CARRIER-TRACK.

To all whom it may concern:

Be it known that we, WILLIAM MITCHELL and JOHN F. MITCHELL, citizens of the United States, residing in Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Carrier-Tracks, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specificationQ This invention relates to improvements in carrier tracks which are particularly adapted to support carriers which are used in removing manure or other material from large barns or stables to the outside of the barn whereby the carrier may be discharged at any point desired within certain limits.

A further object of the invention is to provide a carrier track in the form of a crane or boom which is pivotally connected to a barn or other permanent support and which is adapted to be swung outwardly therefrom at any angle desired.

A further object of the invention is to provide a carrier track of the character described which is provided with a flexible portion toform a curved bend which will permit the travel therearound of the carriers in passing from the track within the barn to the pivotal track connected thereto.

A further object of the invention is to form a carrier track of the character de scribed which is so formed, braced and supportedthat a light and very rigid structure is provided. With the above and other objects in view, the invention consists of the carrier track and its-parts and combinations as set forth the same reference characters indicate the same parts in all of the views: Figure 1 is a side view of the track shown connected to the side wall of a barn, the barn wall being shown in section; Fig. 2 is a plan view of the track; Fig. 3 is a transverse sectional view-on a larger scale of the track taken on line 3--3 of Fig. 1. Fig. 4 is a detail View of the supporting rod.

Referring to the drawings the numeral 8 indicates a fragment of the wall of a barn or other buiding and 9 the doorway thereof. A hinge member 10 securely bolted to the door frame of the barn is provided with rounded projectionsll extending in vertical Specification of Letters Patent.

alinement with relation to each other and which are straddled by the fingers 12 extendlng in pairs rearwardly from the tube holding member 13. A supporting tube 14:,

the inner end of which is held in the socket of the tube holding member, extends therefrom horizontally the distance desired and the outer end and the medial portions are supported by stay rods or cables 15 and 16 respectively. These stay rods or cables are pivotally connected at their upper ends to an eye bolt 17 fastened to the upper portion of the barn and extend downwardly and outwardly at an angle and at their lower ends are connected to collars 18 and 19 respectively which surround the tube. When the supporting tube is formed of two or more pieces, the ends are coupled together by a split coupling 20 the half sections of which are bolted together to clamp the tube ends therebetw'een.

The collar 19 is provided with side socketed arms 21 carrying side tubes 22 which have notched caps 23 on their outer ends to accommodate truss brace rods 24. These rods are positioned on each side of the tube and are connected at their inner ends to the tube holding member and at their outer ends are hooked over the end of the tube, the outer ends of the rods being bent to form hooks 25 for that purpose. Turn buckles 26 form part of the length of the truss brace rods to provide for tightening said rods to form a rigid structure.

A track 27 consisting of angle iron portions 28 spaced a slight distance apart and connected together by cross ties 29 is suspended from the supporting tube by suspension rods 30. These rods which have eyes 31 formed on their upper ends through which the tube extends depend downwardly therefrom and have hook's 32 formed on their lower ends which hook beneath the cross ties 29 between the angle iron sections. The inner end of the crane track adjacent to the pivotal connection of the supporting tube to the hinge member is connected to a fixed track leading to the interior of the barn by short rail sections 33 which form a flexible track section to permit the swinging of said track horizontally in the arc of a circle. These rail sections are pivotally connected together and are also pivotally connected to a straight spring member 3 1 to normally hold the track sections in aline-J ment. A set screw threaded through the tube holding member securely fastens the tube to'said member.

- From the foregoing description it will be seen that the track is strong and durable and the construction permits the swinging of the crane to the right or left and the carrier may travel from the track within the barn to the crane track regardless of the position to which the crane has been swung.

What we claim as our invention is:

1. ,A carrier track comprising a hinge member, a supporting member pivotally connected to the hinge member and extending outwardly therefrom, supporting means connected to the supporting member and extending upwardly at an angle to a point above the hinge member, stay means bracing the supporting member laterally, suspension means depending from the supporting member, and a track connected to the suspension means and extending in a line substantially parallel with the supporting member.

2. A carrier track, comprising a fixed track, a hinge member positioned above the track, a supporting member pivotally connected to the hinge member and extending outwardly therefrom, stay rods connected to the supporting member and extending up wardly at an angle to a point above the hinge member, suspension means depending from the supporting member, a track connected to the suspension means and extending in a line substantially parallel with the supporting member, and a flexible track section interposed between and connected to the inner end of the suspension track and the outer end of the fixed track.

3. A carrier track, comprising a fixed track, a hinge member positioned above the outer end of the track, a tube holding member pivotally connected to the hinge member, a tube connected to and extending outwardly from the tube holding member,--stay .rods connected to the tube and extending upwardly at an angle to a point above the hinge member, stay rods bracing the tube laterally, suspension means depending from the tube, a track connected to the suspension means and extending in a line substantially parallel with the tube, and a flexible track section interposed between and connected to the inner end of the suspension track and the outer end of the fixed track.

4. A carrier track, comprising a fixed track, a hinge member positioned above the outer end of the track and provided with rounded projections extending in vertical alinement with relation to each other, a tube holding member having fingers which straddle the rounded projections, a tube connected to and extending outwardly from the tube holding member, a collar mounted on the tube and having arms extending horizontally at right angles to the tube, stay rods connected to the tube holding member and to the outer end of the tube and in engagement with the outer ends of the arms, stay rods connectedto the tube and extending upwardly at an angle to a point above the hinge member, rods. extending around the .tube and depending therefrom and vhaving
