PATENT CHARLES SINNIG, OF- STQLOUIS, MISSOURI, ASSIGNOR TO TI-IE SINNING LASTING MACHINE COMPANY, OF SAME PLACE.
SPECIFICATION forming part of Letters PatentvNO. 546,354, dated September 17, 1895. :Application filed November 4, 1893. Serial No. 489,997. (No model.)
To @E whom t may con/cern? i Be it known that l, CHARLES SINNING, of the city of St. Louis, in the Statecf Missouri, have invented a certain new and useful Pressure Device, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specication.
My present invention relates to certain iinprovements in the construction ofthe pressure device shown and described in my Patent No. 458,920, issued September l, 1891, the object of my present invention being to simplify the construction, prevent leakage, and to make *ne device more sensitive and quick in its acion.
My invention consists in features of novelty hereinafter fully described, and pointed out in the claim.
Figure I is a iop View of the device. Fig. lI is a horizontal section of the same, taken on line II Il, Fig. IV. Fig. III is a vertical section of the device, taken on line III III, Fig. I. Fig. IV is an elevation of the device. Fig. V isa horizontal section taken on line V V, Fig. IV. Figs. VI and VII are horizontal sections of the valve, taken on line VI VII, Fig. III. Fig. VIII is a section of the valve taken on line VIII VIII, Fig. II.
My invention is designed more particularly for regulating and controlling pressure and is Well adapted for use in connection with a lasting-machine for regulating the pull of the nippers that grasp and pull the leather over the ast.
l represen ts the cylinder of the device, having a port 2 forming a communication between its bottom and a chamber 3 located at the upper end of the cylinder. The port 2 communicates with the chamber 3 through means of a horizontal passage 4..
5 represents a valve located between the upper end of the cylinder and the chamber 3, the chamber having an opening 6 opposite the valve, and the cylinder having an opening 7 opposite the valve.
8 represents the piston of the cylinder l, and the stem 9 of the piston is connected to the object to be moved bythe piston.
10 represents a bushing fitting in the upper head of the cylinder and extending a distance into the cylinder, as shown, s0 as to prevent any possibility of the piston rising so far as to cut oft the opening 7. The upper head of the cylinder and thetop of the chamber 3 is formed by the bottom, l1 of a chamber I2, located over the cylinderand over the chamber 3. The piston-rod 9 passes through this chamber 12, as shown in Fig. Ill, and on top of the chamber 12 is a tube 13, through which the piston-rod also passes. The internal diameter of the tube I3 is somewhat larger than the diameter of the piston-rod, so that any liquid carried up by the piston-rod will travel down it again and be caught by the tube and carried back into the chamber l2, or, in other Words, by making the tube 13 larger than the piston-rod its upper end does not scrape or remove the liquid from the piston-rod, but such liquid as is carried up on the rod gravitates back into the chamber l2, l
14 represents a pair ot' wheels located in the chamber 3, and which force or conduct the oil to the valve 5, the Wheels turning in the direction of the arrows, Fig. II, and the spaces between the teeth being filled with oil, While such spaces at the adjacent sides of the Wheels are occupied by the teeth of the wheels, and the oil is thus displaced at the valve side of the wheels, as will be plainly seen. One end of the journal or arbor of one of the Wheels is extended through the top 15 of the chamber l2, and has upon it a bevel-Wheel 16 engaged by a similar wheel 17 on a shaft IS, by which the wheels le are turned. The stem 19 the chamber l2 (see Fig. III) and has upon it a crank 20, (see Fig. IV,) which is connected to a treadle (not shown) by means of which the valve is operated. The form of the valve 5 is illustrated in Figs. II, VI, VII, and VIII. It has a straight passage 2l, which forms a communication between the chamber 3 and the upper end of the cylinder l. 0n one side municating through an opening 23 with the chamber 3 when the valve is turned in the proper position for this communication. The lower end of the passage 22 communicates with the passage or port 4., as shown in Fig.
of the valve 5 extends through the top l5 of f of the passage 21 is a vertical passage 22, com- 9 5 VIII. On the other side of the passage 2l is a passage 24, whichalso communicateswiththe port 4 at bottom, and which has Van opening 25 adapted t0 register with the opening 7' in the upper end of the cylinder 1, and an opening 26 adapted to register with the opening 6 from the chamber 3. When the valve is in the position shown in Fig. III, the liquidk passes from the chamber 3 into the upper end of the cylinder l above the piston 8. When the valve is in the position shown in Fig. VI,
the liquid passes from the chamber 3 into'thev 4, thus allowing the piston 8 to be drawn up by the pressure on the rod 9. When the valve is in the position shown in Fig. VII, the liquid is permitted to pass from the chamber 3 into the port 4 and back to the chamber, while the liquid is not allowed to escape from the upper end of the cylinder, the piston 8 at this time being held against the tension or force of the rod 9 by the body of liquid above it.
When the valve is inthe position shown in Fig. lll the piston 8 is of course under the influence of the action of the wheels 14; but when the valve is in either of the positions shown in Figs. VI or VII, the action of the wheels I4 does not atleet or act upon the pist0n 8, and thus 'the pump is allowed to run continuously, whatever the desired condition of the piston 8 may be. The dilerent posi tions of the valve 5 are effected by the operator through the treadle connected to the crank 20, and he can effect at will a downward movement of the piston 8, (by moving the valve to the position shown in Fig. IIL) or permit an upward movementof the piston 8, (by'moving the valve to the position shown in Fig. VL) or he can cause the piston 8 to remain at rest (by moving the valve to the position shown in Fig. VIII). y v
By locating the chamber 3 at the upper end of the cylinder 1, with butthe small space occupied by the valve 5 between them, the different actions of the piston 8 occur almost simultaneously with the movement of the valve 5. The chamber 12 providing a reservoirfor surplus liquid, and the tube 13 communicating with the chamber l2 avoids any escape of liquid from the pump. In practice the chamber 12 is kept about half filled with liquid, while the parts beneath are of course all full of liquid.
The operation ofl such a device, as above de.- scribed, in a lasting-machine is fully described in my pending application filed June 27, 1893, Serial No. 478,991; but it is evident my invention may be applied to other uses.
I claim' as my invention- In a pressure device the combination of a cylinder l, a piston working in said cylinder, a chamber 3 located at the upper end of' said cylinder and having communication with the top and bottom thereof, a pair of wheels located and working in said chamber, a valve located between said chamber and the upper end of the cylinder, and means for moving said valve and wheels, said valve having a passage 2l for forming the communication between the cylinder and chamber 3, a passage 22 provided with an opening 23 and a passage 24 provided with openings 25 and 26 for forming communications between the chamber 3 and passage 4 and chamber 3 and cylinder l, substantially as and for Vthe purpose set forth.
CHARLES SINNING.
