Patented June 24, 1930 UNITED. STATES PATENT OFFICE ALBERT E. HUTT, OF NEW ROCHELLE, NEW YORK Application filed. October 1, 1929. Serial No. 896,457.

My invention, generally stated, relates to a novel pressure device sed in dispensing fluids and semi-fluids ff om their original containers and is designed to accommodate a can, keg, barrel or the like containing a fluid or semi-fluid, such as oil,'grease, or the like, as usually sold in such manner that when pressure is raised within the chamber of the device it will be exerted alike upon the outside as well as upon the inside of such container, so that while the contents of the container will be forced to the outside of the pressure chamber through a pipe provided for that purpose, the container itself will not have to withstand the destructive force of said pressure as it would have to do if the pressure were introduced on the inside of such container only. My invention further relates to a device having a pressure chamber so arranged and constructed that it may accommodate a plurality of containers.

My invention'further relates to a device having a pressure chamber so arranged and constructed that it may be hermetically sealed and also be provided with means for raising pressure within the same to a point above the pressure of the surrounding atmosphere.

My invention still further relates to the provision of means for indicating pressure raised within the chamber of the device and also relates to the provision of a safety device to prevent such pressure becoming greater than that for which the chamber is constructed.

My invention still further relates to means for drawing-off any water that may accumulate in the chamber of the device due to condensation, for example.

-The invention consists of the novel construction hereinafter described and finally claimed. 4

For the purpose of illustrating my invention I have shown in the accompanying drawings two forms thereof which are at present preferred by me, since the same have been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be vari-' ously arranged and organized and that my invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described.

The nature, characteristic features, and scope of the invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, and in which:

Fig. 1, represents aview in central section of a device embodying my invention.

Fig. 2 represents a.plan View of the top of the pressure chamber showing the lugs which are designed toengage similar lugs on base plate of the chamber. I

Fig. 3 represents an enlarged plan view of the base and l gs shown in Fig. 1.

Fig. 4 represen s a fragmentary view in central section of my novel pressure chamber upon an enlarged scale.

Fig. 5 represents in vertical section a detail of the check valve construction herein-- after referred to.

Fig. 6 represents a view in vertical section of a modified form of construction.

Fig. 7 represents a sectional plan view of Fig. 6. g

Fig. 8 represents in vertical section a detail hereinafter referred to.

Referring now to the drawings in detail, and especially to Figs. 1, 2, 3,-and 4, the reference numeral 1 designates the pressure chamber of my novel device and comprises a generally cylindrical member having an integral dome-shaped up er part2 and, a separate base 3. The reference numeral 4 designates the retaining lugs upon the dome shaped upper part 2, and 5 designates similar lugs on the separate base 3. 6 designates a turn table in the base. 3 to facilitate moving of the barrel when the lugs 4 are engaged with the lugs 5. 7 desi nates a circular seal of flexible material, pre erably rubber, which seals the joint between the casing 1 and the base 3. The higher the pressure raised in the chamber -1 the tighter the'seal'is maintained between'the sealing parts. 8 designates a metal drum or container having a regular opening 9 through which passes .the casing 1, for the purpose of turning the same to engage the lugs 4 with the lugs 5. 13 designates a pressure relief valve. 14 designates a pressure indicating gauge and 15 indicates a check valve through which compressed air is introduced into the casing 1 prising the pressure chamber is shown as uried beneath flooring 16 of a building. 17 designates a cover to close the opening 18 beneath it, which opening is for the purpose of lowering the drums 8 into the interior of casin 1. 19 is a pipe leading to the pressure relie valve to be placed at any suitable place above the floor. 20 is a pipe leading to the pressure gauge also placed above the floor, and 21 is a pipe leading to the check valve for the introduction of compressed air. 22 is a valve for the purpose of drawing off any water into a sewer by way of pipe 23. The seal 28 in this installation seals the joint between the casing 1, opening 18 and the cover plate 17. 24 represents stuffing boxes to seal the joints in the telescopic pipes 10 and to hold them in a raised position while the drums are placedbeneath them or are removed when empty. 25 designates any .suitable means for heating which in the present case may be steam coils for the purpose of heating the interior of the chamber if desired. While in Fig. 6 I have illustrated the heating means as being applied to the device as shown, it will be understood that suitable heating means may be applied to the device as best seen in Fig. 1. v

The operation of both of the devices shown in the above described figures being identical in principle, it is only necessary to refer to Fig. 1.

