the chair or stool is at all times free to be shifted longitudinally of the rod 31, and the guide sleeve 42 cannot separate from the rod 31, by virtue of the-shoulder 38 and collar 39. v V l The operation of the seat or stool is as follows: When the ring is applied to the pedestal Hi, the auxiliary seat or chair may be shifted or swung circumferentially of the pedestal ID, in either direction, by the operator sitting upon the seat element 23 and engaging the floor with his feet. The casters are free to turn horizontally and renders this operation easy. The operator may shift the chair or stool generall radially toward or from the pedestal ill of the barber chair, by engaging the floor with his feet, while seated upon the seat element 23. This action is permitted by the fact that the guide sleeve 42 is permanently slidable upon the rod 31. The spring or springs 34 will yield to permit of this adjustment. These springs will return the chair or stool to the normal position when the weight is removed therefrom. v
It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size, and arrangement of parts, may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims. 7
Having thus described my invention, what I claim is: V
1. An auxiliary chair or stool for use in co nection with a barber chair having a pedestal, comprising a frame including a triangular group of upstanding upwardly converging legs connected at theirupper ends, a seat element secured to the upper ends of the legs, casters secured to the lower ends of the legs, a substantially vertical tube arranged'centrally of the triangular-group of legs, a' horizontalguide sleeve secured to the lower end of the substantially vertical tube, a substantially horizontal rod permanently slidably mounted within the guide sleeve, springs to oppose the longitudinal movement of the guide sleeve and return the same to the normal posi-.
tion when released, such springs being connected attheir inner ends to the guide sleeve and at their outer ends to the substantially horizontal rod, and a ring mounted upon the pedestal and connected with the horizontal rod. I
2. An auxiliary chair or stool for use in connection with a barber chair having a pedestal, comprising a frame including a triangular group of upstanding legs, a seat mounted upon the upper ends'of the legs, wheels secured to the lower ends of the legs, a substantially vertical'tube arranged centrally of the triangular group of legs, a horizontal guide sleeve secured. to the lower end of the substantiallyvertical tube, a substantially horizontal rod permanently slidably mounted within the guide sleeve, pins connected with the substantially horizontal rod and disposed upon opposite sides of the guide sleeve, a pin secured to the guide sleeve, and retractile coil springs secured to the pins of the substantially horizontal rod and to the pin of the guide sleeve, and a ring mounted upon the pedestal and connected with the substantially horizontal rod,
3. An auxiliary chair or stool for use in connection with a barber chair having a pedestal, comprising a frame including a triangular group vofnpstanding legs, a substantially vertical tube secured to the upper ends of the legs and internally screw threaded, a substantially vertical screw engaging within the screw threaded tube, a seat element mounted upon the screw, longitudinally adjustable leg extensions having screw threaded engagement with the lower ends of the legs, wheels carried by the leg extensions, a horizontal guide sleeve secured to the lower end of the substantially vertical tube, a substantially horizontal rod permanently slidably mounted within the guide sleeve, retractile coil springs extending longitudinally of the substantially horizontal rod, means attaching the inner ends of the springs to the guide sleeve, means attaching the outer ends of thesprings to the substantially horizontal rod upon opposite sides of the guide sleeve, and a ring to be mounted upon the pedestal and connected with the substantially horizontal rod.
4. An auxiliary chair or stool for use in connection with a barberchair having a pedestal, comprising a frame including a substantially vertical tubeand a plurality of downwardly diverging legs secured to the upperend of the tube and forming a group surrounding the tube, the legs extending downwardly below the tube and the tube being arranged centrally of the group and having its lower end terminating near the floor, casters secured to the lower ends of the legs, an elongated generally 7 radial horizontal guide member, means to pivotally mount one end of the guide member upon the pedestal so that the guide member is free to swing substantially horizontally in opposite directions, an element secured to the lower end of the vertical tube and slidably engaging the elongated guide member and permanently free to be shifted longitudinally of the guide member withinlimits, means to positively limit the outward movement of the element with relation to the elongated guide member sothat the element and guide member cannot be separated, a retractile coil spring arranged exteriorly of the guide member and beneath and in substantial vertical alignment with the guide member to be covered thereby and having one end attached to the slidable element and its opposite end attached to the guide member, a seat, and a rod carrying the seat and adjustably mounted in the upper end of the vertical tube so that the seat may be raised and lowered.
