CROSS-HEAD FOR ENGINES AND GUIDE THEREFOR.
SPECIFICATION forming part of Letters Patent No. 636,647, dated November 7, 1899.
Application filed February 10, 1899. Serial No. 705,151. (No model.)
T0 all whom it may concern:
Be it known that I, JOHN WASHINGTO EISENHUTH, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Cross-Heads for Engines and Guides Therefor; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in cross-heads for piston-rods of engines, and is especially adapted for use upon gas-engines.
The object of my invention is to provide cross-heads for the pistons of engines which shall guide the same in their reciprocating movements with a minimum of friction, and also to so construct them that any wearor unevenness may be readily taken up and adjusted.
It consists in a cross-head secured to a piston-rod, guideways mounted upon a suitable frame, and friction-rollers mounted upon said cross-heads and engaging the said guideways, whereby the movement of the piston-rod will be properly directed.
It also consists in a cross-head for pistonrods of friction rollers mounted thereon, guideways mounted upon a suitable frame and engaging the said friction-rollers, and means for adjusting the guideways so as to take up any wear of the parts.
It further consists in certain other novel constructions, combinations, and arrangements of parts, as will be hereinafter described and claimed.
In the accompanying drawings, Figure 1 represents a vertical section through a crosshead constructed in accordance with my invention and attached to a piston-rod. Fig. 2 is a similar sectional view, but showing the use of a greater number of friction-rollers. Fig. 3 is an enlarged sectional view of a cross head and a guide upon which it runs, illustrating the manner of adjusting the same. Fig. 4 represents a detail view, in side elevation, of the same. Fig. 5 represents a detail sectional view of a cross-head, which passes through a slotted guide-plate; and Fig. 6 represents a detail sectional view through one of the friction-rollers, illustrating the means of I mounting the same upon ball-bearings.
In constructing engines which employ reciprocating pistons and piston rods, especially when these parts are intended to have a very rapid movement, as in the case of gas engines, it is desirable to guide the piston-rod in its movement so that there will be as little friction as possible and so that allowance can be made for the wear and tear upon the parts. For this purpose I contemplate constructing the cross-heads of such piston-rods so that they maybe guided by suitable guides and by roller-bearings interposed between them and the said guide.
In the drawings a portion of a gas-engine has been illustrated, showing the manner of attaching my improved cross-heads thereto. In order to guide the outer end of the pistonrod, suitable guides, as E, are secured to the frame of the engine and are adapted to be engaged by roller-bearings connected with the cross-head of each piston-rod. As illustrated in Fig. 1 of the drawings, the crosshead may be provided with an extension, as 6, adapted to extend through a slot formed in the guide-plate E and carrying bearing-rollers, as e, which engage the front and-rear surfaces of the guide-plate E, and thus form a guide to direct the movement of the pistonrods. While the rollers 6' may be of any suitable construction, yet I prefer to mount them on ball or roller bearings, as e (Illustrated in Fig. 1.) In this construction the roller 6' consists of an outer rim portion, between which and a stud or shaft 6 secured to the extension 6, are interposed balls or rollers to afford an antifriction-bearing for the said rim portion.
As seen in Fig. 6, I preferably construct the outer rim of such a roller with an inwardlyextending annular flange, as f, forming a dividing interior rib portion. Case-hardened steel sleeves, as f, are also inserted in the roller e, which form' cups upon each side of the annular projection f to receive the usual balls, as f". The shaft f of the roller is provided with cones, the cone f being fixed upon the shaft, while the cone f is adjustable thereon to hold the balls properly in place. An adjusting-nut, as f binds the adj ustingcone f in position. This construction forms a simple ball-bearing for rollers adapted for use upon my improved cross-head.
As illustrated in Figs. 2, 3, 4, and 5, the numbers ofrollers upon each side of the guideplate may be increased. As illustrated in the said figures, two rollers, as c 6 are mounted upon the crosshcad extension 6 in front of the guide-plate E, a single roller, as c, being mounted on the rear side of the said guideplate. As also illustrated in these figures, the rear roller may be made adjustable, being journaled in movable blocks, as 6 which slide in guide-slots, as e formed in the extensions of the cross-head. An adjustingscrew, as c, is adapted to engage the said block to adjust it with reference to the guideplate. It will be seen by this construction that any wear of the parts can be readily taken up by manipulating the adjusting-screw e. As illustrated in Fig. 3 of the drawings, the guide-plate, as E, may be made adjustable in the frame of the engine, it being in this instance mounted upon transverse rods, as IE and held in place by means of adjustingnuts E E It can be readily seen that by means of these nuts the guide-plates E can be adjusted accurately with respect to the piston-rod, and thus guide the same more perfectly.
It will be seen from the above description that my improved cross-head, with its antifriction-roller bearings, is especially well adapted for use upon rapidly-reciprocating piston-rods, and that by means of the adjustable mechanism the wear of the parts can be taken up at any time. The adjustable guides also afford further means for taking up wear and truing the parts.
Having now described my invention, what I desire to claim and secure by Letters Patent is 1. In a cross-head for piston-rods the combination with the head proper, of guides movably mounted upon the bars of a suitable frame so as to be adjustable thereon, adjustin g-nuts on the said bars adapted to hold said guides between them whereby the guides may be adjusted with respect to the piston-rods, friction-rollers interposed between the crosshead and the said guide, substantially as described.
2. In a cross-head for piston-rods the combination with the head proper secured to the piston-rod, of an extension-frame mounted thereon, friction-rollers mounted upon the said extension-frame, sliding blocks carrying one of the said friction-rollers moving in slots formed in the extension on the cross-head and set-screws for adjusting the position of said blocks whereby the friction-rollers may be adjusted to take up any wear of the parts, substantially as described.
3. The combination with a piston-rod of a cross-head mounted thereon a guide mounted upon a suitable frame, friction-rollers carried by the said cross-head, and moving upon each side of the said guide, the said friction-rollers being mounted upon studs formed upon the said cross-heads, roller-bearings interposed between the said studs and the rollers for reducing the friction thereof, substantially as described.
4. In a cross-head for pistolrrods, the combination with a head proper, of an extension formed thereon, a slotted guide-plate, mounted upon a suitable frame, said extension upon the cross-head extending through the slot in the guide-plate, friction-rollers secured to the cross-head, and to its extension so as to bear upon each side of said guide to properly direct the movements of the piston-rods, substantially as described.
In testimony whereof I hereunto aflix my signature in presence of two witnesses.
JOHN WASHINGTON EISENHUJII.
