Specification of Letters Patent.

Application led July 10, 1916. Serial No. 108,466.

CLEAVER, residing at 21 Bossuet street, in the p city of Montreal, Province of Quebec, Do

minion of Canada, and THOMAS HENRY MARTIN, residing at 201 Montgomery street in the city of Montreal, in the Province o Quebec, in the Dominion of Canada, have inventedy certain new and useful Improvements in a Conveyer; and we do hereby declare that the following is a full, clear, and exact description of same.

The invention relates to improvements in conveyers and consists in the combination and varrangements of parts as herein .set forth and claimed, whereby the conveyer is telescopic and may be extended to any suitable length. Means are provided to operate the said conveyer.

The objects of the invention are to provide a simple device, cheap of construction, durable and easy to operate. Another object is to provide a conveyer that may be portable.

With reference to the drawing, Figure 1 represents a side elevation of the invention in its non-extended position.

Fig. 2 represents a side elevation of the invention in its extended position.

Fig. 3 is a plan view.

Fig. 4 is an end view looking from the front of the conveyer.

Fig. 5 is a cross section on the line A-A. of Fig. 1.

Like numerals of reference indicate corresponding parts in each ligure.

In the drawings, 1 and 2 are 4parallel tubes supported at one end by the frame 3 and at the other end by the standards 4, 5 is a hopper suitably supported above the said tubes 1 and 2 by means of thebrackets 6. 7 is a roller suitably journaled between said tubes 1 and 2 at their rear ends.

8 and 9 are parallel rods telescoping in the said tubes 1 and 2; and 10 are standards or legs, secured to vthe outer end of said rods 8 and 9, and adapted to support same.

11 and 12 are rails suitably secured to said frame 3 and standards 4, below said tubes 1 and 2 and parallel thereto; and 13 is a frame adapted to slide on said rails 11 and 12, and secured at one end to the rods 8 and 9 by means of the brackets 14.

15 is a roller suitably rear end of said .frame 13.

16 is another roller suitably journaled in the outer or forward part of the rods 8 and 9.

17 -is a roller suitably journaled within the frame 3 and actuated by the motor 18.

19 are rollers provided at intervals, and mounted on the said tubes 1 and 2 and rods journaled at the 8 and 9; and 2O are obliquely disposed rollers mounted on said tubes 1 and 2 and rods 8 and 9, and so adapted as to dish or curve upward the sides of the conveyer belt 21.

AThe endless belt 21 passes over the rollers 7, 2O and 16 and back over the roller 15. From the roller 15 it passes over the roller 17 and back to the roller 7.

The frame 13, being secured to the rods 8 and9, will be carried forward when the rods 8 and 9 are pulled out from the tubes 1 and 2 if it is necessary to extend the conveyer, thus carrying with it the roller 15. The roller 15, being carried forward with the frame 13 and the rods 8 and 9.and the roller 16, will eliminate any slack in the belt, as the distance that will be increased between the rollers 16 and 7 will be taken up by the roller 15.

The objects of this invention are to provide a simple device for the transmission of coal or such like substances and to be capable of .being lengthened or shortened as desired without .stopping the machinery between two pre-determined points. It may also be equally well used either as a portable or a stationary appliance.

An important point is that in extending or in closing the conveyer the tension on the belt will not be interfered with.

This conveyer has been designed for loading coal over ship-board, but it will be found helpful anywhere that a conveyer is required to carry material between two points.

An adjustable scraper 22 is placed against the belt on the roller 16 in order to keep thev details of the herein described invention can be modified if it is desirable, so long as We do not depart from the invention ask claimed in the following claim for novelty.

What We claim is A conveyer comprising parallel tubes suitably supported by standards and provided with a roller journaled thereon, parallel rods telescoping in said tubes suitably supported by standards and provided with a roller suitably journaled thereon, sliding rails secured to said standardsbelow said tubes, a frame adapted to slide on said rails provided at one end with a roller suitably journaled thereon and secured at the other'end to said rods, a roller suitably journaled below said frame, an endless belt passing over said rollers, means totake up the slack'in the said belt, a transverse rod suitably secured to saidframe adjacent to the outer per mounted at the end of said tubes above said'endless belt, and a motor actuating said rollers substantially as described.

Signed at Montreal, Quebec, Canada, this 21st day of June, 1916.
