SYRUP-DRAWING DEVICE.

SPECIFICATION forming part of Letters Patent No. 579,006, dated March 16, 189'?.

Application tiled May 4, 1896. Serial No. 590,081. (No model.)

To @ZZ whom. t may concern:

Be it known that I, EDWARD S. PALMBLA, a citizen of the United States of America, residing at'Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Syrup-Drawing Devices, of which the following' is a speciication.

My invent-ion relates to certain improvements in syrup-drawing devices, its object being to construct a practical device which shall draw heavy liquids, such as syrup, dre., out of a barrel or cask, and at the same time measure the same into quantities as may be desired.

The invention is illustrated in the drawings presented herewith, in which- Figure 1 is a side view of the device in its preferred form. Fig. 2 is a horizontal section in line 2 2 of Fig. l, but showing the device upon an enlarged scale and the operai:- ing-crank rotated ninety degrees. Fig. 3 is a central vertical section through theline 3 3, Fig. l, a portion of the connecting-pipe being broken away. Fig. 4 is a section in line 4 4. of Fig. 8, showing the piston in its lowest position. Fig. 5 is a similar view, but showing the piston on its downward stroke. Fig. 6 is a section in line 6 6, Fig. 4. Fig. 7 is a section in line 7 7, Fig. 4; and Fig. Sis aperspective view of the piston.

Looking at Fig. 1, which shows the complete device in its preferred form, it will be seen to consist of a crank-operating mechanism and discharge-spout located above the barrel, a pump-cylinder within the barrel and resting upon the bottom thereof, and a pipe connecting the spout and cylinder. The fluid is drawn into the pump-cylinder by the rotation of the operating-crank, forced up through the pipe, and discharged through the spout, the amount withdrawn being indicated The connecting-pipe B is provided with a bushing b, fitted to it and of such a diameter as to iit in the aperture surrounding the pipe B, the bushing being preferably provided with approximately vertical ribs to prevent it from slippingin the aperture when the device is operated. A set-screw b' is provided upon the bushing by which the pipeB maybe hrmly and securely clamped to the bushing, thus securing the entire device in place.

A hollow cylindrically-shaped casting C is screwed to the top of the pipe B, a dischargespout c being provided through which the syrup, 85e., may escape. At the proper place upon the casting is formed a boss c/,in which is journaled a crank-shaft d, having upon its outer end an operating-crank D and upon its inner end a crank d', formed with a spherical vf'rist-pin cl2 near its end, a suitable stuffing-box being formed around the shaft d to prevent any accidental leakage.

' Between the operating-crank D and the stuffing-box I have shown a gear-wheel e, meshing with a second gear-wheel e', journaled upon a shaft secured to the. casting C, the hub of the gear-wheel e being provided with a single tooth c2, adapted to engage wth teeth upon an annular iiange e3 of the indicating-disk E, said disk being pivoted upon ahead C', which is screwed or otherwise securely fastened upon the top of the casting C. This forms a very simple device for indicating the amount withdrawn, the

number of revolutions of the operating-crankhaving previously been determined to measure such quantities as pints, quarts, dac.

Vithin the casting C is a head or slide-block F, formed of two pieces f f', arranged one above the other, a socket f2 being formed in the peripheries at the meeting edges of the two pieces, as seen in Fig. 3, said socket being adapted to receive the wrist-pin d2. The block F is provided with a square hole in which is keyed the piston-rod 29, which extends downward andinto the pump-cylinder, where it is connected with a piston P, the rod being squared at the ends in order that oscillation of the slide-block may be transmitted to the piston.

The pump-cylinder is best seen in Figs. 3 to 7 inclusive, and, as shown, consists in the cylinder proper, A', inlet-port @and outlet-port TOO . a, leading upward and opening into a reducer A2, which is screwed upon the lower end of the connecting-pipe B and connects the same with the cylinder. The upper end of the cylinder A is extended considerably to form a packing-box a2, and a check-valve a3 is arranged so as to slide upon this portion and adapted to seat itself upon the seat formed by the shoulder a4 and face a5 of the pump-cylinder. A head A3 is screwed upon the lower end of the cylinder, said head being formed with a portion A4 approximately parallel therewith and separated therefrom by a number of struts a, thus leaving a series of perforations between the struts through which the syrup, the., may enter between the portion A4 and the head and thence upward through the inlet-port a, said port being, however, also provided with a series of perforations a7, adapted to allow the syrup to enter directly into the port a. As shown, the ports a a are arranged directly opposite one another, the mouth a8 of the outlet-port being slightly above the mouth a9 of the inletport.

The piston is best shown in Fig. 8, and consists of a main portion P' and the overhanging portions P2 P3, arranged on opposite ends thereof .and diametrically opposite, as shown in said figure, the ends of said piston being approximately segments of circles. The main portion P of the piston is of a thickness to close up the mouths of the ports a a', which is done both when the piston is in its lowest and highest position, and during its verticallyreciprocating motion it is oscillated about the piston-rod as a center, in order that the contents of the barrel may be forced outward at both strokes of the. piston. This is accomplished in the operation described below.

In Figs. l, 3, 4, and 6 the operating-crank is in its lowest position, the piston consequently being in the same position and at the same time completely shutting off both ports a a'. If the operating-crank be rotated in the direction indicated by the arrow in Fig. I, it will evidently raise the slide-block F through the engagement of the wristpin therewith, and at the same time rotate said slide-block to the position shown in Fig. 2, which shows the operatingcrank rotated ninety degrees from the starting-point. The piston has now reached the position shown in dotted lines in Fig. 4 and as represented in Fig. 7. This upward movement of the piston evidently draws the syrup in through the port ct and into t-he part of the cylinder proper lettered X, (see Fig. 7,) the port a having been opened through the rotation of the piston caused by the action of the wristpin d2 upon the slide-block. "When the operating-crank reaches a point one hundred and eighty degrees from its starting-point, the piston is evidently at its upper limit, but is again in a position to close off both ports. It will thus be seen that during the entire upward stroke of the piston liquid has been drawn into the part X of the cylinder, the liquid being evidently confined between the inner wall of the cylinder, the face p2 of the piston, the overhanging lip P3, and the lower segment of the piston; but as the piston begins its downward stroke it is rotated in the direction of the arrow Fig. 7, until communication between the portion X of the cylinder and outlet-port a is made, when the liquid will be forced upward through the port a', lifting the check-valve a3 into the connecting-pipe B and out through the spout c. During the downward rotation of the operating-crank the piston F is rotated in the direction above referred to until the operatingcrank passes the point two hundred and seventy degrees from its starting-point, when the piston begins to rotate in the opposite direction and completely shuts off both ports the instant the operating-crank has completed its rotation.

During the downward stroke of the piston it not only forces the liquid confined in the portion X of the cylinder outof the barrel, but also draws liquid into the side Z of the cylinder; that is, between the inner wall of the cylinder, the face p3, the lip P2, and the upper segment of the piston. When the piston again begins its upward stroke, it is oscillated into the position shown in Fig. 7, thus forcing the liquid confinedV in the portion Z upward through the port a and at the same time drawing in liquid on the opposite side of the piston. The check-valve a3 evidently prevents any of these raised liquids from flowing back into the cylinder.

The device thus described is extremely practical and operates equally as well upon such liquids as syrup in cold weather as well as in warm, the same having a great tendency to become heavy and solid in the cold.

I am aware that modifications of this device are numerous, and I do not therefore desire to limit myself, except as particularly pointed out in the following'claims.

I claim as new and desire to secure by Letters Patent- 1.
