AUGUST H. DAHL AND ARTHUR E. WHITELY, OF NEW YORK, N. Y.,

ASSIGNORS OF ON E-TENTH TO CHARLES 0. DAIIL, OF NEW YORK,

CONVEYER.

Patented June 11, 1907.

Application filed May 2,1906. Serial No. 314,877.

To all whom it may concern:

Be it known that we, AUeUsr H. DAHL and ARTHUR E. WHITELY, citizens of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Conveyers; and we 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 conveyers, and

hasfor an object to provide a conveyer adapted for use in connection with building and structural operations and for hoisting and conveying building and structural material to and about a building in course of construction.

A further object of the invention is to provide a conveyer of the class described embodying a track arranged to embrace and encircle the building under construction and a carriage arranged to move about said track and about said building and embodying a derrick carried upon said carriage.

A furtherobject of the invention is to provide a carriage for operation upon a track of the class described, provided with a derrickmast erected thereupon, and means for retating the derrick upon'its mast or the mast upon the carriage, and with means for moving the said derrick about the track, and for operating the derrick portion of the carriage.

A further object of the invention is to provide a track arranged in sections for interchangeable connection to permit of expansion and contraction of the track for use on buildings of different sizes and provided with means for supporting said track at the necessary height relative to said building.

With this and other objects in view, the invention comprises certain novel, constructions combinations and arrangements, as will be hereinafter fully described and claimed.

In the drawings: Figure 1 is a view of the improved conveyer in side elevation. Fig.2 is a top plan view of the improved conveyer.

. Fig. 3 is a vertical, sectional view of the improved conveyer, taken on the line 3-3 of Fig. 2. Fig. 4 is a perspective view of the carriage and derrick associated therewith. Fig. 5 is a detail view of the track construction.

Like characters of reference designate corresponding parts throughout the several views.

In its preferred construction, the device forming the subject matter of this application comprises a track designated as a whole at and comprising an I-beam 11 having an upper double flange 12 and lower flange l3, wider than the upper flange. The track 10 is composed of sections interchangeable and adjustable with joints as shown at 14, the said sections being held in operative relation by means of plates, as 15, bolted to the inside of the lower flange 13, as by the bolts 16. The sections'are provided with overlapping tongues 17 formed in the web of the I-beam and with the flange sections overlapping as at 18 to permit of their being engaged by the bolts 16. The track is supported in any suitable manner, as by being rigidly attached to the structural frame of the building upon which it is being used, or is provided with independent means of support, as the struts 19, preferably formed of sheet metal curved lon itudinally, as shown particularly in Fig. 2, i or the purpose of rendering the said struts the more rigid. The struts are braced in any suitable manner against lateral displacement, as by the braces 20, and the track is supported thereupon in any approved manner, as by forming slots 21 in the curved face of said struts and providing the track portion with brackets 22 positioned to embrace the said struts on opposite sides and connected by means of the bolt or pin 23, proportioned for engagement within the slots 21.

Upon the track formed of the I-beams 11 is mounted a carriage shown as a whole at 24, and comprising a body portion provided at opposite ends with cross-heads 25 curved downwardly, affording at their opposite ends ears 26, to which are journaled rollers 27 positioned to bear and operate upon the lower flange 13 of the Lbeams. Within the downwardly curved portion of the cross heads 25 are formed bearing members 28 to which are journaled vertical rolls 29 positioned to bear against the web of the I-beam 11 and prevent lateral displacement of the carriage.

Upon the carriage 24 is mounted a tubular upright 30 within which is rotatably mounted a mast 31 having at its lower end a ratchet wheel 31 engaged by a pawl 32 pivotally mounted upon a carriage 24 and by which the mast 31 is held against rotary displacement.

The mast 31 is provided at its upper end with a boom 33 with its opposite ends extending upon opposite sides of the mast andprovided with pulleys 34 and 35 and with cable guides 36 and 37. Upon the upright 30 is provided an arm 38 rigidly extending therefrom and having a pulley 39 rotatably mounted in its bifurcated extremity.

Extending about and above track 10 is a sprocket chain 40 carried at each corner of t e said track by idlers 41 and operated by means of a sprocket 42 preferably mounted at one corner of the track and rotated by means of a shaft 43 extending downwardly through the said track and provided at'its lower end with a gear 44 engaging a similar gear 45 upon the shaft 46 which is operated by a sprocket 47 over which is passed a sprocket chain 48 engaging at its opposite end a sprocket 49 rotated from any convenient source of power, as the conventional engine 50. Extending about and above the track is also a cable 51 carried at the corners upon idlers 52 and having one of its ends extending through the pulley 39, then upwardly over the pulley 35 and downwardly over the ulley 34 and engaging any load, as a buc ret 53. After passing about the track structure over the idlers 52 as noted,

the opposite end of the cable passes over a pulley 54 journaled upon a bracket 55 rigidly carried by the track 10. The cable 51 passes downward as at 56 and about a drum 57 which is mounted upon the shaft 58 by means of any improved clutch mechanism.

Upon the mast 31 is mounted a slidable plate 59 provided With a slot 60 engaged upon a pin 61 held normally at the upward extremity of its movement by means of a spring 62. The upper end of the plate 59 is pivotally secured to a lever 63 which is pivoted at its opposite end, as to pin 64, and provided with a curved finger 65 ositioned to engage the upper surface 0 the boom 33 when the plate 59 is drawn down- I wardly against the tension of the s ring 62.

In its operation, the carriage is he din any approved operative position by means of the sprocket chain 40, and the bucket or other load, as shown at 53, raised or lowered as may be required. When the load has been raised to operat ve position the carriage 24 and its associated mast and load are moved about the track in the direction of the arrow, the said load being held at the required height by reason of the drum 57 being of the same diameter as the sprocket 49 and the intermediate gearing being so proportioned that the cable 51 moves at the same rate as the sprocket chain 40. When the load 53 has reached its desired position, the boom 33 may be rotated as required by disengaging the pawl 32 and thereby releasing the ratchet 31. When the load has been released from the cable 51 the said carriage is returned by a reverse movement of the drum and sprocket and another load raised and moved in like manner.
