I UNITED STATES PATENT ELNATHAN SAMPSON, OF LANSINGBRG, ASSIGNOR TO ALFRED CLARK HITCHCOCK, OF TROY, NFV YORK.

IMPROVEMENT iN WEIGH-LOCK SCALES.

Specification forming part of Letters Patent No. 57,64 i, dated August 2S, lcb.

. To all whom it may concern:

Be it known that I, ELNATHAN SAMrsoN,

of Lansingburg, in the county ot' Rensselaer and State ot` New York, have invented certain new and useful Improvements in Constructing Weigh-Lock Scales 5 and l do hereby declare that the following is a full, clear, and exact description of the construction and operation otl the same, reference being had to the annexed drawings, and tothe letters oi' reference marked thereon, making a part of this specification, in which- On Sheet l, Figure l is a side elevation of the scale-beam side ot' a center section of said weigh-lock scale, showing the arrangements and combination of the sustaining-levers and manner of connecting the cradle to said levers. Fig. 2 is an elevation ot the opposite side of said lock, showingthe arrangement and combination ot' levers on that side. Fig. 3 is a top view of the lock, and Fig. et is an end view of the saine.

The figures on Sheet 2 of the annexed drawings show in detail the manner ot' constructing, inserting', and operating the said weigh-lock scale, and in which Fig. 5 shows side elevation. Fig. 6 is an elevation ot the opposite central parts of said weigh -lock. Fig. 7 is a vertical transverse sectional view taken through the center of said weigh-lock. Fig. S is an end view, and Fig. 9 is a detached view, ot' one ot the transinitiing-knees used in connection with suitable rods arranged under the door of said lock-chamber, for the purpose of connecting the weighing devices arranged on the opposite sides ofthe lock- Walls. The remaining iigures on Sheet 2 show in -detail the manner ot' constructing the sustaining-levers, and also of the parts operating in immediate connection with them.

rlhe same letters have reference to like parts in each otthe figures.

The' nature of my invention consists in a combination of direct sustaining-levers with bell-crank levers, for the purpose ot' supporting a cradle receiving the vessels to be weighed and transmitting the weight through other levers to the scale-beam, said sustaining-levers being arranged in horizontal parallel positions to the side walls ot the lockchamber, substantially in manner as hereinafter fully described.

It also consists in a combination and arrangement ot' bell-crank levers with a transmitting-lever, substantiall)` in manner and ior the purpose hereinafter fullbv described.

lt also consists in the peculiar manner, substantiall)v as hereinafter fully described, ot' connecting the devices constituting a weighing apparatus, and arranged on opposite sides of a weigh-lock chamber, thereby doing away with the necessitiv ot' any superstructure ot frame-work or ot' buildings over and across the lockchamber, thus securing an unobstructed passage for masted vessels and steamboats through said lock.

It also consists in a combination otl certain bell-crank levers, arranged with reference to and connected with the weighing devices ot' both sides of the lock-chamber in manner substantially as hereinafter t'ully shown, for the purpose ot' transmitting the weight or load on the cradle ot' said weigh-lock to the scale-beam of the same.

It also consists in the general combinations and arrangements of the respective parts, substantially in manner as hereinafter described, the whole constituting an improved weighock scale.

In order to enable others skilled in the art of constructing weighing apparatus to make and use my improved weigh-lock scale, I will now fully describe the same, which is as tollows, viz:

A lock-chamber is first constructed, in manner substantially as shown in the annexed drawings on Sheet 2. Upon the steps H H, which project from the side walls ot' said lock-chamber are placed and secured the metal fulcrum-bearingsD D, and upon the intermediate step, H', is placed the t'ulcrum-bearing E.

C C are direct sustaining-levers, having their fulcrum points or edges constructed of hard metal in the usual knife-edged form. These levers are placed with their fulcrumedges upon their respective bearingsD D, and they are so arranged with reference to the side walls and suspended cradle ot' said lockchamber as to be substantiallvin parallel positions to said walls and cradle, in manner as show-n in Figs. l and 2 ot' the annexed drawings.

F is a bell-crank lever, duly adjusted with 2 Y sacan.

its knife-edge bearing upon the fulcrum-bearing E, which bearing is formed with an open space between its sides, so as to allow the ends ot said levers UG to pass under said bell-crank lever F, that they may be properly secured to the same by suitable links.

