ELEVATOR FOR BAGS, 80C.
SPECIFICATION forming part of Letters Patent No. 294,015, dated February 26, 1884.
Application filed October 24, 1883. (No model.)
To all whom it may concern.-
Be it known that I, ADAM CONRAD, of Ohicago, in the county of Cook and State of Illinois, have invented certain Improvements in 5 Elevators for Bags, of which the following is a specification.
The nature and object of my invention will be hereinafter described with reference to the accompanying drawings, in which-- Figure 1 represents a front elevation of an elevator embracing my improvement in its construction; Fig. 2, a vertical cross-section of the same, taken as indicated by the broken line :0 x in Fig. 1; Fig. 3, a perspective of the I 5 endless elevator-belt B, with the carrying devices in position on the same; Fig. 4, a horizontal section of the same, made as indicated by the broken line 1 y in Fig. 1; Fig. 5, a vertical cross section, made as indicated by the broken line 00 w in Fig. 1; Fig. 6, a detail view of the automatic devices for dumping or unloading packages; Fig.7, a detail view of the carrying devices, designed to illustrate their position when in the act of passing around 2 5 the belt-pulleyCor the pulleybelow; and Fig. 8, a like view, on an enlarged scale,of the skids c and their bearings.
A indicates the two uprights or supports, which are fastened to the topmost floor above 0 and the lowermost one below; H, the drivingpulley, to which the power is applied through its shaft H, which'is itself connected to the engine through the universal coupling H; J, a cross-frame, upon which are bolted the bearings of the shaft H, and the frame pivots or rocks upon shaft J; O, a rack-bar fastened on the frame J; O, a pawl pivoted to one of the upright supports A; G, a large beltpulley mounted upon shaft D; and I, its belt,
4o encircling it and the pulley H, adapted and designed to convey power from the shaft H to shaft D; F, a brake-pulley mounted upon shaft D and operated by the two brake-shoes F, one on each side, and both pivoted to proper bearings in the frame. The'brakeshoes are held normally engaged with pulley F by the weight N on cord N, attached to the vertical lever F on pivot F, connected by two links, as shown, to the brake'shoes F. The cord M, running over guide-sheave M, connected with lever F is used by hand to disengage the brake shoes F when required.
The weight J tilts the frame J when the pawl O is raised from the teeth of the rack-bar O by hand by means of the cord L running over .pulley a on the lever L, which is hinged to the floor above and pivoted to thevertical rod is, and rests with its foot upon the frame J. The application of the power to shaft D is made by depressing the frame J, and thus tightening the belt I upon pulley H by means of force applied by the hand to cord L, attached to the outer end of lever L, which forces frame J downward by means of the vertical rod 70. The pulley H, its frame J, shaft H, belt I, and pulley G are designed merely to throw the elevator out of connection with the power when required and the brake to hold the elevator when so disconnected.
D is a pinion on shaft D, and meshes with the large cog-wheel E,which is mounted upon shaft O,which itself carries the belt-pulley G, and this last-named pulley and the like one below (not shown in the drawings) are traveled over by the endless belt B, upon which are bolted a series of carriers, (shown in Figs.
3 and 7,) which consist of the bed-plate a, made preferably of metal, to which is fastened a wooden frame, a, and to this frame the two arms a, rigidly fastened together at right angles to each other, arehinged, as shown in the drawings at a These carriers, in pairs, are fastened to the belt 13, with suitable intervals between the pairs around the belt, so that when it is set in motion around its pulleys the 8 5 carriers may carry up and deliver bags and packages upon one side of the uprights A, and carry down and deliver others upon the other side at the same time, and the deliveries may be made upon anyfloor of the building or warehouse in which the elevator is employed.
The result of the mechanism shown and described is that when the'belt B travels in the direction indicated by the arrows in Fig. 7, a pair of the carriers having ascended upon the belt and passed beyond the center of pulley C, will tilt upon their hinges and appear as shown in Fig. 7 and upon their descent the bar a, which was below in the ascent, will be above.
