Specification of Letters Patent, estimation filed March 22, 1906. h M1 No. 807,480.

. Patented Oct. so, 1906.

To all whom it mag concern:

Brooklyn, in the county of Kings and State" of New York, have invented new and'useful Im rovenients in Rotary Steam-Engines, of

is a specification.

. This invention a lows accurate adjustment of bearing to be made fromthe outside of the k pt ple construction.

Fig. 5 is a section alo device, so that effective packing can be maintained.

ator therefor, the valve being arranged to be '11 accurate alinement and being of sim- This invention isset forth in the fol owing specification and claims, and illustrated in the annexed drawings, in which v Figure 1 is asideelevation ofa deviceem-' bodymg this invention. Fig. 2 shows parts of Bi 1 in section, 3 is a section along a: z, ig.'j1. Fig. 4 shows a drum and pistons. t i x In the drawings is s own a cylinder a with c'overor head "Asuitable ground joint be- ,plate enables-tight fit or closure te be made. 11 the cylinder 1s, a' rotary drum 0, having e r m he ds "b. As thishe'ad is'adi S b, the drumcan be; th reby s t uste'd for its pistons'd'to close or suitably piece f having an-inclined face. A's the nut g at said piece isloosened andthe screws h turned in the proper direction, the adjuster f is moved to ra1se or set the head. 1

a The cylinder has dowel or dguide pi'ns 'i, and the cover by suitable slotte 'p from the packing. The holes in the cover for elongated-adjustment will be possible. 'T edrum c is shown with pistons d,having I. rods n. These rods are hollow and are practi I ,cally cast or forged with the pistons.


: rods coming from opposite plstons slide or .tlescoprinto one another. Entrances or holes 0 allow pressure to enter to spread the rods or pistons" and hold the latter or the packing p to' the cylinder. The entranceports o have valves or balls g, which at suit tweenfthe cylinder and its head or cover-- I have a' governor 14 of sui ,cOntact at packing a. A certain wear can :thus be compensated for. 'Thisv-hea'd b is shown supported at one, part by anadj-ustingarts straddles .pins'i, so that the cover'is' guided vertically or adjusts along a ,detell'ninndline or. to and able intervals close the holes 0 to prevent escape of pressure, but allow entry of pressure into the sliding stems or-pistons.

The pistons have packings consisting of suitable plates 1", held b pressure through branches 8 from the ho] owpiston-stems to the seats in the drum. At these seats are jplates t of suitable material and having ofi sets or shoulders resting in corresponding ,oflfsets or depressions in the piston-seats in the drum or in the walls of the recesses in which the pistons play. On-dismounting the piston the lining-pieces f can be removedor exchanged.- J i The steam or working pressureis 'allowed to-enter at suitable intervals through valve 2.

This valve is actuated by a cam 3 at suitable intervals. The valve has a stem with antifriction-roller 5-touchin'g the cam. 1

- A sprin .6 is braced against cap 7 of valvecase 8, an this spring tends to hold the valve closed. The stem 9 of the valve has a clamp '10 held thereto by' tightenin screw 11.

This clamp .carries pins 12-, whic are guided in recesses or ways lnthe valve case or cap 7. The guide-pins prevent the valve being turned 01' the antlfric'tion-roller coming into wrong position. In other words," the axis of the roller and that of the'cam are to be parallel.

The steam or pressure-su ly pipe 13 can table construction. The transmission of motion between drum 0 and cam 3 by only two gears would make cam3 rotate in the opposite direction to that of the drum, which in the particular construction shown would not interfere with the operation; but a different number of transmission-gears or different cam-actuation can be provided to change the direction of rotation of the cam or arrange the'movements as desired or called for. l

What'I claim as my invention, and desire to secure by Letters Patent, is-' ,1. An engine-cylinder and head ad'ustably connectedto the cylinder, guides on t ecylinder for the head an adjusting blockvor piece connected to the cyllnder and adjustingscrews for setting the block to adjust the head. l

2. An engine having a cylinder with drum,

and pistons for the drum, said pistons having stems which are hollow to admit pressure from the interior of the drum for holding the pistons in position.

3. All engine-having a cylinder *withdrumand pistons, and hollow piston-stems having vents for allowing the entry of pressure to v spread the pistons;

4. An engine having a cylinder with drum and pistons, hollow piston-stems made-to-'tele scope in one another, and means for su plying pressure into the stems to sprea the pistons.

5. An engine having pistons with stemssuitably chambered for the entry of pressure, said stems having ventsand 'valves-for-closing the vents at suitable periods.

6. A cylinder with drum and pistons; and

a packing between" the drum and pistons, said pistons having a pressure-ventatftl're packing to cause the packing to make tight closure. i

7. A'cylinder with drum, pistons cast with.

hollow stems in the drum, and: means for'admitting pressure into thestemsfor s reading the pistons to contact with the'cylin r;

8. A cylinder comprising a rotary drum with recesses-having ofi'sets; interchangeableto the-piston, and a valve-actuating cam having acting faces corresponding to the pistons.-

10. An engine having a valve with actuating-cam therefor, said valve having a stem with a clampcarrying guideins.

- 11. An engine having a va ve with actuatingrcam therefor, said valve having, a stem with a clamp carrying guideins, and a friction-roller held in line with t e cam by said pins.

12. An engine having a valve-actuating cam, avalve' with -a stem; a housing for 'the valve; pins guided'by' the "housing, and" a: clamp for securing thepins to the-stem:

13; An engine-e linderandh'ead; aguide for the-head,' a settin blook'ha-vin'g one of its faces beveled',-and*" meanewfor adjusting the block.-' I v 14. An engine-cylinderwith a movable head having an inclined portion", asetting block with a correspondingly-inclined face-to engage'the head, and means for adjusting the block.

'In testimony whereof- I havehereunto set my hand in the presence of two subscribing witnesses.
