Specification of Letters Patent.

Patented Septat, 1912.

To all whom t may concern.'

Be it known that I, JOHN A. GERMoNrRnz,

a citizen of the United States of America, residing at Detroit, in the county of lVayne and State of Michigan, have invented certain new and useful Improvements in Engine-Starters of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to starters for eX- plosive engines of the type adapted to inject fuel charges into the cylinder, vthe object being to provide means for forcing the exact amount required into each cylindervvithout attention on the part of the operator, and means for regulating or varying the amount discharged to suit different motors.

The invention consists in the matters hereinafter set forth, and more particularly pointed out. in the appended claims. l

In the drawings, Figure 1 is a View in end elevation of a device embodying features ofy the invention showing a dash-board on which it is mounted in section; Fig. 2 is a plan View ofi the device with the operating lever broken away; Fig. 3 is aview partially in elevation and partially in vertical setion ofthe device; Fig. 4 is a view in section on line IV-IV of Fig. 3; and Fig. 5 is a view in section and detail showing a check valve connect-ion With a motor cylinder.

l As herein shown a casing 1 with a substantially cylindrical body is mounted on a suitable base 2 for attachment to the side of the dashboard. A valve seat 3 at one end of the bore of the casing forms the mouth of a supply tube 5 adapted to be connected by suitable exterior fittings and pipes With a source of fuel supply. A plurality of lateral bosses 6, corresponding in number` to the cylinders of the engine for which the starter 1s intended, have outlet passages 7 in communication with the `bore of the casing and are provided With suitable pipe fittinge 8 in connection with tubes which lead to cylinder inlet nipples.

A needle closure 9 for the seat 3 has a screwthreaded stem in engagement with the end of the casing 1 through which it eX- tends, a packing gland 11 of conventional type forming a close joint around it. A trip plate 12 with a shoulder or face substantially radial to the stem is secured on the outer portion thereof. A rock arm 13 is journaled on the stem and has a stop trip pin 13 adjustable transversely theretol in substantially parallel'relatio-n to the stem 9. `Thepar'ts'are so disposed that acoiled spring 14 in compression around the stem between a` stop collar 15 thereon and the 'adj acent face of the rock arm 12 projects the pin 13 across the radialfface of the plate 12 When the parts are in initial or normal position. An oblique or helically disposed segmental fiange 16 on the rock arm bears against a projection 17 on thebase 2 of the casing so that turningof the arm out- Wardly against the action of asuitably disposed spring' 18 causes the rock arm to travel toward the stop collar 15 against the spring 14. A push rod 19gin a suitable bushing 20 in the support is providedvvith a pedal Q1 and is pivoted at its inner end b a pin 22 to slotted fingers 23 of the roc arm 12. 'The connection between the push rod 19 and the rock arm fingers is such as to allow free movement of the rock arm longitudinally of the needle valve stem.

Each of the pipes that lead from one of thenipples 6 is connected to a fitting adapted to be inserted in the cylinder head over the valve in place of the usual priming cup. As herein vshown this fitting consists of a screwthreaded plug 24 havin 1 an enlarged upper endwith tapered an grooved valve seat 25.- A duct 26 leads lfrom the base of the valve seat into an oblique outlet 27 arranged to direct flow from the plug overthe piston' head, as shown for example, in Fig. 5. A check ball 28 lying on this grooved seat is retained in a screivthreaded member 29 by an inner tube 30 having an annular valve seat 31 at its lower end adapted to be closed by the lball against back pressure in the cylinder.

As aconvenient means of obtaining a tight joint, a beveled collar 3:2 on the tube 30 is seated in the correspondingly faced end'of the member 29 by a cap 33 to which the end of the supply tube is suitably secured. y

In operation endwise movement of the push rod by pressure'on the pedal throws the rock .uni over, and by engagement of the roch arm pin with the trip plaie, turns the struction may be made without departing self-seating closure for the'inlet, means for closure stem and thereby carries it away l from its valve seat. This admits a charge into the interior" of the casing. Before the rock arm has reached the' end of this stroke the cam flange thereon has moved it so that the pin releases the trip plate and the latter falls back under the iniiuence of' a. suitably disposed spring 34. As `a consequence of this arrangement, the charge admitted is dependent entirely upon the lengt-hv of time of engagement of the Yrock arm pin with the trip plate, and as the pin isv adjustable in thle trip plate, as bymeans of a check nut 35 or the like, the charge may be accurately gaged to meet diiferent requirements of service. Thus the device is applicable for use with motors of any type or size.

.Obviously,. changes in the details of con-- from the spirit of the invention and I do not care to limit myself to any particular form or arrangement of parts.

I claim 1. The combination with a motor having explosion chambers, 0f a casinghaving out-l lets each connected to one of the chambers and a fuel inlet common t0 all the outlets, a self-seating closure for the inlet, and means for moving the closure to open the inlet, adjustable te release the closure when the latter has moved any predetermined extent.

2. The combination with a motor having explosion chambers, of a casing having out lets each connected to one of the chambers and a fuel inletcommon to all th(V outlets, a self-seating closure to open the inlet, means for moving the closure to open the inlet, and operating connections between the closure and means, adapted to release the closure to seat itself when the latter has moved to' a predetermined point.

3. The combination with a motor `having explosion chambers, of a casing having out lets each connected to one of the chambers and a fuel. inlet common to all the outlets, .a

moving vthe closure to open the inlet, and operating connections between vthe closure and means, adjustable to release the closure to seat itself when the latter has moved to any predetermined extent.

4. The combination with a motor having explosion chambers, of a casing having outlets each connected to one of the chambers and a fuel inlet common to all the outlets, a

cable member adapted to engage and move the closure to open the inlet when the member is shifted in one direction, and to release the closure during the same movement when the closure moves a predetermined extent.

5. Thecombination with a motor having explosion chambers of a casing having outlets each connected to one of the chambers and a fuel inlet commen to all the outlets, a self-seating closure for the inlet, a reciprocable member for moving the closure to open Vthe inlet, and operating connections between the member and closure adapted to .engage the latter when the closure is moved in one .direction only and to release the closure to seat itself when the closure has moved a predetermined eXtent.

6.

The combination with a motor having explosion chambers, of a casing having outlets each connected to one of the chambers and an inlet, a valve closurey for the inlet, spring operated means for holding the closure seated, and means for positively opening the closure, arranged to release the latter to the action of` the spring operated means when the closure has been moved a predetermined extent.

8. The combination with a motor having explosion chambers, of a casing having outlets each connected to one of the chambers and an inlet common to the outlets, a valve closure for the inlet adapted to be moved by rotation to open the inlet, a reciprocable member, means operatively connecting the closure andl member to turn the former when the latter is shifted in one direction and to release the latter when it has turned to a predetermined point, and means fory auto matically returning the closure to initial closed position when released.
