JOHN F. WINSLOVV, OF TROY, NEIY YORK.

IMPROVED MACHINE FOR COMPRES-'SING PUDDLE-BALLS.

Specification forming part of Letters Patent No. 34,177, dated January 14, 1862.

To all whom it may concern,.-

Be it known that I, JOHN F. WINSLOW, of

the city of Troy, county of Rensselaer, State of New York, have invented a new and useful Improvement in Machines for Rolling and Compressing Puddle-Balls into Blooms in the Manufacture of Iron, (that two years have not elapsed since the discovery and completion of the sameg) and I do hereby declare the following specification thereof to be full, clear, and exact, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Like letters represent and refer to like parts.

Figure l is a view of the machine, looking downward from the top of the same. Fig. 2 is a horizontal section through the center of the steam-cylinder, showing the piston therein, hereinafter described and set forth. Fig. 3 is a front elevation of the machine.

The nature of my invention consists in upsetting a bloom or blooms of iron at the ends thereof, while being worked by two rollers and cam or eccentric, by means of a bar or hammer moving horizontally by means and use of a steam-cylinder in connection and combination with cam or eccentric wheel, as herein described and set forth.

To enable others skilled in the art to which my invention relates to make and use it, Iwill here describe the construction of the same.

A, Fig. 3, is a cam or eccentric for the purpose of compressing the puddle-ball I into a bloom. B is one of two rollers of like dimensions for the purpose of rolling over the said puddle-ball While being operated upon by the said cam or eccentric. H I-I is frame-work supporting the said cam or eccentric and the machinery operating the same. The said cam or eccentric has a rotot-ary motion, and is constructed and operated as and for the purpose described and set forth in my Letters Patent bearing date the 18th day of December, 1847, to which reference is hereby had concerning the same and the necessary machinery operating it, which is shown in the accompanying drawings.

O is a wheel having' two cams projecting outward horizontally from the periphery of the same, so as to operate against the spur D, Ffig. l, for the purpose of moving back the ram R and the hammer thereto attached after a blow shall have been given against the end of the bloom by the means hereinafter set forth. T is a gag for the purpose of catching and holding back the said ram or hammer, when desired, and is operated by the lever Q. G G, l, are side pieces of the frame containing the guides U II and the crossguide E and the cross-beam W, same figure.

F is a steam-cylinder having but one head X, which is attached to the cylinder in the usual manner. The opposite end of the said cylinder is open and without any head. S, Fig. 2, is a piston constructed with packing, dre., in the usual manner, so that no steam shall escape from the said cylinder. The said piston is attached to the ram R, which bar has a hammer constructed and operated as and for the purpose described and set forth in certain Letters Patent issued to me and John Snider on the 5th day of July, 1848, which I now own, the said John Snider having assigned `to me his entire interest therein. The cross-guide E is firmly connected to the said ram R and is operated with it, thus guiding the said piston S by means of the guides U U, Fig. l. The cross-beamV contains and rmly holds the said cylinder F.

Y is the frame-work, upon which the entire machine rests, and may be of wood or iron.

a is the aperture where the steam is admitted to the cylinder F. A steam-pipe eX- tends from this aperture to the steam chest or boiler, at or near which the steam is admitted to the pipe thus connected. The piston S is driven outward by the steam with great force and power, and having a connection with the hammer by means of the ram R thus and thereby gives a heavy blow against the bloom at the desired time and point, which when done the said hammer` ram, and piston are moved back for another blow by means of one of the said horizontal projecting cams upon the said wheel c, by which the said piston is driven into said cylinder toward the steam-aperture a, through which the steam by which the blow was given is forced back or compressed into the steam chest or boiler, and when the said cam has passed, the said spur D again returns to said cylinder, thus giving another blow, and so the operation continues. The said wheel c may contain as many of such cams as hammerblows required in a given 'time or revolution of the same or any other part of the machine. The steam when once admittedlto the said cylinder F continues its full pressure'against the said piston S. Therefore no valves are required except the stop-valve at or near the steam chest or boiler, as aforesaid. By this arrangement a more forcible blow is given the bloom than by any other means heretofore used.

Hith erto the ram or hammer has been forced against the bloom (thus being rolled) by means of a strong'helical spring surrounding thebar of the hammer, so arranged that its tension would always drive the hammer toward and against the bloom. This spring would easily get out of repair, as well as that part of the machine to which it was immediately connected, which required large expense in repairs and delays in the use of the machine, thus and thereby rendering the same almost entirely useless. By this arrangement these difficulties are entirely overcome, whereby repairs are seldom required and the machine not delayed, but always ready for use.

This machine can be run at less expense and with a greater degree of certainty than any machine heretofore used for the same or similar purpose. It requires no extra steam (of any amount) over and beyond that required to drive the machinery for rolling the puddle-ball into a bloom. The cams upon the wheel c regulate the proper time for the blow to be given the bloom by the hammer attached to the ram R, connected to the said piston S, and also regulates the distance the said piston is driven back into the said cylinder. As the bloom becomes 'hammered or compressed at its ends by means of blows received from said hammer or ram, the farther outward the said piston will be driven by the steam and the more forcible will be the blow then given against the bloom; but in no event can the said piston be driven entirely out of the said cylinder, for it is held in check by means of the said spur D,in connection with the said cam-wheel c. The opposite end of the bloom from that at the said hammer comes in contact with an anvil constructed for that purpose, so as to hold the bloom while receiving a forcible blow from the ram or hammer, as aforesaid, which is referred to in the said Letters Patent of July 5, 1848, as a flange, tc.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

The combination of the steam-cylinder F, the ram or hammerR, the cam-wheel C, with each other, substantially as and for the purpose herein described and set forth.

In testimony whereof I have, on this 13th day of May, 1861, hereunto set my hand.
