SPECIFICATION forming part of Letters Patent No. 589,603, dated September 7, 1897.
Application tiled December 4,1895. Serial No. 571,056. (No model.)
To LZZ whom zit may concern:
Be it known th at I, ROBERT WILLIAM Kino, manufacturer, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented a certain new and useful Improvement in Clemperature-Regulaters, of which the following is a specification.
My invention relates 4to improvements in ventilating apparatus more particularly adapted for greenhouses Where automatic means are used in connection with the shutters or dampers to operate the same when a slight change in temperature occurs, so they will open and close gradually and positively, and, further, in .applyin g such means when at rest to eftcctually hold the shutters closed during Windy or stormy Weather; and it also consists ot the details of construction, as will be hereinafter described, and particularly pointed out in the claims.
rIhe invention is illustrated in the accompanying drawings, in Which- Figure l is a perspective View, partiallyv in section, of my im proved operating mechanism for the shutters, showing the shutters and operatingmechanism half raised. Fig. 2 is a view showing a vertical section of the valve and the normal position of the lever and valve as it Awould appear when the mechanism is in a half-raised position. Fig. 3 is a similar view showin g the position ot' the double-acting valve and lever during an increase of temperature. Fig. 4 is a similar view showing the position of the double-acting valve and lever when the increase of temperature has stopped. Fig. 5 is'a similar view of the double-acting valve and lever during a decrease of temperature. Fig. 6 is a similar view showing the position of the double-acting valve and lever when the decrease of temperature has stopped.
In the drawings like letters of reference indicate corresponding parts in 'each figure.'
A is a tubular standard which extends from top to bottom ot' the greenhouse, being securely fastened to the iloor and roof.
B is a bracket which is secured to the tubular standard and is provided with an outwardly-extending arm B.
C is a thermostat which is comprised of the arm l with the outside metal plate o and inside metal plates c" and the inner rubber plate c2 and outer rubber plate c3. The plates are made substantially triangular in form.
D and D are hangers suitably riveted to the metal plates c and c'. The hangers D and D have a pin d extending through their lower ends, which are separated and twisted at right angles to the plane of the metal plates c and c', so that the pin d is in a parallel plane to such plates.
'E is a bent lever having a forked end e, which straddles the pin d. The lever E is pivoted at e' on the link F, Which is secured at its lower end to the turning spindle f of the valve Ff.
G is the valve-box, which is provided with the upper port g, side port g', and the lower port g?. A
The valve F is provided with the two ports f and f2, communicating with the central port f3 and the concentric discharge-port f4, which is designed to connect the two ports g and g' or the txvo ports g and g2.
H is a cylinder, theheads H' and H'Eof which are formed Vwith bracket-shaped extensions 7i and h2, by means of which and straps hs and 71,4 the cylinder is secured to and supported upon the tubular standard A.' The cylin lder lil is a double-acting one and is provided with a piston l, having a rod I', which extends through the head H, provided with a suitable bushing. The head has a saucer-shaped recess h at the top, as shown. It is intended that the cylinder should be operated by hydraulic pressure and controlled through the valve F', and for this purpose l provide a supply-pipe J, provided with a faucetj, which pipe leads to the central port f3 of the valve F. The port g in the valve-box G has a downWardly-extending pipe K leading to the saucer-shaped recess h on the top of the head H. The port g2 is connected by a pipe L to the interior of the cylinder through the head H, and the valve-box G is supported by a plate L upon the lpipe L. The valve F is held in position by a set-screw Z, extending through the upturned end of the plate L'. The port g is connected by a pipe M through the head H2 to the interior of the cylinder.
N is a dri p-pipe extending downwardly from the saucer-shaped recess in the head.
O is a reliettap secured in the head H2 and communicating with the interior of the cylinder. The tap O is generally kept closed.
IJ is a lever pivoted upon the hanger p, secured to the bottom of the head II'. The lever P is connected by a rod p' to the bent lever E and by a rod 292 to an arm q, secured to the common operating-shaft Q of the shutters, and is preferably provided with aweight p3 to provide for quick action of such lever. The shaft Q is journaled in suitable hangerbearings R, extending downwardly 'from and suitably secured to the roof S.
T are the sh utters,and Lr the arms,wh ich are suitably secured to the shaft Q. Each arm is preferably provid ed with an end ring u, swiveled to the tubular end bracket u. Through the rin g u extends the connecting-rod t, which is hinged at the top to the bracket secured to the bottom of the sash of the shutters. The rod has preferably formed on it an enlargement t2 and extends through the ring'zo, this enlargement being on the ring u and serving to lift the rod t when said arm U is raised. The enlargement t2 is designed to form a stop against which the lever abuts to lift the shutters without any intervention of a spring. lhe'enlargement t2 also serves to V receive a pressure from the spring a2 of any desired tension to hold the shutter stead y and prevent its vibration or movem ent due to the wind. .p
a2 is a spiral spring extending between the ring u andthe split pin n3, extending through the bottom end of the rod t.
