SPECIFICATION forming part of Letters Patent NO. 341,486, dated May 11, 1886.
Application filed December 18, 1885. Serial No. 186,044. (No model.)
To aZZ whom it may concern.-
Be it known that I, FRANK W. KEYs,of the city of New York, in the county and State of New York, have invented an Improved Hod- Elevator, of which the following is a specification, reference being had to the accompanying drawings, in which Figure 1 represents a side elevation of my improved hodelevator. Fig. 2 is a side view, on a larger scale, of part of the hod. Fig. 3 is a detailed face View of the chain. Fig. 4 is an end view, partly in section, of the hod. Fig. 1 is a sectional side view of the upper part of the machine, showing it locked by the raised hod. Fig. 5 is a face view of the machine. Figs. 6, 7, and 8 are details hereinafter to be further referred to.
This invention relates to improvements in hod-elevators, and has for its object, first, to facilitate the placing of the hod upon the chain; second, to automatically arrest the motion of the machine when the hod is raised; third, to provide means for stretching the chain; and, finally, to supply the elevator with an alarm which will notify the engineer or operator below that the hod has been raised.
The invention consists of the sundry new features of improvement that are hereinafter more specifically explained.
In the accompanying drawings, the letter A represents the lower frame, and the letter B the upper frame, of the hod-elevator. These two frames are, when the machine is in use, placed on the lower and upper floors of a structure, respectively, and may therefore be varying distances apart; hence the chain 0, which connects the frames A B, will be of varying lengths, according to the variations in the distance between said frames.
In the lower frame, A, is hung the wheel D, and in the upper frame, B, a similar wheel, E, the endless chain 0 passing around both said wheels. The chain 0 is made up of series of links,which are united by detachable bolts or rungs; and when to shorten the distance the chain is to be shortened some of these links are taken out,while some are put in to lengthen the chain; but inasmuch as these links are of certain particular lengths the exact distance to be traversed by the chain may not always be obtained by the simple removal or insertion of links, the bearings of one of the wheels D E may have to be shifted to produce the exact adjustment desired and to hold the chain properly taut. shaft (1, which carries the wheel E, vertically adjustable. This shaft- I hang in two blocks, 1) I). which at d d are pivoted to vertical rods F F, such rods being notched or toothed along their outer edges, as shown in Fig. 8, to receive each in one of its notches the locking-pawl c, which is pivoted to the frame B. 'When this pawl lies flat on the top cross-bar, f, of the frame B, as in Fig. 5, it holds its vertical rod F in a certain fixed position; but by the lever G, which can be inserted against the toothed lower part of the rod F, through an aperture in the frame B, beneath the cross-barf, (see Figs. 5 and 8,) the rod Fcan belifted from the position shown in Fig. 5 into the higher position, as in Fig. 8, until the chain 0 is properly stretched, the pawl e dropping into the proper notch to lock said rod F in the desired position. In like manner by the lever G the rod F, although first lifted to disengage the pawl 0, can after ward be lowered, and the pawl set into the new notch for locking said rod F in a lower position. The leverG may be a mere loose rod, to be used only when the adjustment spoken of is required. Rotary motion is imparted to the lower wheel, D,by suitable gear-connection with the drivingshaft H, (see Fig. 5,) which driving-shaft may be turned by hand or by machinery, as may be desired. The chain 0 carrieaat equal intervals on L-shaped links 9 (see Fig. 2) horizontal inwardly-projecting pins 71, upon which the hod I is to be supported. This hodI has on its converging sides metal plates i with inverted- U-sl1aped ribs j thereon. These ribs, of which there is one on each plate i, form suspension-hooks for holding the hod on the chain. This is clearly represented in Figs. 2 and 4, in both of which figures the pins h are shown by dotted lines in engagement with the concave upper parts of the bent ribs j. The hod having this To this end I have made the g arrangement of ribs at its sides can be readily placed upon the nearest set of pins 71, and as readily taken therefrom, and this employment of the ribsj has been found a more convenient means of adjustment for such hods than any heretofore devised. The hod I has the usual downwardly-extending shank or stick, Z, which connects, in this instance by a brace; m, with the lower parts of the metal plates 3, which are attached to the converging sides of the hod. Fig. lshows the connection between said brace m and said plates M to be established by a pin or bolt, a.
I will now describe the means for automatically arresting the motion of the chain when the hod has been elevated to the proper extent. The shaft a carries the ratchet-wheel 0, which revolves with the shaft in the direction of the arrow shown near it in Fig. l. The pawl 11 is out of engagement with said ratchetwheel when the hod is being raised. This pawl connects by a cord, q, with a pivoted platform, J, which is jointed to the frame B, and which lies in the path of the hod I, as in Fig. 1. \Vhen the hod reaches the under side of this platform, it lifts it, as in Fig. 1, and thereby draws the cord qand pulls the pawl 19 into en-' gagement with the ratchetwheel 0, thus arresting the rotation of the shaft (1. and the motion of the chain 0 and the hod I. A'branch, q, of the cord q extends downwardly and connects with a cord, 8, that is wound around a drum, t, which is hung in the frame B. Another cord, at, which is also wound upon the drum t, carries at its lower end the notched plate awhich is adjustably secured to a lever,w, which connects with the clapper w of a gong, L. When the platform J is swung up, as in Fig. l, to arrest the motion of the chain, the cord q and cord 8 are pulled up,so as to revolve the drum t and pull on the cord at and sound the gong, thus notifying the attendant at the lower station that the hod has been elevated to the proper extent,and that the machine is,or is to be,arrested. The adjustability of the notched plate 1; in. the clapper-lever w is for the purpose of holding the cord to and its connections on top properly taut. One tooth of the notched plate '0 is by a suitable spring, 00, crowded against the locking-edge of the clapper.
It remains to show how the cords q and s are connected and separated at their proper time. Figs. 6 and 7 show this arrangement. The lower end of the cord q carries a hook, a", which has a pin, If, that guides it in a straight slot of a sheathing, a", that is attached to the frame B. The upper end of the cord 8 carries a similar hook, d". The two hooks a and d" overlap one another, as in Fig. 6. When, therefore, the cord q is drawn up, it
draws the cord 8 by the hook connection up with it and sounds the gong; but when the hook d has been raised sufficiently its beveled upper end comes in contact with the beveled lower end of an abutment, e, which is adj ustably secured in the sheathing 1', as in Fig. 6, and is by such contact crowded laterally off the hook a". This is shown by dotted lines in Fig. 6. The hooks being now disengaged, the clapper-lever w, under the influence of a suitable spring or weight, is permitted to swing down again, and to draw the cords to s and hook d down again into the position which is shown by full lines in Fig. 6.
The drum t is for the purpose of supplying sufficient lengths of cords s or a, or both, to suit any distance the frames A and B may be from one another.
I claim- 1. The combination of the separate frames A and B, the chain-wheel D on the frame A, and endless chain 0, with the wheel E, shaft a, blocks I), upright notched rods F F, and pawl c, all arranged substantially as described and shown. 4
2. The combination of the frame B,'having appropriate aperture,with the notched rod F, lever G, pawl e, and block b, and with the shaft a hung in said block, as specified.
