PRIMING-CUP.
7 Specification of Letters Patent. Patented Blay 11, 1920.
Original application filed January 12, 1918, Serial No. 211,652. Divided and this application filed October 25, 1918, Serial No. 259,610. Renewed. August 30, 1919. Serial No. 320,821.
' priming cups for gas and other explosive engines comprising a body shell having a fluid receiving chamber constructed at its top to provide a fluid receiving opening and constructed at its bottom to provide a cooperating discharge opening, and a self-centering valve for effecting closure of the fluid 1 .discharge opening and loosely retained within the cup for compensating for lateral movement of the valve relatively to the body shell."
This application is a divisional application of my copending'application Serial No.
211,652, filed by me on the 12th day of January, 1918, and entitled Priming cup.
Further features and objects of the present invention will be more fully understood from the following description and the accompanying drawings, in which Figure 1 is a side elevation of a priming cu embodying my invention;
ig. 2 is a vertical central sectional elevation of Fig. 1;
Fig. 3 1s a vertical sectional central elevation; and
Fig; 4 is a detail top plan view of an element of the construction shown in Fig. 3.
Referring to the embodiment shown in 7 Figs. 1 and 2,'the body shell 1 is constructed interiorly' to provlde for the fluid receiving chamber 2 constructed at its top to receive gasolene or other priming fluid. The body shell 1 is provided at its lower end with the fluid discharging passage 4, preferably having a valve seat. The receiv ng chamberz2,
as shown, may be of an inner shell 7 suitably retained at its upperedge within the body shell 1 as by crimping or the like. Exteriorly, the body shell '1 is of the usual contour and may be provided with the threading 16, for threaded insertion within the shell of the cylinder of the explosive engine.
As shown, the valve 5 may be provided with the val e closure 2.2 a p e po 1 ing means ofthe valve ing moved upwardly to close the discharge opening 4 in sealing relation.
Means are provided for loosely mounting the valve stem 5 within the body shell 1 and in the particular embodiment shown in Figs. 1 and 2, such loosely mounting means comprises the internally threaded member 10 threadedly connected withthe external thread 13 on the valve stem 5, said member 10 being loosely retained within the inner shell 7 by means of suitable projections 11 respectively extending within suitable openings 12 in the inner shell 7. The valve stem 5 projects through the opening 14 upwardly of the body shell 1 and may be provided with suitable means for manipulating the valve stem 5, as by bending the valve stem 5 asindicated at 17. The opening 14 is relatively large as compared with the cross sectional area of the valve stem 5, .to' thereby permit passage of the gasolene or other priming fluid from the chamber 2 into the discharge passage of the priming cup.
Upon turning the valve stem 5 by means of the manipulating portion 17 to open the discharge opening 4, the valve 22'is moved downwardly and the member 1O is retained loosely relatively to the inner-shell 7. Upon turning the valve stem v5 to close the valve 22 against the valve seat 4, the member 10 by reason of its compensating lateral movement effects the self-centering of the valve in its I ternally threaded and adapted to be threadedly connected with the external threading 13 of the valve stem v5. The saddle 23 1s further provided with the suspending lugs 24 respectively loosely pro ecting through suitable openings in the body shell, as shown. Otherwise the modification shown in Figs. 3 and 4 corresponds similarly to the modification shown in Figs. 1 and 2 and like parts have been designated by like reference numbers. I I 1 7 By reason of the aforesaidloosely mountstcm relative to the casing of the priming cup, as will be apparent upon slightly opening the the valve when testing the cylinders of the engine by V opera-ting. the engine, in the usual manner, my invention serves as an indicator,whether or not the spark plugs of the respective cylinders of the engine are in operating condition, namely, in each of the cylinders in which the spark plug is in sparking order, the valve stem of its priming cup will be vibrated, whereas the cylinder whose spark plug is not in good sparking order,- the valve stem of its priming cup will be -q'uies cent.
=It will be noted that the aforesaid embodiments of my invention are readily manufactured by means of simple stamping machines or a simple lathe, and eliminates the relatively high expense and the matter-of skilled labor required in providing-theusual internally threaded, fixed valve closure for the-priming cup.
The self-centering characteristics of my invention obviates the necessity ofabsolute perfect fit in construction and in'assembling "and further aflords self adjustment 'upon "Wear ofthe movableparts or in the event ,ofbendingor otherwise misshaping any rt 'incident'to use. y r 7' Whereas I have described by inventionby reference to specific forms therjeoflit will -be' understood that many changes and modifications may be made without departing from the spirit of the invention as defined by the appended claims.
