Specification of Letters Patent.

Patented Mar. 22, 1921.

Application filed March 27, 1920. Serial No. 369,289.

Gilmerton, in the county of Norfolk and State of Virginia, have invented a new and useful Heater, of which the following is a specification.

This invention relates to new and useful improvements in heaters, and more particularly to a novel form of portable heater especially designed for use in cold. weather, and for application to the manifolds of nternal combustion engines,to cause the 1ncoming gas to readily vaporiye.

An object of the invention 1s to prov de a device of this character having spring clamping means to permit the device be readily and easily clamped to the manifold of an internal combustion engine, regard less of the diameter thereof. j

A further object of the invention is to provide means for controlling the passage of heat from the casing of the heater to facilitate' the use of the heater with vertical and horizontal pipes. I

VVith the foregoingand other Ob]6 Cl3S 111 view whichwill appear asthedescription proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what claimed, w1thout departing from the spirit of the invention.

Referring to the draw1ngs:- D

Figure 1 illustrates a side elevatlonal view of an internal combustion engine, disclosing a device constructed in accordance with the present invention as applied thereto.

Fig. 2 illustrates a plan view of the heater, the clamping means being shown n section.

Fig. 3 illustrates an end elevational view of the heater.

Fig; 4 illustrates a transverse sectional view through the same, and 0 Fig. 5 illustrates a longitudinal sectional view through the casing.

Referring to the drawings in detail, the reference character 5 designates the usual feed pipe of a manifold of an internal com bustion engine, andthe reference character 6 designates-the usual distributlng pipe forming a part of the manifold, and to which the heater, forming the subject matter of the present invention is applied.

The heater includes generally the casing 7 which is formed preferably of sheetmetal, thesame being circular 'in cross section to faclhtate the handling of the device and to increase the efficiency thereof in applying the same, to the manifold of an engine.

One surface of the casing 7 is substantially as indicated at S, which flattened surface is provided with a plurality of spaced openings 9, and elongated slotted port ons 10, the slotted portions 10 providing guidways for the pins 11 carried by the slide 12, which is also provided with openings adapted to register with the openings 9 of the flattened surface of the casing. to permit the heat radiating from the heating element, to be hereinafter more fully at scribed, to pass upwardly therethrough.

These pins 11 are provided with heads 13 which engage the flattened surface of the casing adjacent to the walls of the slots 10, for securing the slide 12 in proper relation with the under flattened surface of the casing, to insure the operation of the slide. to accomplish the regulating function.

One extremity of the casing T is open, the edges thereof being turned in as at 14, which inturned edges embrace the shoulders 15 formed on the flange 16 of the inner cylinder or casing 17, which is formed preforably of sheet metal, and ofa diameter considerably less than the diameter of the casing 7 to provide the compartment 18 between the adjacent walls of the casing 17 and the casing 7.

Positioned in the compartment 18, is a suitable insulating material including preterably asbestos indicated at 19. the asbestos being shown as positloned between the vasing and the closed end wall of the casing 17, thus insulating the closed end of the casing 7, from the heat radiating from the heating element, which in operation is positioned in the inner casing 17. j 1

One end of the inner casing ,17 is open as at 20, to permit the heating element 21. to be inserted therein, and this heating element is preferably in the form of a metallic bar having a centralbore 22 to permit an iron to be inserted therein for convenience in handling. Openings 23 are formed in one of the side walls of the casing 17, which openings are in communication with the openings 9 of the outer casing, through the posite sides of the casing 7,

preferably of sheet metal of a resilient 'with' registering openings that register with suitable openings provided in the heat insulating material to permit the passage of heat through the end of the casing.

