ROLLING-PIIN.

SPECIFICATION forming part of Letters Patent No. 643,780, dated February 20, 1900.

Application filed June 21,1899.

To aZZ whom it may concern:

Be it known that I, GLAEENoE LESTER PITOHER, a citizen of the United States, residing at New York, (Long Island City,) in the countyof Queens and State of New York,have invented certain new and useful Improvements in Rolling-Pins; and I do 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, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to rolling-pins; and its object is to provide means for reducing v the friction incident to the use of a rollingpin to the minimum.

The construction of the improvement will be fully described hereinafter and its novel features defined in the appended claims.

In the accompanying drawings, which form a part of this specification, Figure 1 is a view in perspective of a rolling-pin embodying my invention, and Fig. 2 is a longitudinal seetional view of the same.

The reference-numeral 1 designates a roller formed with a central bore 2, extending throughout the length of the roller, and with circular end recesses 3, concentric with the bore. Within each of the end recesses 3 is secured a cup-bearing 4, having a cone-surface 5 and formed with central openings, through which extends a shaft 6. This shaft projects beyond the ends of the roller 1 to support the handles of the device, and the ends of said shaft are reduced circumferentially and screw-threaded for the purpose hereinafter explained. The shaft 6 is also screw-threaded at the points 7 for the attachment of bearing-cones 8, which latter'have cone-surfaces cooperating with the surfaces Serial No- 721,865. (No model.)

5 to form a trackway for antifriction-balls 9. The bearing-cones 8 are formed with integral squared extensionslO, which facilitate their adjustment.

11 and 12 designate the handles of the device comprising cylinders bored to fit the ends of the shaft and secured by caps 13, which are centrally bored and internally threaded to engage the threaded ends of the shaft. The caps are held in place by screws 14, which pass through openings in the caps and into the ends of the handles.

It will be apparent from the drawings that the roller 1 will freely revolve in use without revolving the handles, and, further, that the antifriction devices greatly reduce the labor of rolling dough.

I claim- 1. A rolling-pin comprising a roller formed with a central longitudinal'bore, and end recesses concentric with said bore; antifrictionrollers supported within said recesses; a shaft extending through the roller and projecting from the ends thereof; and handles fixed to the ends of the shaft.

2. A rolling-pin comprising a roller formed with a central longitudinal bore, and end recesses concentric with said bore; cup-bearings secured within the recesses; a shaft extending through the roller; bearing-cones on said shaft; antifriction rollers supported within the recesses and between the cup-bearings and cones, handles on the ends of the shaft; and caps for securing the handles to the shaft.

In testimony whereof I afiiix my signature in presence of two witnesses.

CLARENCE LESTER PITCHER.
