GEORGE E. BLOOD, OF N'UNDA, NEW YORK, ASSIGNOR TO FOUTE COMPANY, OF NUNDA, NEW YORK, A CORPORATION OF NEW YORK.

LOADING SKIP FOR CONCRETE PAVERS.

Application filed November 19, 1923.

To @ZZ whom t may concern:

Be it known that I, GEORGE E. BLOOD, a citizen of the United States of America, residing at Nunda, in the county of Livingston and State of New York, have invented certain new and useful Improvements in Loading Skips for Concrete Pavers, of which the following is a specification.

My invention relates to new and useful improvements in loading skips for concrete pavers, and particularly to the manner in which the skip is mounted on the paver.

One of the principal objects of the invention is to provide a loading skip having a double pivoted action, permitting the bottom of the skip to swing in a short arc thereby causing the materials to start flowing from the skip much more quickly than they ordinarily do when the skip has but a single pivot point and is elevated in a long arc.

Still another object of the invention is to provide a skip which is rigidly supported at two points, one point of support being near the mouth, and the other near the center of the skip bottom; these two points of support extending transversely of the bottom of the skip, thereby rigidly holding the skip in its path of movement and preventing the usual side sway.

Still another object of the invention' is to provide a skip and a means for mounting the same, so that the mouth of the skip passes over the top edges of the hopper by the time the skip back reaches a horizontal position, thereby eliminating all chance for any of the material to spill outside the hopper' Still another object of the invention is to so mount a skip that it will be elevated through a short arc, so that the lift is more nearly to the perpendicular, thus avoiding semi No. 675,611.

to provide a skip having two sets of supporting arms of different lengths and eccentrically mounted so that an initial lifting movement of the skip will draw the mouth of the skip inwardly towards the hopper of the paver.

Still another object of the invention is to provide a skip wherein the supporting arms may be quickly and readily secured to the skip and quickly mounted on the paver and after having been operatively secured, will need no further attention; and at the same time, will always prevent any side sway or lost motion during its travel.

Still another object of the invention is to provide a skip which will be economical in its construction and operation, and relai tively cheap to manufact-ure.

With these and numerous other objects in view, the invention consists in certain new and novel arrangements and combinations of parts, as will be hereinafter more fully described and pointed out in the claims.

Referring now to the drawings,

Fig. l is a perspective showing the skip and the manner in which it is mounted to the paver, the skipbeing shown in its lowermost position.

F ig. 2 is a similar View showing the skip, in this instance, in its uppermost or dumpl ing position.

Fig. 3 is a reduced diagrammatic view of the skip showing the arcs of travel in dotted lines, the skip being in its lowermost position.

Fig. 4 is a similar View, the skip being shown as partly elevated, and

Fig. 5 is a similar view, the skip being shown in its uppermost or dumping position.

Referring now to the several figures, there is shown one type of a Foote paver con sisting of a platform l, the endless track 2, the usual drum 3, a skip t, the cable 5 for raising the skip, and the support 6 for the cable. rllhe hopper 7 is also shown for the drum, as well as numerous other parts, but I have not shown any of the discharging apparatus of the paver, such as the boom, bucket, or the trough, etc.

Referring now more particularly to the skip a, it will be seen that it consists of a relatively short back 8, the side walls 9, and

lilf) the bottom 10, the side walls of both the back and the bottom merging and riveted along the lines shown. A cover 11 is shown above themouth of the skip extending rear-l wardly so that the materials in the skip will not overflow the side walls near the mouth. lt will he seen that the bottom of the skip extends at an obtuse angle to the back, and the greatest depth of the side walls is diagonally opposite the merger of the back and the bottom. A reinforcing angle iron 12 extends across the back and side walls to add'rigidity to the whole, while a suitable central b race 13 is shown to which the cable 5 is. attached; this cable passing over the Sheave liat the top of the support G and means, of course, are present to actuate the cable and raise and lower the skip.

