UNITED STATES PATENT OFFICE LEWIS-D. NELSON, OF UNION CITY`, MICHIGAN, ASSIGNOR OF 'ONE-HALF TO ROBERT NEALE, OF UNION CITY, MICHIGAN.

AIR-HEATING ATTACHMENT FOR INTERNAL-COMBUSTION NGINS.

Specification of Letters Patent. l

Application filed September 1S, 1917. Serial No. 192,110.

To all whom it may concern:

Be it known that I, Lewis D. NELSON, a

` Citizen Qithe United seines, residing at Union City, Michigan, have invented Acertain new and useful Improvements in Air- Heating Attachments for Internal- Combustion Engines, of which the following is a specification. This invention relates to improvements in internal combustion engines.'v

The main objects 'of this invention are: First, to provide in an internal combustion engine an improved structure-in which the exhaist and :niet manifolds are .housed so that the inlet 'manifold isheated, the housing constituting an air heater for the, carbureter.

' Second,.tol provide a structure having these advantages which is adaptedto -be applied to automobile engines of well known type, such 'as the Ford, without materially changing the same and without the necessity. or tapping for securing the for drilling added, parts.

Furtherobjects, and objects relating to detailsfand economies of construction and operationfwill definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the oll'owingspecitication. The invention is clearly defined and pointed outl in the claims. Y y

A structure constituting a preferredembodiment of my invention is illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is a detail side elevation of the structure embodying the features of my invention, various parts being shown conventionally. l

Fig. II is a detail vertical transverse section on a line'cori'esponding to line 2-2 of .Fig I the rear section ot' the intake manifold pipe l extension reinovei..

Fig. Vl is an inside view of the removable seetnmbflhe intake pipe extension.

Fig. VII is a detail section through one ,of the housing valves on a line corresponding to line 7-7 of Fig. II.

In the drawing similar reference charac ters refer tx) similar partsthroughout the several views, and the sectional views are taken looking in thedirection of the little arrows at the ends ofthe section lines.

Referring to the drawing, 1 represents the body of an engine such as that employed in a Ford automobile,'thesam'e bein' shown mainlylin conventional form. 2 indicates the exhaust manifold and 3 the intake manifold thereof. The carburetor 4 is also shown conventionally.

The manifolds are secured by the clamp-` ing yokes 5 and the bolts 6. The bolts shown at 7 are the usual cylinder head bolts. The bolts 6 are bolts substituted vfor the clamping bolts commonlyemployed for securing the manifolds, the bolts 6 being exengine, as shown in Fig. I I with the top' wall lapping ii on the head. The top Wall is provided ivitii holes indicated at 17 adapted to receive the head bolts 7. dThe bottom wall of the housing has angular shoulders 18 adapted to engage the shoulders 19 of the engine body. By this arrangement of parts the housing is efectivelysecured b means of the head and the manifold clam lng bolts so that it is unnecessary to tap t e engine body or provide other securing means for the housing.

The housing has an intake pipe extensionA comprising part Q0 which is formed intgrally withv the body of the housing and a removable complementary section 20', the upper edge of which Ahas arib 21 corresponding to the 'ribs 418. The removable section of the housing and the main body of the housing are provided with' opposed ears 22 adapted to receive bolts whereby' the removable section is 'effectively `secured in place and at. the saine time nniy be removed'` to permit the convenient assembling anddisassembling of thehousing upon the engine.

'lhe housing is provided with ports 23 and 24 at its ends provided with valves 25. The valves are preferably connected by the vlink 26 so that they are simultaneously operated. The vali-'e operating rod 27 is con# nected to the rear valve, the rod being disposed through the instrument board 28 for4 convenience in manipulation. These valves are connected so that when one is opened the other is closed. As the carbureter pipe 29 is connect-ed at one end of the housing there is a comparatively short path to the pipe 29 for the air fromthe inlet valve at that end to the carbureter, and a long path from the other valve to the pipe 29, so that eiiective regulation of the heat is provided by manipulation of these valves.

I have not in the accompanying drawing attempted to maintain the relative proportions of the various parts as the same may n be varied to meet varios conditions which may exist in the adaptations. Further I have not attempted to illustrate the various adaptations that are possible. and contemplated by me as I believe the disclosure made vwill enable those skilled in the art. to which my invention relates to embody or ada ptl the same as may be desired. n

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

l. In an internal combustion engine, the combination with the engine body, of a carbureter, intake and exhaust manifolds, manifold securing yokes and bolts, the bolts being extended through the yokes to engage a housing, a manifold housing comprising front, end, top, and bottom walls embracing said manifolds, the top wall being lapped Aupon the top of the engine and provided upon the top of the engine and lprovided awith bolt openings through which the cap bolts of the engine are disposed, the front wall being provided with bolt openings through .which said manifold securing bolts are disposed, air inlets for said housing provided with valves connected for simultaneous operation, and an air intake pipe for .said carbureter' -connected to said housing nearer one of said inlets than the other.-

3. In an internal combustion engine, the combination with the engine body, of a carburetor, intake and exhaust manifolds, mani.- fold securing yokes and bolts, the bolts being extended through the yokes to engage a housing, a manifold Ahousing comprising front, end, topandbottom Walls, embracing said manifolds, the top wall being lapped upon the top of the engine and provided with bolt openings through which the cap bolts of the engineA are disposed, the front wall being provided with bolt openings through which said manifold securing bolts are disposed, saidhousing being provided with a tubular intake pipe extension. provided with a removable rear section, there .being opposed clampingears on said removable section and adjacent parts ofthe housing whereby the removable section is secured in place, and an air intake pipe for said carbureter connected to said housing.

4; In an internal combustion engine, the combination with the engine body, of a carbureter, intake and exhaust-manifolds, a, manifold .housing embracing said manifolds and secured to said engine body, said housing being provided with a tubular intake pipe extension provided with a removable rear section, there being opposed clamping cars on said removable section and adjacent parts of the housing, whereby the removable section is secured in place, and an intake pipe for -said carbureter connected to said housing.

In an internal combustion engine the combination with the engine body, of a carbureter, intake and-exhaust manifolds` a with a tubular intake pipe extension prof manifold housing embracing said manifolds vided with a removable rear section, there bei-ng opposed clamping ears on said .reinovable section and adjacent parts of the housing whereby the removable section is secured in place, air inlets for said housing provided' and secured to said engine body, said housing being,r provided with a tubular intake pipe extension provided with a removable rear section. mcans'for securing said removable section, and an intake pipe for said carburetor connected to said housing.

(i. In an internal combustion engine the coilnbination with the engine body, -of acarbureter', intake and exhaust manifolds, a manifold housing embracing. said manifolds, air inlets for said housing provided with valves connected for simultaneous operation so that one is opened as the other is closed, und an air intake pipe for said carbureter connected to said housing nearer one of said inlets than the other.

'i'. In an internal combustion engine the 130 vcombination with the engine body, of a ca-I'- hand and seal in the presence of two Witbureter, ilnt-ake and exhaust manifolds, a nesses.
