HOIST OR ELEVATOR.
Specification of Letters Patent.
Patented Jan. 2, 1906.
Application filed April 6, 1905. Serial No. 254,105.
To aZZ whom, it may concern.-
Be it known that I, CLAUs A. JUHL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hoists or Elevators, of which the following is a full, clear, and exact specification.
My present invention is designed as an improvement upon the invention shown and described in my United States Letters Patent No. 768,902, granted to me August 3 0, 1904; and it has for one of its objects to reduce the width of the machine in a direction lengthwise of the barrow or plane of rotation of the main belt-wheels whereby the device will be appropriate for use in buildings where the joists or floor-beams are in place and comparatively close together and the cost of the belts and main belt-wheels will be greatly reduced and less unwieldly, a further object being to have the construction such that the barrows will descend on the same side of the machine at which they are placed in position for elevating. With a view to accomplishing these objects I have provided certain improvements in the construction, combination, and arrangement of the parts, which will now be describedavith reference to the accompanying drawings, and more particularly pointed out in the claims.
In the said drawings, Figure 1 is a rear elevation of my improved machine. Fig. 2 is a plan section on the line 2 2, Fig. 1. Fig. 3 is a vertical section on the line 3 3, Fig. 1; and Fig. 4is avertical section on the line 4 4, Fig. 1.
In Fig. 3 is shown a loaded barrow 1 in the act of ascending, and in Fig. 4 is shown an empty barrow 2 in the act of descending. The sides of the barrows are provided with yokes 3, the same as in my aforesaid patent, and with which yokes engage lugs or pins 4 on chains or belts for raising and lowering the barrow. In my present invention I employ two sets of these chains or belts, one set for raising the barrows and the other set for lowering them, whereas in my aforesaid patent the barrows were raised and lowered by the same pair or set of belts. In my present invention the belts or chains 5 are used exclusively for raising the loaded barrows, while the pair of belts or chains 6 are employed exclusively for lowering the empty barrows. The belts 5 engage with sprocket-wheels 7 8, mounted at their lower ends upon a drivingshaft 9 and by which the belts are caused to travel. The upper ends of the belts run over sprocket-wheels 10, mounted upon shafts 11 12, respectively, at a distance apart, so as to leave room-between them for the passage of the barrow when ascending. The barrow rises through an opening 13 in each floor 14 and passes up around the wheels 10 with the lugs or pins 4 and comes down on the other side above the floor 14 and finally settles upon an incline, preferably composed of two arts 15 16, the part 16 being in the form of a 'nged trap, which normally remains in the position shown in Fig. 3 or in its lowered position; but when the wheel of the ascending barrow strikes it it rises to allow the barrow to pass upwardly and then falls again by gravity into its former position in time to catch the barrow as the barrow descends. When the barrow lights upon the incline 15 16, the lugs or pins 4 pass downwardly out of engagement with the yokes 3, and the barrow being thus released gravitates down the incline out of the way. The hinged section 16 may be provided with a counterweight 17, so as to prevent the section from slamming, and the inner end of this section may be supported at the sides by standards 18.
The loaded barrow may be attached to or placed upon the ascending belts 5 at the bottom in any suitable way. I have shown for this purpose a skid or incline 19, which leads upwardly to a cushioned platform 20, em-
ployed in my former invention for support-v ing the barrow preparatory to the engagement of the lugs 4 with yokes 3, whereby the chains will be relieved of sudden strain.
The shaft 11 is supported in suitable standards 21 and the shaft 12 in similar standards. 22. The standards 22 may also serve for the support of a second shaft 23, upon which is mounted one of the sprockets 24 25, which support the upper ends of the belts 6, the other sprocket 25 being supported on a shaft 26 in standards 27. The lower ends of the belts 6 pass around sprocket-wheels 28 29, mounted upon a shaft 30, which is separate from the shaft 9, but is connected thereto by means of gear-wheels 31 32, so that the two shafts 9 and 30 rotate in unison, the shaft 9 being provided with a suitable driving-pulley 33.
The emptybarrows to belowered are rolled upon a hinged support or trap 34, arranged at the edge of the opening 13 in the floor 14 and provided with a counterweight 35, so that when the barrow is removed the trap will assume a vertical position, as shown in Fig. 4,
and allow the handles of the barrow to pass downwardly. When the barrow is thus placed upon the trap 34, the ascending sides of the belts 6 will be in line with the yokes 3, and consequently the lugs on the ascending sides of the belts 6 will automatically engage with the yokes 3 and lift the barrow upwardly from the trap 34, carrying it up around and between the sprockets 24 25 and thence downwardly on the other side, where it finally lights upon an incline or skid 36, while the lugs or pins 4 pass downwardly out of engagement with the yokes 3 and allow the empty barrow to run down the incline out of the way of the next one, this incline'36 being arranged on the same side of the machine as the incline 19.
As shown in Fig. 3, the centers of the sprockets for the two sets of belts are not concentric; but this is incidental to the presence of the gear-wheels 31 32, which are employed for causing one set of belts to travel in the reverse direction of the other set, and thus bring the barrows down on the same side on which they ascend.
Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-
1. In an elevator or hoist the combination of two sets of vertically arranged endless belts, one or more receptacles for the material to be hoisted, means on said belts and receptacles whereby the receptacles are supported upon the belts, means for supporting the receptacles between the belts preparatory to the hoisting thereof by the belts, and means for driving the belts in opposite directions.
2'. In an elevator or hoist the combination of two sets of vertically-driven belts, a receptacle for the material to be hoisted, means on the belts and receptacle whereby the belts engage and lift the receptacle, means at the lower end of one set of said belts for supporting a receptacle to be elevated between the belts, means at the upper end of the same set of belts for catching the elevated receptacle, arranged between the belts, means atithe upper end of the other set of belts for holding the receptacle to be lowered, between the latter set of belts, and means at the lower end of the second set of belts for catching the lowered receptacle.
3. In an elevator or hoist the combination of two pairs of vertically driven belts, one or more receptacles for the material to be elevated, means on said receptacles and belts whereby the receptacles are engaged and raised by the belts, means between the belts of one pair at the lower end for supporting a receptacle to be elevated, means between the belts of the same pair at the upper end, but on the opposite side for catching the elevated receptacle while coming downwardly means between the belts of the second pair at the upper end for holding a receptacle to be lowered, means between the belts of the second pair at the lower ends but on the opposite side for catching the lowered receptacle and means for driving said belts.
4. In an elevator or hoist the combination of two pairs of upright belts, a receptacle for the material to be elevated, means on said belts and receptacles whereby the receptacle is engaged and elevated by the belts, means between the belts of one pair at the lower end for su porting a receptacle to be elevated, a hinges incline projecting between the same pair of belts at the upper end in the line of movement of the receptacle while on that pair of belts, for catching the elevated receptacle, a normally elevated, hinged support between the belts of the second pair at the upper end for supporting a receptacle to be lowered, and means between the belts of the second pair at the lower end for catching the lowered receptacle.
