The present invent-ion relates to photography, and more particularly to apparatus 'for conveying prints through a delinite path, such as through successive baths for treatment. lt is also in the nature oi an improvement uponv the apparatus disclosed and claimed in my prior lPatent '#1,421,079 issued June 2*", 1922.

An object ot the invention is to provide improved and simplified means for disengaging the prints or sheets from the conveying means, and for depositing them at a delinite location, after the treatment has been completed; whiehwill operate with certainty; which will insure quick and positive disengagement of a print from the conveyor with a minimum otmutilation of the print or sheet; which will be automatic in action; which will not require attention or super-v vision by the attendant or operator; and which will be relatively simple, dependable, durable and inexpensive.

Various otherv objects and advantages will appear from the following description oit an embodiment of the invention, Vand the novel features will particularly be pointed outliereinater in the appended claims.

In the accompanying drawings:

Fig. yl is side elevation of ar portion ot photographic apparatus of the commercial or copying type, to which has been attached print releasing means constructed in accordance with the invention, the print releasing means being shown in the poised or set position ready for operation;

2' is a plan ot the same;

3 is a side elevation, on a different scale,iot' the print releasing means at about the instant when it becomes active to release a print; i

Fig lis an elevation similar to Fig. 3, Abut showingthe relative positions ot the parts just a'ltervthe kicker member-'has diseno'li ed a print troni the impaling means; i g 5 isa sectional velevation somewhat similar, to Fig. 3, but showing lull parts otherwise more or less hidden Fig. 3; and

illustrated embodiment of the inillel endless flexible `tegether at one or more intervals by cross bars 2 and the endless members with the bars constitute what may be referredto as a conveyor. The endless members l vmay be of any suitable construction, such as endless chains, and mav be guided through a desired pat-h of travel by suitable pulleys or sprockets 3 so that the endless members may move successively into and" out of l suitable chambers or `tanks (not shown) as'disclosed in my prior patent hereinabove referred to. After leaving the last tank however, the endless members are conducted in an approximately horizont-al direction, as shown in Fig. l, for example over a receptacle el into which the prints are to be deposited. i

Each cross bar Q-is provided with one or more spears or pins 5 for piercing or impal- .ing and carrying therewith a sheet or print G. Y They spears or impaling pins 5 preferablv extend from their bar in the direction out travelof that section of the conveyor formed by the endless members andthe cross bars, in order that any d ag on the prints will not pull them oit over the ends of the pins upon which they are impaled.V Y

' In the particular illustrated example, the

y conveyor atterpassing over the receptacle t into which theprints are to be dei/posited passes over a sprocket wheel 3and then passes in a return direction above and in spaced relation tothe stretch of the conveyor which is over the receptacle el.

A shaft 7 extends between and is rotatably supported by the opposite side walls of the apparatus preferably above the upper stretch of the conveyor.` Arms 8 are fixed to the opposite end portions of the shaft 7, depend along the sides of the conveyor, and then toward one another into the space between the stretches ol the conveyor. A U-shaped piece 9 is secured byone ot its arms to the ei-:treme free end of each arm 8. The other arms otl the pieces 9 at opposite sides et' the conveyor are connected together by a bar l0. The dis- Atf-ince between the U-shapcd pieces 9 is less than the distance between the endless members or chains l, sov that the bar l() may pass through the plane'o' two corresponding and connected stretches ot theendless members l.

T he arms 8, lJ-shaped pieces 9, and the connecting bar l0 together serve, and may hereinatterbe mentioned as, a kicker or striker :ueber or device. The U-shaped pieces. Q,

lll'

Lil

are positioned with their open ends extend-- ing forwardly in the direction of their travel during a s-:triking operation which will be in the direction of travel of the lower stretch of the conveyor immediately above the receptacle l, so as to clear each cross bar 2 by embracing it when the bar passes through the conveyor between corresponding stretches of the endless members in order to engage or strike the print carrie-d by that particular bar 2 as shown in Fig. f1.

An arm or lever 11 is also lined upon and depends from the shaft 7 at one side of the apparatus, and at its free end is pivoted by a pin 12 to one end of a lever 13 which is in turn pivoted by a'pin 1% to an intermediate section of a lever 15. The lever 15 is pivoted at one end by a pin 1G to a suitable bracket 17. A helical tension spring 1S is connected at oneend to the free end of the lever 15, and at its other end is anchored by a pin 19 to a suitable part of the apparatus, so as to urge or bias the lever 15 yieldingly into the position shown in AFig. Zl, in which it and the spring extend in the saine general direction and are in substantial alignment with one another, that is7 in a dead center position. The levers 11 and 13 which constitute a toggle connection between the lever 15 and the shaft 7 of the kicker member, are of such length that they will be in a broken or acute position when the spring 1S and the lever 15 are substantially aligned as shown in Fig. L1'.

