SIRUP-GAGE.

SPECIFICATION forming part of Letters Patent No. 333,993, dated January 12,1886.

Application filed October 26, 1885. Serial No. 181,010. (No model.)

To all whom, it may concern:

- Be it known that I, JOHN BROWN, a citizen of the United States, residing at Medi'ord, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Sirup-Pumps for Bottle-Filling Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a perspective view of my improved sirup-pump. Fig. 2 is a horizontal section through the center of the same. Fig. 3 is a vertical section through the center of the same. Fig. 4 is a vertical section on the line as x of Fig. 2; Figs. 5 and 6, details to be referred to.

My invention relates to certain improvements in sirup-pumps which are adapted to be connected with bottle-filling machines, and

which serve to supply the bottle, first, with a predetermined quantity of sirup and then with another kind of liquid-for instance, sodawater; and my invention consists in certain novel combinations of parts and details of construction, as hereinafter set forth,whereby a more effective and desirable apparatus of this character is produced than is now in ordinary use. I

In the said drawings, A represents the pumpcylinder, within which fits the solid piston or plunger B, preferably composed of hard rubber.

b is a packing-1i ng, which is confined in place by a gland, (I, screwed onto the outer end of the cylinder A, whereby any escape of liquid at this point is prevented.

O is a body or casting, provided with a suitable aperture, 0, in which is screwed the inner end of the cylinder A.

Within the body 0, at one side, is formed an independent inlet-passage, f, communicating directly with the inner end of the cylinder at 10, and this passage f has connected with it the inlet-pipe 9, connected with a receptacle containing the sirup or other liquid to be pumped into the bottle.

lVithin the passage f is placed a hard-rubber valve, h, which opens inwardly, and is kept up to its seat bya light spring, i, a series of pins, 7c, arranged around it, serving to guide it in its movements and prevent it from getting out of place. On the opposite side of the body 0 is an independent outlet-passage, Z, communicating with the inner end of the cylinder A at 12, and having the outlet-pipe m, which is connected with the bottle-filling machine. (Not shown.)

WVithin the passage Z is placed a hard-rubber valve, 42, which opens outward and is kept up to its seat by a light spring, 1), and is guided and steadied by pins q, projecting from a non-corrosive metal disk, r, fitting within the aperture 6, at the inner end of which is placed-a washer or packing-ring, s, which serves to prevent any leakage or escape of liquid between the inner end of the cylinder A and the body 0. Ihe body 0 is also provided with a second inlet-passage, t, having a pipe, u, connected with a vessel containing soda-water or other aerated liquid. This passage t communicates with the outlet-passage Z, and is controlled by a valve, a, which is kept up to its seat by a spring, I), and is provided. with a stem, 0, which passes through a stuffing-box, d, on the outside of the body 0, and projects a short distance beyond the outer end of the same into a position to be operated by mechanism to be hereinafter described.

To the outer end of the piston B, on opposite sides of the same, are pivoted, by means of a bolt passing through a journal-box, e, two curved connecting rods or arms, D G, the ends of which, opposite to the pivot, are connected by an adjustable cross-bar, H, which is provided with aperturesf, through which pass the ends of the rods D G, and is secured in place, when adjusted, by means of setscrews To the arms D G is pivoted at h.h' the handlever K, which is composed of two rods or arms, 1" k, which are pivoted to a projection, Z, on the under side of the cylinder, A, by means of a bolt, m, and are connected together at their upper or outer ends by a transverse bar, a, which is adapted to be grasped by the hand and forms the handle for operating the pump. A portion, p,of the rod i extends beyond its fulcrum m and lies close to the face of a stationary plate, q, secured to the projection Z on the under side of the cylinder, as seen in Figs. 5 and 6, this plate hav- ICO ing a series of threaded holes, 1", in one of which is placeda screw-pin, s, which serves as a stop to limit the movement of the handlever K, and thusregulate the outward movement of the piston, and the consequent quantity of sirup which is drawn into the cylinder A to be discharged into the bottle on the inward stroke of the piston. Vhen the pin 8 is removed from the plate q,a permanent pin, t, thereon serves as astop to prevent the piston from being carried beyond the end of its full outward stroke.

The operation is as follows: \Vhen the pis ton is forced outward by the hand-lever K,the valve h is opened and the sirup is drawn into the cylinder at 10 through the passage f, the charge or quantity depending upon the position of the stop-pin which regulates the stroke of the piston. On the inward stroke of the piston, the sirup, as it cannot return through the inlet-passage f,by reason of the closing of the valve h, is forced into the outlet-passage l I at 12, and opens the valve 12 against the pressure of its spring 1), and thence passes by the pipe m to the bottle in the bottle-filling machine.

Just previous to the completion of the inward stroke of the piston the inclined under surface of the bar H is brought into contact with the outer end of the stem 0 of the valve a, which is thus opened against the resistance of its spring I), when the soda water or other aerated liquid will at once pass through the inlett into the outlet passage 1, and thence through the pipe m to the bottle, which is thus filled as required. On again nlovingthe handlever K to force out the piston, the bar H is withdrawn from contact with the valvestem 0, when the valve a will close and cut off the supply of aerated liquid, and the operation continues as before. All of the pipes and the interior of the cylinder are lined with blocktin, while the piston and the valves which come in contact with the sirup are composed of hard rubber, and all liability of corrosion and consequent danger to health is thereby avoided.

By constructing the valve a as shown, and providing it with a stem extending outside the body 0, it is rendered easily accessible for repairs or in case it should become obstructed, and the necessity of taking the apparatus apart, as has heretofore been required,to gain access to the valve, and the consequent loss of time incident thereto, is thus avoided. Furthermore, the apparatus is free from leakage, is very simple, and the construction and arrangement of the hand-lever and its connec tions with the piston 13 are such as to enable the apparatus to be operated more easily and with much less power than heretofore, while the force is exerted in a steady and uniform manner, without unequal strain in any direction.

, Vhat I claim as my invention, and desire to secure by Letters Patent, is-

In a sirup-pump, the combination, with the cylinder A and piston B, of the body or cast ing 0, having the separate inlet and outlet passages f Z, each communicating directly with the inner end of the cylinder and controlled by valves h 02, provided, with springs 2'19, and the separate inlet-passage t, communicating with the outlet-passage Z and controlled by a valve, a, provided with a spring, I), and having a ste1n,'c, projecting upon the outside of the body 0, the hand-lever K,and the rods D G,pivoted to the piston Band t the said handlever K, and provided with a cross-bar, H,

adapted to be brought into contact with the stem 0 to open the valve a at the end of the inward stroke of the piston, all constructed to operate substantially in the manner and for the purpose set forth.

Witness my hand this 22d day of October,

J ()HN BROWN. In presence of- P. E. TESOHEMAOHER, W. J. CAMBRIDGE.
