WEIGHING-SCOOP.

SPECIFICATION forming part of Letters Patent No. 734,653, dated July 28, 1903.

Application filed November 22, 1902. Serial No. 132,479. (No model.)

To all whom} it may concern;

Beitknown that 1, JAMES S. ALEXANDER, a citizen of the United States, residing at Jacksonville, in the county of Duval and State of Florida, have invented a new and useful VVeighing-Scoop, of which the following is a specification.

The object of thisinvention is to provide a novel weighing-scoop having mechanism that will indicate the weight of material placed therein, the arrangement being such that there will be no strain upon the weighing mechanism when the scoop is forced into the material during the filling operation, said mechanism being brought into play upon lifting the scoop.

Another object is to provide an instrument of this character having verylittle friction and therefore correspondingly great accuracy.

The preferred embodiment of the invention is illustrated in the accompanying drawings and is described in the following specification. An inspection of the claims hereto appended will show, however, that the construction illustrated and described is open to various changes and modifications.

In the drawings, Figure 1 is a side elevation of the improved scoop. Fig. 2 is a vertical sectional view through a portion of the same. Fig. 3 is a horizontal sectional view taken on the line a: w of Fig. 2. Fig. 4 is a detail perspective View of the connecting-frame, and Fig. 5 is a sectional view through a portion of the same. Fig. 6 is adetail view of a simple form of gravity-resisting means that may be employed in connection with a scoop.

Similar reference-numerals indicate corresponding parts in all the figures of the drawings.

In the embodiment shown a handle member 10 and a scoop memberll are employed, which are arranged longitudinally of each other and are constructed as follows: The member 10 is provided with the usual handle 12, carrying at its inner end an enlarged casing 13, within which is fitted a boxing secured to said casing by suitable screws or other fastening devices 14. This boxing consists of spaced transversely-disposed

walls

15 and 16, connected at their edges by end walls 17, into which the fastening devices 14: are screwed. The

walls

15 and 16 are provided intermediate their edges with upright slots 18 and 19, which are preferablyin alinement. Arranged in the upper portion of the casing 13, which 22, the outer edge of which is rounded, the I inner end of said member having a backingwall 23, that preferably extends above the wall 22. To this rear wall 23 is attached a connecting-frame consisting of an upright supporting-bar 24, having feet 25 at its upper and lower ends, which are fastened to the wall 23. This supporting-bar is arranged in the boxing of the handle member, the feet projecting through a slot 18. Secured to the supportingbar are cross-arms 26, which extend into the boxing that constitutes a guideway therefor, these cross-arms carrying at their ends antifriction-rollers 27, the upper of said rollers bearing against the inner face of the outer wall and the lower rollers in like manner bearing against the opposing face of the inher wall. As a result the connecting-frame has a slidable interlocking engagement in the guideway and secures the two members of the instrument together. Journaled upon the feet 25 are other antifriction-rollers 28, which are located in the slot 18 and are arranged to bear against the edges of the same, said edges being provided with outstanding flanges 29, that also serve to stiffen the wall 15. Still other rollers 30 may be journaled upon the rear wall 23 of the-bowl member, being arranged to rest against the outer face of the transverse wall .15. Projecting from the rear face of the supporting-bar 24 is a stud 31, which extends through the slot 19 of the rear wall 16, and to this stud is fastened a link 32, Which is connected to the balance in a manner readily understood. An antifriction sleeve, as 33, may be revolubly mounted upon the stud and engagein the slot 19, as shown in Figs. 2 and 3. The balance may be of any well-known form desired, a spring gravity-resisting device being illustrated in Fig. 6.

In this structure it will be understood that the variousantifriction-rollers will have sufficient space to; freely revolve, or, in other words, should they come into contact with one wall'they will be out of contact with the other, though this play must necessarily be extremely limited to prevent looseness of the parts. When the scoop is filled by forcing into the material, it will be evident that the rear thrust will be brought against the

walls

15 and 16 and no strain will be imparted to the balance. As soon, however; as the scoop is lifted the weight in the bowl mem her will cause the same to move downwardly with relation to:the handle member and the indicator will be actuated, thus showing the amount of material in the scoop. It will be evident that this structure is very simple, and as the friction is reduced to a minimum, because of the various rollers used, great accuracy can be obtained.

From the foregoing it is thought that the construction, operation, and many advan tages of the herein-described invent-ion will be apparent to those skilled in the art without further description, and it will be'understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

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

1. In an instrument of the class described, the combination with a bowl member in the form of a scoop having an open front end and a rear wall, of a handle member located in rear of the bowl member, an upright guideway arranged on one member transversely of the instrument, connecting means rigidly secured to the other member and having a movable interlocking engagement therewith, said members being thereby relatively movable transversely of the instrument, and a scale carried by one member having a connection with the other.

2. In an instrument of the class described, the combination with a bowl member having its front upright end open, of a handle member arranged longitudinally of the bowl mem ber and having an upright guideway in its inner end, a connecting-frame secured to the rear end of the bowl member and having a movable interlocking engagement in the guideway, said members being thus relatively movable transversely of the instrument, and a scale mounted upon the handle member and attached to the connecting-frame.

3. In an instrument of the class described, the combination with a handle member having an upright transversely-disposed wall, of a movable bowl member having its upright front end open, and a frame carried by the bowl member and slidably associated with the transverse wall, being movable transversely of the instrument, said frame bearing against the wall.

at. In an instrument of the'class described, the combination with a handle member having a transversely-disposed wall provided with aslot, of a movable bowl member, and a frame carried by the bowl member and projecting through the slot, said frame having oppositely exftending outstanding portions that engage the inner face of the wall on opposite sides of the slot. 7

5. In an instrument of the class described, the combination with a handle member having a transversely-disposed wall provided with a slot, of a movable bowl member, and a frame carried by the bowl member and projecting through the slot, said frame having outstanding arms provided with rollers that bear against the inner face of the wall.

6. In an instrument of the class described, the combination with a handle member having a transverselydisposed wall provided with a slot, of a movable bowl member, and a frame carried by the bowl member and comprising an upright supporting-bar that projects through the slot, and spaced cross-arms carried by the bar and extending across the inner face of the wall.
