cLosURE OPERATOR yFilled Oct; l5.` 1935 3 Sheets-Sheet 2 Feb. 22, '1938. J. l.. CARRILLO A cLosuRE OPERATOR Filedoct. 15, 1955 s sheets-,sheet s Attorney Patented Feb. 22, 1938 UNITED STATES PATE CLU SURE OPERATQR l Claim.

This invention relates to operating devices, for doors, windows, or analogous devices and among the objects of the invention is to provide a simple and efficient means for shifting the closure to either open or closing position.

In accordance with the present invention, the closure operator consists broadly in the provision of a cylinder having a piston mounted for reciprocation therein and connected with the closure for opening and closing the same, together with novel valve means for controlling the supply and exhaust of air to the cylinder for reciprocating the piston.

The invention, together with the objects and advantages, will be best understood from the following description taken in connection with the accompanying drawings, wherein- Figure l is an elevational view illustrating the application of the invention to a door.

Figure 2 is an end elevational view of the cylinder.

Figure 3 is a sectional View thru the cylinder showing the manner of connecting the piston with the door.

Figure 4 is a detailed sectional view on the line 4-4 of Figure 3.

Figure 5 is an end elevational view of the piston.

Figure 6 is a longitudinal, sectional view through the cylinder and piston illustrating certain details hereinafter more fully referred to.

Figure 7 is a detailed, sectional view through the cylinder showing the means for sealing the slot provided in the cylinder as and for the purpose hereinafter more fully disclosed.

Figure 8 is a detailed, sectional view through a valve control for the operator,

Figure 9 is a fragmentary side elevation view of the valve control.

In the illustrated embodiment thereof the invention is shown as applied to a sliding door. Thus referring to the drawings in detail, it will be seen that 5 indicates generally a sliding door. In accordance with the present invention there is suitably mounted in the adjacent wall and the upper casing of the door opening an elongated cylinder l. Fitted on the end of the cylinder are caps 8 provided with apertured flanges 9 through the medium of which, and through other fastening devices I, the caps are secured with the cylinder 9 in position.

Mounted for reciprocation within the cylinder I is a piston, consisting as shown, of a body Il having pins I2 projecting from relatively opposite ends thereof as shown. Through the medium of the pins I2 and nuts I3 there are secured on relatively opposite ends of the body of the piston, packing rings i5 and cup washers I5.

Suitably mounted within the respective opposite ends of the cylinder 'I and carried by the caps 8 are rubber covered bumpers IS which limit the movement of the piston l I.

The piston body l I has formed integrally therewith a stepped lug il having a sliding t in stepped grooves i8 provided in the bottom of the cylinder at opposite sides of the longitudinally extending slot i9.

Integral with the lug il is a shank 23 terminating in a depending substantially U-shaped shoe or attaching member 2l. The shoe or attaching member 2i straddles an upper forward corner of the door 5 as best shown in Figures 3 and 4, and through the medium of rivets or other fastening devices 22 said shoe is positively secured to the door 5 for transmitting movement of the piston to the door.

Connected to and within the respective opposite ends of the cylinder l as at 23, is an elongated spring metal tape ifi that is of a width to substantially close the slot I9 as shown in Figure 7. The tape Ztl is trained through a suitable opening 25 provided therefor in the aforementioned lug I'I as clearly shown in Figures 4 and 5. The peripheries of both the packing members lli and the cup washers i 5, at their lower diametrical points, bear upon the tape Eli and hold the latter in sealing position upon both sides or the shank 2i) and piston body Ii. It will be seen that pressure on the tape 2d will tend to seal the slot I9 behind the piston H against which air pressure is exerted for moving the piston in one direction.

Extending upwardly through one side of the door casing, and leading from any suitable source of air supply is a pipe 26 which has an end 26a connected with an inlet 2i on one of the caps 8. Branching from the pipe 26 is a pipe 26h that is connected with an inlet 28 provided on the other of the caps 8. The caps 8 are provided with exhausts 29 and 39 respectively.

Provided in the pipe end 26a, and pipe branch Zib, are manually operable valves 3|.

Each of the valves 3i, as clearly shown in Figure 8, consists of a suitable cylindrical casing 32 in which is mounted for reciprocation a suitable valve 33, (Figure 8), normally urged in one direction through the medium of a spring 34. On one end the valve 33, (Figure 8), is provided with a suitable push button or stern 35. It is thought that the operation of the device Will be clear from the foregoing. However the operation may bebriey'set forth as follows:

With the door in the closed position as shown in Figure 1, opening of the door is effected as follows. The operator presses in on the button 35 of the valve 3|V associated with the pipe end 26 so that air from the source of supply will flow from the pipe 26 through the pipe end 26a into the cylinder 1 at the left-hand end of the cylinder and thereby act on the piston ll to move the latter towards the right. Obviously, as the pist0n moves in this direction, door 5 will move therewith in a corresponding direction'to open position. Y

With the door in an open position, it may be moved to a closed position by the operator pressing the push-button 35 of the valve 3| Varranged in the pipe branch 26. The air under pressure will then ow from the pipe 26 through the branch 2Gb into the cylinder I at the right hand of the cylinder and thereby act on the piston Il to move the same toward the left. Obviously as the piston Il moves in the direction for moving the door to a closed position, air at the left hand side of the piston willexhaust from the cylinder 1 through the exhaust 29, thus permitting the piston to move freely lin the direction indicated for closing the door'5. In this connection it will be noted that in the opening of the door 5 air in the cylinder I VWill exhaust through the exhaust 30.

Having thus described the invention, what is claimed is:

In a device of the class described, a cylinder provided with an elongated slot therein, the sides of said slot being stepped inwardly, a pisto-n mounted for reciprocation in said cylinder, said piston having a shank extending therefrom and operating in said slot, the sides of the shank being stepped to register with the stepped sides of the slot, means for connecting the respective ends of the cylinder with a source of air supply for reciprocating said piston, and means'for sealing the slot in the cylinder Without impairing the reciprocatory movement of the cylinder, said means including a ilexible tape anchored at its respective opposite ends to said cylinder, said tape extending longitudinally in said slot and said shank having an opening therethrough accommodating said tape.
