TRIPLE-PIPE BEER-COOLER.

Specification of Letters Patent.

Patented Feb. 16, 1909.

Application filed April 16, 1908. Serial No. 427,431.

To all whom it may concern:

Be it known that I, WiLHnLM GRIEssER, a citizen 'of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented new and useful Im rovements in Triple-Pipe Beer-Coolers, of which the following is a specification.

This invention relates to triple pipe beer coolersy and the object thereof is to provide means whereby the return bends of the pipes can be readily swung from and easily and quickly returned to closing position without separating the same, thus making it unnecessary to completely remove them when it is desired to cleanse or repair the pipes.

I/Vith the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown the preferred embodiment of the invention, but is it to be understood that changes, variations and modifications can be resorted to which come withinV the sco e of the claims hereunto appended.

The drawings illustrate but one end of the cooler for the reason that both ends are identical, the description of one end applying to the other and in the drawings -Figure l isk a side elevation partly in longitudinal section of a triple pipe beer cooler embodying this invention. Fig. 2 is a sectional plan. Fig. 3 is anl end view of the return bend for the inner pipe, and Fig. 4 is an end view of the return bend for the intermediate ipe.

Referring to the drawings by re erence characters, 1 denotes a series of pipe units arranged in parallel relation one above the other and sup orted at their ends in a manner to be hereinafter set forth. Each of the pipe units comprises an inner pi e 3 for ammonia, an intermediate pipe 4 for eer and an outer pipe 5 for brine. These pipes are concentrically arranged in spaced relation and as it will be seen kthe beer will circulate in the space 6 between the pipes 3 and 4 and will t us travel in a thin sheet, as it were, between the ammonia and the brine. The pipes of each unit are connected at opposite ends With the corresponding pipes of adjacent units in a manner to afford a continuous circulationv of the different liquids employed throughout the entire series of pipes. The manner in which a pair of units is connected Will now be described.

l The inner pipe 3 is of greater length than the intermedlate pipe 4, and the intermediate pipe 4 is of greater length than the outer pipe 5.

A head is provided for each end of a pair of pipe units. This head comprises an inner wall 7 and an outer wall 8. These walls have concentric openings 9 and 13, those of the wall 7, however, being of greater diameter than those of the wall S. Secured in each of the openings 9 in the wall 7 is one end of one of the pipes 5 and through each of the open ings 13 in the wall 8 extends one end of one of the pipes 4. Projecting from the wall S and surrounding the openings therein are flanges 11 which are of greater diameter than the pipes 4 and form with the pipes 4 pockets into which project the annular flanges 12 of the intermediate return bend 14.

The outer face of the wall S within the flanges 11 and the ends of the flanges 12 ol' the return bend 14 are beveled, and surrounding thc pipes 4 between said face and ends is arranged a beveled packing 16 to prevent leakage.

The flanges 12 of the intermediate return bend 14 snugly engage the ends of the pipes 4. The intermediate return bend 14 is furthermore provided with a pair of openings 17 through which extend the ends of the pipes 3, the diameter of the said openings 17 being such as to cause the sills el the openings to be in close proximity to the periphery of the pipes 3. The intermediate return bend 14 is furthermore provided with a pair of outwardly extending flanges 1S which surround the openings 17 and projecting ends 19 of the pipes S. The said flanges 18 form pockets into which extend the annular flanges 2() formed upon the outer return bend 2l. The flanges 20 snugly engage the pipes 3. The outer face of the return bend 14 and the end of. the flange 20 are beveled, and to prevent leakage a beveled packing 22 is interposed between the lflanges 2O and the intermediate return bend 14.

The head to which the pipes 5 are secured forms a passage 22a for establishing communication between the pipes 5, the intermediate return bend 14 forms a channel 23 for establishing communication between the pipes G and the outer return bend 21 forms a passage 24 for establishing communication between the pipes 3. The outer return bend 21 and intermediate return bend 14 are so connected to the head for the pipes, 5 that as at 26 the inner end 27 o the said return bend can be swung clear of the said head in a convenient manner, Whereby access can be had to the pipes 3, 4 for cleaning or removing them when occasion so requires. T he manner of connecting the

return bends

14 and 21 to tne head 'will non'v be described.

