ROTARY ENGINE.

sracrrrcnrron forming part of Letters Patent is... 655,175, dated July 3'1, ieoo. Application filed November 16, 1899. Serial No. 737,185. (No model.)

To all whom/it may concern:

Be it known that I, CHARLES E. LINTON, a

citizen of the United States, residing at Saginaw, in the county of Saginawand State of Michigan, have invented certain new and useful Improvements. in Rotary Engines; and I do declare the following to be a full, clear, and exactdesc'ription of the invention, such as will enable others skilled in the art to which it appertains same, reference being had to the accompany.- ing drawings, and tothe letters and figures of reference, marked thereon, which form a part of this specification.

My invention is a rotary engine; and it consists of the combination, arrangement, and construction of the several parts whereby certain important advantages are'attained.

. In the drawings Ihave illustrated what may be termed a double pistn.,-:-.2'. e., a piston with two steam-chambers,whereby the engine has continuous pressureevia, one half live steam and the other half expansion, as hereinafter appears. I have also illustrated a reversible engine. It will be obvious that the piston can be made single; but when so made it will run a portion of the time on expansion entirely. It will also be seenthat the piston may also be provided withwthreeor, more steam chambers. This I, claim the right to do. i 1

In the drawings, Figure 1 is a vertical sec; tion on line w w of Fig. 3, but showing the entire casing. Fig. 2 is a section on line m w of Fig. 1. Fig. 1. Fig. 4 is a section 1. Fig. 5 is a section on line b b of Fig. 2 with the piston in different position. Fig. 6, is a section of the casing online a roof Fig.1. Fig. 7 is a section of the casing on line e z of Fig. 1. r r

A is the piston,and consists of a metal wheel carried on the shaft 13, journaled in the casing or may be suitably supported in any other manner and the sides of the casin g removed, as will hereinafter appear. The piston A is provided with two peripherical' grooves land 1, extending nearly around the piston and the proper distances apart and from the edges of the wheel. These grooves are the steamchambers' of the piston and, as stated, are not quite angular, the

piston lying between the ends of each groove respectively. These parts 2 and 2' are upon opposite sides of the circumference of the piston and are integral therewith and form, as will hereinafter appear, the piston-heads. These

parts

2 and 2 extend at right angles to the bottom of the grooves, but are provided ,on each side with the'slopingwalls 3, extending from the top of the heads to the bottom the proper slope.

6 is the casing of the piston A. The outer surface thereof maybe of any form, its inner surfacefitting the piston-wheel, and may be provided with steam or otherpacking, none being shown in the drawings.

'7 and 7 are gates of the width of the

grooves

2 and 2, and when in the grooves completely block the same and may be so constructed as to be steam-tight.

As the piston A revolves the sloping walls 3 of the heads will engage a gate and crowd it backward into a pocket 8 in the casing and as soon as the head. has passed the-gate it will descend,its descent being retarded by the sloping walls 3, which, as previously stated, are on each side of the head. A spring 9 may be placed in the pocket 8 to make the downward. movement of the gate more positive.

10 is the opening of the live-steam pipe, 11 a valve in thelive-steam port, and 12 and 12 the live-steam ports and extend from the valve 11 through the casing on each side of the middleithereof, respectively, and connect .withthe small channels tively, on the inner surface of the casing, but at the side of the piston-grooves 1 and 1' and not in communication therewith, except at certain periods of the revolution of the piston, through the elbow-channelsin the piston 15 and 16, which open into the grooves 1, and 15 and 16', which open into groove 1', through the openings land 5 in the sloping walls 3 at the side of the piston-heads 2 and 2'. The channel 13 extends from its connection with port 12 one-half the circumference of the easing. It will be seen that as the piston revolves the channel 15 of the piston will be in continuous connection with the channel 13 dur ing one-half of its revolution-4. c. during the time 15 ports with 13-and that steam will be cut off from the piston as soon as 15 has passed 13 and 13', respecthe end of the channel 13, and the piston will The groove 1 run on expansion until the head 2 has passed regulated from the outside of the engine, as

has exact duplicate connections to groove 1, and, its head 2 being on the opposite side of the piston from the head 2 when the groove 1 is cut off from taking steam, the groove 1 will commence to take IO steam from the channel 13 through the elbowchannel 16, and the engine will then be run by live steam in groove 1 and expansion in groove 1.

In order that the engine may be reversed, I

- construct the opposite side of the casing the same as the side just described-viz., with channel 13 connected with port 12, and provide the piston with elbow-channels 15 and 6', opening on opposite sides of the

heads

2 and 2 from the opening of channels 15 and 16, which will connect the grooves l and l with the port 12 through channel 13. 19 and 20 are the exhaust port and valve of this side of the engine.

22, 23, and 25 is an arrangement of levers connecting steam-valve 11 and exhaust-

port

20 and 20, whereby they may be adjusted so as to reverse the engine. 26 is a rack, in which the lever 25 may be locked when adjusted.

the groove at In the engine, as illustrated, I have shown a meansfor shortening the

grooves

13 and 13, so that lesssteam may be used-viz. the plug 35 extending from outside of the easing into any desired point and adapted to be inserted or withdrawn as desired. Any number of these plugs may be used as de is common.

As previously intimated, the side walls of the casing 6 may be discarded, thus leaving the sides of the piston exposed, as with the proper packing of the peripherical casing the steam will be confined in the piston-cham- I do not wish therefore to confine myself to the exact form or construction of the various parts illustrated and claim any change therein that may be suggested by mechanical skill.

Having thus I'claim as new, Patent, is-

1. In a rotary engine a casing for the same having on different'parts of its inner surface two or more channels a semicircumference or less in length, a metal wheel-piston having in its periphery one or more grooves extending nearly around the same, a head in each groove integral with the piston on the oppo site sides thereof, sloping walls in each groove on each side of the head-extending from the bottom of the groove and a short distance from the base of the head to the surdescribed my invention, what and desire to secure by Letters to connect with the channels in the casing as the piston revolves, steam-ports connected to the channels in the casing, and exhaust-ports connecting with the groove in the piston, substantially as set forth.

2. In a rotary engine, a piston-wheel having grooves forming the steam chambers, each groove having a head, the heads in different planes of the piston, a casing for the piston, two or more channels in the surface of the casing between the grooves of the piston and in communication withsteam-ports and in communication with channels in the piston connected with the piston-grooves and opening therein on each side of the pistonhead, whereby each groove of the piston will, during a portion of the revolution of the piston be in communication with the livesteam ports through the piston channels and easing channels with sliding gate to be actuated in and out substantially as set forth.

3. In a rotary engine having a piston-wheel having two or more grooves in its periphery forming steam-chambers, a casing for the piston having two or more small channels on its inner circumference between the piston grooves but not in communication therewith, each channel in communication with livesteam ports and during a portion of the revolution of the piston, in communication with the grooves of the piston with sliding gates in the casing to be actuated in and out substantially as set forth.

1. In a rotary engine, a piston having a steam-chamber extending nearly around the same formed by a groove in the piston, a head in the grooveintegral with the piston, a casing for the piston having two or more channels on its inner circumference not in direct communication with the steam-chamber but connected to live-steam ports, channels in the piston on each side of the head adapted to connect with the channels in the casing during part of the revolution of the piston and convey the steam to the steam-chamber just behind the piston-head, and a gate in the casing adapted to be actuated into the steamchamber and form a back stop for the steam, and means for throwing the gate in and out of the chamber substantially as set forth.
