ELEVATOR FOR LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 509,437, dated November 28, 1893.

Application led February A2, 1893. Serial No. 460.674. (No model.)

To a/ZZ whom. t may concern:

Be it known that I, SYLVESTER JENKINS, o Lansdale, county of Montgomery, and State of Pennsylvania, have invented an Improvement in Liquid-Elevators, of `which the following is a specification.

Myinvention relates to elevators for liquids, and consists of certain improvements which are fully set forth in the following specification and are shown in the accompanying drawings which form a part thereof.

My invention is particularly designed for lifting ales and other liquors from a cellar or portion of a building Where they may be kept in quantity, as in the'barrels or kegs, to the bar room or place of delivery. Some liquors, such as ales, are injured if they are forced through pipes by pressure as it is necessary that they shouldvbe quietly drawn from the barrel or keg when desired for use. My invention is designedto permit these liquors to be drawn from the barrel or keg into glasses lowered in the elevator, without rendering it necessary for the attendant to leave the bar or place of delivery.

It is also an object of my invention to enable the attendant to so control the delivery of the liquor, that one, two, or more glasses may be filled at a time, as maybe desired, so that no more liquor may be drawn from the keg or barrel than is actually required'.

It is also an object of my invention to prevent the overliowing of the glasses While being illed, and also to avoid any spilling of the liquor due to the jolting of the elevator carriage while it is being raised and lowered.

I shall now refer to the accompanying drawings for the purpose of describing my improvements.

In the drawings: Figure l is avertical sectional view of my improved elevator for liquids. Fig. 2 is a similar View on the line x-a: of Fig. l. Fig. 3 is a plan View of the top of the same. Fig. 4. is a horizontal sectional View on the line y-y of Fig. 2. Fig. 5 is a perspective view ofy the elevator carriage. Fig. 6 is a vertical sectional View on the line .e-z of Fig. 4. Fig. 7 is a longitudinal sectional View of the valve device on an enlarged scale. Fig. 8 is a horizontal sectional View on the line o o of Fig. 2 on an enlarged scale. Fig. 9 is a horizontal sectional view on the line w-w of Fig. 7. Fig. 10 isa similar view on the line u-u of Fig. 7. Fig. 11 is a similar view on the line t-t of Fig. 7; and Fig. l2 is a vertical sectional view on the line o-v of Fig. 2.

A is the elevator shaft, which will usually extend from the cellar, or lower floor at which the liquor is discharged, to an upper iioor or point of delivery. The upper portion of the shaft may be located in a bar or counter to present a neat and attractive appearance; the upper end of the shaft A may be closed by a cover or cap A provided with apertures a for the glasses, thus concealing the elevator carriage, and its mechanism from view.

B is the carriage which consists of a suitable frame B adapted to move freely up and down in the shaft A. Carried by the top of the carriage frame B are a series of glass seats or cups C which receive the glasses C. I have shown the frame B provided with four of these seats or cups C, and I consider that number preferable, but more or less may be employed as maybe desired. The seats or cups may be received in sockets or holes c2in the frame B.

The carriage B is guided in its vertical movement by a suitable guide. This I have shown composed of vertical rods B2 Within the shaft A extending through eyes b in the frame B. Suitable lifting mechanism is connected with the carriage B for the purpose of raising and lowering it.

The particular form of lifting mechanism which I have shown is as follows:

D is a small shaft journaled in the upper portion of one of the Walls of the shaft A, provided on its outer end with a crank d by which it may be rotated.

D and D2 are two disks fast upon the inner ends ofk the shaft D, one of the disks, as D2 being of smaller diameter than the other. The larger disk D is connected by a cord or cable c with the carriage B, so that the car` riage B will be raised or lowered in the shaft A, when the cord c is Wound up or unwound upon the disk D when the latter is rotated by its shaft D. The smaller disk D2 is connected by a cord or cable c with a lever D3 hinged to a sliding weight E and having a notch d. The weight E is guidedin suitable guides e in the shaft A. The diskD2 may be IOO provided with a hub d2. The disks D and D2 may be grooved upon their peripheries as shown to permit the cords c and c respectively to be wound up upon them. The cords c and e are so disposed with reference to one another that the one will be wound up upon its disk while the otheris being unwound, and vice versa. Thus when the cord cis unwound to lower the carriage B in the shaft, the cord c is wound upon the disk D2 and the weight E is elevated. The end of the lever D3 to which the cord c' is connected is provided with a finger d2 which projects over and rests upon the periphery of the disk D2 when the cord c is wound thereon.

