HOP-PICKER.

Specification of Letters Patent. Patentd NOV. 14, 1911,

Application led June 18, 1908. Serial No. 439,112.

l city and county of San Francisco and State of California, have invented new and useful Improvements in Hop-Pickers, of which the following is a specification.

This invention relates to hop-pickers, or devices for removing the hops from the vines.

The invention is applicable either as a device for picking the hops by hand, or for picking t-hem entirely by machinery; essentially the same principle being employed in either instance.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is a longitudinal section of the invention. Fig. 2 is a plan view partly broken away of a portion thereof. Fig. 3 is an enlarged plan of the stem-severing device. Fig. 4 is a transverse section taken on li-ne X-X, Fig. 8. Fig. 5 is a transverse section ofthe complete machine. Fig. 6 is a plan view of the picking, cleaning and vine-carrying devices. Fig. 7 is a section taken on line 3/-g/, Fig. 6. Fig. 8 is a longitudinal section of a modification of the invention. Fig. 9 is a detail sectional view taken on line z-a, Fig. 3. Fig. 10 is a detail elevation of the means for allowing adjustment of the picker fingers. Fig. 11 is a detail perspective view of a handpicking device. Fig. 12 is a plan of a modification. Fig. 13 is a side elevation of the same. Fig. 14 is a front elevation.

In the simplest form of the device, as shown in Fig. 11 for hand picking, A represents a bar or handle of suitable description, to which is secured any suitable number of curved and centrallybent spring picker members 2, preferably made of wire. These pickers are essentially A or V-shaped so as to inclose sharp crotches of any desired width, in which the hops are caught, These crotches or V-shaped loops, formed by suitably bending the wires in the manner shown and described, operate to engage the stems of the hops, and by a drawing motion either of the fruit against the device or .the device against the hops, the hops and clusters are easily and rapidly severed from the vines.

In Fig. 1, the same idea is carried forward into a machine in which any number of these pickers arranged in rows may be employed.

In the present instance, there is a series of upper cross-bars 3, each having its corresponding spring wire strippers or V-shaped pickers .4 similar to the picker members 2 first described. These upper series of bars are carried by the side bars 5, which latterV are supported pivotally on to the machine frame, and are vertically adjust-able at the ends, as shown at 6, to permit of a raising and lowering of the top series of pickers 4f,

with respect to a corresponding series of lower pickers 7. These lower pickers 7 ,are of similar construction to the upper pickers, and are carried by cross-bars 8 on the adjustable lower side bars 9. The cross-bars 3 and 8 are preferablyadjustably secured to the respective longitudinal side bars 5--9` in such fashion that the bars 3.-8 can be turned, more or less, to throw the upper and lower series of pickers more or less toward each other, and so vary the included angle, to effect the best results. Also, the finger bars 3 and 8 may be adjusted toward and from each other on the rails 5 9 by means ofthe blocksv in which the ends of the bars are supported; suitable means, as the bolts 56, working in slots in the side rails, serving to hold the blocks adjustably in position.

length. In practice, it is usually made about forty feet long and about siX feet wide.

Preferably the picking devices are arranged in deck formation, with a plurality of upper and lower series of pickers or fingers; the object being to cause the hopvines to turn over in their traverse through the machine, so that both sides of the hop vines will be twice or more acted upon, and the benefit be obtained of having the hops depend by gravity into the crotches of the underneathpickers. Thus below the set of pickers 4-7, I have shown a second set of the present instance I have shown a pair-of' The machine may be of any desiredl v about twelve feet. apart, more or less, ac-

I cording to the length of the hop vines. The

underneath plate carries a Xed jaw member 17 and a movable jaw member 18; this movable jaw member 18 being part of a lever 19 which is fulcrumed at 20 to one side of the jaw 17. AThe end of the lever 19 adjacent to pivot 20 is toward the center of the machine, and is provided with an overlapping guard portion 21 underneath which the y vines are laid and held in place. This lever and underneath. the guard plate 21.

