under numerous road conditions and sudden emergencies such as often occur when driving motor-vehicles that lack advantage of an invention such as the one presently described; for sakeof comparision, assume we are driving a vahicle equipped with thispresent invention, as follows:

(1) In rounding a curve or making a turn on aslippery road, weife'el the vehicle is in dangerof skiddingyand our first impulse is to slacken the speed by applying the brake and closingthe valve of the carburetor, and in doing so, wetendto stop the driving wheels from .rotatingand to start slipping sidewise; but this tendency is avoided by the automatic operation ofthe present device Whichkeeps the carburetor open and the driving wheels turningand taking tractive engagement .with the road .or track while the brakeis still applied; .so the vehicle slowly and safely pulls away from eachslipperyplace encountered, instead-of skidding ,intoaditch or down a bank .orinto the path ,of another vehicle.

I (2) When driving up a hill, if .for any reason the motor vehicle is stopped,.and if the emergency brake is not suflicient, or if the driver does not think it necessary to use the emergencybrake, the pressure from the foot-brake will accelerate'the motorenough to keep the motorrrunning ,while the operator shifts to low gear and starts again up-hill.

'(3) If, in cold weather, .or ifiorany reason the motor is running .badlyonatake-ofi, and has not warmed up or is inclined to stop when the foot is taken off .the accelerator-pedal, toapply such foot to the brake pedal, as often happens at astop-signal or light, this device gentlybut ,ef-

fectively, thru the brake-pressure, spurs or accelerates the carburetor to action.

Therefore; a further obiectof this inventionis to provide an e'ilectiveand practical means to automatically open the carburetor by simply applying the brakes either-gently or tightly .so the mctor of the vehicle ,keeps running even when the brakes are applied; also to provide means ope'ratable at the instrument-board to quickly. render said practicalmeans operative or inoperative to suit various conditionsof theroad a and climatic-effect on'the specific gravityof the hydraulic fluid used; also to provide for making the brake accelerator connection independent of operation or control *by the accelerator-control mechanismheretofore known and in use.

'Other objects and important -*ieatures are pointed out or impliedin the liollowing detail or description, inconnection with the accompanying drawings in which;

Fig.1 is -a-somewhat diagrammatic view of.;a motor-.vehicle-attachment, as one form of; my in vention, combined withparts of the brake-actuatingmeehanism and tacceleratorea-ctuating mechanism of 1a 1 motor-vehicle, the accelerator-valve sectional view similar'to Flg.'l,but;-showing another modification of some of'the elements.

In rather broad terms, the invention is an attachment 'for a motor-vehicle that includes .a brake pressurer appliance ill and a carburetoraccelerator-valve l I an'dis thecombination of an oscillatory unit ll-J3, l2u/'l'3,,,or l 212-1311 that includes an abutment-element [2, Ha orjlZb and ashaft 13 or I130, mounted for oscillatory movementsiin bearings 13b. and, l 9a. and normally united with said qcarburetoreaccelerator-rvalve, yielding means l4 normally engaged withsai'd unitfor normally securing said carburetor-ac.- celcrator-valve Ill iniits carburetor-closing position, (see Fig. "1) said abutment-element comprising a radial projection thatincludes an abutmentl2, l2d-orl26. -Anactuatinaarmli oril ia is journaled on. said .shaft and .is .normallvsubstantally 'againstsaid abutment, .andretractable pressilre operated .means j [5 l l iis provided for attachmentto andqperation by said brake-pressure appliance fonsWinging said arm 15 or 1511 on said shaftso as topressagainst andcooperate with said abutment .12, 12a :or .l2b, vfor moving said carburetor-accelerator-valve H from its normal carburetor-closin position, as in Fig. 1, to various non-closing positions.

The invention also includes accelerator-controlling means (at It) operable to secure said oscillatory unit with its carburetor-acceleratorvalve in various non-closing positions against pressure of said yielding means or spring i l while said pressure operatd means is retracted.

The said retractible pressure-operated means (i6l'l) constitutes a sub-combination compris ing a fluid-containing flexible. spring-y. arcuate tube It having a closed end-portion operatively* connected to said actuating arm (5 and having its other end (at lfib) in open communication with the master brake cylinder which is apressurefluid container 2a of said brake-pressure appliance It, whereby when said brake-pressure ap' pliance is operated and increases pressure to Vari ous degrees in said arcuate tube 15 so as to cause said closed end Hiato move toward said actuating arm 15, the latter is thereby caused to move the link H and therebyto move said carburetor-accelerator-valve I l to its various non-clos ng positions according to the said various degrees of pressure in said arcuate tube I16.

