LOUIS I-I. BRINKMAN, OF GLEN RIDGE, NEW JERSEY, ASSIGNOR TO GENERAL INDUSTRIES COMPANY, A CORPORATION OF NEW YORK.

FLUID-MOTOR OR THE LIKE.

Application filed January 12, 1912, Serial No. 670,924. Renewed September 23, 1913.

To 64% whom it may concern Be it known that I, LOUIS H. BRINKMAN, a citizen of the United States, residing at Glen Ridge, in the county of Essex and State of New Jersey, have invented a new and useful F luid-Motor or the like, of which the following is a specification.

Hy invention relates to a fluid operated motor mechanism, and especially to one hav ing a variable point of reverse, that is suitable :Eor use in bottle capping machines, hammers, and other engines of variable stroke.

One object of my invention is to provide an arrangement of the class described with a main piston having a controlling port therethrough and a valve controlling said port whereby the valve may be carried by the piston in order to easily and efficiently obtain a variable point of reverse controlled by the movement of the piston.

A further object of my invention is to provide means whereby the point of reverse may be adjustably varied.

A further object of my invention is to provide an arrangement of the class described in which the main piston is controlled by a valve and the valve controlled by a pilot valve and which is extremely simple and efiicient and especially suitable for the purposes for which it is designed.

A further object of my invention is to provide an arrangement of the class described, which is not liable to stick or get out of order and which is capable of operating at high speed in a most eflicient manner.

lVith the above and other objects in view, my invention consists of the novel construction, combination and arrangement of parts as hereinafter specifically described and illustrated in the accompanying drawings wherein is shown the preferred embodiment of the invention, but it is to be understood that changes, variations and 1nodifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings, Figure 1 is an enlarged sectional view in elevation of the working cylinders and internal pistons and valves of my invention, as applied to a bottle capping machine used in putting on what is termed a metallic cap and seal; such a machine being shown in elevation in Fig. 2, Fig. 3, is a sectional view taken on line AB of Fig. 1 looking in the direction of Specification of Letters Patent.

Patented Apr. 28, 1914.

Serial No. 791,403.

the arrow E; Fig. 4, is a sectional view taken on line CD of Fig. 1 looking in the direction of the arrow F; and Fig. 5 is a view in section showing a continuation of that shown in Fig. 1.

1 is the main cylinder, 2 is the lower cylinder head secured to main cylinder 1, and containing packing 3. 4 is the upper main cylinder head, 5 is a piston cylinder which operates through lower cylinder head 2, and packing 3, and has secured on its outside end lower piston cylinder head 6, to which is attached crimping die 54, and through which operates piston rod 7, at the lower end of which is carried the cap hold down 8.

To piston rod 7 is secured piston 9 which operates in piston cylinder 5. Piston 9 carries automatic adjustable valve operating rod 10 which may be adjusted by thread 11, and nut 12. This adjustment in a bottle capping machine is regulated according to the height of the cap used, or the relative difierence in movement desired between the piston cylinder 5, and the piston rod 7. Piston 9 is packed in piston cylinder 5 by packing 13, and to the upper end of piston cylinder 5 is secured the main piston 14, cup washer 15 being secured to main piston 14 and packing the same in main cylinder 1 by being held by piston cylinder 5.

16 is the valve casing secured in main piston 14. In valve casing 16 at one end is secured an annular ring 17 in which is secured exhaust tube 18. A short distance from ring 17 in valve casing 16 are secured annular spacing members 19, between which annular spacing members 19 are passages 20. 21 are passages in valve casing 16, 22 and 23 being annular rings secured in the valve casing just above and below the passage 21.

24 is a valve cylinder secured to spacing members 19, and rings 22 and 23.

25 is the main piston valve operating in the valve cylinder 24.

26 and 27 are valve cylinder heads secured one in each end of valve cylinder 24. In valve cylinder, heads 26 and 27 are valve ports 28 and 29 connecting with clearance spaces 30 and 31. In valve cylinder 24 are ports 32 and 33 adapted to be opened and closed by the piston valve 25.

