Eerie-,1 1% o. 212K121 1.55 a [com it may concern: Be it known that I Fnnncnron W. liownorrorr, a citizen of the United States, residing at Earlier, in the county of Koochiching and State of Minnesota, have invented new and useful Improvements in Gas-Engine Starting Devices, of which the following is a specification.

This invention relates to a starting device for a gas engine, and the object is to provide manually operated means of improved construction for use on engines of large'capacity for producing the initial explosion after the engine has been primed and the charge has been compressed.

The invention consists in providing manually operated means of novel construction acting in conjunction with the automati cally operating ignition devices of substantially the form now employed. I

Fig. 2 is a top plan view oi the construction shown in Fig.- 1.

iii s. 3 and 4t are detached views in perspect ve of certain elements or the device, described below.

Fig. 5 is a section through the mounting and guiding means for the reciprocable bar, the bar being shown in Fig. 3 and a portion of the guiding means in Fig. i.

Fig. 6 is a' perspective view showing a portion of the contact-making mechanism controlled by a trigger mounted on an arm of the reciprocable bar.

Referring to the drawings in detail, a cylinder is designated 10 and the oscillating arm/controlling the operation of the ignb tioii mechanism in the well known manner is shown at 14 being mounted at 15. Sue

side of a circuit is designated 16 and leads from a battery 17 through any suitable insulating connection 20. This arm 14: carries a pivotally mounted latch member or the like designated 21 cooperating with a trig g'er described below and constituting a part plication is based.

A hand lever 25 is pivotally a 26 and has pivotal connection at 2'? with a bar 28 slotted longitudinally as shown at 29% This slotted portion is engaged by a roller 30 carried on a bolt or the like 31 having: an

elongated head. 32 and is cgll'OVldiGti with nut 33 on the opposite en The roller 3Q ignition device.

of the construction on which the present at)v mounted aiz' said oscillating sion, said means 28 and acts as a guiding member. The holi; 31 is mounted in a con having about the proportions shown and being secured in any suitable manner. The head 3:2 of the bolt passes through a slot 35 in the box and is given a quarter turn for the purpose of producing proper engagement.

A bar 28. carries a frame or the like designated 37, the frame being secured by means of bolts 38, and including ans-rm 39 having a beveled end 40,'and a plurality of fork members 42 extending parallelly and serving to pivotally mount a trigger i i which is under the controlof a coiled spring 45. This trigger includes an offset orhook portion to, and an offset portion 4:? constitut in a stop.

he oscillating member constituting a portion of the contact making" mechanism is designated 48 and includes a plurality oi? arms 49 and 50,arrn 49 being connected with a coiled spring 51, and the opnosite arm be ing engaged by the trigger n when the englue is to be started by the operation oi the In starting the engine after the latter has been primed and aiter compression has been secured, and the switch (not shown) controlling the electric circuit has been thrown in, thelever 25 is operated, the trigger 44- being in the position shown in Fig. 2, and arm 50 ofthe ignition mechanism is operated for producing a spark for the initial ill explosion. It will be understood that am 28 is returned to operative position, with the trigger 44: on the proper side of arm 50 to effect the operation thereof, this return movement of bar 28 being permitted in view oii'thepivotal and resilient mounting of trigger 44. Should the beveled'end 40 accidentally come into engagement, it will only be a' slight engagement and will not prevent the required movement of the elements.

What is claimed is;

1. In a device oi the class described, the

combination with. an oscillating element iorming' a portion of the ignition mechanism of a gas engine, means for operating member, and additional means engagingand operating the oscillating-n'i' mber for producing last mentioned comprising a reciprocable bar, and a pivotally and re siiiently mounted trigger carried thereby.

. 2, is a'devico oi the class described, a re the initial explociprocable bar, means for guiding the movement of the ignition mechanism of a gas engine, said trigger engaging the oscillating element, and means for engaging said oscillating member during the continued opera tion of the engine.

3. In 'a device of the class described, a reciprocable bar slotted longitudinally, means for operating said bar, a frame carried by the bar and including a longitudinally extending arm at one side of the frame, a plurality of longitudinally extending arms at the other side of the frame, a

trigger ivotally and resiliently mounted be:

tween t e arms last named, an oscillating member comprising an element of the ignition mechanism of a gas engine, said member being engaged by the trigger to produce the explosion of the initial charge, and means for engaging the oscillatingmember during the continued operation of the en- DS. In testimony whereof I afiix my signature.
