OSCAR B. BRANN, OF WASHINGTON, DISTRICT OF COLUMBIA.
WETTER AND WIPER FOR DENTAL GRINDSTONES,
SPECIFICATION forming part of Letters Patent No. 597,235, dated January 11, 1898.
Application filed July 23, 1897.
To aZZ whom it may concern:
Be it known that I, OSCAR B. BRANN, a citizen of the United States, residing at VVashington, in the District of Columbia, have invented a new and useful Improvement in letters and Wipers for DentalGrindstones; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which Figure I is a front view of a wetter and wiper for dental grindstones according to my invention. Fig. II represents the same in side elevation.
5 represents a tank for holding water.
6 is a delivery-pipe for the tank, and it is provided with a stop-cock 7, whereby the flow of water may be regulated or stopped.
S is a mouthpiece for the pipe 6. It is cupshaped, opening outward to receive a sponge 9, and it has many perforations 10 near its circumferential edge, through which a pin 11 may be inserted, crossing the mouthpiece through the sponge to retain the latter in place.
The mouthpiece S is fitted to slide telescopically upon the pipe 6 and is provided with a binding-screw 12, whereby it may be secured in any desired position upon the pipe.
The tank 5 is mounted upon trunnions 13 in two standards 14, which are provided with a heavy base-piece 15 for the purpose of bolding the whole device steady wherever it may be set upon a bench. A series of bearings 16, located at different heights in the standards 14:, are arranged to receive the trunnions 13 for the purpose of locating the tank at a convenient height relative to any grindstone, such stones being usually run in lathes and the lathes varying in height from the bench. The tank is hung to be tilted on its trunnions 13, and the trunnions may be screw-threaded and provided with binding-nuts 17 to bear upon the standards 14: and hold the tank fixed, either level or at any pitch required, to set the sponge to touch at the desired point upon the grindstone.
There is always more or less tendency of the stone in rubbing against the sponge to turn the sponge out of place, but the various holes 10 in the cup 8 enable the operator to insert the pin 11 through the sponge in such Serial No. 645,718. (No model) a direction that the sponge will hang thereon without rolling and without spattering water. A judicious choice of position for the pin will result in thorough cleaning of the stone with little wear on the sponge;
The tank located above the sponge delivers water to it by gravity, and the amount of delivery may be controlled by the stop-cock 7 with such certainty that the moisture of the sponge may be regulated to any degree from mere dampness to dripping wet, and whatever degree of moisture it is set for will be maintained as long as the supply of water in the tank holds out. If the sponge were moistened by hand and placed in the cup, it would be very wet at first and gradually become dry,
thus causing a variation in the quality and quantity of work done by the stone. By withdrawing the pin 11 the sponge is set free to be removed for cleaning or to be set so as to offer a new wearing-surface. The tank and stand may be set anywhere upon a bench to bring the sponge in contact with either the edge or face of the stone, or it may be set away when not needed. The tank may be filled at the capped inlet 18.
Having thus fully described my invention, what I believe to be new, and desire to secure by Letters Patent, is the following:
1. The combination, in a wetter and wiper for dental grindstones, of a movable stand; a water-tank hung by trunnions on the stand and having a delivery-pipe located for the delivery of water by gravity; a sponge-cup located at the delivery end of the said pipe and binding-screws upon the trunnions of the tank, substantially as described.
2. The combination, in a wetter and wiper for dental grindstones, of a water-tank pivotally mounted on a stand; a delivery-pipe near the lower end of the tank; a stop and gage cock in the pipe, a cup-shaped mouth for the pipe, having perforations around its edge, and a pin for securing a sponge in various positions in the said cup, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
OSCAR B. BRANN.

GEORGE H; TOWNSEND, JENNIE E. LITTLETON.
