SPECIFICATION forming part of Letters Patent No. 732,100, dated June 30, 1903. Application iiled October ll, 1902. Serial No. 126.917. (No model.)
T0 all whom, it' may concern:
Be it known that I, JAMEs MORGAN, a citizen ot the United States, residing at West Philadelphia, in the city of Philadelphia and State 0f Pennsylvania, have invented a new and useful Improvement in 'longs, of which the following is a specification.
My invention is an improvement in tongs, and has for its object to provide a convenient and handy device of this character which can beused fora varietyof objects and which will be adapted for work where a tighter grip is required than can well be had with tongs of the ordinary construction.
The several features of my inventionare described in the following specification and shown in the accompanying drawings, in which- Figure l is a perspective view of a pair of tongsadapted for plumbers use. Fig. 2 is an enlarged detail view, partly in section. Fig. 3 is a section drawn through one of the legs of the tongs. Fig. 4.- is a modification showing the device adapted for use as a fruitpicker.
In carrying out my improvement I utilize a circular base-plate A, centrally perforated and having an integral upwardly-extending sleeve A, laterally slotted at A2 and open at each end. An annular flange A3 terminates the upper end of the sleeve. Sliding in this sleeve and extending both above and below it is the rod B, threaded in its upper portion. At its upper end the rod carries a cap B and ring B2, and a iiy-nnt Bsworks on the threaded part ot the rod.
The plateA carries two oppositely-disposed pairs of lugs A4, and pivoted between each pair of lugs is a tong-leg O. Midway the length of these tongs a shoulder C is formed, and the inner face of the tongs is recessed adjacent the shoulder, as shown at C2. Below the shoulder vthe tongs are concave in cross-section, as shown at C3, Figs. l and 3. Atogglejoint D is pivotally connected to the lower end of the rod B and also pivotally connected through the link members D to the tongs C at the recesses C2. The rod B is recessed at B4, said recess being adapted to register with the slot A2, and a spring B5 is secured in said recess.
In Fig. 4 I have shown a somewhat similar construction, the iiy-nut being omitted, and at the ends of tongs E are positioned baskets E', formed of wire network and braced by the ring E2 and arc E3. A cutting-blade E4 is formed at the upperside of each ring. The operation of this device will be readily seen from the drawings.
The operation of my improved tongs is as follows: The spring B4, projecting through the opening A2, will hold them in a closed position, so that whenA carried by the ring the tongs will not Hy apart nor strike together. By pressing in the spring and pushing the cap toward the sleeve the rod will slide inward, forcing the tongs apart by means of the toggle-joint D. By pulling on the ring the tongs will be drawn together, and by turning the iiy-nut down against the iiange A3 considerable gripping force may be secu red.
Having thus fully described my invention, what I claim as new, and desire to secure hy Letters Patent, is-
1. The combination with a circular, perforated plate, a sleeve carried on the plate and laterally slotted, a rod threaded at its upper end adapted to slide through the sleeve and plate, a spring carried by the rod and adapted to engage the slotted portion of the sleeve, tongs pivoted tothe plate, and a toggle-joint connecting the lower end of the rod and the tongs.
2. The combination with aplate having an opening and a slotted sleeve carried by said plate, of tongs pivoted to the plate, a rod passing through said plate and sleeve, and having its upper end screw-threaded, a link connection between the lower end of the said rod and tongs, a nut on the screw-threaded end of rod, and a catch connecting said rod and sleeve.
The combination with a plate having an opening and supporting a slotted sleeve, of tongs pivoted to said plate, a rod passing through said plate and sleeve, a link connection between said rod and tongs and a catch on the rod to engage the slot inthe sleeve to lock the tongs in a closed position. i
