GUY B. COLLIER, OF KINDERI-IOOK, YORK.

GAS-LIGHTING APPARATUS.

Lacasse.

To all whom t may concern:

Be it known that I, GUY B. COLLIER, a citizen of'the United States, residing at Kinderhook, in the county of Columbia and State ofNew York, have invented certain new and useful Improvements in Gas-Light ing Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

rIhe present invention relates to gas lighting apparatus and more particularly to apparatus of this type which automatically lights and extinguishes the main gas burner at predetermined intervals.

It is the object of the present invention to reorganize and improve apparatus of this character whereby the apparatus is rendered more efficient and certain in its operation.

l/Vith this object in view the various features of the invention consist in certain novel features of construction, combinations and arrangements of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art from the following description.

In the preferred form of the invention Figure 1 represents a front elevation of the improved apparatus; Fig. 2 is a side elevation partly in section of the apparatus attached to an ordinary type of lamp; and Fig. 8 is a detail illustrating upon an enlarged scale certain important features of construction.

The construction shown in the illustrated embodiment of the invention comprises essentially a clock mechanism and a timing mechanism operated thereby for opening and closing a gas valve at predetermined intervals. The cloclrmeohanism and timing mechanism are conveniently combined to form a single unitary construction which operates a suitable type of gas valve to cause the lighting and extinguishing of the gas at predetermined intervals and without manual intervention. The apparatus is conveniently inclosed in a casing 10 supported by a main gas pipe, indicated at 11. A. tubular arm 12 extends horizontally from a casing secured to the gas pipe and is provided with a threaded end13 which is received within a boss 14 formed'upon the upper end of the casing 10, as shown clearly in Fig. 2. The

Specification of Letters Patent.` Patenggd App, 16,1918, Application filed December 27, 1916. Serial No. 139,106.v

gas pipe is inclosed within a hollow post 16 in the usual manner and supports the base 17 of the lamp. The specific form of gas valve is not illustrated herein but may be the same as that shown and described in the patent to Collier No. 1,133,265, March 30, 1915. This valve isoperated byarock shaft 1S extending through the hollow arm 12 and provided upon its opposite end with an operating arm 19.

In order to prevent the escape of gas from the main gas passage through the hollow arm into the casing 10 the rockv shaft 18 is provided with a series of washers 20 of felt or other similar material which surround the rock shaft within the arm 12. Lubrication is supplied to the rock shaft through an oil duct 22 formed in the arm 12 and communicating with the washers. `The provi-V sion of a plurality of washers received within the arm and fitting the rock -shaft serves two functions. The washers act as a container and oil reservoir for maintaining the shaft lubricated and at the same timeform an effectual seal for preventing the escape ofgas from the gas passage into thecasing 10.

If the gas should by any chance leak through The timing mechanism is constructed and arranged to open and close the gas valve kby moving the rock shaft in opposite directions. To this end an opening member and a closing member are employed and are. ar.-

ranged to operate the gasv valve through the rock shaft at predetermined intervals. In

. the illustrated embodiment of the invention Ythese members consist of a pair of dogs carried by two rotating dials which are geared to ,ether-v to rotate in opposite directions and` are conveniently driven from the large gear 85 of the clock mechanism. It may be men-V tioned that this is a usual gear incident to'.

clock mechanisms of this type so that a c0111-,

of the drawings it will be noted that a pair of dials 36 and 37 journaled upon a pl back plate 25 through a plurality of standards 4:0. The dials 36 and 37 are provided, respectively, with `gears ell vand l2 having the same nuinberoi1 teeth and meshing with oneanother to cause the dials to rotate in opposite directions at the same speed. The gear 42' is drivenfrom the cloelr gea-r 35- through a small gear mounted upon a shaftlaiid meshing with the gearv 35 and a pinion Zl5 secured to the shaft 44- and mesi ing .with the gear 42.. The intermediategears are ari'angedto rotate the large gears 41, and a2 oncein each twenty-tour hours.

in orderto permit an adjus of the dials relative to the clock mechanism, means are conveniently provided for permitting a relativerotation' of the gear e3 and shaft del. lc this endthe gear il isk trictionally locked to. tliefshaft la by a spring which maintains .onefface oit the gear in yielding engagenient-ivith a shoulder informed integralwithtlie shaft. The opposite end ot the spring engages .with a collar 48 secured by appin i9 extending through the shaft le-l. With this cons" `uction ther shaft isfnorinally rotated with thepinion i3 but maybe adjusted relative thereto by engaging the squared end 50 of the shaft with a suitably shapedkey.

The valve operating shaft is operatively connected with the opening and closing dials are provided and are at e3@ secured to theV` slot and-arranged to traverse between oppov siteends of the slot, as indicated in Fig. 3V or' the drawings, andthe arm 19 is provided .with a studl received within a branch 62 .of the slot extending lengthwise of the leverV lthrouglrtwo levers which may be referred torrespectively, as an actuatingv lever and a valve lever. The actuating lever is operated atpredetermined intervals by the opening and closing .dogs carried by the dials and in turn serves to move the valve lever from one operative position to another in which the valve isV either opened or closed. After the valve lever has been movedto one of two operative positions to open or close the valve it serves to retain thegas valve in this position until again moved bythe actuating lever. vAccording to this construction a valve lever 60 is ulcruined .upon a shaftl extending from -the back plate 25 and an actuating lever is fulcrumed upon shaft 5ft secured to 'the back plate, as shown clearly in ll'igs. 2 and 3 ofthe drawings. rlhe valve lever is arranged to be rocked into one of Iwo inclined positions by the actuating lever and is retained yin either inclined position by a weight 55- secured rto the. end ot the valve lever5 as shownclearly in Fig. 2 of the drawings.-

