Be it known that l, G-sonom W. "forms, a citizen of the United titetes, residing at Glendale, in' the county of Los Angeies and State of California, have inventednew and. useful Improvements in Air-Brakes and Means to Start Automobiles, of which the following is s.- s' eeifieetioii.

Ihe object of my invention is to provide an eutoeer with means to brake and start the car With air, utilizing the motion lost in stop- I aooomplish these objects by means of the device described herein end shown in the socompeny n orswing, which is adiogrsrnrnstic View 0 the run ning-geer of an :iutoeer with my broking end starting device in. piece tl'aereon.

Upon the frame A or" the car is trensverseiy mounted a, compression. air-cylinder B. Cori neoted therewith are the ports C end D, lead ing into the sir-pumps E and F, iii the cylin- (lore of which are mounted the pistons any H, adopted to reciprocate therein. The said pistons are Worlmbly sol-mooted with the crankshaft I, carrying in the center thereof the sproolret-wheei J. A sproclaet ohein K extends around one. over the eproeketw'heel J and the sprocket-Wheel L, rigidly affixed to the clutch M. This clutch is mounted ooexielly with the hind axle and is thrown into or out of engegement with the Clutch-drum N, keyed to one member of the hind axle, by means of the clutch-operating yoke O. This clutch is ogeretiyely ooimeoterl with the hend-lever which projects upwardly in close proximity to the seat of the driver.

. hein in motion. end. it heoomes deelrehie to.

Leading from the compression-cylinder is the port Q which communicates with the starting-cylinder R, the opening through sent port being oontrolied by the onto Slidably mounted in the startingylimler is the piston T, the rod U, upon Whioh'the some is mounted, carrying on its upper side the. rack V. This rod 'irojeots forwardly under the main driving-s ieit i T and brings the teeth of the rock in engagement with the spur-gear X, revolubly mounted on the driving-shaft and connected therewith by the ratchet Zr, permitting the rotation of the spur--geer loosely in one direction and preventing its rotation. on the shaft in the other direction. 111 the heed of the starting-cylinder I have rovided s stop-cock Y, adopted to he opens rind closed by the lever Zr i My rievice is opereted foilows The oer stop or brake the some, the hand-lever Pie thrown forward. line will ilhlOWthB clutch M into engagement with the dutch-drum N and cause the sprocket-Wheel to rotate car-Z ryiiig therewith the sprocket-chain K, which Wlii impart motion to the crank-shaft} and "cause the sir-pumps E and F to pump air into the ooiiipressioii-eylinder B. As the air becomes compressed in said. cylinder it will o ierete toloreke the ear es the ressure in the tank increased until the car 13 brought to s 'full. stop, at which. time there will be a great pressure of sir 111 the OOIIIPI'BSSIOll-GYlllldQl The amount of pressuretherein will be shown by the pressuregege a, disposed on the dash of the oer or elsewhere Where easily seen by the rhiyer.

the engine, the pressure of air in the compression-tank is utilized for that purpose in this ,"wey: The henrliever l) is thrown beekwerdiy, oer; I OPE-r8119 to close the valve Y and open the 'veiye S, permitting the air to enter freely through the port 3 into the starting-chamber it end eerrying forwardly the piston T. This Will impart inotioii to the (irivingeheft V1,,

, upon which the fly wheel (Z is mounted. When the piston T has advanced sufiioie ntiy for word to COIItiLCi) with the inwardly-projecting end oi the cutoff rod 6, the cutoff rod operas tively connected. with the ieversZ and a will. the some to movsiforwssi'ily en. open the Valve-"Y and at the some time close the valve S, thereby removing the pressure from the piston T and out/ting ofi the discharge ofair t'rom the compression-chamber. Spring T zissists in returning the piston to its n0rmoi position. v

When necessary to remove the sir-oressoro from the oompressioii-tenk, the heni leverf, connects i with the hell-crank lever f, eer nested in turn with the bell eroni c leyer g, is adopted to work the outwit valve k sod eyes or elose the said valve, cofitroliihg; thegport leading ironi the eompressionmyliuderiimo the open air. A horn may be connected at this or the other and of the eomyression chamber and sounded When'dosired. by the operation of the h'e iddeyer' laced for that purpose, or oonneetion mey e made there- Now "when it is desired to stirrt 'irig therewith the lovers c, which with to inflate the meumetie tires on the oer.
