Claims.

Thi invention relates to a bottle chute and, vmore particularly,to a chute for guidingbottles down a vertical or inclined ,path, and-a retarder for overcoming the gravitational forces of the downwardly sliding "bottles.

One of the objects of this invention is-to provide a bottle chute having a retarder, the principal retarding effect of which occurs near the bottom of the chute, Another object, however, is to provide a retarding mechanism, a portion of which extends along the major part of the length of the chute. Still again, an object of this invention is to provide a retarding mechanism having a gradually increasing retarding effect which, at the upper portion of the chute-serves to decrease the speed of the bottles slightly as they pass through the upper portion of the chute andthen graduallyto decrease the speed of the bottles as they approach the lower end of the chute.

Still another object is to provide a bottle chute formed of rigid elements resiliently mounted whereby to prevent breakage ordinarily result ing when bottles hit against rigid elements. Ad-

ditonally, it is proposed to combine the functions -of the retarding mechanism and the resiliently ,yieldable elements to provide a self-eleaning-bottle chute.

Yet another object is to provide for the adjustment of the retarding mechanism near the lower end of the chute so that the velocity of the bottles as they emerge from the lower end may be altered. A furtherobject is to provide a structure automatically correlating the retardation of the lower. and upperretarding elements so that when the'lower elements are adjusted for-increased retarding effect; the retarding efiects of the upper elements are simultaneously increased. Still again .itis proposed to provide retarding-elements in the upper portion of a bottle chute having a constant retarding efiect near their upper ends, but in which the ratio of retardation between the lower and upper ends'may beincreased; thatds, it is intended to provide .a chute wherein no matter how greatly the velocity of the bottles may be decreased by the retarding structure at the lower end, the bottles will always be initially retarded gradually.

Still another object is to provide, in combination with the bottle chute, a receiving table resiliently supported at the lower end thereof for .gently receiving the bottles emerging from the lower end of the chute. It is further proposed to provide inclined surfaces on the receiving table for guiding the bottles from the path of succeedvrearwardly.

ing bottles emerging from the lower end of the chute.

' These and other objects will appear from-the following specification and drawings in which:

Figure 1 shows the combined bottle chute and receiving table in-perspective;

Figure 2 is a vertical section taken through the chute and receiving table;

Figure 3 is a horizontal section along the lines 33 of Figure 2;

Figure 4 is a horizontal section along the lines 4-4 of Figure 2; and

spectively, fitted-together the upper section in- -.cluding fixed front, rear and side walls 4, B, 8

and Ill, respectively, rigidly secured to one another by bolts 12. Itwill be seen that the upper section 3 is separable as a unit from the lower section 5 which includes fixed lower side walls I! and I6 rigidly secured to fixed front and rear walls 4 and 6 by bolts l2. Immediately below the lower edge of fixed rear wall 6, a pintle l8 .pivotally supports a lower rear wall section 20, the lower end of which is swingable forwardlyand In the front of the chute an intermediate section 22 of the front wall of the chute is pivoted at its top by pintle 24 so tht the lower end of section 22 may also beswung forwardly and rearwardly. Pivoted frontand

rear wall sections

20 and 22 are normally held parallel with the upper wall sections -4 and 6 by four resilient guide strips, comprising front .and

rear pairs

26, 26, respectively, the'u-pper ends of which are rigidly secured in thecorne'rs of the chute near the upper end thereof and extend finger-like down into the intermediate portion of the chute. It is thus seen that strips 26 resiliently resist rearward movement of front wall section 22 and likewise resist forward swinging of rear wall section 20 so that if it becomes necessary to clear the chute of bottles lodged therein, either of

wall sections

20 or 22 may be pushed inwardly after which strips 26 return them to normal position. When wall section 20, for instance, is pushed inwardly, a bottle lodged thereagainst is pushed againstwall sectionM at their lower ends. At the lower end of Figures 2 and 5, a stop 28 comprising a transverse strip secured to side wall l4 and I6 by screws 29,

prevents outward displacement of the lower end of the pivoted rear wall section 20.

Referring particularly to Figures 4 and 5, a clutch plate 30 is resiliently mounted'adjacent the lower end of the chute and by springs 32 extends through bores 34 through the side walls l4 and I6, the rear ends of springs 32being looped around rods 36 fitted in vertical slots 38 in the rear edges of the side walls. The front ends of the springs, which extend through suitable openings in plate 36, are looped around rods 40, the upper ends 42 of rods 40 being slidably engaged in suitable openings in the side walls, so that plate 36 may be moved forwardly against the tension of springs 32.

The front wall assembly is completed by lower section 44 suspended by links 46 from the lower end of pivoted section 22, the links 46 fitting into slots therefor and secured by pintles 48 to

sections

22, 44. As shown in Figures 4 and 5, lower front wall section 44 is provided with a shoe 50 abuttingly engaged by screw 52 threaded through a strip 54 which is riveted at 56 to plate 30 so that when screw 52 is threaded inwardly, lower I wall section 44 is thereby forced rearwardly,

The operation of the chute structure described above is as follows: When a bottle is placed in the upper end of the chute 2 and released, it drops downwardly between guide strips 26. The lower ends of guide strips 26 are normally held slightly pressed towards one another by lower front wall section 44 which, in turn, is normally resiliently held by springs 32 so that the distance between strips 26 and strips 26, and the distance between the inner sides of the front and

rear walls

26 and 44, is slightly less than the diameter of the bottles. Thus, the velocity of the downwardly sliding bottles is gradually decreased as they pass between strips 26. When the bottles engage the inner surface of lower front wall section 44, it resiliently swings forwardly against the tension of springs 32, thus to absorb most of the energy from the downwardly falling bottles. Being suspended by links 46, section 44 moves slightly downwardly as well as forwardly under the force of falling bottles to decrease the impact thereon. The final speed of the bottles as they emerge from the lower end of the chute may of course be predetermined by adjustment of screw 52 which determines the ultimate resistance of springs 32. It should be noted, however, that when screw 52 is rotated to swing section 44 inwardly and thus increase the retarding effect of springs 32, a slight rearward force is simultaneously exerted against section 22, thus, in turn, to compress the lower ends of strips 26 towards the lower ends of strips 26.

A particular advantage results from the articulation of

sections

44 and 22 through links 46 in that the chute is self-cleaning. That is, if a bottle should stick between

sections

29 and 44, the next succeeding bottle engaging strips 26 swings section 22 forwardly, thus to lift section 44 slightly upwardly and forwardly to free the lodged bottle before the next one reaches it.

At the lower end of chute 2, a receiving table 58 is resiliently supported by springs 60, table 58 being provided with inclined upper surfaces 62, 62 which form a V at the upper end of the table and an inverted V at the bottom of the table for deflecting the bottles to one side or the other from the path of the succeeding bottles emerging from the lower end of the chute. Finally a curved deflector plate 66 is pivoted at 68 at the lower end of the chute forguiding the bottles to the table. Receiving table 58 may also be used for inspecting and sorting bottles, which, by slight manual manipulation, may be deflected to one side or the other to roll down the inclined surfaces 62 or 62'.

In practice, the'chute may be of considerable length so as to extend between two or more floors and the receiving table may likewise be sufficiently long to accommodate a number of operators, the portions and dimensions shown being only by way of example and not of limitation.
