BLOWING-ENGINE OR COMPRESSOR.
Specification of Letters Patent.
Patented July 21, 1908.
Application filed August 4, 1906. Serial No. 329,177.
T 0 all whom it may concern:
Be it known that I, GUSTAV B. Pn'rsorin, a subject of the Emperor of Germany, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented a certain new and useful Improvement in Blowing-Engines or Compressors, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.
My invention relates to blowing engines or compressors and has for its object to provide an engine of this kind having circumferentially arranged admission ports extending through the walls of the cylinder at each end thereof and the sliding gridiron delivery valves working on the heads of the cylinder; my invention also comprising other detailed features of construction, all of which will be best understood as described in connection with the drawings in which they are illustrated and in which Figure 1 is a side elevation of an engine embodying my invention. Fig. 2 a plan view thereof. Fig. 3 an end view with the manhole lates, indicated at G, G, removed, and the elivery valves broken away from their actuating rods. Fig. 4 is a longitudinal section on the line 44. of Fig. 3, and Fig. 5, a section through one of the auxiliary cylinders taken as on the line 55 of Fig. 3.
A indicates the end of the actuating engine which maybe of any usual or convenient construction; B, B, extensions of the engine framing which connect it with the compressing cylinder.
O, is a crosshead guide. I), D, portions of the base supporting the fixed cylinder heads indicated at E, E, said heads, as shown, being made up of the cylinder heads proper, indicated at E the cylindrical portions E which serve as bearings for a reci rocating cylinder body to be described, the head portions E being formed with grid iron ports indicated at E E located on o posite sides of the center of the engine and aving valve seats indicated at E formed on the outer side of the head E. From the heads E extend the hollow hubs E the outer ends of which connect with the casing E between which and the heads E are formed the receiving chambers F F. i
E, E, indicate openings in the casing E normally closed by the plates G, G.
F indicates a common receiving chamber connecting the chambers F, F.
H, is the movable cylinder body supported and moving on the cylindrical portions E E of the heads and having at each end a series of circumferentially arranged admission ports H. The cylinder body, as shown, is also provided with a central circumferential groove indicated at H I is a bearing shaft supported above the cylinder and sup orting at its ends, the U-shaped yoke I iaving a bearing pin I at its lower end to which is connected the actuating rodJ. The arms of the yoke support the bearing pins I 1 which project into the groove H and support friction rolls 1*, 1*, which fit in said groove H The rod J connects with the lever arm J on the rock shaft J 2 which is actuated through lever arm J and rod J 8 by some constantly moving part of the engine not shown. There is also attached to the rock shaft the lever arm J which communicates motionthrough rod J the double armed rock lever J and the rock lever J to the rod N.
K, is the piston rod, K the piston working in the cylinder, K a crosshead supported on the bearing C. L, L, etc., are sliding delivery valves moving on the bearings E to 0 en and close the ports E, E". The upper va ve L of each cylinder head has its stem or valve rod R connected with thepiston Q working in the auxiliary cylinder P and having. attached or connected to it the dash pot piston Q working in the extension P of cylinder P, as shown. Laterally extending bearing pins Q connected with each piston Q, as shown in Fig. 5, are pivotally connected to the upper forkedend of a rock lever S which is fulcrumed on the engine casing midway between the stem R and the stem R of the corresponding lower delivery valve L. The stem R is pivotally connected to the lower end of the rock lever S. Inconsequence of this arrangement the two delivery valves on each cylinder head move in opposite directions to open or to close.
P indicates a passage through the auxiliary cylinder casting and supporting the cam O, two of such cams being attached to each rod N in connection with the auxiliary cylinders arranged at each end of the compressing cylinders.
T, T, are conduits connecting with the auxiliary cylinders P and connecting, as shown, through flexible pipes T with the interior of the cylinder H T, T, are valve boxes of the usual kind employed in such connections.
In operation the piston is moved back and forth in the compressing cylinder and at the same time the oscillations given to the yoke I cause the cylinder body H to reciprocate in such manner as to alternately open the circumferential admission ports H, H, at its ends. A relatively uniform motion is given to the sliding cams O, O, which are arranged so as to act upon the cam rollers Q and move the pistons Q into the bottom of the auxiliary cylinders P and thus move the delivery valves in a direction to close the delivery ports E E immediately in advance of the beginning of the motion of the piston K away from said ports. Immediately after closing the ports the high portions 0 of cams 0 move out from under the cam rollers Q leaving the pistons Q free to open and they do open when the-pressure entering the auxiliary cylinders through the conduit connections T become su'lliciently high to overcome the frictional pressure holding the delivery valves to their seats.
It will be seen that the structure claimed herein provides in a simple and effective manner ample .port space for both admission and delivery and retains all features of rapid and well timed movement of the valves which characterize the best features of modstationary cylinder heads having receivers inclosing their outer ends and delivery ports formed through them in combination with a longitudinally reciprocating cylinder body fitting on said heads, circumferential admission ports situated at both ends of the cylinder and opened and closed by the movements of the cylinder body, sliding gridiron delivery valves moving on the outer faces of the heads, means for closing the delivery valves moving in fixed relation to the movements of the cylinder body and independent means for opening said valves.
2. In a blowing engine. or compressor,.
stationary cylinder'heads having receivers inclosing their outer ends and two sets of delivery ports formed through them, one set on each side of the center of the head, in combination with a longitudinally reciprocating cylinder body fitting on said heads, circumferential admission ports situated at both ends of the cylinder and opened and closed by the movements of the cylinder body, two sliding gridiron delivery valves moving on the outer faces of each of the heads and so placed and connected that they move in opposite directions to open and close their delivery ports, means forclosing the delivery valves moving in fixed relation to the movements of the cylinder body, and independent means for opening said valves. 7
3. In a blowing engine or compressor, the
combination of stationary cylinder heads, a longitudinally reciprocating cylinder body having a circumferential groove formed around it, a yoke pivoted at one side of the cylinder, means for oscillating said yoke and slides secured to the side of the yoke and fitting in the groove of the cylinder whereby the cylinder is reciprocated.
