MORRIS J. GARDNER, OF YORK, PENNSYLVANIA.

OSCILLATING STEAM-ENGINE.

Speccation of Letters Patent No. 9,954, dated August 23, 1853.

To all whom t may concern:

Be it known that I, MORRIS J. GARDNER, ot York, in the county ot' York and State ot Pennsylvania, have invented a-new and useful Improvement on Oscillating Steam- Engines; and I hereby declare that the tollowing is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of my invention consists in the manner of introducing the steam through circular tubes into the steam chest, and at the same time constituting these tubes the circle around which the cylinder oscillates, in the manner substantially set forth, and I do hereby declare that the tollowing is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. y

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Upon the steam cylinder, made in the ordinary way, I construct and tix permanently, a circular steam chest and packing boxes, making the journal the center ot the segment of the circle which the tubes describe, and which the cylinder necessarily makes, as it oscillates over these tubes.

On Plate No. l Figure l sets forth a front external view ot my improvement. a, a, are the circular tubes through which the steam passes into the steam chest and cylinder, being made stationary on t-he frame .ot the engine. o Z) are larger circular tubes attached to the steam chest, inclosing 'the circular steam tubes. These larger tubes, are ot sufficient size to admit of the necessary packing, and also to glide over and around the circular steam tubes. c, 0, is the external plate covering the steam chest, and firmly secured by screws or bolts, passing through the steam chest into the body ot' the cylinder. In the middle of this external plate are two set screws (Z, d, tor the purpose of adjusting a steel plate, back of the valve in the steam chest, to keep the valve tight on the steam ports when the motion is reversed.

Fig. 2, on Plate No. l, represents the steam cylinder, with a side view ot the steam tubes-larger circular tubes and packing boxes.

Plate No. 2, Fig. l, gives an internal View of the whole improvement, showing the manner in which by means ot the circular steam tubes, the steam is introduced into the steam chest and from thence into the cylinder. Also a view of the dissected halt of the larger tubes (constituting at the same time the packing boxes) which pass over the steam tubes as the cylinder oscillates, and also a view of the packing by which it is secured from leakage. a, a, are the steam tubes, that on the right hand the induction and that on the lett the eduction tube. C, is one of the steam ports for the admission of steam into the cylinder-the other corresponding steam port being hid from view by the Valve connected with the eduction tube, as seen at c marked with dotted lines. C, also represents the valve connected with the eduction tube, which as the cylinder oscillates, alternately opens and closes the steam ports, for the admission of steam into the cylinder and at the same time, for the escape of the exhaust steam through the eduction tube.

Fig. 2 is a hollow tubular screw, through which the steam tubes pass, as the cylinder oscillates. This screw is made to screw into the packing boxes attached to the steam chest, at the inner end of the screw, is a projection which is hollow as seen at d.

Fig. 3 gives a side view ot the screw.

Fig. 4 gives a View ot the knob or top ot thejscrew. Into the hollow projection of this screw, is inserted a self-adjusting ring, a little smaller than the hollow projection in the screw, so that it may readily adjust itself, both to the packing and the steam tubes. This ring is beveled on the inside so as to render more compact the packing, and press it against the tubes.

Fig. 5 gives an end view of the screw with the ring in it.

Fig. 6 gives a side view of the ring, the dotted lines represent the bevel of the ring.

The manner in which these screws are inserted into the packing boxes is seen at e, c, and the manner in which the adjusting ring compresses the packing, and presses it against the tubes, is seen at f, f. One of these screws is inserted at each end ot the circular steam chest and packing boxes.

To reverse the motion, all that is necessary will be to have an ordinary steam chest communicating with the circular steam tubes and with a slide valve, to make the educting the inducting, and the inducting provement may also be successfully employed as a Water pump and a blower for furnaces.

That I claim as my improvement is- The mode of introducing the steam-the :circular steam tubes, the circular steam chest and packing boxes operating in the manner herein described. I do not however confine my claim to the precise position or dimensions, of the various parts described in the foregoingspecifications, but to use such positions and dimensions substantially the same, as may be best adapted to produce the 20 desired effect.

M. J. GARDNER.
