9 Claims. (01. 184-27) This invention relates to improvements in force feed lubricators of that class wherein lubricating fluid is supplied under pressure to places where required. An object of the invention is to provide in connection with a reservoir, a number of pumpingunits having complemental leads connected therewith, and actuating means therefor constructed and arranged so that any one of the units may be readily removed from the reservoir independently without disturbing any of the other units or the actuating means, to permit replacement of the units when required. Other objects and advantages will appear in the following description.
- An illustrative embodiment of the invention is shown in the accompanying drawings, in which:-
Fig. 1 is a side elevation of a structure in which the invention is embodied, parts being broken away;
7 Fig. 2 is a detail cross section of members for adjusting the stroke of a pumping unit, the section being on the line 2-2 of Fig. 1;
Fig. 3 is a front end elevation of the structure with parts broken away; and
Fig. 4 is a fragmentary plan view of the appliance, the cover being omitted.
The illustrative embodiment of the invention consists of a reservoir 1 for holding a supply of lubricating fluid, a series of pumping units re- 1 movably mounted in the reservoir, and actuating mechanism for the units.
The reservoir 1 is preferably in the form of a box provided with a removable cover 2 having a fill opening 3 that is closed by a suitable lid 4. The cover also has another opening 5 over which is positioned a glass dome 6 hereinafter referred to.
The pumping units each have a frame provided with horizontal and pendent portions 7 and 8 respectively. The horizontal portion of the frame has an elongated vertical opening 9 therein and a tubular front end constituting a pump cylinder 10. Also, the rear end of said portion is tubular and constitutes a guide 11. The outer ends of the cylinder and guide are threaded internally and externally, each being provided with an adjusting collar 12 engaging the external threads thereof that bears against the inner face of the adjacent end wall 13--14 of the reservoir. A head fixture 15 extends through the end wall 13 into the cylinder and has engagement with the internal threads thereof, and is provided with a jamb-nut 16 that bears against the outer face of said wall, whereby the corresponding end of the frame 7 is supported and secured in connection with the wall. The fixture is tubular and has therein a spring-pressed outlet check valve 17 for controlling the outflow of fluid from the cylinder 10. The rear end of the frame 7 is supported in connection with the end wall 14 of the reservoir by a sleeve nut 18 that extends through y the wall into the end of the guide 11 with which it has threaded engagement, and bears against the outer face of said wall. In this manner the frame is held firmly in adjusted position within the reservoir. 65
A yoke 19 is disposed in the slot 9 of the frame 7 and is provided at one end with a plunger 20 that extends into the pump cylinder 10, and at its opposite end with a stem 21 that extends into the. guide 11, the yoke, together with its plunger 70 and stem being adapted to have longitudinal reciprocating movement relative to the frame. The pendent portion 8 of the frame '7 has a pump cylinder 22 provided with a check valve controlled intake 23, a check-valve controlled outlet 24 and 7 a reciprocating plunger 25. Also, a screen 26 is secured to the frame beneath the cylinder through which liquid is drawn from the reservoir into the intake 23.
The plunger of the supply pump A is 3.0- 80 tuated by a bell-crank 27 that is secured by a pivot 28 to the frame. The lower arm of the bell-crank extends into a slot 29 in the plunger 25 and its upper arm projects into an elongated slot 30 in the stem 21. An adjusting screw 31 is disposed axially in the outer end of the stem and projects into the slot 30 so as to contact with the upper arm of the bell-crank and actuate it during the forward stroke of the stem. The said upper arm has more or less play between 0 the adjusting screw and the opposite end wall of the slot 30 accordingly as said screw is adjusted and the stroke length of the plunger 25 is thus varied. The adjusting screw has an elongated hexagonal head 32 that extends into 5 the hexangonal bore of a swivel 33 which is totatively mounted in the sleeve nut 18, there being a thimble 34 secured on the outer end of the swivel for manually turning it to thereby adjust the screw.
The cylinder 10 of the feed pump B has an intake 35 provided with a cup 36 that extends through the opening 5 in the cover 2 into the dome 6 and receive liquid from the supply pump A as it is delivered through the outlet duct 3'? 105 and gooseneck 38 connected therewith.
