k llflVENTOH MM WWW mm A Qw WITNESSES single coin, I have embodied mechanism operable in connection with the poise beam, a locking device therefor, and the trip lever, whereby the trip lever will also operate to return to normal position, effecting discharge of the coin and upward movement of coin lever 27 and resulting in holding of the poise beam so as to prevent further action until the platform is entirely released from the load, or another coin deposited.

Such mechanism consists of a pendant holding or friction rod 37 pivoted to the outer end of the poise beam at 38 and hanging vertically within the casing 5 at one end thereof adjacent to the counter-weighted ends of the coin lever and trip lever respectively. At the lower end of rod 37 is a pin 39 extending between an upper tilting lever 40 and a lower tilting lever 41, lever 40 being pivoted at 42 and lever 41 at 43 on suitable s'upporting standards.

Each of said tilting levers 40 and 41 is provided with a bifurcated terminal 44, 45, respectively, the divided arms of which embrace a lug 46 and 47 at the upper and lower portions of the counterweighted end of trip lever 23.

By this means, upon the scale being in equipoise Fig. 2), and an additional weight being applied to the platform, the long end of the poise beam will rise, lifting rod 37 and thrusting lever 40 upwardly, lifting rear end 23 of lever 23 and lowering its end 23 discharging the coin and immediately allowing the coin lever 27 to rise, and lock the beam.

Said lever 27 is provided at its counterweighted end with an arm 48 adapted to engage the edge of rod 37, and to thrust its opposite edge over against an interlocking knife edge abutment 49 adapted to engage one of a series of teeth 50 on rod 37, or merely against the smooth edge of the rod. It will be understood that it is not necessary to cause a positive interlock between abutment 49 and the rod 37, so that the teeth 50 may, if desired, be dispensed with, or so designed as to interpose the necessary frictional holding engagement. Thereupon the machine will be held against further operation to register an additional weight until another coin has been deposited.

Likewise, should the first load, the weight of which has been ascertained, be partially removed from the platform for the purpose of independently weighing a lighter or heavier load, the long end of the poise beam will be lowered, thrusting pin 39 against lever 41 beyond its fulcrum 43, thus tilting upwardly the counterweighted end of trip lever 23 and lowering its other end 23 efiecting discharge of the coin and the same result.

The trip leverthus performs a double function,

When it is in weighing position, the scale being in balance, abutment 36 is sufiiciently high to stop the coin lever before the coin reaches the lower edge of the guard 31, but when the trip lever is raised at the rear end by variation of the load on the scale, the front end 23 drops, the coin lever is depressed by the weight of the coin, following abutment 36 down, until the coin clears the guard 31 and rolls out into the receptacle, releasing the lever, which returns to normal position.

The other function of the trip lever is through the coin holder, which, operating as described, rises after release of the coin, and cooperates with the controlling holding rod 37.

It will be entirely clear from the foregoing description that the scale may be used with the spring 17 in connection with the trip lever 23 and steelyard lever 6, dispensing with the levers 40 and 41 and pin 39. In such case, for ordinary weighing, the person to be weighed will step on the platform either before or after placing the coin in the chute. When the coin is so placed, the person being on the platform, the poises can be moved until the scale is balanced and the weight has been ascertained.

In such arrangement, it is only necessary to instruct the person to be weighed that he stand on the platform before dropping the coin, and in such case also the coin chute releasing lever 3435 may be dispensed with.

VJ hen the party has been weighed and has stepped from the platform, the weight being released from lever 6, spring 17 raises end 23 of trip lever 23, effecting discharge of the coin as described. With such form of construction, without levers 40, 41, there is nothing to prevent one person from keeping all or part of his weight on the platform until a second person gets on the platform, who could then weigh himself the same as the first.

lVhen the levers 40, 41, and pin 39 of rod 3? are utilized, either without the spring 17, or in combination with it as shown, trip lever 23 will be positively actuated upon any material variation of the weight on the platform, by movement of the beam 8 up or down, as described.

In such case, the instructions which may be conspicuously posted, should be that the party to be weighed stand on the platform before dropping the coin in the chute. This being done, and knowing his weight approximately, as say 165 pounds, the poise 1.0 will be set to 150 pounds. Having placed a coin in the chute, he will then adjust the upper poise 11 outwardly on its beam, and the scale, belng within 50 pounds of balance or less, and the steelyard lever having lowered, the counter-weighted end of trip lever 23 Will also fall. This moves arm 3l-35 upwardly; allowing the coin to drop; into theeoinpo ket 26,-loiwering lever 27 until it rests on abutmentfifi,as described" 5 The'coin lever: willuthusgbewheld 'n such posit-ion: While thesrpartyr; is. adjusting -.the poises -to'aseertain his .vveight.:- "*"lhe scale Willi remain free, because When the roin lever-drops .the arm 48 isuretracted, rod 37' xvill' hang 'pendentlv tree from-trio: "tion: abutment 49,;pin 3-9 will be relieved f romen'gagement with either lever 40 or 41-, when the beam is balanced, ample clearance =being providecl3 so :that the: xrod is; free, to