The object of employing the smaller disk D2 with its connections, is to prevent the jolting of the carrier B and quietly arrest it when it is raised or lowered in the shaft, so as to prevent it from stopping with a sudden jolt which might upset the glasses. In Figs. l and 2 I have shown these devices as they will be when the carriage B is lowered. Then the handle d is turned to raise the carriage B, the cord c is wound upon its disk D and the cord c is unwound from the disk D2 allowing the weight E to descend. As the disk D2 rotates to unwind the cord c the lever D3 at first swings outwardly away from the hub d2 and then descends under the action of the weight E. During this movement the linger d2 of the lever D3 travels over the periphery of the disk D2. When the carriage B is fully elevated it is on a substantial level with the top of the shaft A immediately under the cap or cover A', so that the glass supports C, or the glasses carried by them, extend up through the apertures Ct. Then the carriage B is lowered by turning the handle d to unwind the cord c, the cord c is wound upon the disk D2 elevating the weight E and lever D3. Nhen the cord c is wound upon its disk D2 the end of the lever D2 reaches the disk, and as the disk continues to rotate, the finger cl2 travels over a portion of the periphery of the disk until it reaches the position shown in Fig. l, when the notch d lits over the hub d2. W ith this construction the movement of the carriage B when it reaches the top or the bottom of the shaft is gradually arrested without a jolt or jar. Ordinarily1 during the rotation of the disks D and D2 the carriage B is raised or lowered for any extent of rotation a distance equal to the length of cord cor c wound or unwound. Vhen, however, the carriage is almost lowered in the shaft, the end d2 of the lever D3 comes in contact with the periphery of the disk D2, and as the disks continue to rotate, it travels over the periphery of the disk D2 until it reaches the position shown in Fig. 1. At the same time the cord c has been wholly unwound from the disk D', and at the time the end of the lever D3 reaches the disk D2 the point of connection of said cord c with the disk D' is approximately ninety degrees from the vertical line. As the disks continue to rotate this point of connection travels down with the disk into the vertical line passing through the axis ofthe disks as shown in Fig. l so that the distance which the carriage B is lowered by this downward movement is only equal to the vertical distance which the point of connection of the cord c has moved from its position at ninety degrees to its position on said vertical line, instead of the distance equal to the length of the cord that would he unwound from approximately a quadrant of the periphery of the disk. The movementof the carriage B is consequently diminished at this point for the same amount oi movement of the disks D D2, and as the movement is a gradually retarded one, the carriage l5 is quietly arrested in its descent, and without a sudden jar. A similar action takes place when the carriage B is raised. .I ust before the carriage reaches its highest elevation, the cord c becomes entirely unwound from the disk D2 and its point of connection with the disk D2 is approximately forty-live degrees from the vertical line passing through the axis of the disk. Upon the further rotation of the disk D2 this point of connection travels down with the disk until it reaches said vertical line and similarly brings the carriage to a gradual stop. The finger d2 in traveling over the periphery of the disk D2 also acts to some extent as a brake. The weight E acts to counterbalanee the carriage B. iVhen the end of the lever D3 reaches the position shown in Fig. l further movementis arrested. The end d2 of the lever D3 at this moment should be slightly to the right ofthe line extending from the hinge point of lever with the weight through the axis of the disks D', D2, so that the weight shall not act to turn the disk D2 back and thus again raise the carriage B. The carriage B is thus automatically stopped and held in its lowered position.

F, F, are liquor pipes extending through the lower portion of the shaft A into a tubular sleeve G located centrally within the shaft A. The pipes F, F, may be connected externally with the barrels or liquor reservoirs through suitable pipes or hose.

I have shown two 'feed pipes F, F, either' of which may be connected with a barrel or reservoir by the valve mechanism hereinafter described. It is to be understood, however, that a single feed pipe may be used.

II is a tubular liquid supply pipe or valve section extending through the sleeve G and free to turn therein. This tubular supply pipe or valve section is provided with valve ports or openings 1', r adapted when the part I-I is turned to open either of the pipes F, F through the sleeve G. The section Il is also provided with outlets 7L above the pipes F, F fitted with projecting nozzles h.

