UNTTED STATES PATENT ALBERT Ii. IDE, OF CHICAGO, ILLINOIS.

LUB'RICATING DEVICE FOR ENGINES.

SPECIFICATION forming part of Letters Patent No. 397,293, dated February 5, 1889.

Application filed A t 4, 1888. Serial No. 281,944. (No model.)

To all whom it may concern:

Be it known that I, ALBERT L. IDE, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Intbricating Devices for Engines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form apart of this specification.

This invention relates to improvements in steam, gas, or other engines, and more particularly to improvements in lubricating devices for the crank-shaft, connectingrod, cross-head, and other parts of such engines.

The invention consists in the matters hereinafter described,'and pointed out in the appended claims.

The invention is herein shown as illustrated in connection with a horizontal sta tionary engine of that class having two crankdisks; but the main features of the invention may be applied to engines of upright or other forms and to other than stationary engines.

The engineframe herein shown is similar in its general features of construction to the frame illustrated and described in a separate application for patent, Serial No. 213i, 607, filed February 20, 1888.

In the said drawings, I igui-e l. is a longitudinal section of an engine and frame illustrating my invention. Fig. 2 is a detail section of the same, taken upon line 2 2 of 1. Fig. 3 is a detail section showing a modification of the lubricating devices illustrated in Figs. 1 and As illustrated in the drawings, A is the engine-cylinder, and B is ahorizontal continuous frame or bed supporting the bearings of the crank-shaft at one end and the cylinder A at its opposite end, the cylinder being socured to the extreme end of the frame, so as to overhang the latter.

O is a crank-shaft, which has bearings 19 Z) at one end of the frame 13. Said shaft 0 is provided between the bearings b b with two crank-disks,(l C, in which is secured a crankpin, C

D is the piston-rod of the engine, which is attached to a cross-head, E, which is held in guides F F, formed upon the engine-frame. Said piston-rod connected with the crankpin (3 by means of a connecting-rod G, in the usual manner.

The engine-frame B contains certain novel features of construction, as set forth in said separate application, Serial No. 264,607, hereinbefore referred to. Said frame is provided with an overhanging cylindric part, b, to which the cylinder is attached, and the lower part of the frame is formed by a hollow base,

8. The main or upper portion of the frame B adjacent to the cross-head guides F F is tubular, and the lower wall of said tubular part of the frame is extended from the lower cross-head guide to form a wall, B which slopes downwardly beneath the crank-disks to the level of the bottom of the frame, the bearings b I) being supported by walls B forming extensions of the side walls of said tubular part.

B", Fig. 1., a vertical wall extending rearwardly from the side wall, B and united with a transverse end wall, B connecting the said side wall B with the corresponding side wall at the opposite side of the frame. Said end wall, 13 is located at the end of the frame exterior to the crank-disks C C, and forms, with the side walls, 13 and B, and the bottom wall, B, a basin or tank, B for con taining a quantity of oil or other lubricant, in which the peripheries of the crank-disks are immersed when the engine is running.

H is a removable cover, which is fitted to the adjacent margins of the side walls, B and B, the end wall, 13 and the adjacent margin of the tubular part B of the frame, and is shaped to completely inclose or cover the crank-disks O C. Said cover H serves to protect from dust and dirt the several mov ing parts within the f nine, as set forth in said separate application, and also serves, in connection with the engine-frame, to form a casing or housing, which operates, in connection with lubricating devices constructed as herein shown and claimed, to aid in supplying lubricant to the several bearings of the engine.

In the use of an engine-frame constructed to form a housing or casing which entirely incloses and surrounds the crank-disks and the cross-head guides, and which is provided in its lower part beneath the crank-disks with an oil-tank, B as shown and described, the crank-disks, when turned in a direction to carry theirlower parts or surfaces toward the engine-cylinder, act to take up and throw forward, mainly toward the cylinder, but also into other parts of the housing, drops or particles of the oil or other lubricant contained within the said receptacle B as indicated by the arrows in Fig. 1. The drops or particles of oil or lubricant thus thrown or cast upwardly and i'orwardly by the cranledisks will be distributml throughout the interior of the casing or housing and serve to afford a con-i tinual and abundantsupply of lubricant upon the surfaces of the eross-l'ieml guides, and will commonly afford a sultieiently abundant supply of lubricant tothe pivotal connection between the connecting-rod and the piston.

The cross-head illustrated in Fig. 1 is generally similar to that shown in a prior patent, l\'o. 321,726, dated July 7, 1885, said crosshead being hollow or of boxtorn1,and. eons" ting of a rectangular main part, I, in the side walls of which a wrist-pin,1, is supported, and. bearingplates I l attached to the upper and lower surfaces of the main part of the eross-heml. and directly engaging the guides.

In the eonstructit'm shown in Fig.1 the upper horizontal plate or wall, 1', ofthe main part 1 ot' the hollow cross-head is provided in its center with a depending conical or tapering projection, 11, which is located over areceptacle, g, placet'l upon the end of the coniu'zeting-rod t, and communicating by a passage, g, with the l)(atring-suriaee ol the crankpin I. In a construction of this kind the oil thrown by the action of the revolving crankdisks upon the under surface of said plate 1", or flowing to the under surface of the said plate as it is scraped from the upper crosshead guide, 1!, by the plate 1 will drop from the end of the projection 1 and thus enter the receptacle q, I'rom which it will flow to the bearing-surl'ace ot' the wrist-pin, thereby atl'ording an abundant supply olf lubricant to the same.

