MANIFOLD-HEATER.

' Specification of Letters Patent.

Patented Nov. 9, 1929.

Application filed January 2, 1920. Serial No. 349,057.

To aZZw/Lmnc't may concern:

Be it known that I, Enwann BOWMAN, a citizen of the United States, residing at Dubuque, in the county of Dubuque and State of lowa, have invented a certain new and useful Improvement in lilanifold-Heaters. of which the follow ng is a specification.

This invention relates to an intake manifold heater for automobiles. While the drawings show such a device for a popular make of car now made in very large quantities, the irwention is not limited to that specific form of device shown.

The object of the invention is to provide a rum-electric manifold heater which can be readily applied to the manifold of an automobile and particularly to the specific car above referred to, which can be easily put in place and removed therefrom, which does its work well and is not liable to get out of order. The invention consists in mechanism capable of carrying out the foregoing objects, and also inmany features and details of construction which will be hereinafter more fully set forth in the specilication and claims.

deferring to the drawings in which like nume 'als represent the same parts through out the several views.

Figure l is a side view of the manifold side of the engine of an automobile, showing the mechanism of this invention in its preferred form applied. thereto.

Fig. 2 is a sectional detail view on the "line 2-2 of Fig. 1.

Fig. 8 is a perspective view, the parts constituting the mechanism of this inven tion separated one from'the other.

Broadly speaking, the invention consists in a portable oil heated lamp or furnace applied to the manifold of the engine in such a way that the heat generated by the lamp of the furnace has ready access to the pipes of the manifold. In Figs. 1 and 2, the de vice is shown applied to the manifold piping system 10 of the engine mechanism 12. It consists of an irregular shaped box or case it preferably but not necessarily having an inclined roof 16 leading to a large opening 18 giving access to the manifold pipes 10 of the engine. The face 30 of the box, which surrounds this opening 18, is in the particular case here illustrated provided with. integral ribs 20 which enter the vertical spaces usually found between the manifold pipes 10 so as to make a practically gas tight fit about the opening 18. Projecting from the upper portion of the box is a flange 22 having ears 24: through which are perforations 26 for securing devices such as pins 28 on standard clamps 29 of the automobile of the class described arranged to secure the device to the manifold side of the engine in any convenient manner. In the particular car for which the device is designed, these clamps are part of the engine equipment and are merely released long enough to apply the heater. Also projecting from the face 30 of the box in which is opening 18 and above that opening is a horizontal lug or flange 32 adapted as clearly shown in Fig. 2 to fit between adjacent pipes of the manifold and thus insure hot gases created in the box to pass through the opening 18 and pass the pipes 10.

The heating equipment of the box consists of some sort of wicking 34, adapted for impregnation with alcohol or the like, located in a receptacle 36 mounted on a drawer 38 slidable in and out of the box from the left as viewed in Fig. 2. The drawer carries a closure plate or door d0 interfitting with the box as shown in Fig. 2. The drawer is manipulated by a handle 42 and is locked in place by some suitable form of spring catch, as for instance the spring 4d engaging the lower edge of plate 30 at L6 as shown and adjustable with reference to the drawer by the screw 48. Access of air to the device is provided by perforations in the bottom plate 38 and by a notch or other suitable opening 52 in closure member 40.

The stove mechanism 3d36 is provided with a suitable removable cap 54: adapted to be placed over the contents of the cup 36 to extinguish the flame from wick 84 in the usual manner with alcohol lamps and to retain the fuel material therein without evaporation when the device is not in use.

In the operation of the device, the parts shown in Fig. 4 are sold commercially in assembled form. The purchaser, on obtaining one of these equipments, takes hold of handle 42 and pulls it to the left as shown in Fig. 2, thus automatically releasing spring 44 and bringing the parts to the position of Fig. 3. After removing the cap 54 and filling the cup 36 with alcohol or other suitable material, the operator lights it. either before replacing the drawer or after, practically or wholly replacing it by inserting a match through perforation i0.

The device is allowed to burn in the position shown in Fig. 2 until the manifold mechanism 10 is sufiiciently warm, whereupon the operator removes the drgwver, extinguishes the flame by putting the cap--54 over chamber .36, thenreplaces the drawer and leaves the parts in assembled position until such time asit is necessary'to again heat the manifold. In actual construction, the mechanism is made of such size and pr0- portion that the chamber 36 will contain suflicient liquid fora substantial number of manifold heatings before it is again necessary to refill the chamber 36.

Having thus des ;ribed my invention what I] claim as new and desire to secure by Letters Patent, is

'1; In mechanism of the class described, a box having a substantially straight side adapted to be applied broadside to a manifold, said side having an opening adapted to be applied in proximity to the manifold of an engine, means for attaching the box to the manifold, irregular interfitting ridges on the unperforated portion of that face of the box adjacent to the manifold conforming to the irregularities of the engine manifold, and means for temporarily generating heat inside the box, and delivering it through said opening.

2. In mechanism of the "class described, a box having an opening adapted to lead to an'engine manifold, a drawer for said box removable therefrom and alamp carried by said drawer adapted, when lighted, to deliver heat through said opening, to the manifold, there being suitable draft openings through the drawer adjacent to the lamp, and a latch mechanism for holding the drawer in closed position.

,3, In mechanism of the class described, a box having a drawer in its bottom, a lamp carried by the drawer and removable with itfrom the box, means for detachably securing the drawer in place, an inclined roof for said box leading from the side, of the box through which the drawer is removed upward to the other side of the box, there being a port in the last mentioned side of the box through which heat given off by the lamp may pass to an engine manifold, and means on said last mentioned side of the box for securing it to a manifold, for the purpose set forth.

4. In mechanism of the class described, a box having a drawer in its bottom, a lamp carried by the drawer and removable with it from the box, means for detachably securing the drawer in place, an inclined roof for said box leading from the side of the box through which the drawer is removedupward to the other side of the box, there being a port in the last mentioned side of the box through which heat given off by the lamp may pass to an engine manifold, means on said last mentioned side of the box for securing it to a manifold, and a. deflecting plate 32 at the top of the opening leading to the manifold adapted to enter the manifold and forcegases from the device to pass entirely through the manifold, for the purposes set forth.

In witness whereof, I have hereunto sub-- scribed my name in the presence of two witnesses.

EDWARD BOWMAN.
