Letters Patent No. 106,429, dated August'16, 1870.

IMPROVED GEAR PoR cARPETswnEPmG MACHINES'.

The Schedule referred to 4in these Letters Patent and making part .of the same.

To all whom fit may concernl .4

Be it known that I, GILBERT FtsK TAYLoR,.of the city, county, and State of New York, have 4invented va new and useful Improvement yin Gear for Carpetsweeping Machines;`and I do hereby declare th'atthe following is a full, clear, and exact description of the same, reference being hadrto the accompanying drawing and to the letters of vreference marked thereon` This invention relates to an improvement in gear for carpet-sweeping machines, for which I made application for .Letters Patent, and which was allowed November, 1869.

This machine, for which a patent was allowed, had its'driving-gear constructed entirely of India1ubber, and consisted of a driving-wheel or pinion placed. be'-` tween two traction-wheels, all being cast or moldedjn one piece.

.On testing this invention, it'was found to operate well, being nearly noiseless in performing'its work, and, with care and attention, suihciently durable. Gai-less persons, however--servantsdid, in some few instances,allow the rotarybrushfcylinder to become clicked or clogged', and while said cylinder was therc' by rendered immovable, forced the machine along on the carpet, and broke the teeth of the driving-pinion, and,.in one insta-nce, rasped. down the traction-wheels out of round.

.The object of this present invention is to obviate this ditlicnlty, provide against the carelessness of'the users, and, to this end, I construct the gear of metal and India. l'ubber combined, hai/ing the driving-wheel or vpinion of met-al, and the traction-wheels of India rubber,.'as,hereinafter fully shown'land described.

In the accompanying drawing- Figure 1 is an edge View of my invention.

l-igure 2, a section of the same, taken onthe line a:Y x, iig. 3. v

Figure A3, a side view of the same, with one ot' the traction-wheelsl removed.

Figure 4, a side view of' the detachedjtractionwheel.` i

ASimilar let-ters of reference indicate corresponding parts in the several figures;

A Brepresent the two India-rubber. 'traction-wheels,1 and l VC, the metal driving-wheel or pinion. The wheel A is cast orlmolded with a hebra, projecting centrallyfrom one side, said hub a and wheel A being castor' molded in one piece.- v

Onthis h'ub 'a 'the metal driving-.wheel or pinionv C i's placed, and .prevented from turning thereon by a. horn or projection, b, which is ttediuto theAIndiarubber hub a, as" shown clearly in Iig. 3.

The other traction-wheel Bis' alsotted on the hub a, thelatte-r passing `entirely through B, so that the Outerside of the same andthe enydgof the hub will `be `ush with eztch other.

The wheel B may be secured .on the hub and tothe side of the metal wheel or pinion C, by any suitable cement. l Y l -The metal wheel or pinion() geztrs-intoth'e pinion on the shaft of the hrusl'l-eylinders, and the India-rubber traction-wheels, ns the machine is .shoved along, communicate, through the medium ofthe-metal wheel or piniony C, the rotary motion to therbrush-cylinder.

This metal wheel or pinion G serves to protect the India-rubber traction-wheels A B, not permitting to wearmaterinlly, as the ends ot` the teeth ot-saidwheel or pinion will soon-come inl contact with the carpet, as they are'within a short distance of the peripheries of. said wheels A B.

The teeth of theJnctal wheel or pinion C, of course, will not break, nor can said ,wheel'or pinionl Work -on the hub a, and the I odia-rubber traction-wheels A B insure the rotation ofthe brush-cylinder.

Thus', by this simplearrangement, the difficulty attending'the carelessness of the users ot' my machine is fully obviated, and, at the tages retained. Having thus describetlemy l/Vhat I claim as' new, tersv Patent, is-

The metallic toothed ring C, cast with projection b, and fitted on the extensiona of rubber rim A, where it is secured bythe rubber collar or rim B, the whole constituting an improved gear-wheel for carpet-sweep ers, as herein shown and described. l

Sametime, all of its ativan-'- invention, and desire to secure by Let- Witnesses:
