WERGHlNG TONGS.

SPECIFICATION forming part of Letters Patent No. 697,89d, dated April 15, 1902.

Application filed November 4,1901. $erial No. 80,978. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM F. SHILEY, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in W eighing-Ton gs,of which the following is a specification.

My invention consists of a weighing-scale more particularly adapted for holding ice and weighing the same, as will be hereinafter described and the novel features set forth in the claims.

Figure 1 represents a rear view of weighingtongs embodying my invention. Fig. 2 represents a side elevation thereof. Fig. 3 represents a front view of a portion thereof. Fig. 4 represents a perspective view of a dctached portion. Fig. 5 represents a front view of a modification.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates a scale which in the present case consists of a spring-balance.

B designates the slide or follower of the scale, and B the index or finger thereof, the former having connected with its lower end the link 0, from which depends the system of levers D known as lazy-tongs. The upper levers D of said lazy-ton gs are pivoted to said link 0, and the lower levers D are extended in the form of the members of a pair of icetongs E; but said members may be riveted or otherwise secured to said levers D as shown in Fig. 5. Connected with the upper end of the casing F of the scale is the handle F for carrying purposes.

G designates a sliding rod or bar which is guided in eyes H on the back of the casing F and has its lower end connected with the pivot J of the lower terminal of the lazy-tongs. The upper end of said bar is provided with the handle K, whereby said bar may be conveniently raised for the purpose of opening the tongs.

The operation is as follows: The bar G is raised by means of the handle K, as has been stated, by which provision the tongs open, as shown in Fig. 3, and in this condition are placed over a piece of ice, when the handle K, and consequently the bar G, is let go. As the handle F now carries the scale and entire load, the tongs close on and grapple the ice and firmly hold the same, it now being evident that the ice depends from the follower B and is accordingly weighed, the eX- tent of the same being read off on the graduations of the scale, and the ice may be conveniently delivered while being carried to the desired place by the scale. WVhen the handle K is again grasped and the bar G raised, the tongs open and are removed from the ice, leaving the latter free, as is evident, the parts then resuming their normal position, as shown in Fig. 1. The link 0 is of the form of a spiral or twist, so that its flatness is presented from the side to the front, thus providing a broad bearing for the pivotal connection J of the upper levers D of the lazy-tongs. When the handle K is grasped to open the tongs, the scale may be carried by said handle without necessarily changing to the bandle F for said purpose until another piece of ice is to be grasped, when said handle K is let go and the handle F is grasped, so as to carry thescale with the ice depending therefrom; but, as is evident, both handles may be grasped for most conveniently operating the tongs to be opened and directed to the piece of ice in order to have the tongs properly close thereagainst.

Having thus described. my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A weighing-scale, a handle connected with the casing thereof, avertically-arranged sliding bar mounted on said casing, a handle on the upper end of the said bar, lazy-tongs levers depending from a weighing member of said scale and having their upper axis connected with the same, and grappling-tongs connected with the lower axis of said levers, said bar being connected with said levers by said lower axis, the parts named being combined forming an improvement in weighingtongs.

2. Lazy-tongs levers, grappling-tongs connected with the lower members thereof, a weighing-scale, a handle thereon, a movable member of said scale being connected with IOU the upper axis of said levers, a sliding bar bar mounted on the scale and connected with mounted on said casing, the lower aXis of said the lower axis of said levers, said link being levers being connected with the lower end of deflected partly from its broad side presentsaid bar and a handle on the upper end of ing the same to the front where it is connect- 5 said 1351' adjacent to the handle of the scale. ed with said upper axis of the levers.

3. weighing-scale, lazy-tongs levers, a 7

link connecting the upper axis of said levers WILLIAM SHILEY with a movable weighing member of said Witnesses:

scale,grappling-tongs continuous of the lower JOHN A. WIEDERsHEIM, 10 pair of said levers, and a vertically-movable E. HAYWARD FAIRBANKS.
