UNITED STATES PATENT OFFICE.
ALBERT H. JAREOKI, OF ERIE, PENNSYLVANIA.
IM PROVEM ENT IN GAGE-COCKS.
Specification forming part of Letters Patent No. 200,396, dated February 19, 1878; application filed November 1, 1877.
To all whom it may concern:
Be it known that I, ALBERT H. JAREOKI,
of Erie, in the county of Erie and State of Pennsylvania, have invented a new and useful Improvement in Weighted. Gage-(locks; and I do hereby declare the following to be a full, clear, and exact description thereof.
My invention relates to the constructionof what are known as weighted gage-cocks, and consists in the manner of applying the packing. The packing in gage-cocks of this kind has usually been done by setting a piece of packing in a mortise in the contact-face of the weighted part. .When this piece of packing became worn it had to be picked out and Others have proxdded a slotinortise, through which a tape of packing could be pulled, so as to present a new piece of packing when the part of the ribbon lately in con tact had become worn.
My invention relates strictly to the improvement of this last-named form.
My invention is shown in the accompanying drawing by one figure, which is a longitudinal vertical section of the whole gage-cock, in which P is the plug which screws into the boiler. L is the lever, W the weight, and T the packing-tape. Mis amortise through the weight W, and by which said weight slips onto the lever L. S is a thumb-screw for securing the weight to the lever, and also for retaining in place the tape T. H is a guard or hood on the lever L, for deflecting the steam downward. E is the passage through the plug.
In outward appearance my gage-cock differs very little from others.
In my device the packing is in the form of a tape, and is concealed in a mortise in the heador weight, and thence passes upward be. tween the meeting faces of thelever and the plug, where it performs its office of a packer.
When the part of the tape in contact with the escape becomes worn by the action of the steam, the thumb-screw S can be loosened, and the tape can be pulled along sufficiently to make a new packing over the escape.
The application of a running tape in the connection shown t'. 0., between the faces of the lever and plugis not new; but to conceal and protect that tape within the weight, and the thumb-screw or similar device for retaining and adjusting the tape, I think are novel. There might be provided in the weight a ratchet arrangement, like a lamp-wick raiser, for running the tape; but I think it is not necessary. v
The advantages gained by my construction are neatness of appearance, entire protection of the tape before it is used, ease and certainty of adjustment of the packing, and a more perfect article of its kind.
What I claim as new is- In combination with the weighted handle of a steam gage-cock, a packing-tape placed within the handle, and means, substantially as shown and described, for retaining and adjusting the same.
In testimony whereof I, the said ALBERT H. J ARECKI, have hereunto set my hand.
ALBERT H. JAREOKI.
