SCALE.

Specification of Letters Patent.

Patented Nov. 17, 1908.

Application filed November 6, 1907. Serial No. 400,939.

To all whom it'may concern:

Be it known that I, BENJAMIN D. EMAN- can, of Indianapolis, county of Madison, and State of Indiana, have invented a certain new and useful Scale; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in

which like letters refer to like parts.

The object of this invention is to improve means in scales for'n'iaintaining the platform thereon in a truly horizontal position during the vertical movements thereof when the load is deposited thereon and removed. 01' to state it in another way, my invention causes the horizontal platform in scales tomove in a direction that is truly vertical. This object has been accomplished by guides and guide rods and other means below the platform and on a lower level than the platform and lever.

My invention relates to means secured to the platform and extending to a point above the weighing lever at which point it is guided in its vertical movement, said means being entirely free from connection with anything else, whereby it properly accomplishes the object desired.

The full nature of my invention will be understood from the accompanying drawings and the following description and claim:

In the drawings Figure 1 is a central vertical section of a pendulum scale, many elevation. Fig. 2 is the same view of certain parts of what is shown in Fig. 1 in their position when the platform is depressed.

There is shown herein a pendulum scale in which there is a base 10, a casing 11', and a plaform 1-2 riding upon the outer end of a lever 13 fulcrumed between its ends upon the pivot point 14 and carrying a scale beam 15 by means of the cord 16 secured to'and operatingover the disk 17 tending to draw and hold the indicating bar 18 at zero, said indicating bar being oscillatory on the stand 19 and being actuated by the pendulum weight 20 when relieved by the application of a load on the platform. Above the platform there is a chart 21 containing suitable indicating numerals.

I. do not wish my invention to be limited to any particular construction of scales wherein it is desirable to maintain a verltically movable platform in a truly horizontal position.

To the bottom of the platform I rigidly secure the guiding arm 25 above the lever 13 and ilrextends horizontally into the easing and is turned upward to a vertical position and at its upper end, considerably above the lever 13 and at a level higher than the platform to the link 26 pivotally connected with the'bracket27 secured to the casing 11.

the vertical movements of the platfornuwill; maintain it in a horizontal position as the lever-1s iigidlxsecufed to the platform, and with said platform and guide bar 25 will have a truly vertical movement at all times. This vertical movement is not affected by the arcuate movements of the connecting bar 26, because whatever effect the said movement would have upon the inner end of the guide It is obvipus that this guide bar 25, during bar 25 would be ofiset by a corresponding I arcuate movement of the platform in its vertical movement. This results because the length of the connecting bar 26 between its pivots is the same as the distance between the pivots on the lever that supports the latform, and that supports the lever 1'3- an the portion of the lever 13 between,said pivots has the same oscillatory movement as the connecting bar 26.

What 'I claim as my invention and desire to secure by Letters Patent is:

A computing scale including a casing, a lever pivoted between its ends with one end weighted and projecting into said casing, a load receiving platform mounted on the other end of said lever, indicating means, a connection between the indicating means and the weighted end of said lever whereby said lever will control the action of said indicator, a check bar rigidly secured to said platform above said lever and projecting into said casing with its inner end turned upwardly, and a link pivotally connected at one end with the upper end of said check bar and at its other end with said ca the. my signature in the pi'esence of the witnesses length ofh saiiink geing sughstafia y th; herein named. -same as t e nee etween e crum o i said lever and the fulcrum of said platform, BENJAMIN E 5 substantially as and for the purpose set Witnessesz' forth. j Jams D. HOPPER,

In witness whereof, I have hereunto aflixed F, H. Tnmnm.
