SEEGIFLCATION forming part of Letters Patent No. 735,564, dated August 4, 1903.

Application filed April 2, 1902. Serial No. 101,101. (No model.)

To all whom, it may concern.-

Be it known that I, WILLIAM L. MCCABE,

a citizen of the United States, residing at Seattle, in the county of King and State of Wash-' ington, have invented certain new and useful Improvements in Portable Oonveyers; 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 the art to which it appertains to make and use the same.

This invention relates to improvements in portable conveyers, and the object in view is the production of a compactly-constructedconveyer provided with means for facilitat veyer-frame being indicated in dotted lines.-

Figs. 4. and 5- represent enlarged detail views of the supporting-spool with surrounding parts. Fig. 6 represents a View in top plan of the discharge-chute with its guiding-shield,

the conveyer being partially broken away.- Fig. 7 represents a view of the same in side elevation. Fig. 8 represents a fragmentary perspective View of the shield and surroundand to employ means for enabling the read y transportation of the entire structure. In order to attain these and other similarly dcsirable ends, I employ a suitable conveyerframework, as l, of well-known construction, having one end pivoted, as at 2; to any suitable platform, as 3, said platform preferably consisting of parallel angle-irons secured together by suitable'cross-pieces, the platform being formed-in two lengths, one of slightly less widththan the other, the narrower length being arranged to slide longitudinally within the Wider, whereby'a telescoping action of the parts may be produced. The telescoping sections are preferably held in position rela- I tive to each other by bolts or pins passed through a longitudinal slot in one angle-iron and secured to the contiguous iron.

The inner pivoted end of framework 1 supports platform 3, and the outer end of said platform is preferably supported by suitable rotatably-mounted casters, as 4, eachhaving a shackle, as 5, secured to its axle (5, said shackle being provided with an integral arm, as 7, carrying a turnbuckle, as 8, which turnbuckle is threaded onto a suitable rod 9. The rod 9'detachably engages the platform 3, as at 10, whereby the casters 4 will be held in a fixed position during transportation of the conveyer upon the casters, but may be turned to an angle to their normal plane when it is desired to move the conveyer laterally.

As best seen in Fig. 9, a collar, as 11, surrounds each side angle-iron of platform 3, each collar beingprovided with an eye, as 12, said eyes being connected by rods 13.13, threaded at their inner ends into a turnbuckle, as 1 1.

Mounted on the transverse horizontal braces of platform 3 is a motor, as 15, of any suitable and preferred type, carrying any desired driving means,-as a pulley 16, normally extending beyond one of the longitudinal angleirons of platform 3. The end of motor 15 opposite that carrying pulley 16 preferably lies in a vertical plane a sufficient distance inside its contiguous longitudinal angle-iron to permit of said pulley'l6 being brought inside the vertioal plane of its corresponding longitudinal angle-ir0n by a lateral adjustment of the motor. The motor 15 is also mounted to slide longitudinally of platform 3, and suitable winding-drums, as 17 and 18, are arranged at or near the ends of said platform and connected .by cables with said motor for adjusting the same to any desired position.

As best seen in Figs. 3 and 9, I preferably form an auxiliary laterally-projecting platform, as 19, integral with or connected to ICO platform 3 in any preferred manner, and my object is when desired to lift the motor bodily and place the same in operating posi tion upon the said platform 19. A second auxiliary platform, as 20, is supported upon a frame extending upwardly from and in the same vertical plane with framework 1 for receiving the motor 15, as indicated in dotted lines in Fig. 1, the supporting-beams of said frame being preferably connected to the sides of said framework 1 for permitting the articles conveyed to be passed thorebetween.