Referring now more particularly to Fig. there will be seen a short bar or plate 15 which isl located transversely of the bottom of the skip and at a point near the center thereof. At the opposite ends of this plate 15 are two bearings 16 forthe pivotal. reception. of the long supporting arms 17 which are likewise pivoted at their lower ends of the rod 18, which in turn, is suitably mounted in the bearings 19. A second similar plate 2O is shown, somewhat shorter in length, this being fastened to the bottom 10 of the skip and atl but a short distance from the end or mouth ofl the skip. This plate also has the bearings 21 at its opposite ends, in which are pivoted the upper ends ofy the short arms 22, while their opposite ends 22 are pivotally mounted on the rod 23 which.

likewise, in turn, is mounted inthe bearings 24 on the superstructure of the paver. Extending between the two arms 22 and pivoted thereto is the plate 25, and also the angles 26., these members greatly strengthening, the supportk as a whole and giving the armsthenecessary rigidity. By glancing at the diagrammatic Figures 3, 4L and 5,;it will be seen that the mouth of the skips and the upper pivotal point of the shortarms 22 travel in the arc asv outlined by the dotted lines 27, while the nearly central portion of the back of the skip and the pivotal point of the arms 17, travel in the larger arc 28.

From Fig. 4 it will be seen that after the skip has reached` av position nearly midway of its, travel, the mouth of the skip will be nearly overl the hopper 7 and by the time the backl of the skiplhas reached a perpendicular position, the mouth will be directly over-the hopper 7. rllhis is an advantage as it prevents any, loss of material from the` mouth of the skip, as is often the case with the ordinary typeof skips now in use. The position-of the skip when ithas reached its uppermost position of travel is clearly shown in Fig. 5, the lower arms now being in a verticalor an upright position, the other arms having moved along the dotted lines 28 and extending substantially parallel with the bottom of the skip.

By glancing at these three figures (Figs. 3, l and 5), it will be seen that the pull on cable 5, to start with, will cause the skip to elevate, the mouth of the skip starting directly upwardly and `inwardly while the nearly central portion of the back of the skip terials to start to,v flow from the skip much c more quickly than were they skip. elevated from a single pivotal point, and moved through a long arc.

By pivoting the long'y arms 17 and the short arms 22, respectively, to plates which extend across the bottom of the skip, the skip will be elevated and travely through. its path of movement without tilting towards its opposite side or in` other'.v words, will be rigidly supported and held from. side sway which often causes the material to splash from the sides of the skip. l

From the foregoing it will be seen that numerous advantages are obtained, by providing two sets of supports, one set of whichl will be longer thany the other, and. whereint their inner pivotal points are eccentrically arranged. The skip may be elevated` more quickly than the usualitype of skip now inuse, and the material will also start flowing more quickly from the skip-while the vmouth of the skipl will travel slightly upwardly.l and inwardly at its initial movement towardsthe high hopper and will reach it before the relatively short back assumes a verticalposition. The skip and ,the supporting, parts may be readily assembled, are relatively cheap to manufacture` andv have proved highly eliicient .and economical .inl operation.

Many slight changes might-.be madef with.- out in anyway departing from `the spirit and scope of my invention.

Having thus described the same, what lv claim as new anddesire to secure by Lettersl Patent is 1. In a concrete paver having a rotatable mixing drum, a loading skip for charging said drum, pivotal sets of arms for guiding and supporting said skip in its movement, a brace extending across one set of arms, bo-th sets of arms being eccentricallv mounted to the paver'at their inner ends and pivotally mounted near the mouth andr center of the back of the skip respectively so that a movement ofthe skip will cause the mouth and the central portion thereof to move through arcs of eccentric circles.

A concrete paver comprising in part a rotatable mixing drum, a loading skip for charging said drum comprising a back and bottom substantially at right angles to each other, arms pivotally secured near the mouth of said skip, further pivotal arms of greater length secured near the center of the bottom of the skip, and each set of arms having separate inner aires so that the back of the skip tips with relation to the mouth while the skip is being elevated and the mouth of the skip approaching the drum during its upward travel.