Thevalve lever is provided with an enlarged .portion Y. adjacent the-"lower end having a 60. YV ith this construction the movement of the actuating lever from the positioi'i shown in Fig. 3`to a position in which the actuating lever is inclined in the opposite direction causes an abrupt movement-iol the valve lever 60 in corresponding direction and rocks the arni'19 sufficiently to open the valve. rlhe movements ofthe valveflever are lim? ited ywhen the lever is disconnected from the arm 19 and the operative position of the lever is determined when the inain'frfas valve is opened by stud (lprojecting rron the back plate 25" and receivedwithin'a depression 66 formed Vin the slot- 565 vas shown clearly in F 3. ln order 'to insure that the gas valve. maybe completely closetL 'the stud G5 is not normally arranged tor'engage with the depression (5G when the valve lever is located in the inclined position oppositev to that shown in f r VThe actuating'lever 53 is intermittently moved in opposite directions byan opening member 68 rotating with the dialBTandfa closing` member 69 rotating with the dial 86. Y

lbe observed that the Vrotation of' the dial 37 in the direction of the arrow causes'the'stud 71 to engage beneath'the wing ot the actuating lever, tipping the lever gradually` about the fulcruin 5l. ln a like' manner the rotation of the dial 36 in the opposite direction causes the closing 'member to gage beneath ,the wing 73 of the actuating lever, tipping' it in the opposite direction.

The actuating lever is retained in :an iiiclined position and tliemovements from one inclined position to another are aided by release and accelerating lever 75 ul'crumed at 76 upon the' back plate and having its free end engaging with a stud?? projecting from the actuating lever. lt will benoted from an inspection of Fig. 3 that the end of the arm in engagement with the stud is provided with oppositely inclined. taces'78 and which are maintained in engagement with the stud by a coiled Sdsurrounding the fulcrum 76 and serving to normallyde? press the lever 7 5. l/Vith this construction the lever serves to retain the actuatingv lever in either inclinedp'o'sition to'whicliit is moved and to' aid in nio'v'ing rthe leverto this position afterit has passed the vertical.;

lio

1,262,753 A Y f In order to insure the operation of the valve lever by the actuating lever the latter is provided with a weight 872 on the outer end.

According to the above construction one of the wings 72 or 73 of the actuating lever is first engaged by a rotating stud which slowly rocks the lever from an inclined to a substantially vertical position. At this point the stud 77 passes from one inclined face to another of the controlling arm 75 which causes the controlling arm to impart an abrupt movement to the actuating lever, aided by the weight 82. This continues until the stud 57 has engaged with vthe end of the slot 56 and moved the valve lever from one inclined position to another.

It will be observed that both the dials 36 and 37 are marked to indicate hours and that each dial is provided with a pointer 85 moving therewith and a stationary pointer 86 mounted above the dial. The stationary pointer, when read in connection with the dial, shows the actual time, las indicated by the dial, and the movable pointer is connected to the corresponding opening or closing member and indicates the position ofthis member and the time at which the gas valve will be opened or closed. For example, upon observing Fig. l of the drawings it will be noted that bot-h ofthe dials indicate in connection with the stationary pointers that the time is three-thirty a. m. The pointer 85 in connection with the dial 36 indicates that the gas valve was closed at one-thirty a. m. and the pointer 85, in connection with the dial 37, indicates that the valve will be opened at theJ following seven-thirty p. m.

In order to set the movable pointers relative to the dials to vary the opening or closing of the main gas valve each pointer 85 is connected to a corresponding arm 70 through an arbor 90 having a squared end to receive a key, as shown clearly in Fig. l. The dial is loosely received upon the arbor and is provided with a hub journaled in the front plate 25. The dial is normally secured to the arbor through a cup shaped spring washer 92 which serves to clamp the arm 70 and the hub of the dial together. This construction normally causes the arm 70, pointer 85 and dial to rotate together but permits the pointer and arm to be adjusted relative to the dial when desired,

lVhile it is preferred to employ the specific construction and arrangement of parts shown and described, it will be understood that this construction and arrangement is not essential except so far as specified in the claims, and may be changed or modified without departing from the broader features of the invention.

The invention having been described,

, what is claimed is:

the fulcrum, a stud projecting from the acl tuating lever into the slot, a valve shaft, an arm secured to the valve shaft and a stud projecting from the arm and received in a recess formed in the valve lever intersecting the slot to cause the movements of the valve lever to operate the valve shaft.

2. A gas lighting apparatus, comprising a pair of oppositely rotating dials, a clock mechanism for rotating the dials at a predetermined rate, an arm associated with each dial and rotating therewith, an actuating lever fulcrumed at one end and having a pair of oppositely extending wings, a stud projecting from. each arm and constructed and arranged to engage with one of the wings to cause the rotation of the arms to rock the actuating lever at predetermined intervals, a valve shaft, and connections between the valve shaft and actuating lever.

3. A gas lighting apparatus, having in combination, a tubular support, a valve shaft journaled in the support, a plurality of yielding washers surrounding the shaft within the support and an oil passage eX- tending through the support into communip ing face of the shoulder to frictionally clamp the gear to the shaft, a rotating dial, connections between the shaft and dial, a valve shaft, and operative connections between the dial and valve shaft for rocking the valve shaft at predetermined intervals.