The nead for the pipes 5 is provided at each side with tivo pairs o apertured lugs 25. Between each pair oL lugs 25 is pivoted ll a relati *ely long bolt. The bolts at one side are indicated by the reference character 28 and at the other side by the reference character 28a. Each of said bolts has two screw-threaded por tions 29, 3() separated by a ilattened portion 31, the screw-threaded porti n 29 b ing of greater diameter than the scre'ahthreaded portion 30. Projecting from one side of the intermediate return bend 14 is a pair oi apertured lugs '32 through which exten the bolts 28a and projecting from one side of the outer return bend 21 is a pair ot apertured lugs 33 through Vwhich extend the bolts 28a. The enlarged portion of the bolt 28a extends through the lugs 32 and the reduced portion of the bolt 28a entends through the lugs 33. Mounted upon the sore 1r-threaded portion 29 of the bolts 28a and bearing against the lugs 32 are the `Washers 34 and mounted upon the sereni-threaded portion 29 of the bolts 28 and engaging the -rfashers 34 are the clamping nuts 35. lilou ted upon the screw-tlneaded portion 30 of the bolts 282l and bearing against the lugs 33 are the Washers 36 and mounted upon ti e serez?- threaded portion 30 of the lugs and engaging the washers are the winged clamping nuts S7. rlhe length o: the bolts 28a is suoli as to project a distance greater than the length of a llange 19 and an intermediate return bend 14. Projecting from the opposite side oi the intermediate bend 14 is a pair ot' biturcated lugs S8 and projecting from the opposite sides of the outer return bend 21 is a pair of biturcated lugs 39. The bolts 28 extend through the said bifurcated lugs, the enlarged portion 'of the bolt 28 extending through the lugs and the reduced portion 30 oi the bolt 2S extending through the lugs Mounted upon the bolts 2S are the 'washers 40, 41 which engage respectively the lugs 39 and the lugs rllhe bolts 2S also carry the clamping nuts 42 and the Ywinged clamping nuts 43. The nuts 42 abut against the irashers 41 and the nut 43 against the washers 40. The bolts 28EL and

nuts

35, 37, 42 and 43 in connection with the lugs 32, 53?., 38, constitute means for retaining the intermediate and outer return bends in position, as clearly shown in Fig. 2 and therv bolts 2Sa in connection with the

nuts

35, 37 and pivots 26 constitute a means whereby the

return bends

14 and 21 can be swung aivay from the head so that access can be had to clean the pipes S, 4 or to remove said pipes ir" it be so desired.

rlhe manner in Which the return bends are disconnected from their normal position so that they can be swung av-.Tay Jfrom the head Will' now be set forth. lt will be assumed that the parts are in the position shown in li ig. 2. as to enable the swinging of the bolts 28 With the nuts thereon away from the bifurcated lugs 3S and 39 so that the release of one side of the return bends 14 and 21 can be had. Aitor such action the nuts 35 are loosened and shifted to a position in close proximity to the lugs 33, the Winged nuts 37 are then loosened and shifted to position in close proximity to the ends of the bolts 28a, the return bend 21 is then shifted outwardly upon the bolts 28@L and the saine action is had with respect to the intermediate return bend 14. Vlhis action positions the intermediate return bend so that the ilanges 19 thereof ifi/ill be clear oi the lugs 25. 'lhe return bends can then be swung away from the head as suiiicient clearance therefor has been provided and when swung clear of the head they Will be carried by the bolts 28a. rlhe pipes 3, 4 can then be cleaned or removed and neur pipes inserted it it be so desired. To place the return bends 14 and 21 bach to their normal position, the bolts 2S are swung baclr upon their pivots 25, the intermediate return bend positioned in the manner as shown in 2, and the same action is had with respect to the outer return bend 21. The bolts 2&3 are swung to their nosition to engage Taridi the biiurcated lugs 38, 39, the nuts are then screwed home and the bends are then iixedly secured in position. She action of removing the return bends is had Without disconnecting entirely the nuts` from their bolts and without separating the return bends from the bolts 28a and it is evident that by ich an arrangement the return bends can be quiclrly and conveniently disoonected from and connected to the head when occasion so requires.
