STEAM-HAll/iiViE-RS.
Specification forming part of Trotters Patent No. 33,595, dated (li-toller 29, 196i To all whom it Aliz/(ty concer/i.-
Be it known that l, ROBERT Mouiuson, o' the town and county of Newcastle-upon-Tyne, in the Kingdom of Great Britain, have invented a new and useful Improvement in the l'Iammer-Bar for Steam-Hammers; and l do hereby declare that the following` is a full and exact description of the same, ref erencc bcin g had to the accompanyingdrawings, and tothe iigures and lettersof refere nce marked thereon.
My invention is an improvement upon the mode of constructing the ham m cr-bar for such steam-hammers as are described in a patent granted to me in the Kingdom of Great Britain, dated August (i, 1853; and consists in an improved method of guiding the hannner-bar and directing it down upon its work, instead of carrying the framing-standards above the top of the cylinder for the purpose ot' guiding therein the hammer-bar by means of a crosshead formed on the upper end of the latter. I now provide a simple and effective means of preventing the hammer-bar from turning on its axis, to insure an accurate direction of its blows down upon the work by reducing the ent-ire length ot' the upper halt of the hammerbar on one side or on both sides to form flat surfaces, or on all sides to form a square or an oval shape, or wit-h a feather or key let into the said bar, or any other section, to prevent it from turning upon its axis, which, fitting to a correspondingly-shaped stu lling-box in thc top of the cylinder, acts as an effective guide for the hammer-stroke- 'lhisimprovement has reference only to that class ot' my improved hammers which is intended 'for general forging work, those cmployed exclusively for puddlin g purposes and with round faces requiring no such means of preventing a change in the position of the hammer-face.
In order that my said invention may be fully understood, l will now proceed more particularly to describe its construction and opera tion.
Referring to the drawings forming part of this specification, in which the same letters of reference allude to similar parts throughout the several views, lfigure l is a front elevation of my improved steam-hammer, showing one of the modes for preventing the bar from turning upon its axis; Fig. 2, a corresponding elevation ol` the saine at right angles to lfig. l; Fig. 3, a detached elevation of the hammerbar; Fig. 4, a plan of the same, corresponding; Fig. 5, a horizontal section ot' the 'frame and steam-cylinder, with thc hammer-bar in position; Fig. G, transverse section, showing both sides ot' the bar llattened; Fig. 7, transverse section, showing all the sides iattei'led and forming a square.
rlhe steam-cylinder A is bolted between the two frame-pieces b by rows of bolts passing through longitudinal Iianges C in the cylinder and corresponding iianges in each frame-piece, the latter being at their bottom expanded ends bolted down to the foundation-plate l), their upper ends bein g llush with the top level of the cylinder. The working-piston Gis forged upon the hammer-bar ll at its longitudinal center, and provided with a single packingring, conned in a groove turned out of the pistou. Thelower part, a, of the hammer-bar is round, and extends downward through a deep stuting-box, F, cast solid with the cylinder to form its lower end cover. The upper half, ZJ, of the hammer-bar, above the piston G, is longitudinally flattened off ou one side, in the manner best seen in Fig. 5, and, by being con fined in a correspondingly-shaped st-uiiiug box, l, acts as an accurate guide in directing the hammer-face down upon the Work, and the other modes are used in like manner. The hanuuer-bar, besides being longitudinally guided in its movements in the upper and lower standing-boxes, is thus eiectually pre vented from turning on its axis, so that shout ders, collars, a'nd other projections can be hammered down with certainty to their iu tended size and form by means of the side of the hammer.
Having thus described the nature of my in vcntion, and the manner in which the same may be used, l desire to be understood that l do not wish to confine myself to any particle lar shape of the sect-ion of the upper halt' of the hammer-bar, orto any particular number of longitudinal fiat surfaces upon the same. any such change in its construction being but an unimportant deviation from the means herein described for accom plishing the same object; but what at present, with respect to the improved construction of steam-hammers patented by me in the Kingdom of Great Britnin, August G, lb, No. 1,855, 101mm as my lowersLnfling-boxes,itis QI'L'ect-na'lly prevented invention, and desire to Secure byietfeis Pm? from turning on its axis. ent, is-