Mounted upon platform 3, near the castersupported end thereof, are two pair of standards, as 21 21, one pair 011 each side of the platform, the standards of each pair being spaced apart, the outer being braced by a bracket, as 22, and the inner hinged, as at 23, the upper ends of the respective standards being secured together by a strap, as at 24, to which is attached the upper end of a brace 25. The lower end of brace 25 is removably connected with platform Between said standards extends a shaft, as 26, carrying a spool 27 and having grooved pulleys, as 28 2S, fixed to its ends. The lower ends of the pairs of standards 21 are preferably braced in any suitable manner, as by transverse bars 29. A shaft, as 30, is arranged above platform 3 and carries a winding-drum, as 31, at each end thereof, suitable means, as a ratchetwheel 32, designed to be engaged by a pawl 33, carried by an operating-lever 34, being provided for rotating shaft 30 and its drums. Each pair of standards 21 carries brackets 35, in which are revolubly mounted the shaft of a grooved pulley, as 36. Each pair of standards 21 has a cable, as 37, fixed near the upper end thereof and extending downwardly about its respective pulley 28, passed upwardly about its respective pulley 36, and again passed downwardly and secured to its respective drum 31. It will now be apparent that rotation of drums 31 in one direction will tend to raise shaft 26 and spool 27, and rotation of said drums in an opposite direction will lower said parts, thecables 37 being of a sufficient length to permit shaft 26 and spool 27 to be lowered any desired distance. The framework 1 carries suitable drums, as 39 and 40, at the ends thereof for supporting a carrier-belt, as 41, the said belt in operation moving about drum 39 longitudinally of framework 1 and about drum 40. It next passes about a driving-drum, as 42, and is lapped upon itself in an opposite direction to that of its return movement, passes about a tension-drum 43, and then passing onward to and about drum 39, that part of the return of the belt between drum 43 and drum 39 lying approximate the upper portion of the belt, whereby the lower portion of framework 1 is left vacant for purposes hereinafter mentioned. The drum 43 may be provided with any suitable means for moving the same laterally longitudinally of the framework,whereby the amount of lap in the return portion of belt 41 may be increased or decreased for controlling the tension of the belt.

A shaft, as 44, extends transversely through framework 1, carrying a driving-pulley, as 45, at one end and a smaller pulley (not shown) at the other, the former pulley being driven by a belt 46, receiving motion from pulley 16, and the latter pulley imparting motion through a belt, as 47, to a pulley 48, fixed to a shaft 49,carrying drivin g-d rum 42. A lever, as 50, is pivoted, as at 51, to framework 1 and carries two idler-pulleys, as 52 and 53, spaced apart and designed to engage the respective portions of belt 46 for regulating the tension thereof. The lever 50 may be of the elbow type and, if preferred, may carry a suitable weight at its free end.

It willreadily appear from the drawings that theframework 1 rests upon spool 27 and that the open space in said framework left by the particular arrangement of the driving-belt is designed to register with motor 1.5 for inclos- 'ing the same when the framework is lowered sufficiently.

In operation it is often found desirable to permit the upper end of framework 1 to rest upon the ship to which articles are being conveyed, and in such instances a guiding-chute, as 54, is preferably connected to said end of the framework and usually arranged at right angles thereto. An arm, as 55, is pivoted to the upper end of the framework, and a second arm, as 56, is pivoted beneath the same, the former preferably normally extending in a horizontal plane and the latter being provided with a series of apertures, as 57, and extending in a diagonal plane across the former, the two being preferably secured together by a pin passed through a given aperture 57 and a suitable aperture in arm 55. The apertures 57 permit of vertical adjustment of arm 55. The upper end of chute 54 rests upon arm 55, and a slot, as 58, is formed longitudinally of said chute, near that edge thereof nearest the framework 1, and a pin, as 59, carried by said framework, extending through said slot for retaining the chute against lateral movement, but leaving the same free to swing up and down with the movement of the vessel upon which it rests. A standard, as 60, extends upwardly from chute 54 and is secured to a guiding-shield, as 61, for retaining said shield in position, the said shield consisting of a sheet of suitable material curved from the point at which it is attached to standard 60, which lies in line with one edge of belt 41, to a point on the opposite side of the chute lying in line with the opposite edge of said belt. A standard, as 62, is pivotally attached to arm 55 to swing transversely of said framework, but held against lateral movement in the longitudinal plane of said frame. The upper end of standard 62 engages shield 61 near the upper edge thereof by means of a bolt passed through a segmental slot, as 63, in said shield.

It will now be apparent that articles con- IIO veyed by belt 41 will be directed against shield 61, which will guide the same at a right angle to their former movement and down chute 54. Any vertical movement of said chute will be accommodated by pin 59, with its slot 58, and by the pivotal attachment of standard 62, the vertical movement of the upper end of framework 1 being taken up by said pin-and-slot connection and by the segmental slot 63.

Although I have specifically set forth one particular embodiment of the present improvements, yet I desire it understood that I shall not limit myself to the minor details of structure, but shall deviate therefrom to any degree within the spirit and scope of the present invention.
