REGISTERING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 651,888, dated June 19, 1900.

Application filed August 19, 1899.

To all whom it may cora/cern.-

Be it known that I, WILHELM ADOLPH AUGUST RPER, a subject of the German Emperor, and a resident of Hamburg, in the German Empire, have invented certain new and useful Improvements in Registering Apparatus, of which the following is a specication.

This invention has relation to appliances for the registration of loads hoisted and carried from one point to another, as in loading or unloading the cargoes of ships, cars, or other vehicles or the displacement of goods or merchandise from one point to another, so as to obtain a correct record of the total number of loads so displaced.

The invention relates more particularly to appliances adapted to the shifting of casks, barrels, and similar receptacles of various dimensions having projecting head flanges adapted to be engaged or gripped by tongs, by means of which they are lifted or hoisted and shifted from one point to another.

The invention consists, essentially, in the combination of hoisting and shifting tongs, a locking device operating to lock the same automatically against spreading when a load is gripped thereby, an auxiliary spring and key operated locking device cooperating with the automatic lock in preventing the spreading of the tongs by an unauthorized party to release the load, and a registering mechanism operated by the load on the tongs and operating to consecutively register the loads shifted, as will now be fully described, reference being had to the accompanying drawings, in which- Figure l is an end elevation, partly in section, with the front plate of the casing removed, of a load-registering device of the type referred to, illustrating the operative appliances in their normal positions. Fig. 2 is a central vertical transverse section thereof; and Fig. 3 is a View similar to Fig. l, the tong members being broken off, and illustrating the operative appliances in the position they occupy when a load is suspended from the tongs.

The device or apparatus consists, preferably, of a circular casing g, having a hook or, as shown, a slotted lug for connection with the hoisting and shifting tackle and a circular chamber below said hook for a train of Serial No. 727,835. (No model.)

registering-gearin g of any well-known or desired construction, f indicating the prime mover-namely, a ratchet-wheel engaged by an aetuati'ng-pawl carried by a lever n, fulcrumed at a suitable point in the casing and connected by a rod m with the support for the gripping-tongs, so that whenever the said support moves away from the ratchet-wheel fthe pawl imparts to said wheel a partial rotation, 'which is transmitted to the train of registering-gearing in a well-known manner, while when said support moves toward the ratchet-Wheel f the pawl will ride idly overthe teeth of said wheel in a Well-known manner.

The support for the tongs CZ consists of a bar a, which is preferably slotted vertically, the upper Wall of said slot seating on a suitable spring c, and h is a pivot-pin lying across said slot, on which pin the members of the gripping-tongs d are pivoted.

The supporting-bar a has motion vertically in casing g, which motion is limited by suitable abutments, conveniently by forming vertical recesses g in the proximate faces of the front and back plates of casing g, in which recesses the bar a is fitted to slide vertically in opposite directions to the required extent.

From the lower part of the casing g, in the vertical axial line thereof, projects a lockingtooth 7c, adapted to engage locking devices organized to lock the gripping-tongs d against spreading. These locking devices should of course be so organized as to be capable of locking the tongs d against furtherspreading Whatever the distance between the grippingjaws ot' said tongs may be, or, in other words, to lock the tongs against further spreading whatever may be the length of the caslc or barrel held thereby in order that the apparatus may be" used in shifting casks, barrels, bales, or the like of any capacity or diameter. To this end I provide each member of the gripping-ton gs d with a segmental rack 1,', said racks converging and having the fulcrum-pin h for center. It will be obvious that the'racks t' will move reciprocally with their respective tong members, and when the latter grip or are engaged with the head-flanges of abarrel or cask and the apparatus is hoisted the weightV on bar a will draw the latter down against the stress of the supporting-spring c sufficiently far to bring both segmental racks IOO into engagement with the single lockingtooth 7c, thus preventing the tong members d from accidentally spreading and releasing the load. This downward movement of the tongsupport d also imparts a partial rotation to the ratchet-wheel f through the means hereinbefore described. It will furthermore be obvious that if a load were lifted sufficiently to impart the aforesaid partial rotation to the ratchet f, whereby the load so lifted is registered, and said load were lowered to its support before shifting and then again hoisted, any number of loads not shifted could be registered. To avoid such a fraud, I provide a spring and key operated locking-bolt b, arranged within the casing g to be moved by its spring over the upper face of the support a for the tongs d the moment the latter has moved down clear of said bolt.

The relative arrangement of the lockingbolt Z), the locking-tooth k, and the lockingsegments t' t' is preferably such that as soon as the support d has moved down under its load sufficiently to bring the segments 'it' into engagement with thc tooth 7c the said support will also have moved clear of the bolt b, causing the latter under the stress of its spring to move into the path of the support, and thus locking it against upward movement, the casload has been shifted and lowered to the' ground or other support and the bolt l) moved out of the path of the support a the tong members are free to spread and release the load, whereupon the spring c will move said support back to its normal position, Fig. l.

It has been hereinbefore stated that the vertical movements of the support a in either direction are limited. This is necessary in order to prevent the pawl-lever n from being raised to such an extent as to throw its pawl out of engagement with the ratchet-wheel f by the upward movement of the support a, while it is necessary to limit the downward movement of the support so as to prevent the load from being supported by the lockingtooth 7c. This is effectually attained by I[he recesses g in the casing hereinbcfore referred to and would be equally as effectually attained by any other form of abutments. I prefer the recesses, because they form at the same time a guide for the support a and insure its correct rectilinear movements.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-