Obviously then, when the toggle levers 1l and 13 are moved into a straight line or dead center position, as shown in Figs. 3 and 5, the spring 1S will be tensionedto a greater extent than that which it possesses in Fig. Il. lVhen the toggle. levers are moved past dead center position and into the position shown in Fig, 1, the spring` 18 will tend to continue the move-ment, but such movement will be limited by a pin 2O disposed in the path of one of the toggle levers, such as 11. 'lhis limited position is shown in Fig. 1, and the arms o l the kicker member are so fixed upon the shaft. '7, angularly with respect to the toggle lever 11, that the cross bar 1t) of the kicker member will be poised or held above the plane of the lower stretch of the endless lonveyor section which i; shown in Fig. 1, when the toggle lever is against the limit piu 2t).

il shaft 2l is mounted in a suitable bracket 22 attached to the iframe of the apparatus at one side thereof. An arm or rigger is fixed to the shaft 21, and extends upwardly into the path of travel of the cross bars 2 in the lower stretch of the conveyor section shown in Fig. 1, so that when a cross bar 2 strikes the trigger 23 it will oscillate and then release the shaft 21. A bell crank lever 2l is also fixed upon the shaft 21 for oscillation therewith, and one arm 25 of the bell crank en gages with a pin 26 which is carried by the toggle lever 13. Hence when the trigger 23 is rocked by any bar 2 it will rock the bell crank 21, and the latter will shift the toggle levers from the position shown in Fig. 1 to and through the dead center position shown in Figs. S and 5, v-shereupon Vthe spring 18 will snap the toggle levers further in. 'the same direction and carry the kicker member into embracing relation with the particular Cross bar 2 which actuated the trigger.

'lhe striking movement of the kicker member will be :from the rear and in the direction of travel of that conveyor section so as to strike any print thereon, drive it foiwvardly of its movement with the conveyor, and thus push it off of the .impaling pins. rilhe print will thereupon drop into the receptacle 1. rlhe other arm of the bell crank 2-1- 'arries a counter weight 2.7 which returns the trigger 223 and the shaft. 21 to their normal positions immediately upon their release. An abutment screw may be threaded through the bracket for engagement with the bell crank to limit its return movement, and thus by adjusting the screw 28 the initial position of the bell crank may be varied to sonic extent.

The shaft "I also has fixed thereto a reset arm 29 which depends within the path of the cross bars 2 after the lat ter have actuated the trig- 23 to release the kicker member. As a matter of convenience, the arm 2S) depends into the path of tl e cross bars in the upper stretch of the section of the conveyor which is shown in liig. 1. The engagement and operation of the i set arm 29 by a ross bar 2 causes a movement of the shaft 'T in a direction to 'anse the movement of the kicker 'niember out of the path of other of the cross bars 2 which are moving toward the paper release mechanisin. 'lhe shaft 7 in moving the kicker member to its poised or reset position also shifts the toggle members through dead center position and into the position shown in lfig. 1, wher t stop e Athey are held yieldingly against the or limit pin 2() by the spring 18.

1n the operation of this apparatus, the endless members' or chains 1 are driven in any desired manner, such as in prior patent referred to, and at a certain point inv their travel the prints or sheets are engaged (such as bv the ine-:nial of my prior patent referred to above) over the impaling points 5. so that the prints or sl eets will he drawn through a detinite path with the conveyor which path may include any number of developing, 1i):- ing and washing baths for the prints. i y

After the prints have been carried through ine oesired coarse tney approach the position shown in lll j. 1. villhen the cross bar carrying a print engages with the trigger ,shaft 21 and the bell crank 21 will be rocked,

and the latter acting upon the pin 26 will L s a t the toggle levers Vthrough dead center poion, whereupon the spring 1S will snap the V er .inen'iber from the dead center position the ovvn in Fig.- 8

or sheet forwardly and oit' of the impaling pins as shown in Fig.v 1i.' rThe print thus released drops into the receptacle i or upon any Cil platform provided at that point.

`During continued n'iovement of the conveyor, the cross bar 2 Will engage With the rcset arm 29 and reset the kicker member in the manner eiipifined. riieaction is thus antomatic, and vtl 1print ersheet is disengaged by pushing oilj the impaling meansin such a manner that there is practically no mutilation ol the print or sheet. The receptacle 4 may, if desired, contain a final fixing or Washing liquid, as shoivn'in Fig. 4, although it may merely constitute a receiving basket.

It Will be obvious that various changes in the varioiis details, which have been herein described and illustrated in order to explain the the nature of the invention, may be made by those s iilled in the art vithin the principle and scope of the iiiivention as expressed in the appended claims.
