CONVEYER.

Specification. of Letters Patent.

Patented Sept. 19, 1905.

' Application filed June 16,1905. semi No. 265,515.

To all whom it may concern: I

Be it known that I, LAWRENCE ABRAHAM, a citizen of the United States, and a resident of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Conveyers, of which the following is a specification.

My invention relates to conveyers for transmitting packages or merchandise from one floor of a building to another, and has for its object to improve and simplify conveyers of this description.

My invention'will be fully described hereinafter, and the features of novelty will be pointed out in the appended claims.

Reference is to be had to the accompanying drawings, in which- Figure 1 is a vertical section of my improved conveyer. Fig. 2 is a front view thereof, and Fig. 3 is a horizontal section on line 3 3 of Fig. 1.

The conveyer may be in the nature of an endless belt or chain having runs A and A. The said belt passes over pulleys B and C, said pulleys being mounted to turn on shafts B and C, supported in suitable bearings. (Not shown.) The entire conveyer is mounted to operate in an inclosure having walls Fand G. Upon the outer surface of the runs A and A of the belt are secured shelves H and H, which swing about pivots I. A member J extends downward from the pivot I of the shelves on the ascending run A of the belt, and a member J extends upwardly from said pivot I, it being understood that the member J extends upwardly about twice as far as the member J extends downwardly. In other words, the member J is about twice as long as the member J. It is to be further understood that the distance from the outer surface of the belt to the outer edge of the shelves H and H corresponds to the length of the member J. The shelves H and H and the members J and J may be made in one piece, as shown, or the parts may be separate pieces secured together, it being understood that 1 the shelves H and H are preferably made to dip toward the belt, so that the danger of packages falling from said shelves is minimized. The wall G of the inclosure may eX- tend from the top to the bottom of the conveyer and serves to prevent goods or packages from falling from the shelves and also to prevent accidents. The wall F terminates at a point near the top of the conveyer and has secured to it a chute K. The point where this wall stops must be determined by the length of the member J. In other words, the member J "must have sufficient room to swing past the point where the wall Fstops as the packages are discharged from the shelves H when the said shelves H H pass over the pulley Bfrom the ascending to the descending run of the belt. After the shelf H has become inactive on the descending run of the belt, owing to the fact that it has become inverted, goods may be placed on the shelf H to be transferred to a lower floor. It will thus be seen that my conveyer can be used both for raising and for lowering packages.

As the shelves pass over the roller B the member J serves as a steadying device by bearing on the surface of the belt to prevent the shelf from tilting too soon, and when the said shelf reaches the tilted or delivering position the member J acts as a short chute, which owing to its length projects beyond the wall F and over the edge of the chute K, thus preventing any of the packages from dropping into the space between the wall F and the descending run A of the belt. This is clearly shown in Fig. 1.

At its lower portion the wall F is curved to correspond to the path of the conveyer and ends in a curved chute L. Thus if packages are placed on one of the shelves H to be carried downwardly and the said shelf begins to pass over the pulley C the package will gradually slide nearer to the outer edge of the shelf as the said shelf becomes more and more tilted, assuming eventually the position shown at the lower part of Fig. 1. The curved portion of the wall F thus serves as a guide to prevent the packages from being suddenly thrown from the shelf, it being understood that the package is held by the outer edge of the shelf H and the wall F and gradually lowered as the belt continues to travel until the space between the outer edge of the shelf H and the wall F becomes greater than the widthof the package, whereupon said package is released and slides from the curved chute L to the point of delivery. This mode of delivery does away with any danger of packages or articles placed on said conveyer plies to the ascending delivery, the parts being so proportioned that the outer edge of the member J is close to the chute K before the article is delivered from the member J to the chute K.

Various modifications may be made without departing from the nature of my invention.

I claim as my invention 1. The combination of an endless conveyerwith pairs of converging shelves pivoted to said conveyer, and holding members of unequal length connected with each pair of shelves and extending in opposite directions from the pivot.

2. The combination of an endless conveyer with v airs of converging shelves pivoted to said conveyer, and holding members connected with each of said pair of shelves and extending in opposite directions from its pivot.

3. The combination of an endless conveyer having ascending and descending runs, with shelves pivoted to said conveyer, holding members connected with the shelves and projected in opposite directions from each pivot, stationary walls adjacent to the runs of said conveyer, and discharge-chutes located at the upper and lower ends of the wall which is adjacent to the descending conveyer run.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.

LAWRENCE ABRAHAM.
