more fully shown and described in the application for Letters Patent "of the United States, of whichthis application is a division, so that further description of the hose rack .45 is not deemed necessaryl A chemical tank I containing a fire extinguishing fluid is removably carried on the rear end ofv the vehicle A, and this chemical J tank I is rovided with a drum 1 for contain- 0. ing the c emical (see Fig. 3), the shaft I of the drum beiri journaled in a stand J, and on the said-she I are held su orting bearing blocks K,- as indicated in igs. 3 and 4.

A Specification of Letters Patent. Patented March 10, 190B. giiial application filed A ri 1 ,1907, Serial No. 368,568. Divided and this application filed September 24, It I 1 1907. SerialNo. 394,309.

- interior of the druml, to allow the fire extinguishing fluid to-pass out of the drum 1 .through the valve L when opened and into the hose L to the nozzle thereof to extinguis h a fire. .Normally'the valve L is closed and the hose L is woun'don the drum I, and the entire chemical tank I is supported on therear end of the vehicle, and for this purpose the following arrangement is made: The blocks K previously mentioned fitinto 0 en bearings N 'held on swing arms N exten 'ng longitudinally and fulcrumed at N .to the vehicle body, and the said swing arms N are connected with ropes-or cables 0 extending upwardly and winding on a drum .0 journaled in suitable bearings on the vehicle A.

.The ends of the drum 0 are provided with handles or'crank arms 0 under the control of the fireman, to allow llllGfiI'lTlS N to swing downward until the stand J rests on the ground, the bearings N then being openat the rear, so that when the vehicle A is drawn forward the blocks K mo e out of the bearings N, and thechemical tank I remains standing on the ground while the vehicle A moves forward. In. a like manner when the vehicleis backed u the bearings N engage the blocks K, and tiien by the operator turning the-crank arms 0 the ropes or cables 0 are wound up on the drum O, to impart an u ward swinging motion to the swing arms N with a view to lift the tank I off the ground and to-hold it-supported from the rear-end of the vehicle, as plainly indicatedin Figs. land .2. 'When the swing arms N reach a horizontal position against the underside of the'vehicle body, then the free ends of the said swing arms are engaged by catches P, to lock theswing arms in a raised' position. The catches P are fulcrumed on the vehicle body and are pressed on by springs P so as to hold thecatches in engagement with the swing arms N. The upper ends of the catches P are ivotally connected by links P with arms I held on a transversely extending shaft P journaled in suitable bearings arranged on the vehicle body, and on the said shaft P are arranged handles P adapted to be taken hold of by a fireman, to move the same forward, with a view to disengage the catches P from the swing arms N immediately revious to lowering the chemical tank as before explained. Stops Q held on the rear end of the vehicle project close to therear faces of the blocks K, so as to hold the same in the bearings N and thus prevent accidental disengagement of the chemical tank I from its support on the rear end of the motor vehicle.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent:

1. In a fire-fighting apparatus, the combi- I nation with a wheeled vehicle, of a chemical vehicle, a chemica tank, and a su port for the same com rising arms mounte to swing on the vehic e and arranged to normally hold the said tank above the ground, the said swing arms being capable of releasing the said tank and delivermg it to the ground.

2. A fire-fightin apparatus comprising a l tank, a support for the same, the said support having swing arms for supporting the chemical tank and fulcrumed on the said vehicle, and a locking device for locking the said swing arms normallyin a raised position.

3. A fire-fightin apparatus comprising a vehicle, a chemica tank, a support for the same, the said support having swing arms for suppprting the chemical tank and fulcrumed on the said vehicle, a locking device for locking the said swing arms normally ina raised position, and manually controlled means arranged on the vehicle and connected with the said swing arms, to sw .g the latter down or up. 4. A fire-fighting apparatus comprising a vehicle, a chemical tank, a support for the same, the said support having swing arms for supporting the c emical tank and fulcrmned on the said, ehicle, and a stop on the vehicle for holding the chemical tank against accidental displacement on the said swing arms.

5. A fire-fighting apparatus comprising a vehicle, a chemical tank, a support for the same, the said support having swing arms for supporting the chemical tank and fulcrumed on the said vehicle, a manually controlled drum mounted on the vehicle, and cables winding on the said drum and connected with the said swing arms;

6. A fire-fighting apparatus. comprising a vehicle, and a chemical tank removably connected with the said vehicle, the said tank being in the form of a drum, 0; stand on which the said drum is mounted to turn, and

a hose adapted to wind on the said drum and connected at one end with the said drum.

7. A fire-fighting a paratus comprising a vehicle, and a chemica tank removablv connected with the said vehicle, the said tank bein in. the form of a drum, a stand on whic the said drum is mounted to turn, a hose ada ted to wind on the said drum and connects at one end with the said drum,

and a valve at the connection of the said hose with the said drum. 8. In a fire-fighting apparatus, a vehicle, a

tank, bearing blocks supported at the ends of the tank, and arms mounted to swing on a the vehicle and having open bearings for engaging the said bearing blocks, to support the tank.

9. A fire-fighting apparatus comprising a vehicle, a tank in the form of a drum, a

stand, the shaft of the drum being journaled I in said stand, bearing blocks held on the said shaft, and arms for supporting the tank and stand, the said arms being f'ulcrumed on the vehicle body to swing up and down and having open bearings for engaging the said hearing b ocks.

10. A fire-fi hting apparatus comprising a vehicle, a tan for containing a fire extinguishing fluid, arms for sup orting the tank at the rear end of the vehic e, the said arms being fulcrumed on the vehicle to swing up and down and provided at their free or rear ends with open bearings, the said tank being provided with hearing blocks for engagement by the said open bearings of the arms, manually controlled means connected with the arms for raising the same to lift the tank catches for locking said arms in the raised position, and means for preventing accidental disengagement of the bearing blocks from the said open bearin s of the arms.
