PORTABLE CRANE.

1HE MORRIS PETERS CO PHoro-LITHO.. WASHINGIUM D C,
here.,
PORTABLE CRANE.
To all whom t may concern Be 1t known that I, MILTON S. HAsnL'roN,
a subject of the King of Great Britain, re`
siding' at Beebe, in theProvince of Quebec and Dominion of Canada, have invented new and useful improvements 1n Portable Cranes, of which the following is a speci-` iication.
The invention relates to a portable crane, comprehending a structure in which the various parts are arranged for rigid interco-nnection when in operation, and adapted for convenient collapsing or folding `when not required for use.
The main object of the present invention is the provision of a portable crane including a truss support adapted to carry a traveler of the trolley type and `end members for the truss support with the whole connected for collapse in comparatively small compass when not required for use.
The invention in the preferred form of dctails will be described in the following specification, reference being had particularly to the accompanying drawings, in which Figure 1 is a view in side elevation, illustrating the improvement. Fig. 2 is an end elevation of the same. Fig. 3 is an enlarged detail, illustrating the connection between the truss support and the end rod. Fig. 4 is an enlarged broken sectional view illustrating the connection between the sections of the truss member and the upright.
In carrying out the improvement, I `provide a portable crane so constructed that it is capable of bearing extremely heavy loads as compared with the crane itself- The truss member 1 is made up of pipe sections 2 arranged in spaced longitudinal arrangement and connected by transverse brace sections 3 also the piping. Steel wire sections 4 are interlaced with the main section 2, and brace sections 3 so as to maintain a rigid connection2 and at the same time distribute the straln longitudinally of the truss rather than directly upon the main pipe sections. A trolley support 5 is mounted in hangers 6 depending from the lower main rod 2 and on this is adapted for `movement the ordinary or preferred type of trolley carrier 7 the lower end of which is preferably provided with a drum 8 from which the hoisting cable 9 is operated in any usual or preferred manner. The truss member `is supported by up- Specication of Letters Patent.

Serial No. 797,847. i
rights at the respective ends, each upright including a channel iron section 10 reinforced by filling of wood or the like 11, and a point adjacent the connection of the truss member with the upright. The truss I connected at the respective ends of the upper and lower main rods with the section 12 of channel iron of the size to slidably engage within the upper portion of the upright 10. flhe upper rod 2 extends through an opening 1n the inner channel iron section 12, a shoulder 13 on the terminal of the pipe preventing separation. *The wire `brace membersflf leading to the terminal of the upper main rod 2 are passed through said main rod at this juncture with the inner channel member 1 2, one of the wire cable braces being secured to the terminal of the rod section within the channel member 12, the other eX- tending beyond the terminal of the pipe and passing through a slot 1li in the upper end of the upright 10, a collar 15 securing the terminal` of this extended wire brace and bearing against the outer surface of the upright member 10. The lower rod member 2 extends through the inner channel member 'l2 and through the outer member, a pin 16 passing through the projected end of the lower member to secure the members against separation. By this construction the truss member and uprights are rigidly connected to insure a positive bracing action when the parts are arranged for use, while at the same time permitting their ready separation.
Movably secured to the lower end of each upright 10 is a. transverse supporting bar 17. Cables 18 and 19 connect the ends of the supporting bar with the upright, and one of said cables as 19 is connected to the lever Q0 adapted when turned in the upright position to tension said cable and when moved into lowered position to slacken the cable to permit its disconnection. By this means the cable connection with the upright may be loosened to permit the upright and supporting bar to be turned into parallel relation when it is desired to collapse the structure.
The use of the structure will be readily apparent from the above description, taken in connection with the accompanying drawings, it being obvious from the drawings that the improvement provides a portable member proper` 1s collapsible crane of comparatively light weight, and possessing a maximum -supporting quality.
What is claimed is l. A portable crane including a truss member, a channel member carried by the endsvof the truss member, a channel upright for supporting the ends of the truss member, said, channel member slidably fitting Within the upper ends of the channel upright.
2. A portable crane including a truss member, a plurality of,V Wire cables bracing said member, a channel member carriednby the ends of the truss member, an upright member of channel material into which the channel member isitted, one of the cables passing through the upright, and means cari ried by the cable to secure same beyond the upright.
3. A portable crane comprising a truss member, including Lipper and lower rods,- cable braces interlacing said rods, a channel upright for each end of the truss member,
a channel member carried by the respective bars of the truss member and fitting Within the channel upright, means bearing against the upright and receiving one of said cable braces to secure the same, the lovver rod ofthe truss member passing through the channel upright, and means for securing said latter rod beyond the upright.
