would otherwise be necessary if the eccentric.
To arf/J 'whom t may concern:
Be it known `that l, RICHARD WHITAKER, a citizen of the United States, residing at NewBrunswick, county of Middlesex, State of New Jersey, have invented certain new and useful Improvements in Gas-Pumps, of the following is a specification.
pumps for compressin gas, such as ammoniaro gas in ice-making mac unes, and isa division of my application filed January 11, 1904, Serial No'. 188,612.
i The objects oi the present invention are to produce a pump made oi as few parts as pos- :5 sible and connected to ether by ground joints, so thatpacking wil be dispensed with. lother object is to provide means for se y arating ammoniagas which may leak b t e packing-rings oiv the piston into the oil-c amzo er.
l attain these objects by theinechanismA illustrated in the accompanying drawings, in which lligure 1 is a sectional view of a pump simi 2 5 lar to that disclosed in my original application and embodying my present invention, and llig. 2 is a modification thereof. vln both of the views like parts are designated by thesame reference characters.
The casing 1 is of the general shape shown and is provided with a bearing 2, a gland 3, 4 and packing-rings d tori the passage oi the actuating-shaft 5. A cover 6, naving a bearing?, is secured to one side` ol" the casing 1 by 3 5 means of stub-bolts d, the joint between them and the casing being ground or otherwise ren dered yoil-tight, so that the easing will serve as a receptacle for Vthe lubricating-oil The eccentric 9 is provided with integral bearing Jortions or stub-shafts l0, which are mounts within the bearings 2 and 7, any end play being prevented by engagement with the cover', which also holds the eccentric in position. The shaft 5 i asses throughthe a5 center of the eccentric an is secured iu place by any suitable means, such as the key 11. Ey `mounting the eccentric upon integral bearing portions no support is given to it by' the shaft 5o part rotary' motion to the eccentric.
shaft therefor may be of smaller size 5, the latter serving merely to im The than 's invention relates to improvements inwere directly supported upon-it. It may be removed and a shorter or longer shaft substituted without changing the ad'ustment oi the bearings for the eccentric ano it need not be so accurately alined, as would be the case if the eccentric were supported upon the shaft directly. Another advantage lies in the fact that the eccentric and supporting bearing portions being cast in one piece is much cheaper than il' it were keyed directly to the shaft.. Furthermore, the key 11 may be made longer and applied or removed with greater facility.
The outside cover 12, dished, as shown, is applied to the cover 6 and forms, in conjunction with the cover 6, adouble cover, constituting a condensing-chamber 13. The cover 12 is preferably secured in place by the saine set of securing-bolts as are used i'or the inner cover. This chamber communicates with the inside of the casing 1 by two 4or more small o enings 14, one above and thc other below t e level of the oil, and by means of which the oil within the chamber 13 will always be at the same hei ht as that within the casing 1. The cham er 13 serves the purpose of a condensing-chamber and ermits the escapeof the ammonia-gas w ich may leak by the packin -rings of the piston into the oil-casingl. T e escaping gas may be drawn ofi by means of the pi e 15 into the gas-tank and again compressed) and loss oi ammonia thereby prevented. y
The cylinder 16 is entirely separate from the casing and is provided with a ground shoulder 1?', Whichrests upon the upper part oi the casing 1 to form a gas-tight'joint. The cylinder is preferably provided with an integrally-formed water-jacket 18 and a ground p er face 19. Upon the upper face 19 is a va ve support or guide having a ground upper face which'rests upon a valve cap or crown similar to that disclosed in my original application and in m application led January 5, 1905, Serial o. 239,724. Means is shown in these two a plications for patent for clamping the va ve-guide and valve against the upper part of the c linder, so that the valve may e removed wit great facility.
The piston is secured to the connectingrod 21 by means of any suitable bearing, but prefer-ably by that Which forms the subjectmatter of an application for patent filed by me on the th day of January, 1905, Serial ably cast integralwith the communicates with the jacket 18' of the cylinder by any suitable means, as by a pipe 24. Circulation of Water will pass through both jackets and exhaust through the pipe 25. In the same view an improvement is illustrated by 'means of Which one of the joints will be dispensed With and the chance of 'leakage thereby reduced. The cover 12 in this view is shown as bearing directly against the casing 1 and is secured thereto by the bolts 8, as before described. The inner cover 6Which carries the bearing 7, is mounted Within a shoulder 26, formed u lon the inner face of the cover 12 and entire y Within the chamber 1. The covers 6 and 12 are secured together, as shown, by means of stub-bolts 27, entering 'threaded openings Within the cover 12 and passing through openings in the cover 6 and being therein set up by the nuts 28, as shown. It will be understood that the covers 6 and 12 may be iirst secured together and then the cover 12 With the other cover attached thereto applied to the casing 1.
Having now described my invention, What l claim, and desire to secure by Letters Patent, is-
'.1. A gas-pump' having an oil-chamber and a removable cover and a second cover attached thereto forming a condensing-chamber, and means Jfor removing gas from the condensing-chamber. j.
2. A gas-pump having an oil-chamber and a condensing-chamber communicating there.-
with, the said condensing-chamber having a i Water-jacket. j 3. 1n a gas-pump, having anoil-chamber j and a condensing-chamber communicating l therewith, the said condensing-chamber having la, Water-jacket communicating with the i' Water-jacket of the pump.
4. In a gas-pump, the combination of a side oi the casing, the cover carrying theother bearing, a second cover attached to the casing-cover, forming a condensing-chamber, and a Water-jacket on the condensing-chamber cover. j
5. In a gas-pump, the combination with a casing, of a bearing-supporting cover, and a condensing-chamber cover, the two covers being secured together and to the casing by bolts.
6. In a gas-pump, the combination with a casing, of a condensing-chamber cover bolted thereto, and a bearing-supporting cover, bolted to the condensing-chamber cover, and entirely Within the casLng, so that only one joint will be made, and a Water-jacket on the condensing-chamber cover, said Water-jacket communicating with the water-jacket of the pump. Y
7. In a gas-pump, the combination with a casing, of a condensing-chamber cover bolted thereto, and having a shoulder on its inner face, and an inside cover secured to the condensing-chamber cover, and engaging with the shoulder, means for removing gas from the condensing-chamber, and a water-jacket on the condensing-chamber, said Water-j acket communicating with the Water-jacket of the pump.
This specification signed and witnessed this 27th day of December, 1904.
