To ALE WHoM 1r MAY coNcEnN: i A A A Be it known that I, SAMUEL W. HUDSON, oi Beaver Meadow, in the county of Carbon, and State o f Pennsylvania, have invented a' new and useful Steam-Port; and I do hereby declare the following to` be a full, clear,
and exact description of the sameyreference being had to the accompanying drawings, which are'made a para of this specication. V y
The subject of this invention is a steam-cylinder, the ports of which are constructed with vertically oblique passages and with sides parallel to the axis of the cylinder, the object being to introduce the steam and apply the pressure in a gradually-increasing ratio during the first part of the pistons movement, this provision being especially beneficial in cases where 4the piston acts directly without the intervention of a ily-wheel orother means for insuring a uniform motion, Yas indirect-acting steam-pumps, blowers, ttc. o
.Figure I is a vertical longitudinal section of a Vsteam-,cylinder and side elevation ofthe piston.`
Figure 2 is a plan of the cylinder.
Similar letters of reference indicate corresponding parts in the two iignres,
In the drawings, A is the cylinder` and B B the cylinder-heads; C the piston, and Dthe customary stuffing-box through which the piston-rod works. E E are the ports or openings through which the steam is admitted to and discharged from the interiorlcf the cylinder. That -side or wall ofeach steam-port which is 'nearest to the adjacent end of' the cylinder is oblique vertically from its lower terminus tea point in somewhat close proximity tothe upper or outer edge of thol port where the said oblique part e may join'the vertical part el, as seen in iig. 1. 'The part eI and the diametrically opposite wall c2 form the ends of the steam-port, the sides ea e3 beingparallel with the airis oi' the cylinder. Let it be supposed that the piston C is moving toward the cylinder-head B, and that it has reached the position represented in tig. I( By reason of the above-described construction it is apparent that under this position oi' the piston the port Ewill admit less steam Ato the cylinder than it would `underthc ordinary construction. During the iirst part of the pistons movement theobliquc portion e of the side e el effects a diminution in the quantity of steam admitted to the cylinder by as much ns the difference between the distance from the top of face c and. the nearest point on e,'andbetween the face c --and the lower extremity of'e, the latter measurement denoting the capacity of a steam-passage having all its sdesvcrtical, as in the ordinary construction. Hence, as the piston gradually uncovers thesteam-port E, the steam, entering at rst i'n a very limited quantity, is supplied ,in a constantly-increasing ratio until the face e of the piston reacheshthe vertical plane of el, when the continued motion ofthe piston completely opens thc 'port and permits the entrance of as much steam as the eapacitylof the port will admtof. making the sides e of the oblong steam-port E parallel with the axis of the cylinder I provide a further means of supplying the steam more gradually to the cylinder, as the port thus made will be opened to asinaller extent in a given time than a port having its long sides at right angles to the axis of the cylinder.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. The narrow steam-openings E E, arranged lengthwise on the interior surface of 4the cylinder, so as. to be gradually uncovered by the motion of the steam-piston, as herein described.
2. A vertically oblique wall or side e to the steam-port, to adapt the steam-passage to enlarge innn increusfing 'ratio as said passage is opened by the piston for the admission of steam to the cylinder", substantially as described. Y Y
To'theabove specification of my invention I have signed my hand this 20th daynot` Juno, 1867.
