To all whom it may concern: 7
Be it known that I, IRVIN S. CREAMER, a citizen of the United States, residing at Pleasant Hall, in the county of Franklin and State of Pennsylvania, have vinvented certain new and useful Improvements in Priming Devices, of which the following is a specification. a
The object of my inventionis to provide a priming device which can be constructed as an attachment to a spark plug to introduce an explosive charge or a volatile fluid into the explosion chamber in proximity to the sparking terminal or may be connected with the cylinder as a part separate and distinct from any connection with the. spark plug.
A further object is to so construct the priming device that the priming cup may be filled with a volatile liquid and. so long as the piston in the cylinder to which the device is connected is on its up or compression stroke no effect is noticeable and the liquid in the priming cup is not disturbed, but immediately the piston starts on its down or suction stroke the liquid in the priming cup is taken into the explosion chambel. of the cylinder;
WVith other objects in view which will be referred to, my invention consists in the peculiar combination and novel arrangement of the parts, such as will be hereinafter more fully described. in connection with the accompanying drawing and more particularly pointed out in the appended claims. In the drawing Figure 1 is a vertical sectional view through the upper part of a cylinder showing in elevation a spark plug with my in-' .vention applied thereto.
Fig. 2 is a view similar to Fig ,1 with parts in section to more clearly illustrate the construction and connectionof the priming device:
Fig. 3 is a vertical sectional view through the upper part of a cylinder illustrating theuse of my invention as a priming device parse.

In. thedisclosure in Figs. 1' and 2. the
Patented llllay 5L5, iltill't'.
has the usual spark plug opening 3, and the spark plug 4 is screwed into this opening. This spark plug is, in the main, of standard construction and design, itbeing provided with a central electrode 5 and a branch elecirodg 6 which are surrounded by the chamer V An arm 8 is formed to extend at an angle from one side of the case of the spark plug t and this arm is bored diagonally as at 9, the bore being'placed to extend from the end of the arm near one side thereof to communicate with the chamber 7. The end of the arm 8 is reduced and is provided with 'tents: and purposes the arm 8' valvecasing 11 and cup 13 are one continuous structure.
An opening 14 is provided through the bottom of the priming cup l3'and a needle valve 15 is mounted in the valve .casingin a position to control the opening 14, this .va
ve being held normally in a closed positio'nb a spring 16'1nounted around the stem tiereof and of the arm 8. a The opening in the valve casing 11 to re ceive'the valve is a bore formed lohgitudivnally from end to end and at its'outer endv communicates with the opening 14:.tl 11'O1lgl1 the bottom of the priming cup or liquid cup 13. By'reason ofthe fact that th outer 'end of the opening 9 through the arm-8 is oiiset to one side, this passage '9 does not strike. the bore through the valve casing, but rather the end of the arm 8 adjacent the bore presents a smooth, flat surface against which the spring 16 bears and to establish communication between the passage 9 and the bore of the valve casing a duct 17, as better shown inFig. a, is provided in the valve casing to extend from the bore thereof to a point to establish communication with the passage 9 of the arm 8.
The use of the device is as follows, the spar: plug set up as disclosed in Figs. 1 and 2 is connected through the cylinder to extend into the explosive chamber is-described. A liquid, of a high specific gravity is placed in the priming cup and it the engine be then with the piston on the up orcompression stroke, this compression is added to the bearing against the end tension of the spring 16 to hold the valve 15 closed within the opening 11 and no liq- .uid is permitted to'pass down. into the chamber but immediately the piston starts on ts intake "or suction stroke the pressure against the valve 15 is removed and a suction is created up through the chamber 7 v is shown in perspective,
and the passages connected therewith to unseat the valve 15 from its closure within the opening ll,'thus permitting. the liquid in the priming cup 13 to flow down through thisopening 11 into the valve casing 11 and thence through duct 17 and passage 9 to the chamber 7 of the spark plug. from which it passes to the explosive chamber 2 of the engine. As thedown stroke of the piston continues the liquid is exhausted from the cup 13 'and air is takenin through the line of passages, the opening of which is controlled by the valve 15, however, under some cir cumstances, it may be found desirable and even necessary to introduce air through the valve casing at the same time thatthe volatile liquid is being supplied therethrough and under such circumstances a passage 18 is provided through the side of the valve casing 11 to communicate with the opening through the center thereof, also under certain circumstances it may be found desirable to providea passage 19 which establishes communication direct from the passage 9 to the explosive chamber 2 of the engine. I
It will be understoodthat the electrical connection will be made with this plug in the usual manner, the one wire being connected by a binding nut 20 with the spark plug and the second wire of the circuit groundedyupon the, engine structure. The usualpr'itning device will be connected in this circuit and the wires are lead to a magneto or other suitable source of current ppl.
' Infthe disclosure in Fig. 3 where the priming device is constructed to be used independently of the spark plug, the cylinder 1' is provided with a screw-threaded bore 21 into which is screwed the tube which is preferably bent as shown so that the upper end extends in a vertical direction, and a passage 23 is formed through the cylinder of the engine to establish communication between the tube 2'2 and the explosive chamber 2. A coupling member 24 which corresponds to the arm 8 in the disclosure in Figs. 1 and 2. is screwed into the upper end ofthe tube '22 and at its free end has a screw-threaded portion 10 to receive the valve casing 11 which is identical with that disclosed in Figs. 1 and 2 and the remaining parts also are like -unto those in this disclosure, therefore, these parts will not be described.
the detail construction' h reof audit will be 1 gagement with said In Fig. 5 the coupling member' 24; to'better' disclose;v
.the tube 22 and the duct 17 from the bore of the valve casing. The use and operation of the structure disclosed in Fig. 3 are identical with the operation as above set forth, the one-difference being that in this adaptation the explosive mixture is supplied to the explosive chamber at a point away from the spark plug, whereas, with the structure shown in Figs. 1 and 2 the explosive mixture is discharged into the explosive chamber directly at the sparking terminal.
From theforegoing, it will be seen that I have provided a priming device with which an explosive mixture is supplied to the cylinder ofthe engine and all possibility of the charge or any part thereof being forced backthrough the priming device by the compression stroke of the piston is absolutely precludedlVhile I have herein shown and described substantially but one form of my invention, itwill be understood that slight changes might be made in the form and arrangement of the parts without'departing fromthe spirit and scope of my invention, and hence I do not wish to be cept for such limitations as the claims may import.
