Application filed June 4, i904. Serial No. 211,174. I

To all whom, Ait Hwy concern:

Be it known that I, JOHN BRUCEY MORRISON,

in the county of Wood and State of Ohio, have invented certain new and usefulImprovements in Gas-Engine Starters; andI do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to w-hich it appertains to make and use the same, reference being had tothe accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in starters for gasengines; and the object of the invention is to produce a simple and eiiicient means whereby the initial stroke of a piston of an engine may be started by the impact of an explosive material which is ignited in a receptacle havingcommunicationwith the combustion-chamber of the en, gine.

More specifically, the invention consists in the provision of a starter for gas-engines comprising a shell adapted to contain an explosive material, such as powder, and which shell is, connected to and communicating with the cornbustion-chamber of an engine and having in one end of said shell a nipple adapted to receive a percussion-cap, against which a plug is adapted to be forced to explode the same, whereby the charge may be ignited and exploded for the purpose of starting the engine.

My invention consists, further, in various details of construction and arrangements of parts which will be hereinafter fully described and then'speciically dened in the appended claims. v

My invention is illustrated in the'accompanying drawings, in Which.-

Figure l is a sectional view through a portion of the cylinder of au engine and of my attachment. Fig. 2 is an enlarged detail sectionalzview of an explosive-tube which is attachedto the cylinder. Fig. 3 is a perspective View of the parts disassembled; and Fig. i is a longitudinal sectional View through a tube, showing a slight differentiation in the construction of the disk and plug. -f

Reference now being' had to the details of improved starter.

the drawings by letter," A designates the'cylinder of an explosive gas-engine, which may be of any construction, and one end of the cylinder has an aperture,I vas at A', which is threaded to receive the threaded end ofthe tubular shell B, forming the cylinder of my Said shell B is adapted to contain an explosive material, such as powder, (indicated by the dotSv B',) mdfhas its outer end externally threaded to receive a unionU: A disk D, having a shoulder-D bf suihcient diameter to snugly t into' the Outer end of said shell B, isprovided, and said disk D has a central aperture adapted to receive a nipple E, and the outer face of the-'diskAD is countersunken, as shown clearly in Fig. ZAof-4 the drawings, and the nipple E has an annular .shoulder E about its ,circumference adapted.

to bear against the outer face of said disk. The'nip'ple is centrally apertured, asat e., and

percussion cap e. having threaded circumference adapted to engage the threads on the inner face ofthe union C and a projecting portion F upon its ipner end adapted to contact with the cap and force the same against the end of the nipple with sufiicient force to cause the same to explode as the plug 'is screwed into the union.

In Fig.' 4 vof the drawings I have shown av slight moditicationof my invention, in which vthe disk D2 has its outer face'iiat instead of cap.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A device for starting engines comprising a cylindrical' portion adapted to contain a starting charge of an explosive material and fastened to and communicating with the explosion-chamber of an engine, a union mounted upon the threaded end of said cylinder, an apertured disk seated against the end of said cylinder and-Within the union, a hollow nipple carried by saiddisk, and va threaded plug IOO 7o its outer end is of sufficient size to receive a.

A yplug F is pr0vided,- v

' chamber of a gas-engine, adisk having-a portion thereof fitted within said cylinder and centrally apertured, the outer face of said disk being countersunken, an apertured nipple fitted into the aperture of said disk, an-

' internally-threaded union tted to the circumference of the cylinder, and a threaded plug fitted to the threads of said union and adapted to bear with suiiicient force against a'cap designed to be held upon said nipple, to cause the sameto explode, whereby the charge within said cylinder may be ignited, as set forth.

3. A starter for gas-engines comprising a cylinder adapted to be connected to and comshoulder engaging the outer face 'of said disk, u w

a union fitted to the threaded circumference of the cylinder, a plug adapted to screw into said union and to -bear with suioient force against a percussion-cap uponsaid nipple to 'cause the same to explode, whereby the explosive material within said cylinder may be ignited, as set forth.

In testimony .whereof I hereuntonafiix my signature in presence of two witnesses.

JOHN BRUCE MORRISON.
