ELEVATOR.

Application and December 2o, 1926. serial No. 155,922.

This invention relates particularly to that type of elevators used in raising earth, grain, coal or any other similar type of materials and discharging the same at a given height.

It is one object of the present invention to provide a means whereby the elevator buckets or carriers will be automatically dumped at a given point on their upward journey without the necessity of providing means for inverting the said carriers.

It is another object of the invention to provide a structure of the character indicated that will effectually empty each carrier as it passes a predetermined point in its upward path of travel, and one that will be economical to manufacture, simple in construction, and highly eiicient in its practical application.

In the drawing:

Figure 1 is a front elevation of the struc, ture.

Figure 2 is a view on line 2 2 of Figure 1.

Figure 3 is a view on line 3 3 of Figure 2.

Referring now more particularly t the drawing, I show at 1 the front wall of an elevator enclosure, and at 2 2 the side walls thereof, the said side walls extendingabove the front wall a distance as shown.

Shafts 3 3 are mounted at the upper and lower ends of the side walls as shown, and on these shafts are mounted two pairs of vertically aligned sprocket wheels as shown at 4 4 4 4:, the said pairs of sprockets being fitted with chains 5 5. This chain and sprocket mechanism may be driven in any suitable manner as by a pulley 6 mounted on the lower shaft 3 and driven by a belt 7 connected with a driving power not shown.

At spaced intervals on the chains 5 5 are mounted buckets or carriers 8, these carriers beingso proportioned as to extend substantially the width of the front wall 1 and to have their front edges in contact with the inner surface of the wall during the greater portion of their upward journey.

At the upper end of the front wall 1 and ou the inner surface thereof, are mounted two vertically extending elements 9 9,.eacl1' element having au inwardly and upwardly sloping cam surface 10 formed thereon, and a shoulder 11 formed therein to suddenly break the said cam surface. This shoulder is formed at the exact point where it is desired to effect the dumping of the several carriers.

Assuming now that the material to be elevated is fed into the lower end of the enclosure, each carrier 8 will take up a load as it circles the lowersprocket 1 and carry the load upwardly as indicated by the arrow. These carriers S are held substantially in contact with the wall 1 as they travel-up wardly past the idler 12, but when they reach the cam surfaces 10 they are forced away from the wall, bending the chain inwardly and tipping the carriers upwardly somewhat as shown in dotted lilies at 13. When the carrier reaches the shoulder 11 the tension on the chains 5 snaps it suddenly forward against the bumper 16 and into the position shown in dotted lines at 14, this action discharging the contents of the carrier over the upper edge of the front wall 1 onto the chute or whatevermay be provided for its reception. After discharging the carrier moves upwardly and over the tops of the elements 9 9 and around the sprockets again to receive another load.

By means of this construction the contents of each carrier is forcibly discharged therefrom without the necessity of providing any mechanism whatever for inverting the same. Each carrier is mounted upon the chains in the simplest manner without the provision of any pivotal or tripping mechanism, other than the means for engaging the edge of the carrier and causing it to lag behind the side mounted on the carrier chains and then releasing it to snap back into its normal position. In the present case the tension on the chain is sufficient to return the carriers to their normal positions, but of course other means may be provided.

It is to be understood, of course, that while I have herein shown and described but one specific embodiment of my invention, changes in form, construct-ion, and method of operation may be made within the scope of the appended claims.

I claim:

1. A structure of the character described, comprising a carrier element and means for rotating the same through a given path of travel, a plurality of spaced carriers open on their outer sides and mounted on said carrier element on their inner sides, and means for emptying said carriers at a given point in their path of travel, said means comprising a mea-ns for engaging the discharging side of the said carriers'whereby to cause the same to lag behind the opposite closed side,

and means for releasing the carriers from said engagement, and means for returning the carriers to their normal positions.

2. A structure of the character described, comprising an endless chain and means for rotating the same through a given path of travel., a plurality of spaced oarries mounted thereon on one side and extending outwardly therefrom and open on their outer sides, a wall positioned adjacent the carriers and means for urging the open sides of the carriers into Contact therewith7 and a dumping means Comprising a earn surface formed on the Wall in the path of travel of the car riers and having an abrupt termination.

`3. A structure of the character described,

comprising an endless chain and means for rotating the same through a given path of travel, a plurality of spaced carriers mounted thereon on one side and extending outwardly therefrom and open on their outer sides, a wall positioned adjacent the carriers and means for urging the open sides of the said carriers 'intoV Contact therewith, and a dumping means Comprising a cam surface formed on the Wall in the path of travel of the carriers and having-an abrupt termina tion, and a bumper positioned in the path of travel of the carriers and immediately succeeding the abrupt termination of the cam surface. i u i CHARLES F.