F is a rod arranged vertically within the shaft A, journaled at its upper end, as atf, in a suitable bearing and connected at its lower end with the upper portion of the valve IOO IIO

section l-l. The rod F may be provided with a handle F2 at its upper portion projecting through a slot g in the shaft A. By moving the handle F2 the rod F may be turned and with it the valve section H so as to open either of the openings r, fr to the pipes F, F. Whenv a single pipe F is employed, one opening r will suffice.

I is a tubular valve piece closed at one end and open at the other, located within the valve section I-I with its closed end at the top, and movable longitudinally within the section H.

The valve piece I is provided with a series of valve holes i, t and A single hole t' is located at a distance from the open end of` the piece I, two holes '11', i', are located in a row at a point below ythe hole t', and three holes i2, t2, t2 are located in a row at a point below the holes t', 'i'. The holes t and fi', and t2, t2, t2 are located a distance apart corresponding with'the distance between the outlets h of the section H. "With this construction any number of outlets hin the tube H may be opened through the valve piece I.

Normally the Valve piece is in its lowest position within the tube H, and the highest hole is below the level of the outlets h. It is apparent that with the valve piece I in this position the outlets h will all be closed. If now the valve piece I be moved up sufficiently to bring the single hole 'i in line with the outlets h and the tube I-I be turned until one of the outlets h is opposite the hole t', a single outlet h will be opened, and the liquor may liow through the holes fi and h and the nozzle h. If the rod be lifted higher, so as to bring the row of two holes @7,17 in line with the outlets h, two of the valves will be opened. By lifting the piece I still higher until the holes 2 are in line with the outlets h, three of the valves may be opened, and if the piece I be raised so that its end .passes above the outlets h, all will be opened.

It will be observed that I have shown the holes t', t" and i2 in the valve piece I arranged to suit the number of outlets h from the tube H. It the number of these outlets h be increased or diminished the number of valve openings or holes in the piecelwill of course be correspondingly altered. The valve piece I is thus provided with valve openings arranged in successive series of increasing number at different elevations.

The valve piece I is provided with suitable connections for moving it vertically in the section H. The particular devices for this purpose shown in the drawings are as follows:

I is a rod located within the shaft A and connected by a pin j with the valve piece I through a slotfin the section I-I. The rod I may be connected with the pin j by a hinge connection j and the outer end of the pin may be guided vertically in a suitable guide j?.

J is a lever pivoted as atv lo on the outside of the shaft A and connected with the upper end of the rod I, so that when the lever J is moved on its fulcrum the rod I will be raised or lowered.

It is apparent that the amount of movement of the lever J upon its fulcrum 7c will regulate the extent of vertical movement of the Valve piece I and consequently the number of the nozzles h that are opened. A segmental catch bar S may be arranged upon the outside of the shaft provided with catches to indicate the extent of movement of the lever J to open one, two, three or more of the outlets h. The lever J may be guided in its movements in a suitable guide S.

The seats or cups C are arranged upon the upper portion of the frame B of the carriage B. One or more of these seats or cups may be carried by a yielding supporting piece. Ordinarily it is sufficient for one of the seats or cups C to be so carried.

L is the yielding support for one of the cu ps. In the drawings I have shown this support as a spring fastened at one end asat Z to the top of the frameB and adapted to carry the cup or seat C at its other end.

M is a set screw carried by alug ofthe frame B for adjusting the spring support L, and thus regulating the amount of its movement.

m is a stop or projection carried by the spring support L.

N is a bell or gong carried by the frame B.

O is a hammer adapted to strike the gong N. The hammer O is pivoted as at o to the frame B and is adapted normally to fall by gravity and strike the gong N.

O2 is a set screw carried by the hammer O and adapted to strike the frame B when the hammer falls, so as to cause the hammer to strike the gong with a spring blow and return out of contact with it.

O is a weighted dog pivoted to the hammer O or adjacent to it, and normally bearing upon the hammer below its pivot point so as to hold it out of action in an elevated position as shown in Figs. 5 and 6.

P is a projection located within the shaft A near the bottom and adapted to strike the dog O when the carriage Breaches its lowest position so as to elevate the dog and lift it out of contact with the hammer O.

P is a linger carried by the hammer O and so located that it will normally strike the stop m when the hammer is released and prevent it striking the gong \T.

