WILLIAM LOUDEN, OF FAIRFIELD, IOWA.

HAY-CARRIER.

SPECIFICATION forming part of Letters Patent No. 752,569, dated February 16, 1904.

Application filed December 14, 1903. Serial No. 185.049. (N model.)

To all whom it may concern:

Be it known that I, WILLIAM LOUDEN, residing at Fairfield, in the county of J eiferson and State of Iowa, have invented a new and useful Improvement in Hay-Carriers, of which the following is a specification.

This invention relates principally to an improvement in the lock mechanism of hay-carriers; and it consists of means whereby the IQ elevating-pulley will be caught and held between grappling devices below the hub of the pulley Wheel while the carrier is running along the track and will be free to swing therein; also, of means for causing the grappling r 5 devices to act in unison, and of other features herein described, and set forth in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a hay-carrier embodying my invention. Fig. 2 is a horizontal section looking downward on line 2 2 of Fig. l, the elevating-pulley and rope not being shown. Fig. 3 is a transverse section on line 3 3 of Fig. 1. Fig. 4 is the same, the carrier being moved along the track, so that line 3 3 will co- 2 5 incide with line 4 4. Fig. 5 is a transverse section of a modified form of grappling devices and elevating-pulley with the lockingdog broken off, the balance of the carrier not being shown. Fig. 6 is a side elevation of a modified form of pulley-frame to be used with the modified form of grappling device.

In the drawings, A is an overhead track. B is the upper frame of a hay-carrier, and C the track-wheels mounted in said frame. D is the 3 5 lower frame of the carrier, swiveled to the upper frame and carrying sheaves or rope-wheels E. F is the elevatin -pulley, and Gr the hoisting-rope, which is passed through it and over the rope-wh eels E, all 'in the usual manner.

The sheave H, with which the pulley F is provided, is fitted with a hub H and with a narrow web I. The frame of the pulley F has outwardly-extending portions J, which are adapted to fit over the ends of said hub. The 45 portions of the pulley-frame immediately surrounding the ends of the hub are inwardly contracted, so as to give more prominence to the extended portions J.

Two grappling devices K are pivoted in the 5 lower frame of the carrier at X, so as to stand parallel with the sides of the frame and to oscillate at right angles thereto. The upper ends K of the grapples K are adapted to coact with a locking-dog L, while their lower ends'are provided with loops M, which are adapted to catch under the extended portions J on the pulley-frame F.

The grappling devices K are provided with inwardly-projecting fingers N, which overlap each other and are passed into a sleeve on the end of an intermediate piece 0. This piece is forked at the other end and is provided with bosses P, which are pivoted in the sides of the carrier-frame. The locking-dog L is provided with an annular base and upwardlyprojecting arms fitted at their upper ends with inwardly-projecting lugs Q. It has a vertical movement in the upper frame of the carrier, and the upper lugs Q are adapted to slide up the inclines of the track-stop R and the lower ones to catch against the shoulders S thereon, all of which is fully explained in my Patent No. 634,949 and is therefore known to the art.

The sides of the lower frame of the carrier are provided with a pair of vertically-spaced bars T, having pivots X therein. The central portions of the grappling devices are preferably made open and the edges spread apart. On each of the edges a lug V is formed, which is adapted to enter the opening between the bars T, and is fitted so as to receive and oscillate upon the pivots X. The bars T and the parts of the frame below them are outwardly extended, so as to afford room for the free movement of the grappling devices K therein. 8 5 The upper ends of the grappling devices are preferably contracted, so as. to form a central head K. I

The carrier being moved along the track so the'lines 3 3 will coincide with the lines 4 4 of 9 Fig. 1 will assume the position shown in crosssection in Fig. 4. The elevating-pulley F, being drawn up by the rope G, will come in contact with and raise the free end of the intermediate piece 0. This will raise the fingers N and cause the grappling devices to turn in unison on their pivots, so the locking-dog L will drop between the heads K, and the lower lugs Q, will be freed from the stop R, so the carrier can run along the track A. At the same in I00 'st'ant (in fact just before it) the loops M will catch below the projections J and will hold the pulley F with its load suspended while the carrier is running along the track. Return- 5 ing to the stop R again, the upper lugs Q will slide up the inclines of the stop and the locking dog L will be lifted from between the heads K, and the grapples K will turn on their pivots X, so as to assume the position shown in Fig. 4, and thus release the pulley F. The heads K, turning inward under the bottom of the dog L, will hold it in contact with the stop R, and thus the carrier will be held stationary on the track A.

The advantages of the construction herein shown are many. The lower ends of the grappling devices form guides for the pulley F, so as to bring it into its proper position, thus dispensing with the use of flaring bell-mouths of the carrier-frame generally used for this purpose. The pulley F is caught and securely held between the grappling devices K at a'lower and more central point, thus permitting it to approach the carrier at a considerably inclined angle and to swing freely to the left or right while held by the grapples, as shown by the dotted lines U. The intermediate piece 0 forms a central point of contact for the pulley F and causes the grapples K to turn freely. The grapples being pivoted at two points between the vertically-spaced bars T will be firmly held against any longitudinal strain, and the whole will make an easy sure-working carrier.

It is evident that a number of changes can be made in the details of construction without departing from the spirit of my invention.

Although it is preferable to pivot one end of the intermediate piece 0 to the carrierframe, this may be dispensed with by constructing the fingers N with shoulders, as shown by Fig. 5, and instead of overlapping them, as shown in Figs. 2, 3, and 4, to make them meet in the center and fill the entire opening in the intermediate piece 0. In this way it will be held in place and the forked ends may be cut off. It is preferable, however, to pivot the intermediate piece at one end, and I have constructed the carrier-frame with pivot-holes at each end, so that it may be pivoted at either end desired. Also instead of making the frame of the pulley F with the.

central projecting portions J they may be made with an opening W under the hub of the pulley-wheel, as shown by the pulley and frame for same, F, in Figs. 5 and 6, and the lower ends of the grapples may be made with inwardly-projecting shoulders Y to enter these recesses and support the pulley.

Any suitable form of locking-dog with a -track-stop to coact therewith may be used in place of that shown, and, if desired, the frame of the carrier may be made of one integral part instead of being made with upper and 5 lower sections swiveled together. Also other assess changes which do not affect the operation of the grappling devices K and the intermediate piece 0, with the pulley F, may be made without departing from the spirit of my invention.