34 is a rotating valve, divided centrally as shown in Figs. 3 and 4 one half thereof 35 connecting with the exhaust and closed at its lower end 36, the other half 37 being connected with the pressure in the main cylinder, and having its upper end closed to the exhaust at38, 39 40, 39 and 40' being circular ports in said valve. Rotary valve 34 at one end has an operating cam 41 which is rotated or operated by a pin 42 on adjustable valve operating rod 10. At the other end of rotating valve 34 is secured operating cam sleeve 43 having cams 44 and 45 at either end thereof, which cams are operated by pin 46 secured on reverse limit rod 47, which rod is secured in exhaust head 48 by set screw 50. Exhaust head 48 is secured in the outer end of exhaust chamber 49, which chamber is secured to upper main cylinder head 4. Reverse limit rod or valve operator 47 is adjustable by means of screw 50, and controls the limit of the reverse movements of the main piston 14, if said piston is not reversed before the limit is reached on downward stroke by the adjustable valve operating rod 10.

51 are openings in piston cylinder 5 allowing free communication between the lower end of the main cylinder 1, and piston cylinder 5.

52 is the main inlet; and 53 is the exhaust port.

54 is a crimping die secured to lower piston head 6.

56 is a collar secured to valve 34 and keeps it in place, and 55 is a feather preventing the rotation of piston 9.

The operation in the described embodiment of my invention is as follows: The fluid enters inlet 52 into main cylinder 1, through opening 51 into piston cylinder The pressure in main cylinder 1 on the inlet end of main piston 14 and in piston cylinder 5 are always equal and substantially the same as inlet pressure. The fluid is conducted from piston cylinder 5 through the half 37 of rotating valve 34 which is open to piston cylinder 5 and through port 39 in to valve port 28, valve clearance space 30 thus forcing or keeping main piston valve 25 in the position shown in the drawing, the space below the valve 25 being exhausted through ports 29 through the half 35 and exhaust tube 18. lVith the valve 25 in this position fluid is admitted through valve passage 33 from piston cylinder 5 through passage 21 into the upper end of main cylinder 1, thus forcing main piston 14 down together with piston 9 the exhaust valve passage 32 being closed by piston valve 25.

A bottle being placed in the capping machine as shown in the drawings, Fig. 2 and Fig. 5, cap hold down 8 and crimping die 54 come down on the bottle; cap hold down 8 forcing the cap on and securely holding the same on the bottle, piston cylinder with attached crimping die 54 continuing to descend crimping the cap on to the bottle and until piston 9 with its attached adjustable valve operating rod 10 and pin 42 operates cam 41, rotating valve 34. This limits the down stroke since on the rotation of rotating valve 34, inlet circular port 39 closes on port 23, and the port 39 opposite in the exhaust half of said rotating valve opens to port 28 thus permitting exhaust from the upper end of the piston. valve 25, at the same time the lower end of the piston valve is connected with the cylinder 5 through port 40 and port 29, thus admitting the pressure of piston cylinder 5 under main piston valve 25 forcing the same up, closing valve passage 33 and connecting passage 21 and passage 32 together thus permitting an exhaust from the upper end of main cylinder 1 through passage 21, piston valve 25, passage 32 in valve casing 16, openings 20 between the spacing members 19 and out through exhaust tube 18 into the exhaust chamber 49 and out of exhaust 53.

If there is no bottle in the machine or other obstruction to force piston 9 in on descent of piston. cylinder 5, then pin 46 operates cam 44 thus rotating valve 34 as before; at the limit of the upstroke pin 46 operates cam 45 thus rotating valve 34 and thus reversing the motor. It will thus be seen that I have provided a most simple and eflicient arrangement embracing a main piston 14 having a port 33, 21 therethrough the opening and closing of which controls the movement of the piston, a fluid operated valve 25 controlling the opening and closing of said port, a rotating valve 34 passing through the first named valve and controlling the movement thereof and means such as 42, 10, 46, 41, 45, 44, whereby the movement of the piston controls the movement of the rotating valve. Such an arrangement is capable of quick action, not likely to get deadlocked or stuck at slow speeds and not likely to get out of order.

By varying the sizes of the ports in one or both of the valves described the speed of the piston stroke with a given fluid or pressure may be varied.

If the ports are comparatively large or the fluid light and elastic the piston can be made to deliver a rapid hammer blow, and it is obvious that this hammer blow produced by the described movement of the piston may be utilized for any purpose in the arts for which such a hammer blow may be desired, such as riveting or rock drilling.
