SANDY HARRIS, OF PHILADELPHIA, PENNSYLVANIA.

Letters Patent No. 80,169, dated July 21, .1868.

IMPROVEMENT 1N WEIGHING-SGALES.

TO ALL WHOM IT MAY CONCERN:

Be it known that'I, SANDY HARRIS, of Philadelphia, in the county of Philadelphia, and State-of Pennsyl- Vania, have invented anew and improved Scale or Implement for Weighing Purposes; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings,

andto the letters of reference marked thereon, in which- Figure 1 represents a perspective view of my scale.

Figure 2 a detached view in perspective of thehinged frame or bale, to which the connecting-baror rod is attached, and

Figure 3 is a view of thelowcr end of the connecting-rod, showing its-fasteningnttachment.

The nature of myinvention consists in the empioymentofa weighted beam, in combination with a base or pedestal, constructed substantiallyin the manner hereinafter specified.

Toenahle others skilled in the art to make and use my invention, I will now-dcscribe its construction and operation.

Irr'the accompanying drawings A represents the pedestal, made as seen in fig. 1, and cast hollow, with openings, 8 8. 4 v i B designates the neck of pedestal A, which consists of two bars, cast at their inner ends with the pedestal A, and made to project outwards and towards each other, within a suitablcdistance, and there connected by an end piece. i 7

Upon the upper end ortop of pedestal A are formed t'wo nails, 0, approaching each other atabout an angle of forty-five degrees andberelled from their centre on each side from top to bottom.

1) designates the beam formed as shown in fig. 1, and connected at or near its rear end by a bar, d, the

under side'of which is made to extend below the beam, and curved or rounded thereon, as shown in fig. l, and

out or provided on its curved surface with grooves to correspond with and fitting-over the rails C"; said grooves beiizg so cut on the bar 01 oi' beam 'D'as to suit the angle of the rails, and thus allow them, when the beam is pressed down,'to accommodate'themselves to the rails C on pedestal A.

' The bar (I on its lower side is formed with a projection or shoulder, slanting outward towards the rear end i of the bcam and provided with a hole, through which passes the shank or upper end-of a weight, G, said weight being securely bolted .to the upper side of bar (I, and made to incline inwards hy mcans of theflshoulder on bar 11, it Resting against said shoulder. I

Formed or cast on the-sides of the projecting rear ends'of beam D are projections e e, bcing bcvclled on each side from top to bottom, the object of whichflwill be apparent hereafter.

F designates an indicator, secured at its inner end to thevbar d of beam D by a pin,f, and extending out through -the beam a suitable distance therefrom, and being pointed or rcduced at its outer end, as seen in the drawin s.

E is a platform, upon which is placed a metal plate for the ordinary scoop for weighing purposes to rest on.

Secured to the sides of platform E, and at right angles therewith, are the pendants g g, which are recessed at their lower ends, and rounded therein to receive the projections 42 e on beam D, and on which saidpendants are supported.

Fastened to the under side of ,the centre of platform E, and passing through it, is the connecting-rod-or barj, which is well weighted at its upper end, as seen in fig 1.

To the lower end of rodj, and on each side thereof, are secured metal platesj, which terminate in hooks, made as seen in fig. 2. It'will be observed that the front parts of these hooks point in opposite directions so as to eil'ect a secure fastening for the rod j J represents a hinged swinging frame, hinged to metal clipsj", pinned tothe 'lower'inside of pedestal A.

The outer portion of the semicircular f rame J is bent inwards, as shown in fig. 2, so as to form a recess for the reception of the hooked end of rod j, a;rod or catch passing through said recess, on which the hooks attached to rodj catch when in position;

L designates a metal plate, having the form of the segment of a circle, and having inscribed on its surface pounds and ounces, and which are pointed out or indicated by the indicator F when the scales are in operation, or anything is being weighed.

The plate L is pinned at and between the outer end of B, and formed with shoulders which rest on the upper surface thereof.

What I clainn and desire to secure by Letters Patent, is 1. The beam D, constructedsubstantially as described, in combination with the platform E.

2. The platform E, provided with the connecting-rod j, in combination with the swinging frame or bail J, operating substantially as and for the purpose set forth.

3. The pedestal A, constructed substantially as and for the purpose described.

4. The platform E, beam D, pointer F, weight G, connecting-rod frame or bail J, pedestal A, neck B, and plate L, all combined for the purpose of forming aresponding scale.
