Application filed February 24, 1909. Serial I 10. 479,764.
To all whom it may concern: V V Be itknown that 1, JAMES M. Sonoonr MAKER, Jr., a residentof Pittsburgh, in the.
county of Allegheny and'State ofPennsyL Vania, have invented a new and useful Im-' provement in Motor Fire-Engines; and I the clutch mechanism by means of which the j car may be controlled with perfect case when traveling to or from a fire and at the same time absolutely positive so that it cannot slip when thrown into position to do the pumping.
cl aimed.
Referring to the drawings Figure l is a, side elevation of my improved fire engine partly in section; Fig. 2 is an enlarged plan 1 View of a portion of the fire en ine show-f ing the clutch mechanism' and t e manner of operating the same; Fig: '3 is a cross section on the line 3-3 Fig. 2; Fig. 4: is'a section taken on the line 4-4 Fig. 2; Figs. 5 and 6 are enlarged details of the slides; Fig. 7 is an enlarged side view of a portion of the machine showing the manner'of controlling the circulation through the pumps and radiator; and Figs. 8 and 9 are details of the valve mechanism.
While I have illustrated in invention in connection with an automobi e driven by a gasolene engine, I do not desire to limit myself in any way to the kind of motor or driving the car and i I arms 24 pass between said spokes, as clearly power employed for is the gasolen'e engine 4 which may beof any suitable construction provided -witli proper valves and other parts which I have not deemed it necessary to illustrate in detail, as the engine forms no part 'ofin vention. The engine shaft 5 is provided with the fiy-wheel 6, the shaft being secured a said fiy-wheel by means of the integral flange 7 bolted to said fiy-wheel by means of the bolts 8. The fly-wheel 6 is provided with the annular cone face 9 and with the internal gear 10 which is bolted to said flywheel 6 by means of the bolts 8 and 11. The main clutch shaft 12 is square or polygonal in cross section and its extreme outer end portion is round to engage a bearing or seat in the fly-wheel 6 so that said fiy-wheel may rotate freely on said shaft 12 when not engaged by the clutch mechanism. The square portion of the shaft 12extends to the flange 1a which is preferably formed integral with the shaft 12 and said flange forms the backing or abutment for the clutch spring 15 which is interposed between the said flange It and the square sleeve or shaft 16. At the forward end of the shaft 16 is the collar 17 from which lead the spokes 18 of the cone 19. The rim or periphery of the cone 19 is A further object of my invention is to improve such fire engines in other respects; all of which embodies, generally stated, the construction hereinafter set forth and furnished with. a facing 20 of leather, or
other suitable material to give the proper v the fly-wheel 6 so as to form a snug and close fit therewith. At the rear end of the shaft 16 is the grooved annulus 21 preferably formed'integral with the shaft 16 and providedwith ball thrust bearings.
Slidable on the square shaft 16 is the grooved annulus 22. Bolted or otherwise secured. to the annulus 22 is the split ring 23 and extending forwardly from said split ring are the arms 24 connected to the split ring 25 which encircles the groove in the collar 26 which is adapted to slide on the shaft 12. The collar 26 forms part of the spur gear 27, which is likewise slidable on'the shaft 12 and is adapted to be thrown into engagement with the internal gear lO on the fly-wheel 6. The spokes 18 of the cone 19 are arranged at such an angle with reference to the rim of the cone to provide room for the movement of the spur gear 27 while the is the foot-lever 29. Secured to said shaft 28 and extending down therefrom is the arm 30 which is connected by the link 31 to the arm 32 pivoted to the stud 33 on the frame. The upper end of the arm 32 is conmated by the turnbuckle 34 with the shaft 35 journaled in the frame. An arm 36 is secured to the shaft 35 and said arm is provided with the yoke 37 which engages the groove of the annulus 21. It will be apparent that when the operator applies his foot to the pedal 38 of the lever 29 and applies pressure the'shaft 35 through the intermediate parts will be moved so as to opcrate the yoke 37 and move the annulus 21 secured to the shaft 16 whereby the cone 19 will be withdrawn from engagement with the conical face of the fly Wheel 6. The second foot lever 40 engages the shaft 28 by means of the collar 41, said collar being loosely mounted on said shaft. This lever 40 is the foot brake lever and a rod 43 is connected to said lever above the pivotal point, said rod extending back to operate a brake band of the braking mechanism which it has not been deemed necessary to illustrate as it forms no part of the present invention.
The transmission box 46 contains the gears of the ordinary construction and as the transmission mechanism forms no ,part of my invention I have not deemed it necessary to illustrate the same in detail. A hand lever A is provided which operates the transmission mechanism' and by means of this lever A the transmission may be brought to neutral position. the forward and reverse speeds of the car by the different engagement of gears in the transmission box. The hand lever B is for the emergency brake which has not been illustrated.
