ANDREW L. ANDERSON, MONTEVIDEO, MINNESOTA.

CARRIER.

To all whom it may concern:

Be it known that I, ANDREW L. ANDERSON, a citizen of the United States, residing at Montevideo, in the county of Chippewa, 5 State of Minnesota, have invented certain new and useful Improvements in Carriers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in use the same.

This invention relates to carriers and particularly to that type for travel upon an elevated cable or track.

The invention has for its object to construct a device of this character with simple and eflicient tripping means, whereby the contents may be discharged automatically.

A further object of the invention is to construct a tripping mechanism for devices of this character wherein the contents of the receptacle is discharged automatically and upon slightly reversing the travel of the same. I

In the drawings :-Figure 1 is a side elevation of the carrier. Fig. 2 is an end view. Fig. 3 is a sectional view on line 3-3 of Fig. 1, the receptacle being spread. Fig. 4: is a detailed view of the tripping mecha- 30 nism. Fig. 5 is a similar view showing the same in the act of tripping.

Referring to the drawings, the numeral 1 is a cable, said cable being suspended in any suitable manner.

The device proper consists of a supporting frame 2 having depending arms 3, said arms being held in their spaced relation by a bar 4. The upper ends of the arms 3 are bent over to form hangers 5. Rotatably mounted in the hangers 5 are grooved wheels 6 bars 8.

The receptacle consists of two parts, each part having a side 9 and bottom 10 and ends 11, and are pivotally connected at their op posite ends to the transverse bars 8, whereby when said sections are in their position for carrying refuse or the like one of the bottoms 10 overlaps the corresponding bottom of the opposite section, thereby forming a receptacle.

Secured to one ofthe grooved wheels 6, and to the side thereof is a semicircular cam Specification of Letters Patent.

12, said cam being tapered throughout its length to produce a beveled outer face 13 and a blunt end 14. The cam 12 may be riveted to the wheels 6, or the same ma be molded to form an integral part thereof.

Pivotally mounted upon one of the arms 3 is a bell crank lever 15, said lever being provided at its upper end with a cam plate 16, said plate having its outer face formed with a bevel 17, which contacts with the beveled outer face of the cam 12 when the wheel 6 revolves. The cam plate 16 is held yieldingly in contact with the side of the wheel 6 and the beveled face 13 of the cam 12, during their rotation by a coil spring 18 which encircles a pivot bolt 19, it being of course understood that the bolt 19 is threaded in a suit-able opening formed in the arm 3, and may have head rotatably mounted to regulate the tension of the spring 18. A link 20 has its upper end pivotally connected to the lower end of the bell crank lever 15, said link being provided at its lower end with a boss 21 and to which are connected the inner ends of bars 22, each of said bars being provided with shoulders 23 so that when the same contact both bars assume a horizontal position, whereby a rule joint is produced. Pivotally connected to the outer ends of the bars 22 are links 24, said links being arranged cross-wise, so that their lower ends may be pivotally connected to the ends 11 of each section forming the receptacle.

When the cam 12 rocks the bell crank lever 15 the link 20 is moved vertically until the bars 22 are removed from their hori: zontal relation, thereby causing the sections forming the receptacle to spread as clearly shown in Fig. 3 of the drawings, to discharge the contents.

The operation of the device is as follows: When the receptacle is traveling in the directions of the arrow the cam 12 due to its peculiar formation passes the cam plate 16, this being readily accomplished as the bell crank 15 is allowed to move laterally and against the tension of the spring 18. This operation continues, the parts remaining in position as shown in Fig. 1 of the drawings, and in no way interfering with the rotation of the wheel 6 upon which the cam 12 is carried. After the receptacle has traveled to a position where .it is desired to discharge the contents, the travel of the carrier is then reversed, which causes the wheels 6 to Patented July 2, 1912. t

revolve in an opposite direction and until the blunt end 14 of the caml2 engages the cam plate 16, and upon further movement in this direction the bell crank 15 is rocked until the sections of the carrier are spread a sufiicient distance apart to allow all contents therein to be discharged. It will be of course understood that the cam plate 16 does not contact at all times with the beveled face 13 of the cam 12, but is held in yielding contact with the uninterrupted side surface of the wheel 6, that is when the receptacle is traveling in the direction as indicated by the arrow in Fig. 1. When the direction of travel is reversed, the cam and wheel 6 rotate until the blunt end 14 of the cam engages the rear end of the plate 16, whereby the lever 15 is rocked and the sections of the receptacle spread for discharging the contents. The receptacle is caused to travel back and forth upon the cable 1 by ropes (not shown), and said ropes may be operated in any suitable and well known manner.

The carrier is particularly adapted for use in barns or the like wherein it is desired to remove refuse therefrom and deposit the same at a distance from the barn and in a pile for ready removal.

lVhat is claimed, is

1. In a carrier, in combination, a frame, wheels for supporting the frame, a sectional receptacle carried by the frame, a cam carried by one of said wheels, a bell crank lever pivotally connected to the frame, said cam acting to rock the bell crank lever to spread the receptacle, upon travel of said frame and receptacle in one direction only.

2. In a carrier, a cable, a frame, wheels for supporting the frame upon the cable, a sectional receptacle supported by the frame, a semicircular cam formed upon one of said wheels and having a beveled outer face, a bellcrank lever pivotally connected to the the cable, a sectional receptacle supported by the frame, a bell crank lever pivotally connected to said frame, a semi-circular cam carried by one of the supporting wheels and having a beveled outer face, a cam plate carried upon the upper end of the vertical arm of said lever, the semi-circular cam being adapted to engage the cam plate to rock the bell crank lever upon travel in one direction only, whereby the receptacle is spread to discharge its contents.

1-. In a carrier, in combination, a cable,

4 a frame, wheels for supporting the frame on the cable, said frame having depending arms, a transverse bar secured to the lower end of each arm, a sectional receptacle having its sections pivotally supported by said bars, a cam carried by one of the wheels, a bell crank lever pivotally secured to one of said arms, a link pivot-ally connected to said lever, a pair of bars pivotally connect-ed at their inner ends to said link, a pair of links having their inner ends pivotally connected to said bars and their outer ends pivotally connected to one end of each section of the receptacle, whereby when said cam rocks the bell crank lever the sections of said receptacle are caused to spread to discharge the contents.

In testimony whereof, I affix my signature, in presence of two witnesses.
