PROTECTIVE COVER.

Application filed April '15, 1925.

This invention relates to improvements for use upon a Ford engine and which contemplates the provision of a tubular member which is arranged transversely within a pocket provided centrally of the engine 'lock and which is adapted to receive the usual and ordinary carburetter throttle rod thercthrough and yet prevent the access of dirt and the like from entering the valve chests and better protect all parts of the engine as all dust, sand and extraneous matter which gets into the valve chest is washed into the crank case by the oil supplied to the valves.

Another object is the provision of means arranged within an opening in the cylinder block behind the elongated opening provided in the valve cover plate for completely enclosing the valve spring chamber in order that no cool air will seep or pass in and around the valve stems nor deposits of extraneous matter whereby the oil supplied to the valve stems from the crank case will in no way be contaminated or polluted whereby the correct lubricant may be applied to the valve springs and mechanism therefor and yet allow the heated air to favorably act upon such. mechanism to insure proper operation and easy starting the motor in general.

lVith the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claims.

In the drawing 2- Figure 1 is a horizontal section taken through a portion of the engine block and showing the relative position of the tubular member therein.

Figure 2 is a front elevation of the valve chest protector plate.

Figure 3 is a detail perspective of a modified form of my tubular member.

Figure 4 is an end elevation thereof.

Figure 5 is a vertical sectional view of the modification.

Referring to the drawing in detail, wherein like characters of reference denote correspondnng parts, the reference character indicates a Ford engine block which includes a conventional form of opening or a transversely disposed socket 11 arranged between cylinders 2 and 3 of the engine and which is adapted to receive therein and Serial N0. 23,408.

transversely thereof a carburettor throttle rod 12 which has its opposite ends connected to the end of the steering column throttle rod and the butterfly valve arm on the carburetter.

This opening or socket furtherincludes a restricted entranceopening 13 upon one end thereof as is well known in the usual and 14 that a space is left between the inner sides of the valve cover plates 15 and the corresponding sides of the block 10 and in order to completely close this space 1 pro.- vide a tubular member 17 which may be frustro-conicalin cross section and include an elongated end upon one end thereof to register the correspondingly shaped opening provided centrally of the valve cover'plate 15 and which has provided upon the elongated end of the tubular member 17 an outwardly extending plate or flange 18 which is riveted or otherwise secured to the inner side of the valve cover plate 1.5 and in regise trat-ion with the opening 16 provided there- The opposite end of this frustro-conical member 17 which includes outwardly and upwardly extending flange members 19. upon the outer sides thereof and which provide a pocket or the like in which is received a circular packing which is adapted to be forced against the inner side of the restricted entrance opening 13 within the opening or pocket 11 in order that drafts, dust and other extraneous matter will be preventedfrom entering the valve chest 14 and be allowed only to pass through the frustroconical member 17 As clearly illustrated in Figures 3, 4 and 5 I have illustrated a modified form of my invention and which includes a frustro-conical member 17 having an outwardly and upwardly extending annular flange 19 provided upon the smaller end thereof and which is adapted to receive a resilient packing or the like 20 as used in the preferred form of my invention. The opposite end of the frustro-conical member 17 includes an annular flange 18 provided thereon and which is correspondingly shaped with the elongated end and which further includes a slitted portion 21 which extends outwardly from the inner sides thereof and which are adapted to be bent outwardly in the manner as clearly illustrated in Figure l and in so doing secure this end of the lirustro-conical member 17 securely to the valve cover. plate 15 as clearly illustrated, in Figure 5 of the drawing.

It will thus be noted from the foregoing description and accompanying drawings that this invention provides a very useful and advantageous attachment for use upon Ford motors and which will prevent the accumulation ol? dust and other extraneous matter within the valve chest of the motor in order that the oil or the like contained therein will not be polluted or in any way contaminated by the dust and other extraneous matter which would materially intertore with the operation or the valves in so far as it would make the valves stick and prevent the proper lubrication of the valve stems within their bushings, not shown, as well as prevent the accumulation of grit between the lower end of the valve stems and the valve tappets in order that the valve heads will be properly seated within their seats.

The invention is susceptible of various changes in its form, proportions and minor details of construction, and the right is herein reserved to make such changes as properly fall within the scope oi the appended claims.

Having thus described my invention what is claimed is 1. A-protective cover for use upon internal combustion engines and the like comprising a frustro-conical member arranged within the transversely disposed opening provided centrally of the engine block, means for securing one end of the conical member to a valve plate and means for resiliently supporting the opposite end against the restricted entrance opening provided in the transversely disposed opening.

2. A protective cover 01 the character described having an annular flange provided upon one end thereof, a circular pocket provided upon the opposite end thereof, means for securing the annular flanged portion of the cover to a valve cover plate, and resilient packing means arranged within the pocket provided in the opposite end of the protective cover substantially as set forth.

A protective cover of the character describedhaving circular and elongated portions upon the opposite ends thereof, an annular flange provided upon the elongated end of the cover, a pocket provided upon the outer sides and adjacent the opposite end of the cover, a circular resilient packing arranged within the pocket and means included upon the annular flanged portion for securing the opposite end to the inner side of a valve cover plate for holding the same in registration with a correspondingly shaped opening provided centrally therein.

a. A frustro-conical shaped protective cover of the character described having an upwardly and outwardly extending annular flange portion provided adjacent the smaller end of the cover and providing a pocket therebetween, the opposite end of the cover being substantially elongated and including an annular flange upon the outer ends thereoi, and a plurality of slitted resilient members extending on the outer ends of the elongated ends and adapted to extend through a correspondingly shaped opening provided centrally within the valve cover plate and bent thereon for rigidly securing this end of the frustro-conical protective cover thereon.

In testimony whereof I aflix my signature.

JAMES BRYANT ROlVE.
