FREDERICK SNYDER, OF LANCASTER, PENNSYLVANIA.

ELEVATING PLUMBING-BASE.

SPECIFICATION forming part. of Letters Patent No. 393,403, dated November 2'7, 1888.

Application filed December 5, 1887. Serial No. 257,003. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK SNYDER, of Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Elevating Plumbing-Bases; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to plumbing-blocks of the kind in which an upper part is vertically adjusted by screw-threads with respect to a lower part on which it fits. Heretofore these devices have not adequately provided for any other adjustment besides that in a vertical direction.

The object of my present improvement is to remedy this defect,and consequently lessen the strain on the screw-threads. To eifect this, I provide the vertically-adjustable upper part with an upwardly-extendingjournal-pin, and combine therewith a disk or platform having a downwardly-extending tubular boss, which is sleeved loosely about said journal pin and allows the disk or platform to rock, to allow the support or article mounted on said platform to maintain its top in a horizontal position, notwithstanding any slight inclination of the parts A and B.

Figure 1 represents a perspective view of the base complete, showing the foot of a stove resting on the circular disk; Fig. 2, a longitudinal sectional elevation of Fig. 1, showing the construction and adaptation of the several combined parts to each other; Fig. 3, a side elevation of the spanner-wrench,by which the central cylinder is rotated around the inverted cupbase.

In Fig. 2, A represents the inverted cupbase. In the center of its top is an opening, a, which is tapped to receive the threaded stud a. This stud is rigidly attached to the under side of the head B of the inclosing-cylinder B. Such being the case, it is obvious that if said cylinder B is revolved to the right or left it will cause the stud a to screw in or out of the base A at a, thus providing the central cylinder, B, with a vertical adjustment to any de- 5o sired position on the cup-base A. The cylinder B may be provided with a set-screw, b, to

lock said cylinder in position on the base A when onee adjusted; also, with one or more openings, 1), to receive the end 0 of the spanner-wrench O, by which the cylinder B is re U volved, which is only necessary for heavy objects. For light raisingsuch as stoves,&r'.'

it can be operated by hand with case. On the upper side of the head B of said cylinder B rests the disk D, which is provided with a boss, a, around its central opening. This is the only portion of the disk D intended to come in contact with the head B, its outer edge being entirely clear of the head B, and itscentral opening fitting loosely to the journal-pin d, which is integral with the head B. A rocking motion is thereby provided for the disk D, allowing it to adjust itself to any unevenness of the floor or the object resting on it, which in this case is the foot F of a stove.

Having thus described my invention,its operation is as follows, supposing the object to be raised and leveled a stove: I place one of the blocks, as shown in Fig. 1, under each of thefeet. Thenbymeansofthespanner-wrench c raise or lower the central cylinder, B, by revolving the same to the right or left, this op eration screwing or unscrewing the threaded stud a from the base A, as set forth. The before-described rocking motion of the disk D allows theseveral combined parts to automatically adjust themselves to any unevenness of the floor or the object resting on them, substantially as set forth.

I do not limit myself to the particular construction of the several combined parts as shown, as my invention involves a radical departure in the construction and principle of operating elevating bases or plumbingblocks, the invention consisting, broadly, of a base or block provided with a vertical adjustment for height and an adjustment by which said base automatically adapts itself to any unevenness of the door or the object resting upon it.

I am aware that it is not new to combine a centrally-screw-threaded base with an upper part or platform inclosing the same and having a screw which engages with the central screw-th reads of the base, the said screw being provided with arounded enlargement, which fits into a corresponding recess of said upper part or platform,and allows a certain amount of rocking motion to the latter, and to any journal and an annular boss surrounding it thing supported thereon. This construction resting on said time and being free to rock, and combination I do not claim; but, i Substantially as set forth.

Having thus described myinvention, what I In testimony whereof I have hereunto sub- 5 claim as new, and desire to secure by Letters scribed my name in the presence of two sub- 15 Patent, isscribing witnesses.

In combination with a fixed base, an upper FREDERICK SNYDER. part vertii-ztlly adjustable thereon and prolVit'nesses: vided on top with a central journal-pin, and a A. F. SUENCK, 1o disk liuviug a central opening to receive Said I I). ll. 1(ULIP.