Suspended from said levers C C by the suspension-rods a a is the receiving-cradle J, which receives and sustains the vessels to be weighed.

The levers C Gf, when arranged in manner and connected with the bell-crank lever F as above described, and attached to the cradle `J by suspension-rods, constitute what I term a set of direct sustaining-levers when the same are employed in constructing Weigh-lock scales. As many as may be necessary of said sets of levers are employed on each side of the lock-chamber, and they are arranged, respectively, in corresponding positions directly opposite each other. The number of said sets required in a weigh-lock scale will, of course, depend upon the length ot' the lock-chamber ot1 the saine. These respective sets of levers are so arranged on the side Walls of the lockchamber that the suspension-rods et a of the cradle J may be arranged substantially at equal distances from eachother, in manner as seen in Fig. 5, Sheet 2, of annexed drawings. This manner of arrangement, as above set forth, secures a better equalization of the direct sustainingpoints along the cradles length, thereby causing the stress or weight of vessels, when being weighed, to be more evenly distributed over said bearing-points, which prevents sudden strains and liability of deran gement of the weighingapparatus.

The bell-crank levers F of the respective sets of said levers C C are connected together by means ot' connecting-rods d d,`

in manner as shown in Fig. 5; and the said sets of levers G C', or the Weighing appa` ra-tus arranged on the respective side walls of the lock-chamber, are connected together in manner substantially as follows: On the wall of said lock-chamber opposite to the scale-beam side is combined and arranged in a suitable frame, B, for supporting them, the bell-crank levers c c, said levers being' connected with levers F by means ot' rods l d, and arranged at right angles to said levers c c is the lever 17, attached to which is the connecting-rod b, which passes down through a chamber or tube formed in the side wall of the lock to the bottoni thereof, and is there joined to a counecting-knee, j', in manner substantially as shown in Figs. 7 and 9 on Sheet 2 of annexed drawings, said knee j' being connectedwith a corresponding knee, j", arranged at the bottom ot' the opposite wall, by means of the connecting-rod G, vwhich is arranged in a tube or box under the ioor ot' the lock-chainber.

To the kneef is joined a connecting-rod, g, which connects with the lever h, as seen in Fig. 7, Sheet 2, and said lever h is connected by a rod, 7c, to the connecting transmitting bell-crank lever s. Upon each side of said lever s, and arranged in combination with 1t,

are the bell-crank levers t t', which are rcspectively connected to said lever s by suitable rods or links r r, as seen in Fig. l, Sheet l, said levers t t being also respectively connected with the bell-crank levers -F F by means of rods d d. Said transmitting-lever li, connecting bell-crank levers, and levers tt are arranged and have their respective bearing-points in a suitable frame, A, in manner substantially as shown in Figs. 1, 5, and 7 in the annexed drawings.

To the upright arms of said connecting bell-crank lever s are attached rods m m, connecting, by means ot" snit-able links, with the bell-crank lever a, which connects, by means of rod l, with the scale beam L, the said scale-beam being constructed, arranged, and adjusted in a suitable manner by any ot' the known modes ot' construction and adjustment in public use that may be adapted to Weighlock scales.

Having fully described my improved Weighlock scale, what I claim as new therein, and desire to secure by Letters Patent, is-

l. The combination ot' the bell-crank lever F and the direct sustaining-levers C and C', when said sustaining-levers are arranged in horizontal parallel positions to the side Walls ot' the lock chamber, substantially as described, and for the purposes as set forth.

2. Arranged in connection with the bellcrank levers F F, in manner as described, the combination of the bell-crank levers cpc and transmitting-lever t', substantially as and for the purpose herein set forth.

3. Connecting the devices arranged on opposite sides of the lock-chamber and constituting a weighing apl'iaratus for weigh-lock scales by arranging the mechanical means employed for that purpose under the iioor of the lock-chamber, in manner substantially as herein described, and tor the objects as set forth.

et. Arranged and connected with the bellcrank levers F F, in manner as described, the combination ot the bell-crank levers t t with the bell-crank connecting-lever s, for the purpose of transmitting the weight ot' the vessel resting upon the cradle to the scalebeam, in manner substantially as herein described.

5. In combination with the bell-crank le- `vers c c and transmitting-lever i, the mannersubstantially as herein described.
