Specification of Itetters Patent.

Patented July 21, 1914.

To all whom, it may concern. I

Be it known that I, CHABLEg B. Bo innr- N, acitizen of the United States, reslding at Baltimore city, State of Maryland, h invented certain new and useful Improyements in Toy Weighing-Machines, of wh ch the following is a specification.

This invention is in the nature of a toy for the amusement of children, in the form of a scale, and the object of the invention is to furnish a toy of the character specified which will be of a very simple and economical construction, while sufiiciently strong to stand rough usage by children without much liability of breakage.

With this object in view the invention" consists in the improved construction, arrangement, and combination of the parts of a toy of the specified character which Wlll be hereinafter fully described and afterward specifically claimed. I In order that the construction and operation thereof may be readily comprehended, I will now proceed to particularly describe the invention, havingreference to the accompanying drawings, which illustrate an approved embodiment thereof, in Which drawings,

Figure 1, represents a view in front elevation, Fig. 2, a vertical sectional view, Fig.

3, a horizontal sectional view on the plane indicated by the broken line 3-3 of Fig. 2,

and Fig. 4, a detail view, partly broken away,

showing the rack and lantern gear wheel of the scale.

Like reference characters mark the same parts wherever they appear in a plurality of the figures of the drawings.

Referring specially to the drawings, the

main casing or body of the scale, which is a box-like structureofsheet metal, or other I suitable material, is indicated at 5, from the rear end of which rises a vertical casing or column 6.

From the top 7 of the body 5, a bracket 8 depends into the interior of the body and at the lower end of the. bracket as at 9 is pivoted one end of a lever 10 which extends rearwardly through the body and transversely into thecolumn 6, the rear end of this lever being normally held raised to the position shown'in Fig. 2 by a spring 11 connected at its lower end 12 to the lever and at its upper end 13 to the top of the column 6.

Pivoted to the lever 10' are two flat bars after the usual manner of dial scales.

14 which pass upward through a slot in the ,top of the body 5 and support at their up- Lper ends horizontal disk or scale pan 15, the upper ends of said flat bars bein bent outward, horizontally, as at 16, on the underside of thelpan, and the ends of these horizontal portions 16 being passed through slots in the pan and bent to horizontal positions on top of the pan as at 17.

In the column 6, in front of the spring 11 1s a vertical bar 18, preferably of angle iron, one half, as at 19 resting slidably against the side 20 of the column 6 and the other half as at 21 at a right angle to the 1 first, projecting laterally 'intothe column,

parallel with the front wall 22 of the column and spaced away therefrom, and being provided, on its inner edge, with rack teeth 23 which mesh with the pins or teeth 24 of a lantern gear 25 secured on a horizontal shaft 26 ournaled in the front and back walls of the column 6.

The shaft 26 projects through the front wall 22 of the column 6 and carries, at its outer end,.an indicating hand 27 adapted, when the shaft is rotated, to travel around on a dial 28 furnished with numerals, as shown in Fig. 1, to indicate the weight of articles or substances placed on the pan.

The angle iron bar l8is pivotally connected at its lower end to the lever 10, as shown in Flg. 3, and consequently, slides vertically as said lever moves upward or downward on its pivot 9.

Usually in scales the numerals on the dial indicate units of weight, such as pounds, or the like, but this invention being a toy, for the amusement of children, the parts need not be so accurately adjusted.

In the operation of the toy, any article placed upon the pan 15 will cause the lever 10 to move downward on its pivot 9, carry ing with it the angle iron bar 18 and causing the rack teeth 23 to turn the lantern gear and shaft 26, thus causing the hand 27 to move around on the dial 28 and indicate the weight of the article on the pail,

s the lever 26 moves downward, it stretches the spring to the limit of the weight of the articles being weighed and when the articles are removed from the pan, the spring raises the lever 10, and this causes the rotation of the hand back to the 12 or zero point on the dial, as in Fig. 1.

While the construction and arrangement so I of the several parts comprised in the invention have been s ecifically described it will be obvious that s ight changes and variations may be made therein without departing from the spirit and scope of the invention.

. Having thus fully described the invention, what is claimed as new, and desired to be secured by Letters Patent of the United States, is

The combination in a scale of the character described, comprisin a casing havin a vertical column provide at its rear en a dial provided, on the front of the column, a bracket depending into, the casing, havin a lever pivoted thereto at its lower end, said lever being extended rearwardly through said casing and transversely into said column, vertical bars pivotally mounted upon said lever and extended through said casing and having a pan supported thereon above said casing, a spring depending from the top of said column, the free end of the spring being connected with the free end of said lever, a vertical bar having rack teeth provided in one of its edges pivotally mounted upon said lever, a horizontal shaft journaled in the front and rear walls of said column, and projecting through the front wall thereof, said projection having a hand afiixed thereto and adapted to rotate on said dial, a lantern gear in mesh with the mo teeth on said vertical bar, thereb rotating said hand on said dial when said ar is lowered upon said an being depressed, substantially as descn ed.

In testimony whereof I affix my signature in presence of two witnesses.
