DAVID E. HUGHES, OF SAN DIEGO, CALIFORNIA.
CONVEYER.
SPECIFICATION forming part of Letters Patent No. -v'774,476, dated November 8, 1904. Application filed March 30, 1904. Serial No. 200,786. (No model.)
To a/ZZ whom, t may concern.-
Beit known that I, DAVID E. HUGHES, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented new and useful Improvements in Conveyers, of which the following is a specification.
rI`he object of my invention is to receive, transfer, and deliver material from one place to another without canting it. I accomplish this object by means of the mechanism described, and shown in the accompanying drawings, in which- Figure l is a perspective view of my apparatus, partly broken away and illustrated as applied to a conveyer for handling cylindrical bodies. Fig. 2 is a diagrammatic view of an elevation thereof. Fig. 3 is an elevation of the ratchet-wheel. Fig. 4 is a view of the worm-gear, partly broken away, and the friction device on the shaft carrying the worm,
partly broken away for clearness of illustration. Fig. 5 is a modification of the friction device shown in Fig. et. Figs. 6 and 7 are plan and edge views, respectively, of the upper table, showing the frame Q and ating-lever R.
In the drawings, A represents a frame which supports the shaft B, upon which are keyed the chain-operating wheels O. Mounted upon and operated by these wheels are the endless chains D. vWorlably secured thereto are a plurality of bent hanging beams E, (only one of these beams being shown in the drawings, because to show more would confuse the same.) These beams are journaled at each end in the chains and the beams have a downward offset to lower the center of gravity below the axis of suspension. To the horizontal depressed portion of the hanging beams E are secured'the load-supporting cross-arms F. These cross-arms in number and form are adapted to receive the material to be transferred from the lower table and at the same time are sufficiently elevated above the beams to leave clearance between the beams and the load, so as to permit the load to pass over and the beams under the the operprojecting ends of the slats M of the upper table, which receive the material from the cross-arms as they pass down for a new load. The tables shown in the drawingsare specially designed for use in raising and lowering cylindrical bodies.
H represents the lower table, upon which the material to be elevated is placed. This table is composed of a series of slats H. Between the ends of these slats the projecting ends yof the cross-arms F pass in elevating whatever material rests upon the table H. On each side of the table I have provided a guide K to prevent any oscillation of the hanging beams E.
The upper table L, of any suitable form and construction, is provided with ovcrhanging stationary members M,wh ich in number, form, and position permit the hanging beams E to passthereunder and the cross-arms F to pass between and leave theloads on the members -of the table.
By a reverse movement and changing the pitch of the two tables loads may be taken from the upper table and deposited upon the lower table. At the outer end of the upper table are placed the double-acting detents N, having a movement in the mortises O. These detents are rigidly mounted on and operated by moving the common cross-rod P, which passes through the detents. A longitudinal movement of the frame Q, which carries the rod P, will operate the detents, and this frame is operated by the operating-lever R. This lever on being pushed one way will move the detents N within their mortises O, depressing the outer ends o'f the detents to permit the outermost load to leave the table and projecting the inner ends upwardly to prevent the next load from following. Thenareverse movement of the lever will permit the next load to roll to the position at the end of the table vacated by the first load.
Pivoted in the lower table and between the slots thereof are a plurality of detents S, adapted to permit the cylindrical loads to pass over them. The front ends are depressed by the load, and the rear ends are elevated and prevent thereby the following cylindrical loads from approaching too near the load on the front of the detent, thereby aifording arnple room for the projecting ends of the crossarms F to pass up between the load about to be raised and the adjacent load on the table.
The mechanism is driven by hand or other power through the worm-gearing T, (shown in detail in Fig. 4,) which insures smooth and noiseless movement and perfect safety against runaways whether in raising, lowering, or holding the loads. The eiiiciency of the wormgearing is greatly increased by employing a steep pitch for its thread and a ball or roller thrust-bearing U, Fig. 4, while its safety against racing is retained by the device shown in Figs. 3 and 4, which consists of pawl V and ratchet W, with sleeve X attached, between which and the worm-shaft are a number of loose annular disks Y, alternate ones, Y/, of which are by their shape constructed and arranged to revolve with the shaft, while the rest are adapted to turn or stand with the sleeve and ratchet-wheel. In raising loads all turn together, with the worm against the thrust-bearing U. In holding and lowering loads pawl V prevents retrograde motion of sleeve X and alternate disks Y, while the other disks, Y', each under the pressure of the thrust of the worm-gear T, revolve with the worm and supply the necessary additional friction required to make the steep-pitched worm safe. With this device all contained in a bath of oil within the housing of the worm-gear a high efiiciency is attained without sacriiice of safety.
In case the conveyer is operated by a motor having surplus power and connected there- Vwith other than by belt, then for safety a clutch-coupling shown in Fig. 5) is introduced between the motor and the worm-shaft, which coupling has keyed to shaft l a sleeve 2, eX- tending over another shaft, 3, said sleeve containing a number' of annular disks 4 and 4', alternate ones, 4, of which are constrained to stand or turn with the sleeve 2, and the others stand or turn with the shaft 3, the necessary pressure between the disks being supplied by the adjustable spring 5, held by collar 6.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is
l. In a conveyer of the character herein described having means to feed cylindrical objects one by one from the lower table to the carrying cross-arms; cross-arms rigidly mounted on the cross supporting-beam, the cross-arms being mounted on and above the cross-beam, the said cross-arms being spaced apart to permit of their passage between the projecting ends M of the upper table and the supporting cross-beam to pass below the ends, in combination with the upper table having projecting members M positioned thereon to permit the cross-arms to pass between said projecting members of the upper table and deposit their load on the upper table.
2. Means to elevate objects without canting them, from a lower to an upper table of the character herein shown and described comprising a frame having journaled therein an upper and a lower shaft; chain-carrying wheels keyed thereon two endless chains carried by said wheels, cross supporting-beams journaled in said chains and having downwardly-projecting odsets; load carrying cross arms mounted above and on the supporting crossbeams; the cross-arms spaced apart and above the beams sufficiently far to pass above and on either side of the projecting ends of the upper table, and the supporting-beams below the projecting ends.
3.

4. In a conveyer of the character herein described, an upper and a lower table, the upper table being made up of a plurality of stationary members spaced apart and having upwardly-projecting ends adapted to receive the load from the load-carrying cross-arms when the conveyer is in operation, the lower table being made up of a plurality of stationary members adapted to deliver the load therefrom onto the load-carrying cross-arms; endless chains extending from the lower to the upper table, means to operate said chains; a plurality of supporting cross-beams journaled in the endless chains and having downwardlyprojecting osets; load-carrying cross-arms mounted on the supporting cross-beams, the projecting ends of the cross-arms adapted to IOO pass between the projecting ends of the tables In witness that I claim the foregoing I have and remove the load from the lower table and hereunto subscribed my name this 19th day of TO deposit the sarne on the upper table, the said March, 1904. cross-arms being' spaced apart to straddle the 5 projecting ends of the tables and havingtheir upper surfaces disposed above the top of the Witnesses: supporting cross-beams and below the level HENRY T. HAVARD, of the eross-beam-supporting pivots. Gr. E. HARPHAM.