More specifically, the invention comprises an attachment for a motor-vehicle such as described above, and comprises the-combination of a plate i9-that is attachable to said motors-vehicle, the shaft i3 or 23a being mounted for oscillatory movements and having said carburetor-accelerator-valve i l united therewith in an axially fixed relation to said plate. Said fluid-containing. flexible springy arcuate tube it has its open end secured in a fixed relation to securing means 20 on said plate l9. Afluid-conducting tube 2! has one end in open communication with a, tube 22 of the.brake-pressure-appliance, while its other end is'in open communication with said springy arcuate tube I6, so the latter receives pressure irom-said brake-pressure appliance ill simultaneously with fluid pressure received by said brake through the tube 22; andthe adiustable link i! and arm IE or sea comprise means operatively connected to the closed end of the said arcuate. tube 16 and said shaft l3 or 30; for cooperating with the latter for opening said carburetor-accelerator-valve when said arouate tube 15 expands. (or tends to straighten) by pressure simultaneously applied to said arcuate tube [6 and to said brake by said brake-pressure appliance ID. i

The fluid-pressure may be either air, oil or other appropriate fluid; and the chamber 2t is not only a means for anchoring the open ends of tubes 56 and 2!, but is also a medium thru which the tubes [6 and v2| are in open communication with one another. a In Fig. 3, theelement 29 is closed air-tight by a gasket 26 which is clamped between it and the main plate l9; and the open ends or" the tubes I5 and Z! are preferably welded to the inner and outer surfaces of the unit 20.

When traveling where the function of this device is not needed or desired, it can be rendered ineffective or inoperative by closing a valve, preferably a needle-valve such as shown diagrammatically at 23; and the closing may wellbe efiected .by a flexible or jointed rod or wire, (not shown)". that extends to, the instru ment-panel of the motor-vehicle. This valve 23 may be left partly open at all times, that it is not intended to stop runningof the motorwhen the brake is applied for stoppin the motorvehicle, as at numerous street and highway crosslngs.

Under all conditions, it is desirable to prevent the valve II from being opened beyond certain limits, and never to the point of dead center of the elements l5 and H; so, an adjustable stop 24 is provided for the part "5a to abut against; such stop being here shown as a nut secured on the plate i9, and a thumb screw threaded therein to be advanced or retracted to various limits;

so the valve H is accordingly limited as to its various partly opened positions.

Whereas, Figs. 1, 2 and 4 show the cars We formed on the plate l2, Figs. 5 and 6 show the plate lZa and rod [21) formed without such ears, but show ears 50 on the actuating arm I511, and show the abutments of arms lZa and 12b at I212 and [2a. In Figs. 4 and 5, keys, or studs 53:; normally fit in notches or seats 12s to fix the plat s or abutment-members l2 and 12a on the shaft i3; whereas, in Fig. 6 the rod or abutmentmember IZb has its middle part snugly fitted in a radial opening through the shaft l3a.

Studs 23 in Firs. 4 and 5 are means to attach an end of the sprin i4 Whose other end is at-. tached to a stud l is fix d to the main plate 19. In Fig. 6, the spring-attaching means at H is a hook formed integrally with the rod iZb.

The brake-detached accelerator-controlling m ans 18 comprises an actuating arm similar to arms H5 or USA pivotally connected or connectible to a link 25 that extends to the accel ratohptdal of the motor-vehicle, and is operable independently of the brake-pressure appliance.

I have no intention to limit my patent protection to the precise d tails in the foregoing and on the drawings, for the invention is susceptible of numerous changes and modifications within the scope of the inventive ideas as implied and claimed.

My invention is claimed as follows:

1. In anattachment for a motor-vehicle that includes a brake-pressure appliance and a carburetor-accelerator-valve; the combination of a rigid unit that includes an abutment element and a rocker shaft fixed to one another and mounted for mutual oscillatory movements and normally united with said carburetor-accelerator-valve. yielding means normally engaged with said rigid unit in a proper relation for movably securing said 'carburetor-accelerator valve in its carburetor-closing position, said abutment-element comprisin a radial projection that includes an abutment, an actuating arm journaled on said shaft and normally substantially against said abutment, and means comprising a springy ar cuate tube that is extensible by internal fluidpressure and is connected to and operableby said brake-pressure appliance for swinging said arm on said shaft so as to press against and cooperate with said abutment for moving said carburetor-accelerator-valve from its normal carburetor-closing position to various non-closing positions. I v
