Specification of Letters Patent.

Patented Feb. 23, 1915..

Application filed September 18, 1914. Serial No. 862,389.

' 2 a all whom it may concern:

and useful Slate-Lorry, of which the follow- 1 ing is a specification.

The device forming the sub ect matter of this application is a lorry or conveyer adapted to be employed for handling slate in connection with ntiining operations and under other oil-cums nices in which a. device of the type hereinafter described may be useful.

One object oi present invention is to provide a novel means whereby through the iustrumentality of? a single element, the gate latch and the gate may be controlled.

Another object of the invention is to provide novel means whereby the gate latch and the gate of the receptacle may be operated, irrespective of the position of the receptacle, when the receptacle 1S rotated to discharge either irifront or at one side of the truck on which the receptacle is rotatable.

Another object of the invention is to prride a device of this type in which all of the controlling mechanisms may be handled 3 by a single operator without changing his position materially upon the support ng truck.

It is within the scope of the inventionto ii'nprovc generally and to enhance the utility of devices of that type to which the present invention appertains.

which will appear as the description proreeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed canbe made within the scope of what is claimed without cleparting from the spirit ofthe invention In the accompanying drawings z-F1gure 1 shows the invention inside elevation, parts being broken away; 'Fig. 2 is an end elevation; Fig. is atop plan.

in carrying out the invention there is pro- \idcd. a truck 1 of any desired form and embodying a main frame 2 carrying wheels :ulapted to traverse a track. The main frame 2 of the truck 1 supports a platform 4.

The invention comprises a. suitable means 5 for: controlling the brake (not shown), a controller 6 and other appurtenances usually iound upon devices of this type, the elements in question being so located that theymay be manipulated conveniently by a person standing o'nfthc rear portion of the platform 4:; Supported by the main frame and located adjacent the forward end of the machine is an annular track 7 uponwhich is rotatable a turntable 8 journaled on an uptstanding tubular shaft 9 connected at its lower end with the annular track 7 or with any appropriate or convenient portion of the main frame 2. Hinged as shown at 10 to the turntable 8 is a receptacle 11, the bottom 12 of which is downwardly and forwardly inclined. llhe position of the bottom 12 of the receptacle 11 with respect to the horizontal is adjusted by means of a turnbuckle 14 or an equivalent structure forming an operative connection between the receptacle 11 and the turntable 8, as clearly shown in Fig. 1. [i

Mounted on the receptacle 11 adjacent the forward end thereof are bearings 15 in which is mounted to rock a horizontally disposedshaft 16. Secured as shown at 17 to the shaft 16 is a vertically swinging gate 18-,

constituting'a closure for the forward end yoke 24 carrying a fulcrum pin 25 upon which is pivoted intermediate its ends, for swinging movement parallel to the gate 18, a latch lever 26. One end of the latch lever 26 is adapted to look behind the lip 23 of the keeper 21 when the said end of the latch lever moves upwardly, and the other end of the latch lever-is adapted to lock behind the lip 22 on the keeper 20 when the said end of the latch lever moves downwardly, all of which will be obvious from Fig. 2. The upper edges of the keepers 29 and 21 are beveled as shown at 27, so that when the gate 18 moves downwardly to a closed position, the latch lever 26 will engage automatically with the keepers 20 and 21. Secured to one end of the shaft 16 which supports the gate 18 is a rearwardly extended crank arm 28.

Mounted upon the platform 4 adjacent the rear end of the machine is a supplemental frame 29 in which is journaled a horiwardly in tangential contact with a horizontally disposed idler 37 supported upon a standard 38. Thence, the said end of the flexible element 36 passes about a vertically from the idler'40 and is trained in one d1 20 rection around the drum 35 onthesha'ft'34. The other end of the flexible element 361s";

trained upon a horizontally disposed idler 39 mounted similarly to the idler 37. From the idler 39 the said end of the flexible element 36 passes about a vertically disposed idler 42 upheld for rotation on a standard 43 and from the idler 4:2, the end under consideration is trained about the drum 35 in an opposite direction to that end of the flexible element which extends upwardly from the idler 40.

From the foregoingit will be obvious that the flexible element36 may be actuated by a gear train comprising the shaft 30, the pinion 32, the gear wheel 33, the shaft 34 and the drum 35 to rotate the turntable 8 and consequently to effect a swinging of the receptacle 1-1 in a horizontal direction, either to the right or to the left of the line of advance of the truck 1.

Journaled in the supplemental frame 29 is an actuating shaft 44, rotated by a crank 45 or the like; the shaft 44 carrying a p1nion 46'meshin into agear wheel 47 secured to a shaft 48 ]0llII1-Ll8d ln the supplemental frame 29. Secured to the shaft 48 is a drum 49 to which is secured one end of a flexible element 50. From the drum 49, the flexible element '50 extends downwardly over an idler 51 supported for rotation on a standard 52. From the idler 51, the flexible elen e nt 50 extends forwardly in a horizontal direction across the upper edge of an idler '53, the idler 53 being vertically disposed and being journaled on the machine frame. Thence, the flexible element 50 extends downwardly and toward the longitudinal center of the machine around an idler 54, journaled for rotation on the machine frame and inclined with respect to the horizontal, as Fig. 1 will clearly show. From the idler 54, the flexible element 50 extends upwardly around a vertically disposed, frame journaled idler 55, the flexible element passing thence upwardly through the tubular shaft 9 and around an upright idler 56 journaled on an angle bracket 57 secured to the bottom 12 of the receptacle 11 and extended transversely of the receptacle. From the idler 56 the flexible element 50 passes around an idler 58 journaled on the laterally protruding end of the angle bracket 57 and from the idler 58 the flexible element extends upwardly around an idler 59 journaled on the rear end of the crank 28-on the shaft 16. From the idler 59 the flexible element extends over an idler 60 carried by the shaft 16, theextremity of the flexible element 50 .beii'igdownwardly prolonged and being ania: disposed idler 40 journaled on a standard 41 carried by the platform 4. The said end of the flexible element is extended upwardly j The" flexible element 50 may be reeled in ',through-, .t;he medium of a gear train comprisin wheel e shaft 44, the pinion 46, the gear the shaft 48 and the drum 49. Whenv the flexible element thus is actuated, theilatch lever :26 is tilted on its fulcrum 25 so? a s'f .to"disengage the opposite ends of the latch lever simultaneously from the keepers 20 and 21. A continued pull upon the flexible element 50 will effect a downward swinging movement of the crank arm 28 and a consequent rotation of the shaft 16, the gate 18 being swung to an open position. A single operation, therefore, serves at once to unlatch the gate 18 and teswing the same to. an open position. When the flexible element 50 is slacked away, the gate 18 will swing downwardly into the closed position shown in Fig. 1, the opposite ends of the latch lever 20 traversing the beveled edges 27 of the keepers 20 and 21 and ultimately interlocking with the lips 22 and 23 of the respective keepers in a manner which will be entirely obvious when Fig. 1 is compared with Fig. 2.

It is to be observed that the construction of the operating means is such that the gate may be swung to an open positinn and be closed, irrespective of the angle defined by the receptacle 11 and the line of advance of the truck, the gate operating means being effective when the receptacle discharges toward the front of the machine 'or laterally toward the sides thereof, it being possible to swing the conveyer to one side or to the other by manipulating the tu. .table 8 from the shaft 30 and attendant mechanisms, in the manner hereinbefore set forth. Noting particularly Fig. 3 it will be seen that all of the various initial elements whereby the operator controls the movement of the actuated parts are located in compact form near the rear of the platform 4 and within the reach of the operator.