To provide for the throwing of the spur gear 27 into engagement with the internal gear-10 on the fly-wheel I employ the following mechanism: A shaft 50 is supported by the frame and on said shaft is the hollow sleeve or shaft 51. Connected to the outer end of the shaft 51 is the lever 52 which is adapted to move in the quadrant 53. This quadrant 53 is divided by tl partition 54 so as to make a U-shaped slot within which the lever 52 plays. Connected to the inner end of the hollow shaft 51 is the downwardly extending arm 55 which engagesa seat 56 or 57 in the slides 58 and 59. These slides move in suitable guides in the bottom of the box 60 which is supported by the 'in -said slides. The said slides may be released by applying sutlicient force to move the latches 61 from the seat 62, but said This leve' also controls valve to the pump 83.
sliding arm 68 mounted on the rod 69. This sliding rod 68 has the yoke 68 which engages the annulus 70, forming part of'the gear 71 on the main shaft 12. This gear 71 is adapted to be drawn'into engagement with the gear 72 on the shaft 73 of the pump 74. This pump 74 may be of any suitable construction, that shown being an ordinary gear pump although'I have not deemed it necessary to illustrate the internal construction thereof.
The shaft 12 extends back into the transmission case in the ordinary manner and power to drive the rear wheels 3 of the car is transmitted to the rear axle by means of the chain 75 in the ordinary manner.
.The inlet pipe 76 leading to the pump enters said pump from below and the outlet pipe 77 is connected up to the air chamber 78. The discharge pipe 79 is provided with the outletsSO to which the hose may be connected, said outlets being provided with suitable valves 81. 1
To provide for the cooling of the engine when the automobile is running, I provide the ordinary pipe connections and radiator 82, the circulation through the water jackets of the engines being effected by means of the small pump 83. This arrangement is up to this point the same as in all automobiles,
nected to the crank arm 96 which is operated by the handle 97 located within convenient reach of the operator and this handle 97 is .engine pipes 92 and 91 to the radiator,
thence by pipes 87 and 88 through the pump, whereby the circulation is maintained. When the engine, however, is in operation at the fire the operator bymeans of the handle 97 throws the valves 86 and 89 in such position that the pipes 87 and 91 to the radiator are closed and the pipes 85 and 90 opened. In this manner the water is admitted from the main pump 74 and passes through the valve 86 and by the pipe 88, goes through the pump 83 and through the engine and then by means of the pipe 92 through the valve 89 and pipe 90 back to the suction end of the main pump. In this manner a positive and rapid circulation is obtained through the engine to prevent the heating up of the parts.
I provide at the rear of the engine seats for the necessary firemen and provision may be made for carrying reels of hose, babcocks,
A seat 98 is provided for the driver of the car and all the hand and foot levers are in convenient pos1- tion to be reached by the driver so that he has all the parts under complete control and ready of access.
When the machine is traveling to'the fire the power from the engine will be transmitted through the crank Shilrft 5, fly-wheel and cone to the shaft 12 and thence to the transmission gear in the ordinary manner. Upon arrival at the fire, the operator with his foot on the foot lever 29 throws the cone 19 out of engagement with the fiywheel which cuts off the power to the transmission and brings the car to a standstill while the engine continues to run. By the hand lever A he brings the transmission gears to neutral position. The connections having been made meantime with the fire hydrant the power is applied to operate the pump and this is accomplished by means of the lever 52. This lever is thrown forward which will act to move the slide 58 in such position as to move the arm 67 and through it the gear wheel 71 into engagement with the gear wheel 72. Just as soon as the operator removes his foot from-the foot lever 29 the spring 15 forces the cone into engagement with the fly-wheel 6 and power is transmitted to the shaft 12 and the gear wheel 71 being in engagement with the gear'wheel '72 power is transmitted to the pump 74:.
In order to prevent any possible chance of the slipping of the cone 19 in the fly-wheel when the loadis increased by the operation of the pump I have rovided the auxiliary drive which is obtalned by throwing the spur pinion into engagement with the internal gear 10. This is accomplished by the operation of the lever 52. As stated above, the lever was moved forward to throw the gear 71 into engagement withthe gear 72. the partition 54 and through the inner branch of the U-shaped slot, whereupon engagement is made with the slide 59 and by moving the lever back the slide 59 is moved and through its connections with the yoke 66 the annulus 22' is moved'so as to advance the spur gearv27 into engagement with the internal gear 10. Owing to the factthat the spur gear 27 is in engagement with the square portion of the shaft 12 the spur gear 27 has been rotating. at the same rate of speed asthe fly wheel so that when said spur gear is thrown to engage the internal gear of said fly-wheel the connection between the gears takes place without any undue strain or the danger of mutilating or stripping the teeth of the gears.
What I claim is:
1. In an automobile fire engine, the combination of an engine, a shaft driven thereby, a fly-wheel on said shaft, a second shaft, a clutch member on said second shaft adapted to engage said fly-wheel, a slidable gear wheel on said shaft, a pump, a pump shaft, a gear on said pump shaft with which said first named gear is adapted to engage, slides, rock shafts, connections between said rock shafts and said clutch member and sliding gear, a lever, and connections between said lever and said slides, whereby the clutch member and sliding gear may be operated independently of each other.
