ORGAN TREADLB.
(No Model.)
No. 293,462. PatentedPebJlZ, 1884.
UNITED STATES PATENT OFFICE.
JACOB HESSLER, OF CHICAGO, ILLINOIS, ASSIGNOR TO WILLIAM w. KIM- BALL, or SAME PLACE.
ORGAN-TREADLE.
SPECIFICATION forming part of Letters Patent No. 293,462, dated February 12, 1884.
Application filed November 2, 1881.
(No model.)
Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Cabinet-Organ Treadles, of which the following is a specification.
In the accompanying drawings, Figure l is a front View of the roller-bar of a cabinet-organ. Fig. 2 is a partial longitudinal section of the same, and Fig. 3 is atransverse section on the line as x of Fig. 2.
Similar letters of reference indicate similar parts.
In said drawings, A represents the roller-supportingbar; B B, the rollers, and 0, one of the bands passing over the rollers and carrying power from thetreadles to the bellows. The bar is cut away,so the rollersmay be sunk entirely below its upper edge, as clearly shown. and it is also passed longitudinally, for a portion of its length, over a circular saw, and thereby akerf is formed which constitutes a seat for the pivots b of the rollers. Those portions of this kerf between the pivots are filled by the pieces a, and after the rollers are in place the pivots are retained by plugs a, permanently glued in y the kerf above them. The sides of the rolleropenings approach the rollers at the pivotal points sufficicntly close to form end bearings,
as seen at o o, preventing side-play by the rollers without the use of washers or other devices for that purpose. Above and below the pivots the sides recede gradually from the rollers, whereby contact between the bands and bar is avoided except when the bands attempt to run oi the rollers, and at such times the sides of the openings serve to keep them in place.
I claim- 1. In a-cabinet-organ, the roller-bar having openings allowing the rollers to be sunk below its edge, and a longitudinal saw -kerf, furnishing a seat for the roller-pivots, in combination with the rollers having their pivots seated and secured in said kerf, and the bands passing over said rollers, substantially as specified.
2. In a cabinet-organ, the roller-bar having cross-openings for the rollers, and a longitudinal saw-kerf for the pivots, the sides of the roller-openings approaching the rollers at the pivotal points, substantially as and for the purpose set forth, in. combination with the rollers.
