C. E. MCCARTNEY HOISTING SKIP Filed Sept. 26, 1925 lighter construction Patentel Apr. 2%, i925,
CHARLES E.'IEGCARTNEY,: 015 BED BLUFF, CALIFQRNIA.
I-IOISTING SKIP,
Application filed T 0 all whom it iii/cry concern.
Be it known that T, Canteens E. Mc- Can 2112*; citizen of the United States.
residing at lied Bluff, in the county of Tehama and State of California, have in vented certain new and useful improvements in Hoisting Skips, of which the following is a specification.
This invention relates to a hoisting skip and more particularly to a hoisting skip adapted for use on small work where the use of heavier buckets and larger hoists would be lRIPIHCi lCZLl. The skip of the present invention is designed to receive the mixed concrete from a concrete mixer and discharge it into achute or into wheel-barrows on scafi'olds at any desired ele ation. The dumping of the bucket may be eliected automatically at a fixed point or this dumping may be brought about at any desired elevation by operation of a hand trip. The bucket is of sufficient capacity and is low enough when at its lowest point to receive the output of the small split-sack llllXCl'S commonly used on small jobs. Since a much than ordinary is sufficient to hold the hoisting bucket of this invention, a correspondingly less powerful hoist is required.
Further objects and advantages of the invention will be set forth in the detailed description which follows.
In the accompanying drawing:
Fig. 1 is a plan view of the skip the guide timbers shown in section;
Fig. 2 is a front elevation of the and associated parts;
Fig. 3 is a side elevation of the skip alone; and
Fig. at is a side elevation of the tipped to dun'iping position.
Like reference characters designate cor responding parts throughout the several ligures of the drawing.
In the construction of the present invention G designate guide timbers which serve to guide the skip frame consisting of the vertical channel irons S, a lower horizontal connecting channel iron S connected to the channel iron S by riveted plates S and a pair of upper spaced channel irons T which are secured at their ends to the channel iron S by angle irons T. The spacing of the channel irons T from each other provides a space within which a grooved pulley P is journaled and the hoisting cable H passes wi th sk i p sk i p septeniber 26, 1923.
Serial No. 664,841.
over this pulley. The bucket B is mounted for tipping movement in the frame by a trunnion rod F which is secured to the channel irons S. The trunnion rod F passes through angle irons R which are riveted to the sides of the bucket. A cross angle iron A of a relatively small size is secured to the upper ends of the channel irons R and its ends project a suliicient distance beyond the channel irons R to abut against the channel irons S and thus limit the rearward movement of the bucket B. The bucket is held in an upright position when loaded by latches a which are carried by a latch yoke/L of rectangular formation, said yoke being pivoted at Z) to the channels S. /Vith the latch yoke in the position il lustrated in 3 the latch es a engage the upper ends of the channel irons It and hold the bucket B in upright position, but if the latch yoke be swung to the full line position illustrated in Fi g. i then the bucket may tilt under the influence of gravity to the position illustrated in said Fig. d, it being understood that the center of gravity is in front of the pivot constituted by the trunnion rod F. The movement of the latch yoke L may be effected manually at any desired point in the upward movement of the skip but in addition it may be effected by disposing a stop bracket J in the path of movement of said yoke, said bracket J being-carried by the timbers G. The stop yoke may be disposed at any desired height upon the timbers G and whenever the. latch I yoke reaches that point and its rear portion engages said stop yoke its forward portion will be tipped upwardly as illustrated in Fig. l and the bucket B will be permitted to swing forward and discharge its load. Upon downward movement of the skip the bucket is restored to its former position automatically when dumping into chute, or by an attendant when dumping into Wheelbarrow. This automatic return of the bucket when dumping into a chute is effected by the end I) of the bucket engaging the inner end of chute as the skip starts downwardly and this, in turn, tips the bucket back to its upright position.
Downward swinging movement of the latch yoke to the dotted line position illustrated in Fig. l is limited by an angle iron M which spans the distance between and is secured to the channel irons S.
It is to be understood that the invention is not limited to the precise construction set forth but that it includes Within its purview Whatever changes .fairly come Within either the terms or the spirit of the ap pended claim.
Having described my invention What .I claim is:
In a structure of the character described the combination with side frame members constituting a vertical track, of a rectangular open hoisting frame slidably mounted thereon, a bucket having an inclined front Wall and having its center of gravity so disposed as to cause it to tip forwardly when released, a pair of vertical bars secured to the sides of said bucket, said bars and bucket being trunnioned in the rectangular frame, a transverse element extending between said bars above the bucket, a rectangular yoke secured to and carried by the hoisting frame and comprising side members pivoted to said hoisting frame and transverse members extending across said hoisting frame, latches carried by the said side members and adapted to engage the transverse member that extends between said bars and a stop member extending between the frame members of the vertical track and adapted to engage said yoke and rock the same to release the transverse elementfrom said latches.
In testimony whereof I ai'fix my signature.
CHARLES E. MQCARTNEY.
