Specification of Letters Patent. Patented Aug, 24:, 1909.

Application filed marc h23, 1909. Serial No. 485,312.

To all whom it may concern:

Be it known that we, FRANK B. HUNT-ER and HARRY B. HUNTER, citizens of the United States, residing at Memphis, in the county of Shelby and State of'Tennessee, have invented certain new and useful 1mprovcments in Combined Fire-Engine and Mechanical Propelling Means; and we do hereby declare the'following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it'appertains to make and use the same.

Our invention relates to new and useful improvements in combined fire engines and mechanical propelling means therefor and our object is to providemeans for mounting suitable umping mechanism upon a motorpropelled vehicle and a further object is to provide means for connecting the motor to the pump for pumping water or to the propelling parts of the vehicle for moving the ap aratus'from place to lace.

ther objects and a vantages will be hereinafter referred to and more particularly pointed out in the claims.

In the accom anying drawings,mal ing part of this app ication, Figure 1 is a top plan view of a motor propelled vehicle showing pumps mounted thereon. Fig. 2 is a side elevation thereof, and, Fig. 3 is a detail sectional view through portions of the driving mechanism for the vchicle'showing themanner of applying power either to the pump or vehicle.

Referring to thedrawings in which similar reference numerals designate corresponding parts throughout the several views, .1 indicates the frame of our improved device, at one end of which is provided any suitable form of centrifugal or' turbine pumps 2-, while 3 indicates the engines employed for operating the pump and propelling the vehicle, the frame 1 being mounted on any suitable form of supporting wheels 4.

The pumps 2 are provided with an intake 5, through which the water enters the pumps and '6 indicates the outlets to which the hose is attached when throwing water and in order to control the pressure and volume of Water discharged by the engine, we provide a suitable passage. 7, said passage having three-way cocks 8 at its ends, whereby the water may be directed through the pumps separately or in parallel, thereby giving a maximum capacity or, if desired, may be turned as to cause the water to first flow:

through one pump, then return through the assage and through the other pump, therey giving maximum pressure. The pumps 2 are driven from the crank shafts 9 of the engines 3 through the medium of pump shafts 10, said shafts 10 being connected with the crank'shafts 9 through the medium attached to frictlon clutch cones 14, which cones are adapted to engage the frictional faces of fly wheels 16, said iiy wheels being fixed to the crank shafts 9.

That portion of the flexible coupling attached to the cone 14 is hollowto receive a stem 17, which stem-extends from the end of the crankshaft- 9 through the cone 14 and substantiallythrough the hollow portion of the section of flexible coupling 13, a spring 1.8 surrounding that portion of the stem 17 within the hollow section and being adapted todirect pressure on the cone 14, thereby holding the cone in frictional engagement with the fly wheel, a washer 19 being fixed to the stem 17 by means of a nut 20, said washer forming a support for. one end of the spring.

That end of the driyingshaft 1] farthest from the flexible coupling 13 is provided with a clutch face 21, with which isadapted to engage a clutch 22 on the pump shaft 10 and as said clutch is rotatably fixed with the shaft 10, it will be readily seen that when said clutch is'moved into engagement with the clutch face 21 and power is applied to the driving shaft 11, the pump to which the I shaft 10 is attachcd, will be operated. In this manner, the pumps are given a direct drive from the. motor, thereby giving a greater efficiency to the pumps as there is no lost motion encountered between the pumps and engines. The same engines are cmploycd for propelling the vehicle and to accomplish this result, the driving sl it 11 is provided with a fixed gear 23, wi h which cooperates a sliding 24 carrid on a (hit ing shaft 25, said shaft being preferably Square and entering a square opening in the gear 24, whereby said gear will be caused to drive the shaft 25.

A propelling shaft 26 has one of its ends introduced in a socket 27 in the end of the shaft 2?, the SOUlCOtQd end of the shaft having a clutch face 28,'vvhich is adapted to be engaged with a clutch 29 at one end of a shifting gear 30, said gear being slidabl mounted upon a squared portion 3]. of the shaft 26, so that when thc clutch 29 is in engagement with the clutch face 28 and the gear 24 is in engageme i t with the gear 25-3, the shaft 26will be driven direct from the shaft 25.

'lhe end of the shaft 26 farthest from the shaft 25 is provided with a pinion 32, which mes with a bevel gear 33 on. the rear axle 34 of the vehicle, thereby rotating the axle when the shaftfi is rotated.

Should it be desired tolower the speed of the vehich-i, the gear 30 is moved away from the end of the shaft 25 and into engagement with a gear 35 on an auxiliarvshaft 36, said auxiliary shaft 36 being rotated through the medium of a driving gear 37 fixed to the auxiliarvshaft, said 3'; engaging a gear on the socketed end of the driving shaft 25, the transmission of the power in this roundabout why lessening the speed of the vehicle.

Should it be desired to still fin-ther lessen the speed of the vehicle, a second gear 3.) is mounted on the shaft 26 and in alinenient with a gear 40, also fixed to the auxiliary shaft 36,'said gears 39 and 40 being connected by an idler gear (not shown). The gears 24, 30 and 30 and the clutch 32 are provided with suitable thrust collars with which are adapted. to engage any suitable form of levers (not shown) for operating the gears and clutch to slide them on their respective shafts.

l. A device of the character described comprising a frame, axles mounted on said frame, supporting wheels for said axles, crank shafts, fly wheels attached to said crank. shafts and having friction faces, pumps carried by said frames, pump-shafts for said pumps, the axial. centers of which are in alincment with the axial centers of the crank-shafts, a driving shaft between said crank-shafts and said pump-shafts, said driving shaft having a socket to loosely receive the end of a pump shaft, a frictional clutch-cone adapted to engage the friction faces of said fly wheel, a flexible 'cou ling between said cone and said driving s raft, means to fix said pump shaft with relation to l l g I l l l said drivingshaft, said cone having a hollow stem between the same and said crank-shaft also having a stem. or extension received by said hollow stem and pro vided with a resilient member, adapted to hold said cone in frictional contact with the face of said fly wheel, a plurality of gears arranged for delivering the motion of said driving shaft and a shaft of a vehicle also provided with a plurality of gears adapted to mesh with the aforesaid gears.

Z In a comltincdiire engine, and motorpi'opelled vehicle, the combination with a frame, axles on said frame and supporting wheels for said axles; of engines carried by the frames, crank shafts for said engines, fly wheels attached to the crunh shafts and having; friction faces, pumps carried by said frame, pump shafts for'said pumps, the axial centers of which are in alhn'inent with the axial centers of the crank shafts, a driving shaft between the crank shaft and pump shaft, said driving shaft having a socket toloosely receive the end. of the pump shaft, a fictional clutch cone adapted to engage the said coupling,

friction face of the fly wheel, a flexible cou ling between the cone and driving sha 't, means to fix the pump shaft With the driving shafts and a plurality of gears extending from the driving shaft to one of the axles of the vehicle, whereby power may be applied through said gears to propel the vehicle.

3. In a device of the class described, the combination with pumps and shafts for said pumps of engines for said pumps, crank shafts for the engines, said crank shafts be ing in alinement wi h the axial centers of the pump shafts, driving shafts having SO0l-iets' therein to loosely receive the pump shafts, fly wheels on the crank shafts having frictional faces, frictional clutch cones adapted to cooperate with the friction faces of the fly wheels, a flexible connection between the cones and driving shafts, means to yieldingly hold the cones in engagement with the friction faces and a clutch mechanism adapted to ilX the pump shafts with the driving, shafts In testimony'whereof we have signed our names to this specification in the presence of two subscribing witnesses.