In order to secure true action on the part of belt B and prevent its buckling or yielding in any direction under the weight of packages, the two uprights A may be cut away in front from the inner edgessay two-thirds of the distance across to their outer edgesor their front faces maybe left plain, and bars B about one-third as wide as an upright, A, may be fastened against the outer side of the face of each upright, and then to these bars B may be securely fastened the plates B,which should be a few inches wider than bars B, so that recesses for the edges of the belt I, behind the plates 13 and in front of the upright A will be formed so that the belt cannot yield edgewise or from the front to rear. The recesses or ways so formed serve also to guide and stay the reversible carriers, for the bedplates a of the carriers are made much wider than their frames a, and their outer edges project into the described recesses or ways about as far as the edges of the belt do, and any strain caused by the weights upon the carriers against the belt will be sustained by the uprights A, immediately behind it. Thus the plate guides and confines both the belt and the carriers.
The unloading or dumping device shown in Fig. 6 consists of the bars I) and o, rigidly attached to each other, and the bar a is pivoted at b and confined in bracket 1). Now, as the package resting 011 the bars a is carried up, it passes the lower end of barb, and is forced outwardly by it until bar 22 attains nearly a horizontal position, when it is forced off the carriers altogether. The bar 1; is provided with a hinge, so that it can be folded back upon the stop b, out of the way, when required. This device, in pairs, is for use when bags and packages are to be carried upward, as from one floor to another above it; and whenever they are thrown off, they are caught and conveyed away from the belt and onto the floor by devices which I have invented for that purpose. These devices are preferably made of round rods of iron, and bent into the peculiar form shown in the drawings. These skids a rest with their lower ends 011 the floor, and their upper ends in sockets or brackets in or upon uprights A. They are bent widely asunder near their upper ends, and form loops 0*,
in order to allow a long bag or package to pass up between them; and then, after sufficient loops have been'formed, they are again bent toward each other, and then extended in par allel directions, as shown, in order that when the bag falls upon them, as it will do, some distance from the belt, its ends, respectively, may project so far beyond the skids as not to be liable to bend downward and fall between them.
In order to catch and remove out of the way and onto the floor bags and packages descending from an upper to a lower floor, I have provided the skids c, in pairs. Their feet may have sockets in the floor, and their upper ends sockets in or brackets upon the uprights A, and their upper ends are just outside the carriers; and the latter, as they pass down, leave the bags or packages upon them to slide or roll down upon the floor.
I will here add a few words of explanation of the parts and their operation, described in the first part of this specification. Vhen the pawl is engaged with the rack-bar, the tiltingframe J is held down against the weight J and the belt I is held taut upon the pulley H, and the power is transmitted to the elevator through the shaft D, pinion D, and cog-wheel F and shaft 0; but when the power is to be taken off, the pawl is disengaged by means of force upon cord L when the weight J will raise pulley H, which will then revolve free of the belt I.
WVhat I claim as my invention, and desire to secure by Letters Patent, is-
1. The endless belt 13, provided with the tilting reversible carrier composed of the frame a and the two arms a, rigidly connected together and pivoted or hinged to the frame, substantially as and for the purpose described.
2. The described dumping device, composed of the bar I) and of the bar 0, rigidly attached thereto, and pivoted at Z), adapted to throw off packages in their upward passage, substantially as described.
3. The described dumping device, consisting of bar I) and bar a, rigidly fastened thereto and pivoted at b, and provided with a' hinge, as shown inFig. 6, adapting it to be folded back out of the way when packages are to be elevated above it, substantially as described.
'4. The skids c, bent laterally, as shown, so as to form loops 0 in each one, and leave space for a bag to pass up between them, and made detachable and interchangeable for use on any floor in the building, the lower ends resting on or in the floor, and their upper ends loosely in sockets or brackets, adapted to allow' packages to pass up between them and then catch them when thrown off the carriers and guide them to the floor, .substantially as described.
5. The rods 0' in pairs, having bearings for their upper ends in the uprights A, and for their lower ends in or upon the floor, and detachable, adapted to receive bags or packages in their downward passage and guide them out of the way and upon the floor, substantially as described.
