretofore been made with a jack attached to and made to move up and down with the hydraulic plunger, combined with a stationary head, to the under side of which the stationary soleformer was secured. In my present invention the jack is made to move by and with the hydraulic plunger, vand as it is moved up and down the head carrying the sole-former in the lupper end ofthe machine is caused to move 'in an opposite direction to the said jack and its plunger, and in this manner the speed of the machine, and consequently its capacity for doing the desired work, is doubled, or very nearly so.- The machine may be varied in its with an annular inwardly-proj ecting offset, b',

to serve as a stop against the flange c of the hydraulic plunger o, as is usual, to prevent the 5o plunger from being forced'out throughthe upper end of cylinder b in case of breakage of i `the upper cross-bar or eitherof its vertical supporting rods or pillars.

To the upper end of plunger c is hinged at `V d the jack-post d, carrying in its upper enda suitable jack, d, in the usual manner.

e is a stationary cross-bar secured in a iirm and substantial manner to the upper ends of the vertical guide rods or pillars e e', the lower under side to correspond with the curvatures of the upper end of the jack d, as shown in Fig. 2. Each post or guide-rod e is surrounded by a pipe or sleeve, g, fitting loosely on said rod and attached in its upper end to the movable head f by means of nuts g g', or in a similar or equivalent manner. To the lower end of each sleeve g is secured a nut or collar, g, and between said collars and the lower fiange, b, of the hydraulic cylinder b is located on each rod e a coiled Spring, lz., capable of automatically raising the head f to its normal position (shown in the drawings) as soon as the hydraulic pressure is relieved.

To the outside of cylinder b are the leverst' z', hinged and supported on the respective fulcra i t, secured to said cylinder b in a suitable manner. 4The inner ends of said levers 'i z' are hinged, respectively, to links t i, the upper ends of which are hinged to the plunger c by means of the respective bolts 13H3, as shown. The outer end of each lever i is made to rest on the top of the collar or nut g, as shown. Thus it will be seen th at when the plunger c, with its jack and jack-post, is moved upward by the hydraulic pressure within the lower part .of cylinder b it causes the head f to move downward by the connecting mechanism, as above described, and both the jack d and former f3 continue to move in opposite directions toward each other until they are brought together with the boot or shoe sole compressed or beaten out between them; and in this man- IOO pacity of the machine for doing its work is materially increased.

K represents an ordinary duplex valve or eut-off, adapted to be operated by means of a lever or handle, la, or equivalent device for turning off and on the liquid under pressure to and from the lower end of the cylinder b.

I desire to state that I do not wish to conline myself to the exact connecting mechanism, as shown and described, between the movable plunger@ and movable head f, as this may be done by other and equivalent means to equal advantage without departing from the essence of my invention. Neither is it essential to have the connections from the movable head f in the form of sleeves f/ g, surrounding` the pillars c e', as solid rods located at the sides of the respective pillars c e may be used to equal advantage.

In the drawings the movable head f is shown as being` operated downward by the hydraulic pressure, and upward by means of coiled springs as soon as the hydraulic pressure is relieved within the cylinder; but this is not essential, as I 'may modify my invention so as to operate the movable head f by the hydraulic pressure in both directions.

IVhat I wish to secure by Letters Patent, and claim, is-

In a hydraulic beatingout machine, the sta tionary cylinder I) and movable plungerl c, carrying the jack d, combined with the movable head j", carrying the former j, and suitable connecting mechanism, substantially as described, between them, for the purpose of causing the said jack and former to move from opposite directions toward each other by the hydraulic pressure, as set forth.

In testimony whereof I have affixed my si gnature in presence of two witnesses.

JOSIAI-I \V. ROGEHQ.
