Letters Patent No. 103,312, dated October 18, 1870, antedated October 1, 18.70.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom ttmcy conceriz- Be it known that I, Pnmnns -E. Ausrm, of New Haven, county of New Havenaud State of Connecticut, have invented a new and ,useful Improvement in Feed for Power-Presses; and I do hereby declare the following to-be a full, clear, and exact description of the same, reference being had to the accompanying drawings and to the letters of reference marked thcre-.
(as grasping the metal and in I ldigure 4, the eccentric 'rolls and slide, in the two positions which they assume when the crank is on its extreme centers, both forward and back.
I Similar letters of reference, when they occur in'tlze separate views, indicate like parts.
My invention relates to an improvement in an intermittent feed for power-presses, and consists in a device for grasping the metal and drawing it forward a given distance under the die, and returning over the said metal to the starting point without altering its position.
I' obtain this result by means of a set of eccentric I cream-rollers, which are held upon a slide, and op.- eratmg in connection with a rod. which first closes the said rolls nponthe metal, and afterward operates the slide.
rice is used.
The particular advantage of my improvement is that by its use I am enabled. to operate upon the heated metal as easily, and with the same accuracy, as can now be done upon cold metal, thus adapting a common power-press to forming hot-pressed nuts as readily and easily as in a machine exclusively for that purpose, thereby doing away with the great expense of that class of machinery.
To enable others skilled in the art to make and use my improvement,- I will proceed to describe the construction and operation of the same.
A is a bed-plate, placed upon the bed-piece'ol' the gresiss, and constructed to tit under or around the I is a slide, which rests in hearings in the bed-plate Upon this slide are placed standards d d, w hich sustain the eccentric rolls N N.
The said eccentric rolls are geared together, and
upon one a crank, J, is fastened.
To the crank J one end of the connecting-rod H is groove, whicl attached, while the other is connected with the driw ing-shatt by means of the disk or crank F.
- The rod H may be made in the form shown in figs. 1, -2;..and 3, in two parts, and held together by a boil; or pin,fast in one portion of the rod, the said bolt or pin working in a slot in-the other part of the'rod, thus' allowing one end of the iod to move a given distance without'imparting motion to the other end.
The object of this is to givelost mot-ion for a certain portion of the revolution, and gain time for the operation of the press. a p
The slide D is furnished with a groove, G, the upper portion of. which is formed with the two sides parallel-with each other.- In the lower portion, one ofthe sideswhrlrgrges at a given angle, thus forming a as shown in fig; 4.
The roller E, upon the disk or crank F, travels in the said groove, and operates't-he slide D-and connecting-rod H thereto attached, when the roller E is brought into the lower portion of the groove G. The slide remains stationary when the said roller is trav 'eling across the wide portion of the groove, and in this way the lost motion is gained.
b b are springs, held in proper supports 0 c, and are placed over the slide 1 and back of-the eccentric rolls. The object of thesesprings is to guide and hold the metal as it is being operatednpon by the rolls.
This completes the construction of my improve ment.
The operation is asfollows:
The metal. to be operated upon is first introduced between the springs 12 b, and passed forward and be tween the eccentric rolls N N, as they stand open, as shown in red, fight. When this is done the machine is set in motion.
The revolution of the driving-shaft O imparts motion, by means of the crank'o'r disk 1!, to the connectiug-rotLH, causing it to advance, which operates the crank J, and revolves the two eccentric rolls N N (they being geared together) until they strike the metal. This prevents a further revolution of the rolls N N; but as the connecting-rod Hcontinues to advance, the rolls N N and the slide I are drawn forward, as shown in black, fig. 4, to the full length of the stroke, together with the metal which is grasped between the said rolls. When in this position, snificient lost motion must be given to allow the press to perform its work.
In, receding, the connecting-rod H first operates upon the crank J and forces it back, thus opening and reieasingthc rolls N N from the metal, and at terward'force-. the rolls and slide I back to their original-'position iiizrendiness for the next operation.
wider at the bottom than at the top,
' .WhileI prefer to employ two eceentric roll N N,
it will be observed that a stationary bed may be employed in place of one of the rolls, and the work clamped between the said stationary bed and eccentrieroll. I therefore wish to be understood aselaimiug such a. stationary, as a. proper equivalent or substitute for one of the rolls N N..
Having thus fully deseribedmy invention,
What I claim as new and useful, and desire to seeure by Letters Patent, is-
The combination of the eeuehtrie rolls N N, crank Jgslide I, ro'd' H, and crank .E. substantially in the manner herein set forth. i
