Description

UNITED STATES PATENT OFFICE.
VVILLIAMYPLATTO, OF POUGHKEEPSIE, NENV YORK.
ROLLER ATTACHMENT FOR ROCKING OR OTHER CHAIRS.
SPECIFICATION forming part of Letters Patent No. 466,573, dated January 5, 1892.
Application led March 19, 1890. Serial No. 344,541. (No model.)
To all whom it may concern.-
Be it known that I, WILLIAM PLATTQ, a citizen of the United States, and a resident of the city of Poughkeepsie, in the county of Dutchess and State of New York, have invented certain new and useful Improvements in a Rollei` Attachment for Rocking and other Chairs, of which the following is a full', clear, and exact description, reference being had tothe accompanyingdrawings, making a part of this specification. l
My invention -has relation to a roller attachment for rocking or other chairs by means of which the occupant of the chair or the attendant may throw the roller attachment into play for the purpose of changing the position of the chair.
The invention has for its object to simplify the construction of such attachment without in the least impairing its efficiency and to provide an attachment which will also be simple and comparatively inexpensive.
With these objects in view the invention consists in certain features of construction inafter fully described in the specification and pointed out in the drawings, in which- Figure 1 is a perspective view of the rollertruck removed from the chair. Fig. 2 is a perspective View of a chair (which in this case is shown as a rocking-chair, but which may be any other kind of a chair) to which the truck is attached, showing the truck in position to allow the chair to be rolled from one place to another; and Fig. 3 is a perspective view of an angle-plate carrying a journalstud.
A represents a rocking-chair, to the rockers of which are attachedangleplates B, each of which has projecting laterally therefrom a journal-stud b.
the inner sides'of the rockers, one near each These platesare secured to end thereof. Journaled on each stud b is a bell-crank lever C, which is held in position thereon by the nut b. These bell-crank-levers each carry on its lower limb a roller or wheel D, and the upper limbs of the forward and rear sets are connected by tie-rods F,which are connected by links E, so that the rollers are caused to be operated in unison. The rear tie-rod is provided with an upward extension f, to which is pivotally secured a rod G, which has its upper end preferably bifurcated to embrace the ears of a plate H, se-v cured to the under side of the chair, the rod O and extension fconstituting a jointed rod.
Through the ears and the members forming the bifurcated end is inserted a pivot-bolt. A handle] is secured to the extension f, by means of which an attendant may-throw the rollers into engagement with the tloor, for instance, when the occupant of the chair is an invalid; or, if desired, the rollers may be operated by the occupant by means of handles J, secured to the links and projecting upward within his reach.
Having thus described my invention, I claim and desire to secure by Letters -Patent of the United States-` The combination, with achair having journal-studs secured thereto, of bell-cranks journaled to each of said studs, each of which carries at one end a roller, cross-ties E for connecting the forward and rearward pairs, respectively, link F for connecting the forward and rearward pairs together, a jointed rod secured to the rear cross-tie and pivoted to the bottoni of the chair, and means for operating said bell-cranks to throw t-he weight 0f the chair on said rollers.