Referring now to Fi 1, the drum 8 is placed. upon the turnta le 6 of thebase 3 and the closing plug is removed from the aperture 9 of the drum. The dome-shaped member 2 is then placed over the drum 8 and on the base 3 so that the lugs 5 cooperate with the lugs 4 and the telesco ic p1pe 10 fits through the aperture 9. e domeshaped member 2 is then turned by the handles 12 so that the lugs 4 pass under the lugs 5. The drum 8 will have to turn with the dome-shaped member as the pipe 10 passes loosely through the aperture 9 of said drum, whereb the pressure is exerted directly upon tlie contents of said drum or container. The seal 7 is fixed, in any suit- Referring now to Fig. 6, the casing 1 comthe desired pressure is reached within the casing 1, as ,will be indicated by the gauge 14. The pressure of air acting upon the seal 7 will close the casing 1 hermetically. As the pipe 10 has a loose fit with the aperture 9 the pressure the casing 1 will be evenly distributed both inside and outside of the drum 8 and directly on the contents of the latter so that there is no tendency for the drum to break open. The pressure of air, however, acting upon the contents of the drum 8 will force the contents thereof out through the pipes 10 and 11.

vided with steam pipes 25 passing around the inside of casing 1 forthe purpose of raising the temperature of the contents of the drums 8 to facilitate passage of such contents through the pipes 10 and 11 if they were of a character as to need this assistance, which would be the case with heavy bodied greases and the like.

It will be apparent that with the use of my novel pressure device I am enabled to greatly facilitate the removal of fluids and semi-fluids from comparatively fragile containers with the aid of air pressure, which is quite desirable and, commercially considered, possesses advantageous features.

By the above arrangement, construction and combination of parts I also have provided a relatively inexpensive, simple and eflicient pressure device for the removal of fluids and semi-fluids from relatively fragile containers. Another advantage resides in the fact that my novel construction of parts may be employed above ground or beneath ground, as desired.

Referring now to Fig. 5, the same illustrates in central section the air inlet 15 shown at the top of Fi 1. In this figure the. top 2 of casing 1 is s own with an opening 26 to admit air, and the attachment is provided 'with a spring pressed spherical valve 27 Referring now to Fig. 8, I have shown in detail the stufiin boxes 24 illustrated in Fig. 6. A stufling ox is provided in each pipe 10 to prevent air leakage from the casing 1, when the contents of drum 8 is below this point. The lower or smaller pipe section which telescopes into the upper or larger pipe section 10 is provided with the parts 29, as seen in Figs. 1 and-8, to permit the ingress of the fluid or liquid which is to be dischar ed through'the outlet pipe 11, which may ,e provided with a check or other The construction shown in Fig. 6 is provalve 30 if desired' The eye 31 on the dome will cause them normally to assume substantially the position seen .in Figs. 1 and 8.

It will be apparent from the foregoing that by my invention I am enabled to utilize a standard or conventional lubricant drum or container having a fixed top and by merely removing the plug or closure from the aperture 9 and loosely inserting therein the exit pipe 10, and its adjuncts, a free space is afforded for exerting pressure directly upon the contents of' the "container through the opening 9, and I am thus enabled to dispense with a follower and a stuffing box thereon as has heretofore been proposed. By my device the lubricant canbe readily dispensed from the original container without the use of spoons, paddles, or the like, and the lubricant or other material is at all times protected from the ingress of' dirt, dust, or other foreign and deleterious substances. It will be obvious that my invention is equally well adapted for dispensing any other material than lubricants in a fluid, plastic, or semi-plastic condition.

I am aware that the invention may be em-' bodied in'other specific forms without departing from the spirit or essential attributes thereof, and I therefore desire the present embodiment to be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.