19 is curved backward away from the direction of travel of the carrier 10, and the arrangement of the jaws 17-18 is such that the jaws may be opened out to allow the insertion of a hop vine or a bunch of vines; and the moment that the carrier moves forward in the direction of the arrow, Fig. 7 the jaws will be automatically closed by the pressure of the vines 18 against lever 19 These grippers slide over the underneath pickers and are supported horizontally thereon, and the top cover plate 14, when closed down over the vines, prevents the ends of the stems or the grippers 17-18 from catching in the pickers. l/Vhile the grippers with their load of vines are passing through the machine, the plates 14-15 will remain closed by the pressure exerted from the top f and below by the pickers; but whenthe grippers issue from the machine, and at a point approximate to sprockets 13, the`top plates 14 will drop down by gravity, and the outwardly projecting end 22 of the lever 19 will be tripped to allow the stripped vines to be discarded.

Any suitable form of tripping mechanism may be employed. As here shown, I pivot to anysuitable support a tripping device having two angularly disposed arms 23-24, so positioned normally that when a crossbar 26 carrying the clearing devices 25 comes along, this cross-bar, and the corresponding cross-bars 27-16, willmiss the first finger 23, but bar 26 will strike the second finger 24, and so lift the finger 23 immediately into the path of the approachingend 22 of a movable jaw lever 19. As soon as the end 22 strikes the finger 23,`the jaws -open and release the stripped vines. As

soon as the grippers have passed, the trip 23-24 drops down again into position ready for the next approaching gripper.l

machine point forward in the direction of travel of the carrier, and preferably the side bars 5 9 are inclined slightly toward each other away from the feed end of the device, thereby forming a more or less contracted space between the strippers or pickers, for

the purpose of insuring the proper entry of the vines and hops into the machine. In practice, it has also been found advisable to make the top series of strippers or pickers longer and more springy than the coperating lower set, and to have the A-shaped ends .of the upper strippers intermeshing more or less with 'the underneath strippers. These pointed springy ends of the strippers or fingers will thereby press upon the vines yieldingly, and dig into the vines in such a way as to engage the maximum quantity of hops and produce a cleaner picking of the vines. Also, in order to enhance the eili-y ciency of the machine it has been practical @and advisable to vary the planes in which :the pickers lie, so that not only the hops Vwhich stick up in the air and which hang downwardly will be caught and stripped from the vines, but also the hops which may stand out to either side will be likewise caught. Therefore, in the practical arrangement now employed, successive series fof pickers will be arranged so that one set of pickers will have its picking ends lying substantially in a horizontal plane, or in `the plane in which the vine travels.

The next set will be turned to one side, as to the left, at an angle of 30o or 40, more or less. gThe next series will be turned similarly to fthe right, while the series next succeeding will be more nearly horizontal, like the first, and so on progressively through the machine. These pickers which are turned to one side or the other may be designated as diagonal, or laterally-inclined pickers, or right and-left pickers; while the others may be called the flat or horizontal pickers. This arrangement of pickers is illustrated in Figs. 1 and 2, and it is understood that the upper and lower pickers of a set correspond. That is to say, there is an under- In order to clear the fingers of hops which These `cleaning devicesl 25 will spread the pickers apart, reaching into the crotches of the pickers and pulling out the hops, and on releasing the pickers will allow them to spring back and shake off anything that might otherwise adhere to them.`

In order to prevent the fingers from becoming gummed and clogged up as they will otherwise do, I arrange a cross-bar 27 between each pair of bars 16 and 26, and wrap this bar with felt, soft leather, or other suitable absorbent material, leaving a couple of flaps 28 to be saturated with oil, and to act as wipers for the stripping fingers or pickers. By this oiling arrangement it has been found that the strippers keep clean and bright, allowing the severed hops to fall freely away from the lingers, when cut off.

It is manifest that instead of the hops traveling between relatively fixed sets of stripping fingers or pickers, as above described, these stripping fingers may be mounted on upper and lower sets of endless carriers 47-48, as shown in Fig. 8, and the hops may be drawn between the adjacent parallel planes of the carriers 47-48 by any suitable mea-ns, as the cable 49; the two ,carriers 47-48 being so timed to travel in unison that there will be intermeshing or coperating sets of upper and lower pickers, similarly as hereinbefore described.