3. A loading skip comprising a back and bottom extending at substantially right angles to each other adapted to be secured to a concrete paver, a plurality of supporting means pivotally mounted. to said skip and the inner ends of said supporting means being eccentrically mounted on the paver, the inner pivotal points being so positioned that an initial upward movement of the skin will cause the mouth thereof to move upwardly and inwardly, and the remainder of the skip to move upwardly and slightly Ioutwardly, while a continued movement of the skip will cause the remainder of the skip to move upwardly and inwardly to thereby discharge the contents.

4. In a concrete paver having a rotatable drum and hopper for the same, a loading skip the bottom and back of which extend at an obtuse angle to each other for charging said drum, means for supporting said skip comprising two sets of pivotal arms eccentrically mounted with relation to each other at their one end to the paver, one set of arms being pivotally secured at their outer ends to the skip and near its mouth, and the other set of arms being pivotally secured to the bottom of the skip near the center, the length of said arms and the position of their central axes being such that when the back of the skip is in an upright position, the mouth of the skip will be over the hopper and the bottom of the skip will rest on and be supported by the set of arms secured near the center yof the bottom.

5. A concrete paver comprising in part a rotatable drum having a hopper therefor, a loading skip for charging the drum, two sets of supporting arms pivotally secured to the skip at their one end, and pivotally secured to the paver at their opposite ends, the two sets of supporting arms being of different lengths and having eccentrically positioned axes so that when the skip is elevated, the mouth of the skip will be over the hopper when the bottom of the skip is in horizontal position and a continued movement from this point causing the material to flow into the hopper, the longer set of arms being so arranged that when the skip is in its upright position, substantially onehalf of the bottom rests ou and is supported by these arms.

6. A. concrete paver comprising in part a rotatable drum, a hopper for the drum. a loading skip comprising a back and bottom extending at an obtuse angle to carl; other for charging the drum, a pair of arms pivotally mounted to the paver beneath the hopper and also pivotally mounted to the bottom of the skip near its center, a second pair of arms of shorter length than the first mentioned arms pivotally connected to the paver and the pivotal point being below that of the inner pivotal point of the first mentioned arms, and at a distance further removed from the hopper, the outer ends of said last mentioned pivotal arms secured to the skip and near the mouth thereof whereby from the initial movement as the skip is elevated, the double pivotal action will cause the mouth of the skip to swing inwardly as the remainder of the skip is elevated and to cause the material to discharge when the bottom of the skip is in a plane higher than the mouth.

7. A loading skip for concrete pavers comprising a back, a bottom and merging side walls, pivotal arms secured to the bottom of the skip, a second set of pivotal supportino arms mounted on the bottom of the skip anc near the mouth thereof, the said arms being of different lengths and adapted to be eccentrically mounted on the paver so an upward movement of the skip will cause the mouth to swing upwardly and the skip to tilt forwardly and the first set of arms so arranged to support the skip along its bottom and prevent a side swaying movement when the skip approaches its filial elevated position.

8. A concrete paver comprising a rotatable drum, a hopper therefor, a skip for recharging said drum, the said skip comprising a bottom and back extending at an obtuse angle to each other and side walls merging with the back and the bottom, two sets of supporting arms pivotally mounted at their inner ends to the paver and positioned eccentrically with relation to each other, one set of said arms being pivotally connected to the bottom of the skip near its mouth and a plate secured to the bottom of the skip extending between the said arms and the second set of arms being pivotally mounted on the bottom of the skip and rearwardly of the first set of arms and a plate extending between these arms and secured to the bottom, the inner pivotal point and the length of both sets of arms being such that when the skip is raised so the back assumes a vertical position the mouth of the skip will be over the hopper and the plates and one set of arms forming substantially a platform for supporting the skip against a swaying or tilting movement.

9. In a concrete paver, a rotatable drum having a hopper, a skip comprising a bottom and back extending at substantially right angles to each other and open at its forward end having` a double pivotal action mounted on said paver, a cable for raising said skip, the pivotal action of the skip and 5 the arrangement of the cable being suoli that the pull on the Cable is tangential at the initial upward movement or" the skip, the

back of the skip travelling through a larger are than the mouth so that the material Will not flow from the skip until the mouth is 10 over the hopper.

In testimony lwhereof I affix my signature.
