\VILLIAM JOHN OBYRNE, OF CATOOSA, INDIAN TERRITORY.

ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 695,334, dated March 11, 1902.

Application filed November 15, 1901. Serial No. 82,381. (No model.)

To all whom it may concern:

Be it known that I,WILLIAM JOHN OBYRNE, a citizen of the United States, and a resident of Catoosa, Cherokee Nation, Indian Territory, have invented a new and Improved Elevator, of which the following is a full, clear, and exact description.

This invention relates to an elevator of that class in which buckets are employed on a traveling belt or chain; and the object of the invention is to so construct the buckets that it will be impossible for particles of stone or other material to fall between the buckets and the belt. This falling of material has heretofore been a serious disadvantage, resulting in clogging and stoppage of the elevator and in the tearing of the belt to which the buckets are fastened.

This specification isia specific description of one form of the invention, while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side view showing a section of the elevator in use. Fig. 2 is a sectional elevation on an enlarged scale, and Fig. 3 is a section on the line 3 3 of Fig. 2.

a indicates the belt, which is preferably formed of flexible material, such as a compo-' sition of canvas and rubber. The buckets b are fastened to the belt in the usual manner, and to the side of the bucket which lies against the belt is hinged an apron 0. These aprons are one for each bucket, the apron for one bucket bearing between the bottom part or foot of the adjacent bucket and the belt, as shown in Figs. 1 and 2. Each apron c is provided at each side with a wing (1, these wings lying against the sides of the buckets and serving to close the spaces between the aprons and the edges of the buckets, notwithstanding that the aprons may move on the buckets. For example, in Fig. 2 the upper apron is shown engaged with the bucket, the belt a being in a straight line. When the belt turns around a pulley, the apron will move away from the bucket, but the wings d of the apron will still engage the sides of the bucket and prevent the occurrence of an opening between the two parts.

Now by reference to Figs. 1 and 2 it may be seen clearly that the aprons 0 cover the spaces between the buckets, notwithstanding the positions which the latter may assume, and that owing to this arrangement of the aprons and wings thereon it is impossible for any material to fall between the buckets and the belt.

Various changes in the form, proportions, and minor details of my invention may be resorted to without departing from the spirit and scope of the invention. Hence I consider myself entitled to all such variations as may lie within the scope of my claims.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent- 1. An elevator-bucket, having an apron hinged thereto and projecting therefrom to prevent the material from falling between it and the adjacent bucket.

2. The combination of a carrier-belt, a plurality of buckets fastened thereto, and aprons hingedly mounted on the buckets, the aprons extending into engagement with the adjacent buckets, for the purpose specified.

3. An elevator-bucket, having an apron hinged to the open end thereof, and a wing attached to the apron and slidably engaged with the side of the bucket, for the purpose specified.

4. The combination of an elevator belt, buckets fastened thereto, and aprons hingedly mounted at the open ends of the buckets and extending into engagement with the adjacent buckets, said aprons having wings at the side edges and slidably engaged with the side walls of the buckets.

5. The combination of an elevator belt, buckets fastened thereto, and wings hingedly mounted at the open ends of the buckets and respectively extending to the adjacent buckets, said aprons projecting between the buckets and the belt to prevent material from entering into the space between these parts.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM JOHN OBYRNE.
