Specification of Letters Patent.

Patented June a, 192(1).

Application filed July 18, 1919. Serial No. 311,709.

To all whom it may concern:

Be it known that I, GEORGE C. SHINN, residing at Vancouver, in the county of Clarke and State of Washington, have invented new and useful Improvements in Heaters for Intake-Manifolds, of which the following is a specification.

This invention comprehends the provision of means for initially heating the intake manifold of a gas engine to facilitate startthe motor as the fuel is heated prior a single length of material and utilized from means employed for associating the intake manifold with the exhaust manifold, for holding the ends of the material in a position to form the casing.

The nature and advantages of the invention will be better understood when the following detail description is taken in connection with the accompanying drawings, the

invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this specification, like numerals of reference indicate similar parts in the several views and wherein:

Figure 1 is a side elevation of a casing constructed in accordance with the invention, showing the same arranged upon the intake manifold.

' Fig. 2 is a vertical sectional view taken on line 2-2 of Fig; 1. i i

Fig. 3 is a transverse sectional view taken on line 3-3 of Fig. 1.

Fig. 4 is a detail section taken on the line 4--4 of Fig. 1.

Fig.5 is a view of the blank from which the casing is formed.

Fig. 6 is a view of the torch.

Before entering into a detail description, of what is herein shown, I desire to have it understood that the casing is formed from a single blank of material, which may vary in shape and size for application to any make or design of motor.

In this specific embodiment of the invention an elongated blank of material is folded transversely at a point between the ends thereof to provide the front and rear walls 10 and 11 respectively of the casing. As

shown in Fig. 5 the blank of material is formed with an extension 12 projecting from one side of the material adjacent one end thereof. In the formation of the casing, this extension is carried by the rear wall 11. and 1s adapted to be bent around the front wall 10 to form the one sidewall of the cas ng. This side wall terminates short of the lower end of the casing to define an open- 1ng orpassage 1 1 for that part of the intake manifold connected to the. carbureter. As shown in this instance, the opposite side of the casing is normally closed by means of a door 15, also formed from a piece of metal and given a substantially U-shaped configuration in cross section. The parallel be swung to the position illustrated in Fig. 1 when it is necessary to have access to the casing; p

Upon reference to Fig. 1 of the drawings 1t will be noted that-when thedevice is in place the intake manifold is arranged between the front and rear walls 10 and IL respectively, the casing being designed to completely envelop the intake manifold or substantially so. The front wall 10 adjacent its upper end is curved as at 15 in the direction of the rear wall to accommodate the pipe A, while the free ends of the material from which the casing is formed are disposed in parallelism and in contacting engagement' to each other. These ends are then positioned beneath the clamps D utilized for associating the intake manifold with the exhaust manifold of the engine. In this manner, the ends of the material are maintained in proper position to form the casing. In practice, the door 15 is opened and arranged in the position disclosed in Fig. 1, to permit a torch 18 carried by one end of a wire rod 19 to be positioned within the casing. The torch 18 is of course saturated with gasolene or the like, and after the torch has been ignited, the door 15 is swun to a closed position. Consequently, the intake manifold is heated in short order by the flame of the torch, prior to starting the motor, so that when it is desired to start the with a sleeve of asbestos which surrounds motor, the intake manifold will be hot enough to heat the fuel passing therethrough to facilitate starting of the motor. The torch burns out" in' a few minutes after which the elements 19 are removed from the cas that portion of the intake manifold passing through said opening.

While I have shown and described What I consider the preferred embodiment of the invention, I desire to have it understood that I do not limit myself to the construction,

shown and described, inasmuch as such changes may be resorted to when desired as fall within the scope of what is claimed.

Having thus described my invention what I claim as new is:

1 The combination with an intake manifold and an exhaust manifold of an engine, and means for securing said manifolds together, of a casing formed from a single blank of material and designed to envelop said'intake manifold, and the free ends of said material from which the casing is formed being arranged in parallelism and held associated by said means utilized for securing said manifolds together.

2. A casing of the character described comprising a single blank of material folded between its ends to provide afront and rear wall of the ,casing, and an extension projecting from, one side of the blank andfolded to provide one side wall of the casing, a door pivotally mounted upon the front and rear Walls and designed to embrace the opposite side edges of said walls, said front the straight wall and arranged to embrace the adjacent edge of each of the walls of said heater,and a closure pivoted at its lower end and designed to embrace the opposite edges of said walls as described.

4. A heater of the character described comprising a length of material bent into substantially U-shaped formation, one wall of the heater being perfectly straight, the opposite wall being curved in the direction of'the straight wall and terminating to lie in parallelism with the straight wall, contacting the latter, oppositely curved projections formed on one side of the heater and projecting from the respective walls thereof, an extension projecting from the straight wall and designed to embrace the adjacent edge of the other wall, a substantially U- shaped closure pivoted, on said heater and arranged toembrace the opposite edges of "the walls for the purpose specified.

In testimony whereof I afiix my signature.

GEORGE C. SHINN.
