IMPROVEMENT IN lCARPET-SWEEPERS.

Specification forming part of Letters Patent No. 184,633, dated November 21, 1876; application led October 2, 1876.

To all whom it may concern Be it known that I. SAMUEL F. LEAGH, of Chelsea, in the county ot' Sui-It'olk and State oi' Massachusetts, have invented a new and Improved Carpet-Sweeper; and I do hereby declare that the following is a full, clear, and exact description of the saine, reference vheilig had to the accompanying drawing, forming part of this speeication. l The present invention has reference to carpet-sweepers, and is designed to furnish means wherebythe brush-cylinder can be readily removed from the box or casing,.and will always remain tight and run Without noise. To this end the invention consists in the provision ot' a sliding spring-pressed center or pivot, which is iitted into a socket applied to the side of the brush box or casing, said center being adapted to receive one'end ofthe brush-cylinder, the opposite endot' which has a gudgeon or journal, which turns in a face or bearing plate applied to the brush box or case.

1n the accompanying drawing, forming part of this specitication, the casing or box A is of the ordinary construction7 and has the customary receptacles or trays for collecting the dirt swept up by the brush-cylinder C as the same revolves on the tloor. In order to retain the brush cylinder detach-ably in place, so as to enable it to be easily removed when required, I provide one end ofthe cylinder with a txed gudgeon, D, which runs in a face or bearing plate, E, applied to the side ot' the box A. rIhe opposite end ot' the cylinder runs on a center or pivot, F, titted mov-ably in the other side wall oi' the box, so as to enable said pivot to be projected and retracted for fastening and detaching the brush-cylinder. The pivot F enters a hole in a metallic wearing-plate applied to the end ot' the cylinder. A metallic socketpiece, G, having a plate or ange, l,

for securing it to the outer side ot' the box by means ot' screws, is adapted to receive the pivot or` center, and also a coiled spring, I, encircling said pivot. The spring serves to hold the pivot in engagement with the brushcylinder. The rear end ot' the pivot F extends through a hole in the closed end of' the socket, and bears a milled head, J, for grasping the pivot, to retract the same from the outside of the box.

The pivot having been retracted from the cylinder, the same can be readily removed through the top of the box, thus avoiding the necessityl of emptying the pans or spilling the dirt.

By running the brush on centers, as shown, noiseis prevented, as the bearings are always tight.v 1

A The pivots or centers are provided with pointed or conical ends, so that the brush will run easily and without iriction. The spring serves to press the center forward as it Wears away, thus keeping the brush always tight.

I am aware that brush-cylinders have been fitted on removable bearings or axes, and provided withdetacha'ble journals; but they are detective, because they are either screwed into place or held hy fastening-screws, which are liable to work loose.

Having thus described my invention, what I claim as new is In a carpet-sweeper, the combination ofthe selfadj listing center or pivot F, having spring Iand head J, with the box A, socket-piece G- H, brush C, and tixed gudgeon D, as and for the. purpose set forth.
