TRIMMING OR SNIPPING MACHINE.

Application filed January 8, 1917.

To all whom t may concern.'

Be it known that I, EDWARD A. SALTER, a citizen of the United States, and resident of North Rose, in the county of Vayne and State of New York, have invented certain new and useful Improvements in Trimming or Snipping Machines, of which the following is a specification.

The present invention relates to trimming or snipping machines for' cutting olf the ends of string beans or other articles in which the lengths differor have variation, and an object of this invention is to provide a construction which will insure that the ends of the articles are brought to a certain position so that the proper amount will be trimmed or cut off. Another object of the invention is to provide an improved construction which will utilize a knife having a reciprocating or chopping movement. A further object of the invention is to provide a bunching mechanism which will form and hold the articles in a bunch so that they will not be displaced by the cutting mechanism.

To these and other ends the invention consists of certain parts and combinations of parts all of' which will be hereinafter described, the novel features being pointed out in the appended claims.

ings, l indicates a frame on which is mounted two shaftsQ and 3, the shaft 2, having two loose sprockets L thereon while the shaft 3 has two sprockets 5 secured thereto to turn therewith. About the sprockets 4l and 5, two sprocket chains 6 are passed, these chains being connected at intervals by cross pieces or guide bars 7, thereby forming an endlessr conveyer of the belt type. Mounted on the guide bars 7, for moving in the direction of the length of the bars, and transversely of the path of the conveyer are buckets or receptacles 8 which preferably have flaring side walls and open bottom walls, these buckets or receptacles being moved on the bars by a suitable mechanism, one form of which will be hereinafter described. A table 9 is arranged in such a manner that it closes the bottoms of those buckets on the uppermost lap of the conveyer so that articles deposited in the buckets will be confined therein during a certain portion of the travel of such buckets, the table being provided at l0 with an opening through which the contents of the buckets are discharged. Beneath this opening, an endless belt or other conveyer ll is mounted to conduct the articles discharged through the opening l0 to one side of the machine, and this conveyer may be driven from the shaft 3 by means of a bevel gear 11a on the shaft meshing with a bevel gear 1lb on a shaft 11 of the conveyer. If desired, this conveyer may have openings l1d therein, large enough to permit the tips of the beans to fall therethrough, but too small for the passage of the main portions of the beans, thus causing a separation of the tips of, the beans. These openings may be elongated transversely of the line of travel of the conveyer so that the main portions of the beans extend transversely of the openings. 'The material may be fed to the buckets 8 by any suitable means such, for instance, as an endless conveyer l2 which has its discharging end directly over the bucket conveyer to discharge into the bucketsdS as the latter reach such discharging en The bucket conveyer is fed by a step-bystep movement, this preferably being accomplished by providing a shouldered or ratchet wheel 13 on the shaft 3, and engaging such wheel by a tooth 14 on the end of a piston rod 15, the latter being eccentrically connected at 1G to a sprocket wheel 17 which is securedto the sha-ft@ so that thevshaft and' the sprocket wheel turn together. rThe sprocket wheel is given continuous rotation in any suitable mann'e'ras,` for in`stai1c`e,'by the sprocket chain 18 which also surrounds the sprocket wheel 19 on a shaft 20, the latter having also thereon a pulley 21 connected by' a'belt 22 to a pulleyv 23 on the shaft 24, which carriesalso a pulley 25 adapted to be connected by a belt 26 with a line shaft overhead;

Mechanism' provided for moving the buckets or receptacles Stransversely of the conveyer in'order" that the articles within the buckets or receptacles rmay'bebrought to proper positions'to befactedA upon by the cutting vI'nech'anism'- pusher-s2? and )28, one operating in advance ofthe other on a bucket to push the latter in one direction, 'while theother operates later on thebuc'ket to push the same' in the opposite direction. Inthi's instance7 these pushers :are connected together lfor simultaneons movement, andV to this end are in thejforn ofswingng arms pivoted' at-29 A"abov'eth'e uppermost "lap ofV thel conveyor and connected together by 'gear segments 30, so that as 'one y'moves' in one direction,4 the 'other moves'in the opposite direction. Preferl ablyfthefmovcment isefect'e'd by a cam'31 arranged onth'e" shaft 20- and having its operative face 32 engaging the arm of the pusher 27, to move the yla-tterin one directiony'this face 32 being rolling so'thatvthe pushing action is not continuous but 'is in the form of a 'series'of impulses so thatthev contents'of the buckets orl receptacles/are subjected to a jarring 'action Springs 33 acton the pushers'QTfand- 23 to Ymove the latter to-their normal positions. The pusher 27'jbeginsjto ac'ton 'its'bucket'or receptacle while the" bucketconveyer is moving, but

does noti complete its'shifting action funtil after the bucket conveyer has completed its movement one step.; This' shi fts the bucket or 'receptacle to one side of the line' or path of travel of the buckets. On Ithe nekt movement' of'fthe vbucket conveyer one step, the

