ROTARY NGENE.
SPECIFICATION forming part of Letters Patent NO. 600,753, dated March 15, 1898. Application filed July 8, 1897. Serial No. 643,802. (No model.)
To whom it may concern:
Be it known that I, GUTIE H. TUTTLE, of Montgomery, in the county of Montgomery and State of Alabama, have invented a new and Improved Rotary Engine, of which the following is a full, clear, and exact description.
My invention relates to an improvement in rotary engines, and comprises a casing having a cylindrical chamber or cavity therein and a rotary disk of smaller diameter than the cavity, said disk having a projecting abutment with an incline upon one side and acting as a piston, and the casing having a slot receiving a sliding abutment, which acts also as a valve to cut off and admit the steam.
The invention also consists of certain details of construction,which will be hereinafter described and claimed.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar. charactersof reference indicate corresponding parts in all the views.
Figure 1 is a sectional elevation on the line 1 1 in Fig. 2. Fig. 2 is a section 011 the line 2 2 in Fig. 1. Fig. 3 is a top plan View of the engine complete. Fig. 4 is a side elevation of the plate forming one head of the cylinder. Fig. 5 is a section taken upon the line 5 5 of Fig. 4:. Fig. 6 is an elevation of the rotary disk with one of the projecting abutments. Fig. 7 is a plan view of the spring which is attached to the sliding abutment; and Fig. 8 is an elevation of the lower part of the sliding abutment, the last two figures showing the method of connecting thesetwo parts together.
The engine comprises two cylinders formed in one casing, which consists of the central web A, having a rim A projecting beyond the web at each side, forming a cylindrical casing the open end of which is inolosed by the cylinder-heads B. A shaft D is mounted in the center of this casing and carries two wheels or disks 0, each occupying one of the chambers formed in the casing. These wheels O are circular in outline and preferably are made with the outer rim projecting, as at 0 so as to fit the underside of a groove 1), formed in the heads B, and a similar groove'formed suitable screws.
in the central web A of the casing.
To opposite sides of the wheel or disk 0 are attached two abutments E. These abutments are provided with a packing'strip E to make a steam-tight contact with the outer periphcry of the cylindrical chamber. Upon one side they are provided with a cam or incline E, adapted to engage the sliding abutment to raise it as the abutment E passes the same. Preferably the abutmentE and cam or incline E are made separate from the disk and attached thereto by bolts.
The annular chamber 0, surrounding the disk 0, is of the same size at all points, except that on one side, and extending from the sliding abutment in a direction therefrom opposite the direction of rotation of the disk is a recess or upon its outer periphery to receive a flat spring J. This spring is secured at one end to the sliding abutment F by means of dovetail tongues J, fitting into similar grooves f in the lower end of the abutment F.
At its opposite end it is secured to the outer surface of the cylinder-chamber by means of This spring J is a springplate and is adapted to yield under the action of the cam or incline E, so as to force the spring into the recess a, in the cylinder. As the spring J rises the abutment F is raised, so that the piston-head formed by the abut- 8o ment E may pass under the same. The upper end of the plate F, forming the movable abutment, lies just below the steam-port G when the abutment is resting upon the surface of the disk O. As the abutment rises 8 5 under the influence of the incline E it closes the steam-port, thus cutting off the supply of steam. As soon as the piston-head E has passed the abutment F the latter will drop down under the influence of the spring-plate 0 J. This admits steam through the port G and behind the piston-head E.
The exhaustport islocated at I, being at an angle of about ninety degrees from the steam-port G. As before stated, two pistonheads or abutments E are attached to each of the disks 0, being attached at an angle of about ninety degrees upon opposite disksthat is, the abutment upon the disk upon one side alternates with the abutment upon the other disk, thus bringing one of the abutments or piston-heads into use at all times.
Through that portion of the circumference of the cylinder which is filled with live steam a strip Z) is placed upon both the head B and the central flange A. This strip is placed so as to be in close cont-act with the inner surface of the outer edge of the wheel or disk 0, as is clearly shown in Fig. 2. This construction makes a tighter joint than would otherwise be obtained. The spring-plate J is to be so proportioned and constructed that the pressure of the abutment F upon the disk shall be very slight, thus avoiding a large amount of friction ordinarily due to the use of such an abutment and also makes the same easy to raise under the influence of the incline E.
The steam-pipe H, delivering steam to the engine, is forked into two branches h, so as to deliver the steam to each side of the engme.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- A rotary engine comprising a cylinder having steam supply and exhaust ports and a radially-extendin g slot adapted to receive a movable abutment and extending across the supply-port, an abutment in said slot adapted to open said port when in its inner position, a curved fiat spring adapted to extend about a portion of the upper periphery of the cylinder-chamber and connected at one end to the cylinder and at the other end having fingers dovetailed into the inner end of the abutment, thereby forming a yielding or sliding connection with said abutment, the cylinder being provided with a peripheral recess adapted to receive said spring, and a rotating piston-disk having an abutment or head thereon having an incline adapted to raise a movable abutment.
