AIIt HEIhTER FOR CARBURETEES,

anaemic.

Application filed March 17, 1916, Serial No. @353.

To all whom it may concern:

Be it known that We, WIIJJAM SHAKE- srnARn, Jr., and WILLIAM SCHMID, citizens of the United States, residing in the city and county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Air-Heaters for Carbureters, of which the following is a specification.

This invention relatesto iinprovements'in air heaters ior carbureters.

The main objects of this invention are tov provide an improved air heater for carbureters which may be conveniently applied to the exhaust pipe of an internal combustion engine in the desired position thereon and one to which the air conduit of the air carbureter 1s convenlently connected..

Further objects, and objects relating to,

structural details, will definitely appear from the detailed description to follow.

We accomplish the objects of our invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims,

A structure which is a preferred embodiment of our invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is a side view of the structure embodying the features of our invention, the parts being shown mainly in conventional form.

Fig. 11 is an enlarged detail section on a line corresponding to line 2-2 of Fig. I.

Fig. H1 is an inside perspective view.

In the drawings similar reference numerals refer to similar parts throughout the several views.

Referring to the drawing, 1 represents an internal combustion engine, 2 the exhaust pipe thereof, 3 the carburetor and 4: the hot air conduit of the carburetor. These parts are all shown in conventional form as Specification of Letters .atent.

a shouldered ofiset 11 on the opposite side, the offset having a slot 12 in its top. A. pin

13 is disposed'adjacent the opening so that it projects into the collar 9 constitutmg a locating stop for the conduit l. The collar is perforated to receive the pin 14, the perforations in the collar and conduit being disposed so that they register when the conduit abuts the pin 13.

The clamping or retaining strap 15 is provided with a series of perforations 16 at one end, its perforated end being arranged through the opening 10 engaged with the pin 13 which is disposed adjacent thereto. The hood is provided with a boss 17 to properly support the strap'in engagement with the pm. At its other end the strap 15 is provided with a loop 18 having a perforation 19 in its bight to receive the clamping bolt 20 which is arranged through the slot 12 in the offset.

The nut 21 is arranged in a loop of the strap tocoact with the bolt, the head of which is slotted to receive a screw driver so that by turnin the bolt the strap may be tightened or c amped upon the exhaust pipe. This provides a very convenient and secure means for attaching the hood tothe pipe and one which permits its being attached in positions which are not conveniently accessible and would preclude the possibility of attaching hoods by the means ordinarily employed.

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

1. In a structure of the class described, the combination of a hood having a curved side wall and end walls having V-shaped recesses adapted to receive" a pipe, the side wall having an attachin collar for an air conduit and a slotted 0 set atone side of said collar and an opening at the other side, a pin disposed adjacent said opening, a strap having a series of pin engaging perforations at one end disposed through said side wall opening and engaged with said pin, the other end of the said stra provided with a loop having a per oration therein, and a bolt disposed through said being slot in said hood ofi'set and said perforation in said strap loop, there being a nut disposed within said loop to coactwith said bolt.

2.. In a structure of the class. described,

the combination of a hood adapted to embrace the side of a pipe and having a conduit attaching collar and an oiiset at one side and an opening at the other, a pin disposed adjacent said openin, gm a strap having a series of pin engaging perforations at one end disposed through said wall opening and engaged with said pin, the other end of the said strap being provided with a loop having a perforation therein, and a bolt disposed through said ofi'set and said perforation in said strap loop, there being a nut lisposed within said loop to coact with said olt.

in a structure of the class described, the combination of a hood adapted to embrace the side of a pipe and having an opening at one side and a pin disposed acent said opening, a strap having a perforation at one end disposed through said opening and engaged with said pin, the other end of the said strap being provided with a loop having a perforation therein, and a bolt disposed through said hood and said perforation in said. strap loop, there being a nut disposed within said loop to coact with said bolt. 7

l. Ina structure of the class described, the combination of a hood having a side wall and end walls recessed to receive an exhaust pipe, the side wall having an attaching collar for an air conduit and an offset at one side of said collar and an opening at the other side, a pin disposed adjacent said opening, a strap having a series of pin engaging perforations at one end disposed through said side wall opening and engaged with said pin, the other end of said strap being provided with a nut and a bolt disposed through said ofi'set to engage said nut.

5. In a structure of the class described,

the combination of a hood adapted to em- 7 brace the side of a pipe and having an opening at one side and a pin disposed adjacent said opening, a strap having a series of pin engaging perforations at one and disposed through said opening and engaged with said pin,-and a bolt carried by said hood and operatively connected to the other end of said strap for clamping the strap upon the pipe.

8. in a structure of the class described, the combination of a hood adapted to embrace the side of a pipe and provided with a strap pin at one side, a strap having pin engaging perforations at one end engaging with said pin, and a bolt carried by said hood and operatively connected to the other end of said strap for clamping the strap on the pipe.

7. in a structure of the class described, the combination with the exhaust pipe of an naacmo internal combustion engine and a carburetor air conduit, of a hood adapted to embrace the side of the exhaust pipe and having an attaching collar for the air conduit and an effect at one side and an opening at the other side, a pin disposed adjacent said opening, a strap having a pin engaging perforation at one end disposed through said opening and engaged with said pin, and a perforation at one end dispcsedthroughsaid opening and engaged with said pin, and a bolt disposed through said hood and operatively connected to said strap for clamping it upon the pipe.

9. In a structure of the class described, the combination with the exhaust pipe of an internal combustion engine and a carburetor air conduit, of a hood adapted to embrace the side of the exhaust pipe and having an attaching collar for the air conduit and an opening at one side, a pin disposed adjacent said opening, a strap having a perforation at one end disposed through said opening and engaged with said pin, and a bolt disposed through said hood and operatively -connected to said strap for clamping it upon the pipe.

10. In a structure of the class described, the combination with the exhaust pipe of an internal combustion engine and a carburetor air conduit, of a hood adapted to embrace the side of the exhaust pipe and adapted to receive the air conduit and having an opening at one side and a pin adjacent said opening, a strap having pin engaging perforations at one end disposed through said opening and engaged with said pin, and 'a bolt disposed through said hood and operatively connected to the other end of said strap for clamping the strap upon the pipe.

In witness whereof, we have hereunto set our hands and seals in the presence of two witnesses.
