UNITED STATES PATENT OEEICE.
ORIN' SVEET AND MERRILL E. HICKS, OF PROVIDENCE, RHODE ISLAND.
IMPROVEMENT IN PACKING FOR ROTARY PUIVIPS.
Specification forming part of Letters Patent N0. 37,015, dated November 25, 18l'2.
To all whom it may concern:
Be it known that we, ORIN SWEET and MER- RILL E. HICKS, ofProvidence, county ofProvidence, and State of Rhode Island, have invented anew and improved packing forengines and pumps and a novel mode ot' adjusting said packing to keep the engines and pumps watertight; and we do hereby declare that the following is a full and exact description ofthe said packing and of the mode of adjusting the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
In the accon'lpanyiug drawings, Figure l is a longitudinal View of the inner surface of the head of an engine,showing the packing-rings. Fig. 2 is a longitudinal View, with the packing rings removed, showing the arrangement for adjusting the rings. Fig. 3 is atransverse section showing the threads cut upon thehuhs upon which work the cog-wheels. Fig. 4 is a reversed longitudinal view showing the shaft which works the small cog.
The nature of our invention consists in inserting two rings of bronze metal into the head ofthe engine, which has been prepared to receive them, and the arrangement for adjusting the packing. These rings (marked A A in Figs. l and 3 of the accompanying drawings) are of bronze metal, ground to fit tightly into the head, and present a smooth surface of harder metal to the surface of the pumps. These rings or packing is adj usted in the follow. ing manner: They are fitted upon two cogwheels, (marked in Figs. 2 and 3 D D,) which cogs are made to work upon threads E E, in Fig. 3, out upon the hubs, (markedBB.) Of the threads marked E E in Fig. 3, one is right hand and the other is left hand, thus causing the cog-wheels to move in opposite directions. These cogs (marked in Figs. 2 and 3 D D) are made to revolve by means of a small cog-wheel (marked in Fig. 2 X) which works into one of the large cogs, as is shown in Fig. 2. This small cog is made to move by applying a wrench to a shaft (marked in Fig. 4 Y) running through the small cog and projecting from the outside of the head of the engine or pump, as is shown in Fig. 4. Thus by applying power to the wrench placed upon the shaft Y the small cog X is made to revolve, which causes the large cogs D D to re volve, by means of which the bronze-metal rings are pressed ont and forced against the opposing surface of the pump, making them watertight.
Vhat we claim as our invention, and desire to secure by Letters Patent, is
The insertion of the bronze-metal rings into the engine-head, and the peculiar mode, by means ofthe cogwheels,of adjusting the said rings,which serve as a packing for the pumps or engines, producing the effect of keeping the pumps or engines Water-tight.
ORIN SVEET. MERRILL E. HICKS.
