Patented May 12, 1931 UNITED STATES PATENT OFFICE WILLIAM E. HOFFMAN, LOS ANGELES, CALIFORNIA Application filed May '28,
This invention relates to compressors, and it has for its broad object to provide a compressor which has the compressor and internal combustion drive engine combined in one block.
An object of the invention to provide a method of converting an internal combustion engine into a combination engine and compressor.
Another object of my invention is to provide a method of converting an internal combustion e'ngine into a compressor,
A further object of the invention is to provide a compressor which will not pump when there is a predetermined pressure on the pressure-side thereof.
Other objects and advantages of the invention will be made evident hereinafter.
. Referringvto the drawings in which I illustrate a preferred form of my invention:
Fig.-=:"1 is an elevational view partly se'ctioned.
Fig. 2 is an enlarged cross section through the upper part of a compressor-cylinder of the invention, this view being taken as indicated by the line 2-2 of Fig. 1.
Fig. 3 is a similar section but is taken on the line 3--3 of Fig. 1.
Fig. 4 is a horizontal section taken as indicated by the line 44 of Fig. 2.
' The form of the invention shown in the drawing is embodied in a motor having a motor body 10 of which a block 11 is a part. The motor body 10 provides a plurality of cylinders 12. The engine shown is a Ford motor, and the block 11 is provided with four cylinders l2.- The two central cylinders are power-cylinders and will hereinafter be recylinders are compressor-cylinders and will hereinafter be referred to by the numeral 14.
Operating in each of the cylinders 13 and 14 is a piston 15 having a connecting-rod 16 connected thereto. The lower ends of the connecting-rods 16 are journaled on a crank-shaft 17 The crank-shaft 17 is supported by main bearings 18. Secured to the top of the block 11, and forming a part of the motor body 10, is a head part 20 which defines the upper .wall of the cylinders 12 and provides compression-- ferred to by the numeral 13, and the two end 1927. serialno. 194,994.
spaces or chambers 21 above each of the pistons; The power-cylinders 13 have valve mechanism consisting of valves 23 which are operated by a cam-shaft 24, and associated mechanism for operating these parts. This construction is not a part of the invention and is at the present time part of the prior 7 art. Each powercylinder 13 is provided with a spark-plug 25 which is located in the compression-spaces thereof.
My invention as illustrated best in Figs. 2 and 3 provides an insert-member '30, one of which is placed in. each compression-spaces 21 of the compressor-cylinders 14. The insert-members 30 are adapted to completely fill the compression-spaces so that when the piston reaches the upper end of its stroke therewill be no clearance above it. It should be understood that the less the clearance at the upper end of the cylinder between the head of the cylinder and the piston, the greater will be the efliciency of the com: pressor. The insert-members 30 are each secured in place by a fixture 31 which is extended through the ordinary spark-plug port of the motor, as indicated by the numeral 32.
' Secured to each fixture 31 is, an exhaust-pipe 33. Each member 30 is provided with an 1 exhaust-valve 34 which closes an exhaustport 35 in the central part of each insertmember. The exhaust-valve 34 of each insert-member 30 is resiliently retained against a seat by means of a spring 36 which is placed in a socket of a plug 37, between a guide 38 of the valve 34 and the bottom of the socket. When the piston ofa compressorcylinder is moved upward, the exhaust-valve 34 thereof is unseated so that the port 35 is connected to a passage 40, this passage 40 connecting to the fixture 31 and consequently to the exhaust-pipe 33.
i As illustrated in "Fig. 1 each power-cylinder 13 is provided with a valve 43. This valve 43 is the ordinary-intake-valve of the engine and closes an ordinary intake-port 44 thereof communicating with an ordinary intake ma 'fold 44a. This valve 43, however, is not cam-operated but is held tightly seated by a resilient means in the form of a coilspring 45.
Each compressor-cylinder 14 has a port 47 which is ordinarily the exhaust-port of this particular cylinder. In my invention I utilize this port as an intake and pressure-relief means and provide an intake-valve 48 for closing this port. -'The intake-valve 48 when seated closes a passage 49, which is connected to the upper part of one of the compressorcylinders 14, from the atmosphere. A resilient means in the form of a Weak spring 50 is provided for resiliently seating the valve 48. During the down stroke of a piston in a compressor-cylinder the suction created opens the intake-valve 48 and draws air thereinto.
As shown best in Figs. 1 and 3, the lower end of each of the intake-valves 48 of the compressor-cylinders engages a rod 52 which extends through a nut 53 screwed into the upper end of a tappet-guide 54 of the engine. The rod 52 is provided with a piston 55 which is adapted to operate in the tappet-guide 54. Between the piston 55 and a lower face of the nut 53 is a spring 56. The lower end of this tappet-guide 54 is closed by a nut 57 having a passage 58 formed therethrough. Connected to the nut 57 and in communication with the passage 58 is a pressure-line 59.
' The pressure-line 59 extends from a pressuresource or from where they pressure in the exhaust-line 33 may be stored. As an example, the pressure-line 59 may be extended to a compressor air-reservoir or may extend to a pressure-operated diaphragm.
The operation of this part of the invention is as follows: I
The pressure which is produced by the compressor is transferred through the pressureline 59 to the tappet-guide 54 and upward against the piston 55. Nhen this pressure reaches a predetermined amount it is suflicient to lift the intake-valve 48 and to connect the passage 49 with the atmosphere. It will be seen that the compressor will then pump into the atmosphere and the air-reservoir or the pressure-side of the compressor will not be overloaded. In my invention I provide an intake and pressure-relief means of this character on both of the compressor-cylinders 14. In certain uses of the compressor it is not necessary to do this, but is sutficient to provide only one of the compressor-cylinders with a means of this character.
As previously explained, the engine shown is a Ford engine and has four cylinders. I convert two of these cylinders into compressor-cylinders and utilize the other two for power. The two central cylinders are utilized for power because of the fact that the explosion order in the different cylinders is 1, 2, 4 and 3. The Ford engine is converted from an engine which has a power-stroke twice a revolution to an engine having a power-stroke only once every revolution. It will, of course, be understood that my invention is not limited to a Ford motor but may be embodied in any motor regardless of the number of cylinders or regardless of the design.
The important features of the invention have been pointed out in the foregoing description, but as a rsum they will be briefly pointed out. In the first place, the invention provides a combined engine and compressor] which is embodied in the same block and which utilizes but a single crank-shaft. compressor-cylinders are readily adapted to the purpose of being utilized as a compression-means by a simple conversion, which consists of installing the insert-member, the exhaust-means, and the intake-means.

A compressor device, including: a combustion motor of the character described; and means equipping said motor for compressor utility, said means including intake and discharge means associated with a cylinder of said motor for intake and discharge of a fluid medium and an insert-member positioned against the upper wall of the compression space of said cylinder for reducing the volume of said compression space.
In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 21st day of May, 1927.
WILLIAM E. HOFFMAN.