This bucket moving mechanism, in this instance, embodies two" dragging action on the beans within the buckets, while the latter are moving endwise, two drag producing devices 34 and 35 are provided. Inthis instance, these elements are in the form of vertically movable brushes mounted in guides 36 on a cross piece 37 ofthe vframe 1, and arranged so that 'they do not: enter the buckets until the step-bystep movement is completed. The brush 34 enters the bucket which is being shifted transversely by the pusher 27 and engages the beans within such bucket, and the brush 35 enters the bucket which is being shifted by the pusher 23to engage the beans in such bucket. yThe engagementof -thebeans by the "brushes is 'comparatively slight, being suflicientto hold"the`be`ans against movement V'untill suclr beans are'l engaged by the end' ofthe bucket, aftenwhiclr the brush permits the beans to slip thereunder. Operation of the brushes may 'be effected by levers 38, which are"pivoted at`39 Ato the crosslrar 37i and haveftheii" free ends engaging'the brushes: at'40. Springs 41 act onthel'arm's 38' and tendto elevate theflatter with their brushes', while rollers 42 on the'pusher arms'Q? and 2S engage the upper surfaces of theL levers 33 and depress the latter vduring the latter part of the endwise movement of :theHV buckets.

"It is desirable to `employ a bunching mechanism'-which will operate upon vthe beans within Athe"*buckets or receptacles to bunch the latter prior to the shipping or s'eve'ring'bf the'"ends. In this instance a bunching mechanism is provided 'for Aeach of the pushe'rs',"tliis mechanism preferably comprising'a presser foot 43 and two grippers 44 operating o'n opposite sides of the presser foot. The pair of bunching mechanisms are preferably arranged on a single movable frame 45'wlii'ch is guided vertically on the frame 1 of the machine above the upper lap'o'f'the 'conveyerL A spring 46 tendsl normally tohold the bunching mechanisms in an elevated position out of the path 'ofthe buckets or receptacles, while a cani 471,' arrangedon the shaft"` 20, acts on the roller 4S to' depress the frame v45 to carry the two bunching mechanisms into two of the buckets or receptacles after the latter have bee"n"shifted endwise. The beans are lirst 'engaged bythe presser foot 43 which is mounted' on a slide'49 arranged on the frame 45. This slide 49 carries a pin 50 which worksin curved slots 51 in the grippers 44 and tends to move said grippers about their commonpivot'52, to' swing'their lower ends into'engage'ment with opposite sides of the bunch held by the presser foot 43, as will be seen more" clearly by 'referring to Figs. 5 and 6. lithA the raising ofthe frame 45, a spring 53 4acts on'th'e slide 49 and tends to move the latter with the Vvpresser foot 43 and the grippers 44 to their normal positions.

After the beans have been bunched, they are subjected to two snipping or cutting devices each of which is preferably in the form of a blade 54 carried by one of the arms of the frame 45 and brought into action during the latter part of the bunching action. A rubber or other yielding pad 55 may be arranged Linder each of the knives 54 to prevent the chilling of the latter.

' In the operation, beans are fed to the conveyer 12'and by the latter are discharged into the receptacles 8 as such receptacles reach the discharging end of such conveyer 12. After beans are received Within the receptacle, the pusher 27 is brought into action to shift the receptacle 8 transversely of the bucket conveyer, While the bucket or receptacle is being moved by the conveyer. This brings the beans against one Wall of the bucket and after the movement of the bucket conveyer has ceased, the sidewise or transverse movement of the bucket continues and at the same time the brush 34 enters the bucket and acts on the beans in such a manner as to hold against movement those beans which are not in engagement with the Wall of the bucket, so that such Wall Will eventually contact With all the beans, after which the brush will permit the beans to be moved relatively thereto. When the transverse or sidewise movement of the bucket is completed, the presser foot 43 engages the beans in the bucket and causes the grippers also to engage the beans to produce a bunch. During the latter part of the bunching action, the knife 54 Which is nearer the intake end of the machine severs or snips the ends of the bean in proximity to the end wall of the bucket. Upon the completion of the snipping action, the cutter and the grippers move first away from the beans leaving the presser foot in engagement therewith to strip them from the cut-y ter, after Which all of such parts are Withdrawn from the bucket. The bucket con` veyer now starts to move under the action of the pitman 15 and during this movement the pusher 28 cooperates with the bucket, Whose operation was previously described, to shift the latter into line with the other bucket. This shifting is not completed when the bucket conveyer again stops so that the brush 35 can enter the bucket 8 to operate upon the beans therein, in the same `manner as the brush 34 had previously operated, With the exception that the beans are now caused to engage With the opposite Wall of the bucket. When the bucket has completed its movement into line with the otherv buckets, the second bunching mechanism comes into operation to bunch the beans again after Which their other ends are severed. The beans with their severed ends are carried step-by-step to the opening l0 through which they drop onto the conveyer 1l which separates the tips from the main portions of the beans and carries the main portions to any suitable point.