The head G of the eonnecting-rod is provided with an oil cup or receptacle, 5 which communicates with the bearing-surface of the brasses therein by means of a passage, g", said cup or receptacle in this instance being preferably elongated in the direction of the planes oi the crank-disks. Upon the under surface of the upper wall of the cover or housing II: is formed a depending serrated flange, N, having at its lower end a series of teeth or points, /1 )2, arranged over and in the same vertical plane with the oil cup or receptacle The said serrated flange N may of course be replaced by a series of separate points or depending nojections. In the operation of the device thus constructed a considerable portion of the oil thrown upon the under surface of the cover or housii'ig will flow downwardly upon and drip from the ends of the teeth or projections 11 n, and the oil thus dripping or falling from said projections will be caught by the said receptacle as the crank-pin rises in the revolution of the disks, thereby allording a continuous supply ol. lul'u'iez'int to the said receptacle for supplying the crank-pin.

In Fig. 3 is shown a eonsta'uetion substantially similar to that in Iiigs. '1. and 2, with the exception that two rows of teeth or projections, II n, are employed, which areadapteul to supply oil to two separate oilcups, q", upon the connectingrod head. 'lhis eonstrnetion will be uselul in case of that form olf head illustrattal in said Fig. 33, wherein the head is n'iade-in two parts connected by bolts, instead of being provided with brasses held upon the main part olf the rod by a strap, as illustrated in l igs. and L. p

.I, Fig. i], is a trough or reeept'acle extending across the rear end of: the wall of the covering or housing II, so as to receive the lubricant cast upon and running down the under surface ol? the rear part of the said cover II. This trough is connected with a pipe or tube, .l, provided with a valve, j, and arranged to discharge into an oil-cup located upon crankshai'tbearing. 'lhese :teatures ott' construction are shown and claimed in a separate application for patent, Serial No. itfitJlOS, tiled by me in the United Statcslatent Otliee February 20, 1838.

My invention embraces as one of its main features the combination, with an oil-tank containing a luln-ieant in which the crank disk or disks are immersed and turn, and a housing su rronnd ing said disks provid ed with tltlpfllltl in pointed projections, of a receptacle placed beneath said 'iointed projections to receive oil delivered to the said interior surface ol the housing and dripping or flowing from said pointed projectim'is, and a passage or passages connecting said receptacle with a surface to be oiled or lubricated; and I desire to claim this construction broadly as applied to the oiling of any moving parts of the engine, it being entirely obvious that the same 1i rinciples of construction and operation maybe employed for oiling stationary and other betn'ings as is used in oiling the crankpin and the wristpin in the engine herein illustrated.

I have herein shown the casing or housing surrounding the disks and other operative parts as being formed partially by the engine-lranie, which. is made of peculiar form for this purpose, and. partially as .t'ormed in or by the frame itself. As far as the operation of the lubricating device described and broadly lftlll'ltitl is conem'ned, however, itwill be readily seen that said tank may be separated from the frame and that an inclosing easing or housing for the operative parts of the engine maybe made otherwise than as above set forth. I do not therefore wish to limit my invention to a construction in a ho'usin or easing formed partially by the enginc-t'ranw or to any other specific features of construction in the said housing or casing itself, except as certain novel features of construction. in said parts, herein illustrated, may form the subject of specific -claims herein.

Certain novel features of construction in the particular lubrieatin g devices illustrated are herein specifically claimed as separate improvements in addition to the main features of the invention above set forth.

I claim as my invention 1. The combination, with an engine cra'nk- 1 shaft and a crank-disk connected therewith, of a casing or housing surrounding the disk, having an. oil tank or basin beneath said disk, said casing or housing being provided with a depending pointed projection, b y which the oil flowing from the inner surface of the casing or housing may be directed orcarried to a part to be lubricated.

2. The combination. of an engine crankshaft, a crank-disk connected therewith, and a housin or casing'surrounding the disk and provided with depending pointed projections upon the said housing or casing, and having an oil tank or basin beneath said disk, an oi l- .receptacle secured to the coiniecting-rod and arranged beneath said pointedprojections, and having a pipe and a passage leading from said oil-receptacle to the bearing-surface to be lubricated.

The combination, with an engine crankshaft, a crank-disk, connecting-rod, and cross head, of a casing or housing surrounding the disk, connecting-rod,and cross-head, and hav- 1 ing an oil tank or basin. beneath the disk, a wrist-pin in the cross-head engaged with the connecting-rod, and an oil-cup upon the said connecting-rod communieat ing with the bearl eating with the bearing-surface of the wristpin, said hollow cross-head being provided upon its upper wall with a depending projection located over the said oilcup, substantially as described.

5. The combination, with an engine crankshaft, a crank-disk, crank-pin, and connecting-rod, of a casing or housing surrounding the disk and having an oil tank or basin beneath the same, and provided with pointed projections, an oil-cup upon the connectingrod communicating with the bearing-surface of: the crank-pin, said pointed projections depending from. the top of said housing or casing over the oil-cup for the purpose of deliv ering to the said oil-cup oil thrown upon the housing by the disk, substantially as described.

In testimony that I claim the foregoing as my invention I affix my signature in presence of two witnesses.

ALBERT L. IDE.
