The present inventionrelates to a self registering and ticket-distributing peoplesbalance of the kind in which the devices for registering the'weight on a ticket, forcockmg a stamping-hammer and for. e ecting the ticket are started by the dropped coin'and by the weight of the personon the platform.

The novelfeature of the present invention consists in a cocking device of the stamping hammer which is controlled bya spring barrel and is arranged in such a way that an overstraining of. the springis' revented in thecase of any irregular'handling the barrel 5.

In the drawing-13 designates the stamping hammer of a weighing and recording scale joined to the and 5, 6 a spring barrel mounted loose'on an axle 3 supported in bearings 1, 2 by a casing 26. One of these side walls of this barrel is formed like a ratchet wheel 5., while a somewhat smaller ratchet 4 having its teeth set in a contrary sense is fast on a squaredpart of the axle 3 and is worked in an anti-clockwise sense by a finger 16 provided at the end of a rod 15 attached to the platform of the scale in order to'bend the spiral spring 7 of The rod 15 as shown in Fig. 4 is attached to the one arm of a T lever 39 which is pivoted at 40 and is supporting with another arm the platform. 41 of the scale in such a manner that the loading of the platform will cause an upward movement of the rod .15 and thereby a feeding movement of the pawl 16. A stationary pawl 18 pivoted'at 17 prevents ratchet .4

from falling back and another pawl 19 provided at the one arm of an angular lever 21 blocks the ratchet 5 and extends with a lengthened part 119 and with some play behind one of the teeth of the ratchet 4. The

other arm of this lever isengaged with its cylindrically shaped end 22 in the bifurcated arm of an angular pivoted lever 24 which leans with his other arm against the finger 16. I The two face plates'of the barrel are held together by a trundle gearing formed by screw bolts 8 provided with rollers 9. Said trundles are adapted to engage the tail 14 of and loaded again.

the stamping hammer-13 pivoted on an axle I 11. Fast to the hubh of said hammer is also, an arm lOto theend of which is attached anv upwardly. directed 't'e'nsion spring 27 and y in. apdownward direction a rod-28. This rod as shown in Fig. 4is ending in a hook 34 engaging a hook 35- at the end of bar '36 suspended at-33;whichgbaris hinged to a weighted lever-pivoted at 37. Bar-1 36 will be moved sideways so as to free hook 34 from h'ook 35 when a'coin'is strikingthe 21111138 of said weighted lever. WVhile t-he hooks 34' and 35 are engaged the rod 28 maintains the hammer in its. uplifted; cocked position.

Fast to the same hublofthe hammer is also a toothed segment 29 .geared:with anothersegment 30 unto which. is attached a carrier 31 ,fadaptedto forward the, tickets into the" path' of 'the stamping hamme pj Finally loose on said aXle 11 is mounted a stationary pawl 12 having a lateral projection 25 arranged in such a way that the arm of the I stamping hammer 13 when rising will take said pawl along with it so as to disengage it from the ratchet 5. attached to one arm of the lever 21 secures the constant contact of the pawls 119 and 19. with the surfaces of the respective ratchets.

The working ofthis cocking device is as follows The Fig. 2 represents the cooked position I, A traction spring 32 of the hammer. It is supposed that the ham mer be in'its uncocked position and the balance in its position of rest. The barrel 5, 6 will be locked in this position by the pawl 19;engaging the ratchet5... Therefore if they I platform not shown, is loaded the angular lever 24 will be positioned such that the finger 16 turns the axis 3 by means of the ratchet 4 so .as to bend thereby spring 7.

The moving ratchet 4 disengages the pawl 19 from the ratchet 5- and simultaneously therewith also the finger 16"will. be disengaged from the ratchet 5' by means of the angular lever 24, while pawl 18 blocks the ratchet 4. 7

Now the barrel 5, 6 will be turned so far as the play between the stationary pawl 12 and i the next tooth of the ratchet 5 will allow and thereby pawl 19 will be raised so as to bear on a tooth of the ratchet 5" and will be pre vented thereby from falling in.' Therefore also the finger 16 will remain disengaged even if the platform would become unloaded The purpose of this ar rangement is to prevent any overstraining of the spring 7 by any irregular handling of 2.

the scale. In the lowered position of the hammer however thearm will be raised so far that the pawl 12 becomes disengaged from its engagement withthe ratchet5 by means of the projection 25 and the barrel will become operative and will turn so as to cause a roller 9 of the trundle gearing to operate the tail 14 of the hammer which will assume the posit-ion shown in Fig. 2. The

barrel will then turn until the next tooth of the ratchet 5" gets'sto'pped by the pawl 19, But 'as this pawlhas again fallen in also the :finger 16 has fallen in and likewise the pawl 12 into the ratchet 4: but vat a certain' distance from the next tooth and the tail let'will remain half-ways betweentwo rollers of the trundle gearing. f The hammer 42 will be maintained' in this cocked position by releasing means not shown and not forming part of this invention. a
