CONVEYER Filed June '9, 1931 2 Sheets-Sheet 2 f5 77 v 4 56 n {A Patented Jan. 23, 1934 UNITED STATES CONVEYER Louis E. Dupuy, Syracuse, N. Y., assignor to The Lamson Company, Syracuse, N. Y., a corporation of Massachusetts Application June 9, 1931.
11 Claims.
This invention relates to an improvement in conveyers and more particularly to conveyers having a continually traveling means by which articles are transported from a despatching sta- I tion to a plurality of receiving stations and mechanism for stopping the travel of such means upon the arrival of an article at its destined station.
The primary object of this invention is broad- 1y to provide, in a conveyer of this type, means at each receiving station which means, when engaged by a transported article, will stop the travel of the transporting means, each such stopping means being so positionedthat it will be en- 'gaged only by articles located on the transporting means in a predetermined position.
Further objects of this invention reside in the details of construction of such stopping means, in the provision of locating means at the despatching station and the details of such locating means and in other features which will be apparent from a consideration of the following description and of the accompanying drawings in which:
Fig. 1 is a front elevation of a portion of an elevator well having two shafts therein the conveyer raising articles through one at the left and lowering articles through the one at the right;
Fig. 2 is a sectional view of the shaft at the left of Fig. 1 taken along the line 2-2 of Fig. 1;
Fig. 3 is an enlarged plan view of the loading platform at the despatching station; and
Fig. 4 is a sectional view taken along the line 4-4 of Fig. 3.
This invention is illustrated as employed in a conveyer of the general type shown in the patent to Gibbs, No. 1,504,886 dated August 12, 1924, operating in a well 10 having two shafts the articles being raised in the shaft 11 and lowered in the shaft 12. The conveying means comprise chains 13 and flights 14 mounted upon the chains and upon which the loads are supported, the chains being driven by an electric motor (not shown). Such loads are here indicated as trays 15 adapted to contain articles, as for example, dishes or food when used in restaurants, hotels, institutions and the like.
In the installation here. illustrated the trays are transported between stations A, B and C, at each of which articles are despatched and received through openings 16, 16, 17, 17 and 18, 18 respectively. At the station A is mounted a despatching platform 20 one end of which projects through the opening 16. The platform 20, as shown particularly in Figs. 3 and 4 com- Serial No. 543,061
Mounted for movement longitudinally of the platform is a stop 28 which rests upon and travels over the horizontal flanges 27 of the strips 21. The stop 28 is here shown as L-shaped in cross section having a vertical portion 29 and a hori- 7 0 zontal portion 30. Secured to the portion 30 is a plate 31 which substantially fills the space between the flanges 27 and a plate 32 which extends below the flanges 2'7, the plates 31 and'i32 coactingto guide the travel of the stop and prevent its separation from the platform. The stop 28 is actuated by a link 33 connected at one end by a yoke fitting 34 to an arm 35 and at the other end by a yoked fitting 36 to the plate 31. The arm 35 is fixed upon a suitably mounted '80 rock shaft 37 to which is also secured an arm 38, connected by a link 39, through fittings 40 and 41, with a treadle 42 mounted upon a supporting bracket 43. Fixed in the cross strip 22 is a threaded rod 44, adjustably secured therein by nuts 45 and adapted to contact with the portion '29 and limit the advance movementof the stop 28. The stop 28 is normally held in the advance position shown in full lines in Figs. 3 and 4 by aspring 46 suitably connected at one end to the channel bar '25 and at the other end to a tongue 4'7 which projects downwardly from the fitting 36, and is retracted therefrom by depressing the pedal 42. The flights travel continually, controlled of course by buttons 50 at each station, 9 and in order to stop automatically the travel when the tray 15 leaving the platform 20 arrives at the station to which it is destined, there is provided in the well at each station a circuit breaker which will be tripped by the tray upon its arrival at the destined station to-open a circuit and stop the motor. These circuit breakers, see Figs. 1 and 2, are designated as '51 and 52 each comprising a housing and an arm projecting therefrom and adapted to be tripped bycertain trays. The arm 53 of the circuit breaker 51 is much shorter than the arm54 of the circuit breaker 52 and accordingly will not be tripped by trays the inner edges of which travel in the path 55, designated by a dot'and dash veyer stopping means at such station.
line, but will be tripped by trays the inner edges as a matter of precaution a circuit breaker 57 the arm 58 of which will be tripped by a tray, which has been engaged by the conveyer flights and lifted from the platform 29 before reaching its proper position, to stop the travel of the conveyer.
The stop 28 limits the advance of the articles over the platform and accordingly predetermines the locations the articles will assume upon the conveyor flights. This location of the articles upon the conveyer flights is an essential feature of this invention since it determines the destinations of the articles. In other words when the stop 28 is in its normal position the inner edge of the article follows the path while when the stop is in the retracted position the i ner edge of the article follows the path 56. Conse quently if a tray 15 is to be despatched from station A to station B, the stop 28 of the loading platform is'in its normal position. shown full fed into contact therewith shown in dotted lines in Fig. 4. That'tray, will in its travel pass the arm 53 of the circuit breaker 51 and trip the arm 54 of the circuit breaker 52 and stop the conveyer until the tray is removed through the opening 18, of station C. In addition to the two delivery stations B and 0 here shown otherstations could be provided and the stop 28 given ad- ,ditional positions each position locating the tray so that it will not trip the arm of a circuit break or until it arrives at its destination.
While one embodiment of this invention has been described in detail and one application thereof has been set forth it will be understood that I am not limited thereto and that other'embcdiments maybe made and other applications employed without departing from the. spirit and scope of the invention as set forth in the following claims.
