T 0 all-whom it may concern:

Be it known that 1', CHARLES H. YOUNG, J13, a citizen of the United States, residing in Wayne, Dela-ware CountyyPennsyl- Vania, have invented certain Improvements in Pumps or Motors, of which the followin r is a specification.

y invention relates pumps or motors, and more particularly in that type of pump employed in meto'r fire engines.

The main object of my invention is to provide apump having certain features of reversibility rendering it adaptable without alteration to a large variety of standard commercial truck chassis.

1n the attached drawings:

Figure 1, is a front elevation ofa pump made in accordance with my invention;

Fig. 2, is a plan view of the pump;

Fig. 3, is a horizontal section on the line Fig. 4, is a front elevation similar to that of Fig. 1, but having the front plates of the gear casing removed;

Fig. 5, is an end elevation of the pump;

Fig. 6, is a fragmentary section on the line 66, Fig. 2, illustrating the details of the gear shift mechanism, and f Fig. 7 is an enlarged section on the line 7-7, Fig. 4.

With reference to the drawings, the pump comprises a main casing 1. adapted to be mounted laterally of a motor vehicle and including intake and discharge ducts 2 and 3 respectively, and a pump chamber 4 in which are mounted in the present instance a pair of rotors 5, 5.

As best shown in Fig. 3, the discharge duct 3 vertically overlies the intake 2, the pump chamber 4 with which the ducts'commu'nicate lying intermediate the two ducts and at their centers, the ducts extending from the pump chamberlaterally to each side in such manner that their ends may lie at the opposite sides of the vehicle upon which th pump is mounted. The ends of the intak duct 2 are provided with, caps 6, 6, Whi-h are screwed to the ends of the duct, while the ends of the discharge duct 3 are controlled by- valves 7, 7.

. To each side of the casing 1 and adapted to close the sides of the pump chamber 4 are pump heads 8, 8, said heads being identical and interchangeable, and each is proto improvements in vided with a pair of stuffing-boxes 9, 9, and bearings 10, 10, 'for the rotor shafts 11, 11, which are mounted in said heads. Adapted to be secured to the outer flanged face of one or other of the pump heads 8 is a drive unit casing comprising a body casing 12, which issymmetrically formed around its longitudinal center line and which is adapted to house a pair of intermeshing pinions 13, 13, on the projecting ends of the shafts 11, 11, a gear wheel 14 which meshes with one of the said gears 13, and a pinion 15 upon a shaft 16, which latter is mounted at the lower end of the said body casting.

T e gear 14, as best shown in Fig. 7, is c rried b a short shaft 17, bearings for which are ormed upon the inside of face plates 18, 18, secured to the opposite sides of the casing 12, said bearings, as indicated in Fig; 1, being disposed laterallyof the vertical center line of the plate in order that the gear may mesh with one of the plnions 13, while clearing the other. It will also be noted at this point that the plates 18, 18, are identical and therefore interchangeable, and are also symmetrically formed around their axes so as to render them reversible'l by reversing the plates, the bearings 18 Wlll be thrown to the opposite side of the vertical center'line whereby the gear 14 will be brought into mesh with the other of the pinions 13. this having the effect of reversing the rotation of the rotors. The gear 14 is, in the present instance, equipped with ball bearings 19.

As best shown in Fig. 7, one end of the shaft16 is mounted in a bearing 20 within a cover 21 secured to one side of the casing 12, while the opposite end which is' of reduced diameter extends'into a recess 22 within the enlarged of a shaft 24, which latter is mounted in a pair of bearings 25 and 26 in a cover casing 27, which latter is secured to that side of the casing 12 opposite the cover 21. Threaded extensions 28 and 29 extend from the exposed ends of the shafts 16 and 24 and provide means whereby secured in the drive shaft of the motor oft-he vehicle, the shaft 16 being always nearer I the engine than the shaft 24, which latter is It will be apparent that inner end portion 23 these shafts may "be I splined to and therefore slidable upon the shaft 16, and there is formed in the interior of the enlarged portion 23 of the shaft'24 an annular gear with which, the pinion 15 is adapted to mesh, said pinion and annular gear 30 thereby constituting a clutch for uniting the shafts 16 and 24. Means is provided for shifting the pinion 15 from the position in which it is shown in Fig. 7 in which it meshes with the gear 14, to a position in which it meshes with the annular r gear 30, and the reverse, said shifting means consisting in the present instance of a gear shift box 31 secured as} shown in Fig. 5 to one. side of the casing 12, in which box is mounted upon a .shaft 32 which extends through one side of the box 31, a forked shifting element 33 having arms 34, 34;, extending into opposite sides of an @annular recess 35 in the pinion 15, the shaft 32 being reciprocated iii the box 31 by means, in the present instance, of a lever 36 pivotally mounted on a bracket 37 secured to'the front of the casing 12,- the lower end of said lever being suitably connected with the exposed end of the said shaft 32, as best shown in t should be here stated that the cover flange 21 and the casing '27 are so designed as to be interchangeable whereby the relative positions of the shafts 16 and 24 may be reversed. 1

As previously described, the casing 12 is adapted to be'secured to one or other of the heads 8, as may be found desirable, and where the casing 12 is secured to one of the said heads, a casing 40 is provided for l attachment to-the other of the heads in place of the casting. In this manner, it will be clear' that the casing 12 may be positioned at either side of the pump body 1, andv it will further be noted that the casing 12 is so formed as to be itself reversible on the head to which it may be attached.

It will be apparent from the foregoing that the casing 12 and its various connected elements which go, to constitute the drive unit of the pump may be so reversed and interbhanged and positioned with respect to the body 1 of the pump as to render the pump with its drive unitadaptable for mounting upon many of the standard makes of motor vehicle, and that with this arrangement th most favorable positioning of the pump i the vehicle may be attained; It

, will also be apparent that with a pump constructed in this fashion, the parts may be standar ized with the reasonable assurance that the pump in its standard form can be adapted to nearly any chamis upon which it may be desired to mount it.
