LUBRICATOR.

Specification of Letters Patent.

Patented Sept. 25,1906.

Application filed August 10,1905. Serial No. 273,554.

To all whom, it may concern.-

Be it known that I, JOSEPH J. SLAGEL, a citizen of the United States, and a resident of Fairbury, in the county of Livingston and State of Illinois, have invented a new and Improved Lubricator, of which the following is a full, clear, and exact description.

The invention relates to alubricator of that type used in connection with engines, particularly steam-engines, and embodying a pump for forcing the lubricant through a sight-feed device and from thence into the steam-pipe or other part of the engine, so that the oil passing into the engine with the steam lubrisure the proper action of the valves associ- 1 ated with the pump.

A further object of the invention is to improve the device for driving the pump from a moving part of the engine.

To these ends the invention resides in certain special features of construction and relative arrangement of parts, which will be fully set forth hereinafter and particularly pointed out in the claims.

Reference is to be had to the accompanying drawings, which illustrate as an example the preferred embodiment of my invention, in which Figure 1 is an elevational view showing the invention applied to an engine. Fig. 2 is a side elevation of the reservoir, showing the pump in section. Fig. 3 is an enlarged section taken vertically through the reservoir on the line 3 3 in Fig. i and showing the admission-valve of the pump in section. Fig. 4. is a plan view with parts in section. Fig. 5 is a detail view of the. ratchet and the peculiar pawl for driving the pump and valve, with part in section on the line 5 5 in Fig. 3; and Fig. 6 is a section showing the sight-feed device.

Referring to Fig. 1, 10 indicates the steampipe of an engine, of which 11 is the cylinder; 12, the piston-rod; 14, the cross-head; 15, the cross-head guide; 16, the connectingrod, and 17 the frame.

18 indicates the reservoir, adapted to contain the lubricant. This reservoir is pro vided with a base 18*, enabling it to be firmly bolted in place on the frame of the engine. The reservoir also has a cover 18. which is secured by a tie-rod 19, passing through the cover and down to the bottom of the reser- 20 indicates a heating-pipe, which is preferably Ushaped, as shown in Fig. 4, and passes into the reservoir. This pipe is adapted to have steam circulated through it so as to keep the lubricant in the reservoir at the proper degree of fluidity.

The cover 18 carries bearings 21, in which a revoluble shaft 22 is mounted, this shaft passing horizontally over the reservoir, as shown. At one end this shaft is provided with a ratchet-wheel 23, and this is engaged by a pawl 24, suitably mounted on the reser voir and serving to prevent back movement of the shaft and ratchet. Loosely mounted on the shaft 22, alongside of the ratchet 23,

are two arms and 26. These arms lie alongside of each other directly adjacent to the ratchet-wheel. As shown best in Fig. 5, the arm 25 has a lug 27, in which a screw 28 is adjustably held by nuts 29. The arm 26 has a bracket 30, having an orifice therein loosely receiving the screw 28, and the adj acent end of the screw is pivoted, as indicated at 31, to a pawl 32, which is itself pivoted between lugs 33, projecting, respectively, from the bracket and the lever 26. The bracket 30 also has an arm 34 projecting therefrom, which arm lies over the ratchet 23 at the side opposite that on which the levers 25 and 26 are located, the .arm serving to hold the levers in parallelism with the ratchet and preventing lateral movement of the parts. A spring encircles the screw 28 and bears between the bracket 30 and pawl 32, normally holding the parts in the position shown in Fig. 5. By this arrangement the pawl 32 is held in proper engagement with the ratchet 23, allowing the pawl to move idly over the ratchet as the levers 25 and 26 swing from right to left, (referring to Fig. 5,) but causing the pawl firmly to engage the ratchet upon the reversal of the movement of the levers. During the idle movement of the pawl the lever 26 is swung relatively to the lever 25, the free end of the lever and the pivoted end of the pawl coming into proximity with each other, and upon the active movement of the pawl the parts reassume the position shown in Fig. 5. The lower end of the lever 25 is connected by a link 36 with a moving part of the enginefor example, the connecting-rod 16so that the levers 25 and 26 and their attachment will be given a vibrating motion in time with the operation of the engine, which vibration through the ratchet devices above described is transmitted to the shaft 22 in the form of a step-by-step rotary movement. By adjusting the nut 29 the thread of the pawl may be regulated.

The shaft 22 carries at the end opposite the ratchet 23 a crank-disk 37, to which a connecting-rod 38 is joined. The connecting-rod 38 is articulated to the plunger 39 of the oil-pump 40, which is fastened to the outside of the reservoir 18. The oil-pump 40 is fed from the reservoir through the ipe 41, the receiving end of which is controlliedby a rotating plug-valve-42. This valve has a joint 43, connecting it with a rock-shaft 44. The roclcshaft passes up through the cover 18 of the reservoir and has a crank-arm 45, attached to its upper end. This crank-arm has two lugs 46, in which operate adjustingscrews 47. To the arm is pivoted an arm 48. This arm extends between the adjusting-screws 47, so that by manipulating the screws the position of the arm 48 relative to the arm 45 may be changed at will. The arm 48 is joined to the pin connecting the link 36 to the crank-disk 37 by means of a link 49, having pivotal connection with said pin, and a universal connection withthe arm 48, said universal connection being indicated at 50 in Fig. 4. Consequently 'upon the rotation of the shaft 22 to operate the pumpplunger 39 the shaft 44 will be rocked and the valve-plug42 will be opened. Byproper positioning of the (parts this opening of the valve may be time to take place at the correct periodwhich is to say, the suction period of the pump. By providing a positively-o V erating valve I am assured of correct an certain operation, and the trouble due to clogging of the valve and pump by impurities in the oil is avoided.

51 indicates a' check-valve controlling the discharge from the pump, and 52 indicates a pipe carrying the oi to the sight-feed device.

The'sight-feed device comprises a body part 53, having a assage 54 therein, to which the pipe 52 eads. Communicating with this passage is a tubular branch 55, in engagement with which a glass tube 56 is held by means of a collar 57. 58 indicates a nipple through which the oil is forced into the sight-tube 56. The upper end of the tube 56 is engaged by a tubular branch 59. 60 indicates a gland which operates on a art of the tubular branch 59 and serves to e ect a tight joint between the tubular branches. The tubular branch 59 leads to a passage 61 in the upper end of the body part 53, and from this passage a tube 62 passes to the steam-pipe 10 of the engine. With this arrangement upon the operation of the pump 40 the lubricant is forced in pulsations through the pipe 52 and entering thesightfeed device passes in drops from the nipple 58 through the pipe, where the feeding action may be observed by the person in charge, and thence to the engine. The device may be regulated to regulate the amount of .oil forced into the engine, thus placing'the lubricator under perfect control.

63 indicates a drain-passage in the branch 55, and 64 indicates a needle-valve controlling the same.

Having thus described the preferred 'form of my invention, what I claim. as new, and desire to secure by Letters Patent, is-

1. The combination of a pump, a rotating shaft, a crank thereon, a connection between the crank and pump to operate the latter, an admission-valve for the" pump, a rock-shaft in connection with the admission-Valve, an arm in connection with the rock-shaft, and a link connecting the arm with said crank for the purpose specified.

2. The combination of a pump, a rotating shaft, a crank thereon, a connection between the crank and pump, an admission-valve for the pump, a rock-shaft in connection with said valve, an arm attached. to the rock-shaft, a second arm pivoted on the first arm, means for adjustably holding said arms in fixed relation, and a link connecting the secondnamed arm with said crank, for the purpose specified.
