POWER-PRESS.-
SPECIFICATION forming part of Letters Patent No. 286,839, dated October 16, 1883,
Application filed May 31,1883. (Np Infidel.)
T aZZ whom it may concern Be it kn own that I, ALANSON H. MERRIMAN, a citizen of the United States, residing at Meriden, in the county of New Haven and State of power-presses for heavy work; and the objects of myimprovements are to locate the drivingshaft at the lower part ofthe press, to connect the slide therewith so that it will be pulled downward, and to so arrange the parts that they may be efficient, durable, convenient to. use, and of simple construction. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1. is a front elevation of my press, partly in vertical section. Fig. 2 is a vertical section thereof on line 00 w of Fig. 1; and Fig. 3 is a partial vertical section, partly in elevation, on line y of Fig. 1.
A designates the driving wheel, loosely mounted upon the end of the driving-shaft, in connection with any ordinary clutch mechanism, and treadle B, for operating the same.
C C designate two uprights, to the upper end of which I secure the working-bed D of the press. To the upper side of this bed, and extending upward therefrom, I secure two posts, E E, preferably of a round form, 'so that they may be turned in a lathe. These posts are connected at their upper ends by a tie or crosspiece, F,'and they constitute the ways upon which the slideG reciprocates. Said slide has secured to it two vertical bars, H H, which extend downward through the bed D, one upon each side of the punch or stamp holder a, as shown. The lower ends of these bars H H are secured to a short cross-shaft, b, the ends of which rest in small sliding blocks 0, one of which is shownin vertical section in Fig. 1, and the position of which is indicated in broken lines upon the other side of the machine in both Figs. 1 and 2. These blocks a slide in a groove, (1, formed in the inner face of the uprights 0 C, for guiding the lower ends of the bars H H.
The crank or eccentric h, Fig. 2, of the driving-shaft has one end of the pitman K connected to it, while the other end of said pitman is connected to the toggleL M. The upper member, L, of this toggle is hung upon the under side of the bed D, while the lower member, M, is mounted upon the cross shaft b. I'Vhen the pitman K moves forward under the action of the eccentrich, the toggle acts to force the shaft 1) downward, and causes the bars H H to pull the slideG down with it, and the return movement of the pitman lifts the shaft 1) and slide G back again.
For adjusting the slide G, I thread the up: per ends of the bars H H and place nuts a thereon. These nuts extend through the slide G, and have a collar, on, screwed upon their lower ends, to secure them within the slide and at the same time to leave them free to rotate therein. If desired, the upper ends of these nuts may be made of angular form or provided with holes for the application of awrench or rod for turning them; but for the purpose of moving the nuts n upon both bars simultaneously, so as to always keep the slide square with the posts Eand parallel to the bed D, I form teeth upon the periphery of the nuts n of a suitable form for working in connection with a worm. In front of these nuts I place the shaft 0, having. the head 1) for the application of a rod or wrench, and a right and a left hand worm or thread at its respective ends, which engage the teeth of the nuts n. In order to adjust the slide it is only necessary to turn the shaft 0, and both nuts will turn simultaneously and carry the slide up or down, as may be desired, according to which way the shaft is turned.
If desired, instead of providing the shaft 0 with the head 12, by means of which to rotate it, the shaft may be lengthened and a crank or wheel applied to the end of said shaft for that purpose. Other means for adjusting the slide acter of the other features of my improvements. I am aware that a prior patent shows and .may be employed withoutchanging the char- 7 describes a hay-press having two moving plat- 9 located above said working-bed, the drivingshaft having the eccentrich, and located below said working-bed, and suitable mechanism connecting said eccentric and slide and imparting a reciprocating movement to the slide above the bed for every revolution of the drivingshaft, which is below the bed, substantially as described, and for the purpose specified.
2. The combination of the slide G, supported 011 a suitable frame, the bars H H, extending from the slide downward below the workingbed, the cross-shaft Z), fitted-to slide in suitable guides in the framing at the lower end of said bars, and mechanism for operating said shaft and bars, substantially as described, and for the purpose specified.
3. The combination of the frame of the press, having the bed D, the slide G, bars H H,