When the support L is in its normal position, fi. e. when it is sustaining the weight of the cup C and the empty glass supported thereby, the stop m will obstruct the finger P and prevent the hammer O striking the gong. When, however, the weight sustained by the support L is increased by the addition of the liquid to the glass which it carries, the support L is depressed so as to free the finger I and permit the hammer O to fall. This device is intended to sound an alarm so as to indicate when the glass has been filled. It is desirable that the hammer should not be permitted to strike the gong until the proper IIO fr teaser quantity of liquor has been received by the glass. To insure this action, and to prevent the accidental release of the hammer O before the glass is filled, which might be caused by a slight jar to the carriage when it is lowered tending to depress the yielding supports for an instant, I prefer to employ a second or auxiliarystop m', locatedimmediatelyin front of the stop m and holding the hammer O, so that, if for any accidental reason the yielding support L is depressed for an instant and releases the hammer O, the hammer will be arrested by the stop m and will be held thereby until the support L is positively depressed by the increased weight due to the flow of the liquor in the glass supported by it. By this means the action of the alarm at the proper time is insured. My invention, however, so far as this yielding support and the alarm mechanism controlled thereby, are concerned, is not limited to the use of an auxiliary stop m'. It will be observed that as soon as the carriage B is raised so that the weighted dog O is lifted from the stop I), the dog O will swing back to its normal position and lift the hammer O.

Q is a stop carried by the frame B and extending over the support L to act as a stop to prevent the spring support rising unduly high when it is relieved of the weight of the glass.

R is a pin carried by the lower extension of the tubular valve piece II and adapted, when the valve piece H is turned in the manner heretofore described to open the opening 9*, to project over a portion of the frame B so that the carriage may not be elevated in the shaft A until the valve piece H is turned back and the opening r is closed. As the outlet nozzles h are turned with the tube H so as to project over the glasses when the carriage B is lowered, it is apparent that if through the carelessness of the operator the carriage B were raised before the tube H were turned back the glasses would be caught by the projecting nozzles 7L and would be upset. The pin R elfectually prevents this, however, and compels the attendant to turn the tube H back and close the valve before the carriage can be elevated. The pin R thus constitutes a lock controlled by the valve mechanism to lock the carriage against movement until the valves are closed. IVhile it is highly preferable, it is not, however, essential to the invention.

I shall now describe the operation of this apparatus. In its normal condition when the carriage B is elevated the tube H is turned in such a position that the openings r are closed and no liquor may flow through the pipes F into the tube H. The valve piece I is in such a position that its valve apertures are all out of line with the outlets h. When the tube His in this position the projecting nozzles h are so located that they will present no obstruction to the descending carriage B. The frame B of the carriage extends about the tube II and rod F so that when the carriage is lowered in the shaft the glasses C are grouped about the tube H as is indicated in dotted lines in Fig. 11. This particular shape of the frame B so as to group the glasses about the tube His, of course, not essential tothe invention. The carriage B when elevated is immediately below the top or cap A and the glasses C are placed in the seats or cups C. The carriage is then lowered by the rotation of the handle d in the manner heretofore particularly described,and when it reaches the bottom it will be in the position shown in Figs. l and 2 with the tops of the glasses C just below the nozzles h. The stop or projection P elevates the dog O so as to release the hammer O, which is, however, held out of action by the stop m, as has been explained. The lever J is now moved to operate the valve piece I according to the number of glasses which it is desired to fill. If one glass is to be filled it will be moved so as to bring the single opening 't' in line with the apertures h, or if more glasses are to be filled, it will be moved proportionately as has been explained. The extent of the movement of the lever J in each case may be indicated upon the catch bar S. The handie F2 is now shifted to turn the rod F and tube H so as to open the port r and permit the liquor to flow through the pipe F into the tube H. IVhen two pipes F, F are employed, the lever may be shifted either to the right or to the left to open the one pipe F or the other as may be desired. The turning ofthe tube H to open the port r at the same time turns the nozzles 71. over the glasses C and brings the outlets 7L in coincidence with the valve openings fi, tbc., so that the liquor may flow from the nozzles h into the glasses. IVhen the alarm mechanism is employed with a single glass the outlets t', t', t2, dsc., should be so located that the single opened valve, or when a series of the outlets are opened one of the series, shall be opened to the glass that is supported by the yielding frame L which con trols the alarm mechanism, so that whether one or more glasses are illed the alarm will be operated and indicating for one glass, will indicate for all. For this purpose the outlet and one of the outlets of each of the succeeding series as t" and t2 should be in the same vertical line and in a position to supply the glass carried by the yielding support.

While I prefer the details of construction that have been shown I do not limit my invention to them as it is apparent that they may be varied without departing from the invention.