The hops which are taken off by the strippers in the first traverse of the vines through the machine fall onto the inclined plates 29, and roll thence off to either side, where they are caught by inwardly inclined plates 30 and directed in underneath the lowermost series of strippers on to the draper 31, whence the hops and clusters are carried to one end of the machine and deposited on to the separating screen. This separating screen preferably consists of an inclined frame 32, to the head end of which are anchored the separating wires 33. The lower ends of these wires connect with metal plates 34 arranged on edge, Figs. 3, 4 and 9. Suitable tensioning devices, as 35, are employed, by which the wires may be maintained taut. The lower end of the screen frame 32 is pivoted on a sha-ft 36, while the upper end is given a vibrating motion by any appropriate means, as the shaft 37 and cam 38, so as to cause the blossoms and clusters to `either go through between the wires and edgewise standing plates 34, or, in the case of clusters, cause the clusters which straddle the wires to slide down the wires on to the -sharp edged plates 34 and beneath the pivoted bars 39 when the latter are raised.

The bars 39 rest fiat on the sharp edges of the plates 34 and are individually fulcrumed on the shaft 36 on which the frame 32 is hung. There is a Separate bar 39 for each plate 34, and each bar has a limited rocking movement independent of all the other bars, provided for by the elongated kslots 40 and loose connected rod 41 extending through all the bars. The clusters which straddle the wires and slide down on to the cutting plates 34, strike against the front end of the bars 39 when they are down, and are prevented from rolling on over the bars by a shield 42 carried by each bar. When the bar is lifted these clusters can slide on down the plates underneath the bars, so that when the bars drop again they will coact with the plates 34 to sever the stems and allow the blossoms and fruit to pass down through. Any appropriate means may be employed to oscillate the bars .39. As here shown, a series of levers 43 are fulcrumed to the shaft 36, each lever carrying a cross-arm 44 extending over one or more of the bars 39, and each lever 43 acted on by respective cams 45 on a shaft 46. Any appropriate form of driving connections may be employed to give constant motion to the shafts 37 and 46, and the various other moving and operating parts of the apparatus. If desired, a plurality of these separating screens 32 may be employed, one arranged beneath the other but for the purpose of the invention it is onlyv necessary 4here to show one.

In practice, the operation of the apparatus is as follows: The various pickers and strippers 4 7 in the several series are first properly adjusted according to the fullness and character of the vines and hops being treated. The vines are gripped between the plates 14-15, and the conveyer 10 set in operation. The vines are thereupon drawn between the pickers, and the hops removed in the manner previously described. These V-shaped pickers operate in the manner of combs, in the angle portions of which the stems of the hops are caught and the hops stripped off. While-many of the hops are caught by an upper layer of pickers, most of the hops, since they are connected by their slender stems to the vines, more easily fall into the crotches of the underneath pickers, and are thereby removed; hence the object of turning over the vines and causing them to travel through the machine in a direction reverse to that first taken. When the vines have thus two or more times traversed the length ofthe machine, they are discharged by reason of the arm 22 on the movable jaw 18 striking the stop 24 and opening the jaws, whereupon the pressure on the vines being released, results in the vines dropping ott clear of the machine. The severed hops and clusters falling on the conveyer 31 are deposited on the inclined shaking screen 32; and such clusters as may straddle the wires 33 or plates 34: are severed from their stems by means of the cutters 89, as previously described.

In Figs. 12, 13 and 14, is shown a modiication of the invention, in which the picking lingers 50 are arranged on upright bars 51 arranged in panels 52-53, which panels are shown as arranged in succession and oppositely inclined. The hop vines are suitably supported from an overhead trolley carrier 54:, and these vines hang down so that when they are drawn across or between the panels 52*53 the hops will catch in the picker lingers 50 and be stripped from the vines. Instead of arranging the panels alternately inclined, and in succession, as here shown, they may be arranged side by side so as to inclose a V-shaped space between them, and the hops will be drawn through this gap or chasm formed between the panels. As the hops are drawn along they are turned over and revolved, so that all the hops on the vines will surely be caught in the fingers.

Having thus described my invention, what I claim and desire to secure by Letters Patent isl.
