WILLIAM F, SWEET, OF JACKSON, PENNSYLVANIA.

Letters Patent No. 94,925, dated September 14', 1869.

MROVEMENT IN mmcams'r'rscmm TO WEIG-HING-SCALEE {the Schedule referred to in then Letters Patent and. put of the lame To all/whom it may concern:

Be a known that ,1, WILLIAM swear, of Jackson, in the county of Tioga, and 'State of Pennsylvania, have invented a new and useful Improvement in Scales; and I do hereby declare the following to be a full, clear, and exact description of thepsame, sutficient to enable others skilled in the artto which my invention appertains, .to makeand nsethe same, reference being bad to the accompanying. drawing, forming part of this specification, in which- Figure 1 is an elevation, and

Figure 2 is a detached view of the inner end of tlie balance-bar.

Similar letters indicate like parts. in both figures.

My invention relates to improvements in scales; and consists in the employment of ahook situated in a removable frame, which may be attached to any swayheam, the pages of said hook each containing a'calendar ofthe prices at different rates perpound the article weighed will cost, the weight on the sway-bar pointing tothe price in thecalendar:

It further consists in the employment of a removable' balance-bar, which may be attached to any scale provided with a sway-bar, as hereinafter more fully set fort-h.

In the accompanying drawings- E is the hollow standard of the scalcs, its lower end resting on the platform G. r

F is a rod, passing through the hollow standard and connecting the hopper-stand B with the ordinary lever employed at the foot of the standard.

The rod F is enlarged at its upper extremity. 0,. and passes through a hole in the frame b. i

0 isa frame, pivoted at m to the arms S, on the standard E.

A is the sway-bar or beam, cast with the'fi'ame o.

By this arrangemeiit of parts it will be seen that any weight placed on the hopper-stand, will operate the sway-bar.

cis .the sway-bar weight, having a pointer, x, on its extremity to indicate the price of the article weighed.

d is the rod, enlarged at-its lower end for the reception of the ordinary slotted weights. D is a removable balance bar, the inner end of which is constructed as seenin fig. 2, in' which a and f are projecting arms, which fit over the frame 0, and are attached securely to thesaid frame by the set-screws g g.

By this arrangement the balancc-banD can be removed from the scales, and cache applied to any scales having a sway-bar.

\V is a weight on the balance-beam D.

h is a book, placed in a removable'frame, N, attached to the sway-bar by set-screws, so that the 7 frame may be attached to any scales having a swaybar.

. The book is kept partially opened by a frame, 2, resting on its edges and is attached by strings or otherwise to the frame N.

Each page oft-he book It is ruled vertically and horizontally, as seen in fig. 1.

The figures in theupper space, opposite the pointer a; of the weight 0, indicate the price of .the 'article weighed, at the price perpound,'which is shownin the upper left-hand corner of the page.

The figures in. the second space opp site the pointer indicate in like manner the price when a five pound weight is attached to the end of the sway-beam.

The figures in the third space in like manner indicate the price when a ten pound weight is attached to the end of the sway-beam.

And spaces for figures may be added to the calendar forany weight attached to the outer end otthe sway-beam.

The object of placingweights on the end of, the sway-beam is to weigh greaten'weights than could be weighed without their use.

The pages resting on the bottom of the frame N give the prices for articles weighed 'on the platform,-

while the other pagesindicate the prices for articles weighed on the sway-beam.

When the weight/W is at the outer end of the balance bar, and the weight 0 at the inner end of the sway-bar, the scales are balanced.

Having thus described my invention,

What I claim asnewgand desire to secure by Letters Patent, is-

1. The application tothe sway-beam of ascale, of a book, substantially as-described, in such a ma'nner that the weight, when the scales are balanced, shall in'dicate "the cost of the article weighed at a specified price per .pound.

2. -The removable frame N, applied to the swaybeamof a scale for supportingthe table or book h, substantially as herein described and shown.

3. The combination of the removable fiamsN and p, for supporting a book, it, and retaining it in an open position, substantially as described.

4. The removable balance-beanie D, constructed substantially as described, and capable of application to anyscale of the kind specified, for balancing the scales with a vessel thereon, which vessel is to 'contain the article purchased, before weighing the latter.

To theabove, I have signed my name, this 30th wday of March, 1869.

W. F. SWEET.