V is an arm secured to the shaft Q and connected by a rod c to the pin e on the sleeve r2, located on the piston-rod I. The pistonrod I at its upper end extends through a supporting-bracket 'W, secured to the tubulaistandard A. The sleeve 'U2 has an outwardlyextending bracing-arm r3 attached to or forming part of the same, which has a forked end extending partially around the tubular standard.
I-Iaving now described the principal parts involved in my invention, I shall briefly describe the operation of the apparatus.
As hereinbefore premised, the piston in the cylinder is shown half raised, so as to half raise the shutter. This is the normal position in which the apparatus is set for the desired temperature of the greenhouse. The normal position of the valve is shown in Fig. 2. Upon an increase of temperature the plates of the therm ostat will expand, and as the rubber plates expand more rapidly than the metal plates it will be seen that the tendency of the elongation of the rubber plates will be to cause the metal plates to curl up at theirlower end, and thereby bring the hangers D and D with the pin d in the direction indicated by arrow. This movement of the pin d will cause the lever to move laterally in the direction indicated by arrow, as shown in Fig. 3, thereby turning the valve and bringing the port f opposite the port g. The water will now pass through the pipe J, ports f3, f', and
g, and by the pipe M through the bottom head ot the cylinder, and thereby raise the piston and swingthe arms U upwardly, so as to further raise the shutter or set of shutters T. Immediately after this action ltakes place the leverq, beiugalso raised at the same time, will draw upon the rod p2 and the rod p", so that the lever E will be tilted on the pin d, acting as a fulerum, and will thus restore the valve F/ to its normal position. Arepeated action like this will continually take place untilthe shutter is raised to its full limit or untiltemperature ceases to rise to normal. ',Should. however, the temperature decrease, the ru bber plates c? and c5, contracting more quickly than the meta-l plates c and c', will cause the hangers D D to move in the opposite direction and bring the pin d in the opposite direction, as indicated in Fig. 5, and thereby throw the'lever E laterally in the same direction, so as to throw the port f2 opposite the port gi. The water now entering through the pipe .I will pass through the ports f3 f2 g2 and pipe L into the top of the cylinder, and thereby force the piston downwardly, so as to close the shutters. Immediately, however, after the port is thrown into the position above described the rod p2 will act upon the lever P and rod p, so as to pull down the lever into the position shown in Fig. 6, thereby throwing the ports of the valve closed again. This action will be repeated until the temperature ceases to fall or theshutters are closed.` i i In Fig. 3 it will be noticed that the port f* connects the ports g and g2, so that when the water is flowing iu at the bottom of the cylinder it may How out from above the piston through the pipes L, ports g2f'1 g', and pipe K into the saucer-shaped top of the head and pass downwardly through the drip-pipe I.
In Fig. 5 it will be noticed that when the water is causing the piston I to move downwardly the ports g and g' will be connected by the port f4, and consequently the water below the piston will be caused to ascend through the pipe M, ports g,f4, and g', and out through the pipe K, as hereinbefore described. c
No matter which way the apparatus may be acting, whether to reduce the temperature by opening the shutters or to increase it by shutting the shutters in order to bring it to normal temperature, such apparatus, being double-acting, will serve as a positive means for forcing the shutters toward the open as well as toward the closed positions.
Should a wind-storm occur and the temperature be suddenly reduced, my apparatus will act very rapidlyto close the shutters and hold them closed.
If in cold weather icicles should form in some of the shutters of the set, it will be seen from the spring V being between the ring of the arm U and the end of the connecting-rod that such spring will give and allow the shutters where the obstacles prevent their closing to only partially close without prc- IIO yenting the eteetnal closing of the remaining shutters of the set. Then the icioles are being caused to `melt from the temperature in the house, it will be seen th'at as the springs are exerting V a constant tension onsuch shutters they will gradually draw them to their seats until they are entirely closed. It will also be understood that a fine adjustment of each shutter of the set in relation to the remaining shutters is not required, as the spring will compensate for any slight difterenee in position, so that when the apparatus is operated all the shutters will be effeetually and completely closed;
Although I describe the spring operating with the actuating-arms of' the shutters in the apparatus hereinbefore mentioned, it will be understood that the same oran equivalent device might be employed it' the apparatus was actuated by hand instead of by hydraulic pressure.
Again, in large buildings it will be understood that the thermostat may be placed in any suitable position in the building and the actuating-valve and operating-cylinder at any7 desired distauee apart Without depart-ing from the essential features of my invention.
What I claim as my invention is`- l. In combination, in a Ventilating apparatus for greenhouses, the shutters, means for automatically aetuatin g the same eomprisin g the thermostat, the pin carried thereby, the cylinder, having a piston, said piston being in connection with said shutters, the Watersupply for said piston, the valve for controlling said supply, the lever fulcrumed on said pin, the connections between said lever and the shutters and the link interposed between said lever and said valve for controlling the same, substantially as described.
