LIGHT COMPANY, OF DAYTON, OHIO, A CORPORATION DAYTON, OHIO, ASSIGNORS TO DELCO- OF DELAWARE PUMP Application tiled O ctober 25, 1926. ISerial No. 143,822.

This invention relates to improvements in a pumping device and particularly to that type of pumping device which includes a pump operatively. connected with a pump' operating mechanism, said pump operating mechanism being driven by a power device by means of a belt.

It is among the objects ofthe present invention to simplify the mounting of the pump. its operating mechanism and the power device, so that the pump and its (ip-.-

erating mechanism are rigidly secured 1n proper relation. The power device is so mounted that it may be adjusted to vary the tension of the belt connecting v.it with the pump operating mechanism, while maintaining the alignment between these two elements. A further object is to provide the pump operating mechanism with an improved lubricating device which will provide lubricant in proper amounts to the moving elementsthereof.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings, wherein a preferred form of embodiment of the present invention is clearly shown.

In the drawings:

Referring to the drawings and more particularly .to Fig. 1 the numeral 20 designates a pump having a cylinder 21 from which extends a pump rod 22. The pump has a flange 23 to which is secured the water tank 24. The cylinder 21 cent these feet the cylinder housing has a lug providing two parallel sides for purposes to: i

has a plurality of feet 25 extending from each side thereof, and adj athe housing there are provided two lugs 35 I and 36, the outer surfaces of which are pari allel and spaced the same distance as the parallel the-pump. Atthe end of housing 31, oppo-` site opening 33, there is provided another opening 37 of lesser size however than the opening 33. In this opening 37 there is provided a cover 38 having a packing gland 39 associated therewith. f

Inside the housing 31 there is provided a` cylinder 40 coaxial with the opening 37. Above the cylinder 40 and within the housing sides of the cylinder housing 31 of 31 .there is located a pocket 41 which communicates with the inside of the cylinder by means of vaperture 42. An upwardly sloping shelf 43 formed on the end of the cylinder and extending across the housing provides an entrance to this pocket in close proximity to the path of travel of an oil thrower ,to be described hereinafter.

a piston 44 being connected with one end of the connecting rod 45 by means of wrist pin' Within the cylinder 40 there is provided l 46. vAs shown in Figs. 1 and 5 the rod 22 extends from the pump, through the packing gland 39 of the pump operating member, and

has its screw-threaded end secured to the head j of the piston 44. Intermediate t-he pump and the pump operating members the rod 22 has a disc portion 22a, adapted .to be gripped by the tool for screwing the rod into the piston 44. On one side of the housing 31 there mil is provided anextension 48 in whichsthere is fitted a bearing 49 for supporting the drive shaft 50. On the outside end of .this shaft there is secured a pulley 51 adapted to receife the belt 52. On the opposite end of this shaft and inside the housing 31 there is secured vran eccentric 53'which is operatively connected to the strap port-ion 54 of the conneet-ing rod 45.

Attached to one side of the eccentric is a fan-shaped plate 55 having a plurality' of angular extensions 56. This plate is detailedly shown-in Fig. 7 and is of such a conformation and so mounted on the eccentric that as the eccentric rotates the extensions 56 will dip j movein close proximity to the said dished shelf as the eccentric rotates. The dished shelf has a passageway 61 communicating therewith which leads to an aperture 62 communicating in turn with the bearing 49 of shaft 50. In' Fig. 6 it may be seen that the pocket 41, adapted to receive lubricant and deliver the same to the cylinder 40 and `piston 44, is in direct alignment with and in the plane of operation of the eccentric 53. It may also be seen that the dished shelf 60 lies by the side'of the disc 55 carried by the eccentric 53.

When the pump operating device included in the housing 31 is operated by the rotation of the pulley 51 the shaft 50 will be rotated thus causing the eccentric 53 to reciprocate the piston 44 in the cylinder 40, consequently causing reciprocation in pump rod 22. Rotation of eccentric 53 will cause the extensions 56 of plate 55 to dip into the oi-l and pick up a certain amount thereof, and, due to centrifugal force the oil will be thrown straight forward into the pocket 4l to lubricate the piston and cylinder and due to the formation of the angular extension 56 lthe oil will be thrown sidewise against the wall of thev crankcase and then the oil will flow down said wall into the dished shelf 60 from whence it will How through passageway 61 and aperture 62 to lubricate the shaft 50. The pocket 41 and the dished -.Lelf 60 will consequently receive an oil supply directly from the oil throwing plate 55. Y

As has been mentioned before, the pump and the pump operating mechanism include parallel sides on the outside of their casings. To these sides are attached angle irons 7 O and 71 whichform a support for the entire pump Qassembly -including the power device. At ythe pump operating mechanism end of the angle irons and 1 there is provided a 'foot 72 which .engages the outside of the vertical gether also secure the one end of the foot 76 to the angle irons. The opposite end of the foot 76 is secured to the angle iron by means of the short bolts 77 provided in each angle iron. The purpose of this will be described hereinafter.

As shown in Fig. 1 the

angle irons

70 and 71 extend beyond the foot 76, and are held Aparallel due tothe fact that they are secured to the parallel and equally spaced sides of the pump and pump operating mechanism.

Referring to Figs. 2 and 3, the method of attaching the power device 80', shown in the form of an electric motor, is clearly illustrated. The electric motor is provided with the ordinary standard base 81 to which is attached a guide member 82 by means of studs 83. The ends of the guide member are upturned as at 84, the edges thereof engaging Vwith the bottomy of the base 81 of the motor.

This guide member 82 is of a width equal to the distance between the parallel sides of the pump and thus said guide member slidably fits between the vertical arms of the angle irons. The sides of the guide member adjacent the angle irons are open and a clamping bolt 85 extends transversely therethrough thus permitting the guide member to be slipped back and forth between the angle irons foi` the purpose of adjusting the belt 52. The front end of the guide member is cut away topermit clearance forthe head of bolts 77. The clamping bolt 85 has a head 87 engaging with the angle iron 71 while at the other end there is provided a nut 88 adapted to .be screwed against the vertical angle iron 70 for simultaneously clamplng the angle"

irons

70 and 71 and the guide member 82 together. By loosening this nut y88 the motor withits guide member 82 may be slid back and forth along the angle irons for the purpose of adjusting the tension of belt 52. By this structure adjustments may be made with- -out effecting the alignment between the

pulleys

51 and 86 of the pump drivin mechanisrn and the motor respectively. fter the guide member 82 is once secured in correct alignment on the motor base 81 it need not be removed even when it is desired to remove .the motor from the angle irons for any purf 23 of the pump. A small lug or extension 90 is provided on the pump operating mechamsm, normally in Ispaced relation with the tank 24 to permit easy application of the tank to the iange 23,y however, providing a sup- :.\port for said tank if any undue load be placed thereon which support would substantially prevent any strain'on the liange 23.
