PRIMING DEVICE.
APPLICATION FILED ALIG.9. 191s.

ATTORNEY JOHN C. GRAI", F HOLLISIEE, CALIFOLNIA.
PRIMING DEVICE,
Application filed August 9, 1916. Serial No. 114,!l49.
To all whom it may concern:
lie it known that T. .Tonzv 0. Gear, a. citi' men of the UnitedStates, re. 'rling at 'I-lollister, in the county of San Benito and State of California, have invented certain new and useful Im. u-ove1nents in Priming Devices, of which the following is a specification.
This invention relates to priming devices for internal combustion engines, and, while adapted particularly for use in connection with motor cycle engines, may also be used with. equal facility upon automobile or even stationary gas engines.
The primary object of the invention to provide a simple and improved means whereby an initial charge of combustible fluid may. be introdiiced to the engine cylinders with expediency and with little trouble, whereby the'rnotor may be quickly started.
Afurther object ofxthc invention is to proride a device of' this character for use in connection with motor cycles, the arrangek ment being such as will enable the rider or operator to mani 'iulatethe san'i positimi upon the saddle.
. A still further and particular object of the invention, is to provide a priming device of the above mentioned type which is of simple and inexpensive construction, which is composed of but few readil assembled parts, all so constructedand arranged as toprevent wear, breakage or derangement of the same, which is proof against becoming clogged or disorder-ml, and which will prove thoroughly ellioient in the attainment of the ends for which it is designed.
With these ohec-ts in view, together with o'tliersf'which wi 1 appear as-the description jareuuul-ls, 1hr invention resides in the novel formation, (illumination and arrangement of parts, all as will he described more fully lmre-in'a'lter llu trated in the drawings, and particularly pointed out in the claims. vThe invention will be best understood by retemr .e .to-the .accolnpimying, drawings, will 31* elevation of a. priming d rice .emistrueted in accordance with the invention, and illustrating the application of the same to a conventional type of motor ai Fig. 2 is an enlarged longitudina taken through the primer and Fig. 3 is a top plan view of the device.
1 section priming Specification of Letters Patent.
rammed Apr. 3', 191 v.
- Referring now more particularly to the dra wings, 4 indicates a fuel tank or reservoir of the motor cycle, 5 the engine cylin ders thereof, and "3 the priming cups for the cylinders. The engine in the present illustration is shown as being of the two-cylinder type,- however, it will be understood that the device may, with mine" alterations, be rel ad'ered applicable to engines of various types having one or more cylinders.
Disposed verticilly within. the fuel tanlr 4 is a tube 7, said tube proiectil'ig at its upper and lower ends beyond the upper and lower portions respectively of thextank. This tube may be solktlered or in any other preferred manner, secured within thetank. The lower protruding end of the tube is closed by-a head 8, the latter projecting be e froin his yend'the. said tube and is exteriorly threaded as shown for the reception of area 9. This cap carries ifiTifi ltrally arranged and dmvnwardly extending nipple 10,'to which secured the neck portion 11 of a three waywalve 12. The head. 8 is provided with a central bore 13 communicating with the' nipple 10 and is cut out or rounded at its inner endas at 14 to provide a seat for a suitable plunger 01 valve 15 contained with in the tube.
The valve has connected thereto extending pipes or duets 16, one leading to each of the priini 1;; cups 6 of the engine cylinders. The valve 12 may be controlled, by a suitable finger grip or plug member 17 as shown. l
The upper outwardly extending portion of the tube 7 is exteriorly threaded for the reception of a cap 18, the latter being dividedin its head with an aperture through Wh oh the plunger 15 extends. The upper protrudnig extremity of the plunger 15 has threaded thereon, lock nuts 19, between which a finger grip or handle ineml cr 20 is held. An expans on spring 21 ,en'oircles plunger 15, is seated at one end against the cap 18, and engages: atits opposite end with a cross pin 22 extendi-ngthrouggh the plunger inwardly from the lower end, thereof. The lower end of the plunger is; rounded as shown to correspond to the shape of the seat 14: in the head 8. Ports 23 are arranged in the wall of the tube 7 adjacent the lower end thereof, wherebythefl'uid fuel within 'the tank may have access to the interior of the said tube. l
In operation, the priming cup valves or oppositely other clos i'es, now showntin the present instance, a r opened, as well as the valve 12.
The plunger is then-lifted against the teqrgiono the spring 21, whereupon the 1 li id fiiel enters the passage 13, mpple 10 and passes through the valve and pipes 16 to the priming cups upon the cylinder. The cylinders are thus provided! w th fuel suflicient to enable the enginepto be started and the priming cups maythen be closed. The
release of the handle vof the primer automatically seats the plunger 15 upon the portion 14 of the-head 8, whereby further passage of fluid into the pipes will be prevented. The valve 12 may or may not be closed as desired, the plunger 15 forming a valve to to the primin cups.
From this escription, 1t is apparent that I have provided an extremely simple and yet thoroughly eflicient priming means for internal combustion engines. It' will be understood that additional branch pipes 16 may be used when itis desired to adapt the device to engines having three or more cylinders, while the pipes may be disconnected from the valve when the device is to be used with an engine of the one cylinder type.
- Ihave illustrated the pipes 16 in the present instance as leading to the priming cups of the engine cylinders, but it will be understood that these tubes may, if desired,
when the machine is left standing where unauthorized persons may tamper with the same.
revent vfurther admission of fluid While the above is a description of the obvious that various changes in minor de-.-
tails of construction, and arrangement of parts may be resorted to, if desired, without departin from the spirit of the invention, or excee ng the scope of the claims.
What is claimed 1s: V
1. In a priming device, the combination with an engine cylinder and the fuel'tank for a motorcycle, of a tube in the tank, the tube having apertures therein, a fuel connection between the engine cylinder and the tube said connection terminating adjacent to the apertures, a plunger in the tube of lesser diameter than the tube to leave a fluid'passage the plunger being adapted to normally close the mouth of the fuel connection, a spring normally seating the plunger, and finger pieces for unseating the.
plunglei '2. hecombination with a. fuel tank of a motorcycle and an engine cylinder, a tube in the tank, a fuel connection between the engine cylinder and the tube, said connection terminating at the tube within the tank, said tube having openings adjacent to the mouth I of said connection, a plunger adapted'to close the mouth of the connection, a spring on the plunger for holding it in such connection against the force of an explosion, finger pieces for unseating theplunger, and a. valve in the fuel connection for severing communication between the tube and the connection.
'In testimony whereof I afiix my signature in presence of two witnesses. i