The actuating mechanism for the pumping units has a drive-shaft 39 which is rotatively mounted in bearing brackets 40 and 41 secured respectively in the side walls 42 and 43 of the 110 reservoir. The middle portion 39 of the driveshaft is hexagonal and has mounted thereon an eccentric 44 for each pumping unit and a bearing collar 45 adjacent each side of the ec centric that extends through an opening 46 made in the corresponding side of the frame 7. The openings 46 extend through the adjacent lower edges of the frame so as to permit removal of the frame by raising it bodily from the reservoir. The collars 45 have bearing contact with the faces of the frames 7 adjacent the correment of said frames is opposed in one direction as the yokes19 are driven in the opposite direction by their complemental-eccentrics 44. In this manner the end Walls 13 and 14 of the reservoir are relieved of the brunt of the strokes of the feed pump, and also as the pressure of the collars against the frames is opposite the pressure of the corresponding eccentrics against the yokes, lateral flexure of the drive shaft is averted. 1 The front and rear ends 19' and 19" of the yoke are spaced apart and the eccentric 44 is disposed therebetween so that upon rotation of the eccentric the yoke is reciprocated. A chafing plate 47 is removably secured to the yoke so as to extend snugly between the inner face of its front end 19 and the eccentric, so that it may be conveniently renewed after becoming worn. The drive-shaft 39 is actuated by an operating lever 48 provided with a driving head 49 contain-' ing a ratchet member 50, preferably of the roll or type, which is secured on the shaft, so that when the lever is swung to and fro the shaft is rotatively progressed in one direction. Also, another similar ratchet member 51 disposed in the bearing bracket 40 is secured to the shaft and acts to prevent retraction of the shaft. The head 49 is held in'operating position on the shaft by a nut 52 threaded thereon, and the lever 48 has attached thereto a connectingrod 53 by means of a suitable fixture 53. Reciprocating movement is'imparted'to the connectingirod by mechanical power derived from any suitable source (not shown) by making a suitable connection therewith in the usual manner. Upon the opposite end of the drive-shaft is loosely mounted a hand crank 54 provided with jaws 55 on its hub that, are adapted to: have engagement with a pin 56 secured transversely in'the shaft when the crank is adjusted outwardly on the shaft. Also, the shaft has a portion 57 adjacent the hand crank shaped and threaded to receive the driving head 49 and the nut .52 therefor. Thus, the mechanical actuating means for the shaft may be selectively applied to either end thereof.
In using the appliance, the head fixture 15 on the feed pump of each unit is connected by a leading or distributing pipe 58 with a bearing 01' other part (not shown) requiring lubrication. The reservoir is then filled with theoil to be distributed, and the supply pumps of the units 1 are primed by initially operating the hand crank.
As the drive-shaft is rotated the plungers of the supply and feed pumps are reciprocated and oil from the supply pump is discharged through the gooseneck into the cup on the intake of the'feed 1' pump which may be observed through the glass cylinder.
plunger the port is first closed thereby and the oil previously drawn into the cylinder is expelled therefrom throughthe head fixture into the distributing pipe.
The quantityof oil fed into the distributing pipe is limited'according to the amount discharged from the supply pump into the intake cup of the feed pump, which amount is dependent upon the stroke length of the supply pump plunger 25. Should the discharge from the gooseneck be insufficient, it may be increased by turning the thirnble 34 so as to move the screw 31 inwardly whereby the play of the bell-crank in the slot 30 is. decreased and the stroke of the plunger 25 increased. 7 Or, by turning the screw outwardly the play of the bell-crank is increased and the stroke of the plunger is correspondingly decreased, thus reducing the discharge from the gooseneck. This adjustment is preferably made while the appliance is being operated by the mechanical actuatingmeans; 1
One of the features of the invention is the manner in which the pumping units are connectedly related with the driving means and the reservoir, whereby the frames of the units overhang the drive-shaft so as to permit removal of the .units readily without effecting the driving 'means. And, another feature is the provision of the collars 12 on the frames bywhich the frames are adjustablycentered in the reservoir in proper relation with the bearing members 45', and also the arrangement of the head fixture l5 and :the'