Operating adjacent the inner surface of the wall26, is a disk 29 which is secured to the wall 26 by means of the pivot pin 30, which passes through the wall 26 and has connection with the disk 29 substantially centrally thereof, so that movement of the pin 30 will cause a relative rotary move ment of the disk 29. Formed in the disk 29, at predetermined intervals, are a plurality of openings adapted to register with the openings formed in the cover to provide communication between the interior of the casing 17 and the atmosphere,that is, when the openings of the disk are moved in registry with the aforesaid openings. If it is desired to prevent the passage of heat through the openings in the cover, the disk 29 is moved to a position as indicated in Fig. 3v of the drawings.

The cover isalso provided with an ex tension 31 adapted to fit within the open end of the casing 7 so that when the bar 21 is positioned within the inner casing 17, the same will be prevented from displacement, by the cover. In order that the heater may be readily and easily applied to a manifold, clamping elements 32 are provided, which clamping elements are secured to opat points adjacent the lower edges thereof, the upper ends of the clamping elements being curved outwardly as at 33, and provided with openings 34 for the reception of a securing pin, not shown, which pin is to be employed should it be desired to apply the heater to a manifold, which is extremely small or one in which the diameter is considerably less than thedistance between the clamping elements 32.

These clamping elements 32 are formed quality, so that when the elements 32 are forced over a relatively large manifold, the clamping elements will expand and grip the manifold and hold the heater in position thereon, by such frictional contact.

Secured to the outer casing 7, at a point oppositeto the openings 9, is a handle 35, which may be of any suitable construction which will permit the positioning of the heater on a manifold, by grasping the handle and forcing the same into position.

In the operation of the device, the heating element 21 is subjected to heat until the same becomes sulliciently hot to accomplish the heating result, whereupon an iron is inserted within the bore 22 thereof, and the heating element positioned within the easing 17. if it is desired to heat both the vertical and horizontal pipes of :1 manifold as illustrated by Fig. 1 of the drawings, the disk 29 and slide 12 are moved so that the openings therein will register with the openings in the cover and easing 7, respectively, whereupon the heat will radiate from the casing and contact with the manifold pipes to the end that the gas passing therethrough is heated.

if only one of these pipes is to be heated, the slide or disk is regulated accordingly to control the passage of heat from the easing. llhen the manifold has been heated to a predetermined degree, the heater is removed by grasping the handle, and exerting a pull thereon to release the gripping elements thereof.

Having thus described the what I claim as new is l. A heater including an outer casing, an inner casing disposed within the outer casing, and having its side walls arranged in spaced relation with the outer casing, a heat insulating material supported between the casings, said casings having means of communication to the atmosphere, clamping means for clamping the heater to an object, a heating medium disposed within the inner casing, and cover for closing one end of the casing.

2. A heater including an outer casing, an inner casing supported within the outer casing and in spaced relation therewith, a heat insulating material disposed between the casings, said casings having means providing communication to the atmosphere, clamping means carried by the outer casing, a heating element disposed within the iimer casing, and having a central bore, and a cover for the outer casing.

3. A heater including an outer casing having a relatively flat surface forming a part thereof, said relatively flat surface having a plurality of openings formed therein, a sliding plate supported under the relatively flat surface and having openings adapted to register with the first mentioned openings, a cover positioned on the easing and having openings extending therethrough, means for controlling the passage of heat through the cover, clamping meahs carried by the casing, and a heating element. disposed within the casing.

4: A manifold heater including an outer casing, an inner casing positioned within invention,

the outer casing a heating element disposed within the inner casing, means it'or insulating the inner casing from the outer casing, said casings having means for providing communication therewith to the atmosphere, a heating element disposed within the inner casing, and means to permit the heater to he detachably applied to the manifold.

5. A manitold'heater including an outer casing and an inner casing, heat insulating means disposed between the casings, said casings having registering openings, a cover having openings providing communication between the interior of the inner casing and the atmosphere, means for regulating the 15 passage of heat through the openings, and means to permit the heater to be detachably connected to the manifold.

In testimony that I claim the foregoing as my own, I have hereto affixed my signa- 20 ture in the presence of two witnesses.
