@riginal `application. nleri September 2, 1913, Serial t'o. 787,745. Divided and this application filed June 29, 1914. Serial No. 843,043.

To all whom it may concern Be it known that we, MAX lDNNEBIER and ALFRED WINKLER, citizens of the German Empire, residing at Neuwied-on-the- Rhine, Germany, have invented certain new and useful Improvements in Delivery and Counting Mechanism, of which the following is a specification.

This invention relates to improvements in delivery and counting mechanism suitable for use in envelop and bag making machines such for instance as described in our copending application Serial No. 787,745 from which the present application has been divided out.

The main object of this invention is to provide improved means by which the bundling device, which may be of any kind, will not operate to separate the bundles unless the proper number of envelops has been passed into the stack or receptacle. Various forms of bundling devices are known and we have chosen only one to illustrate this invention, which however is applicable to other forms of bundling mechanism.

1t is not necessary here to illustrate the entire machine for making the envelops as this is described in greater detail in our copending application mentioned above. The counting mechanism is arranged at the delivery end and its moving parts are operated by suitable driving or transmission mechanism from the main driving shaft of the machine.

1n the drawings: Figure 1 is a side elevation showing the entire mechanism, one side frame of the machine has been removed together with clutch mechanism located on the shaft 123 externally of the removed frame. Fig. 2 is an end elevation of so much of the machine as is shown in Fig. 1. Fig. 3 is an end view of the external clutch, this view being similar to Fig. 2 from which this part has been omitted. Fig. 4 is a detail of the single revolution clutch mechanism and Fig. 5 is a further detail which is not distinctly visible in Fig. 4.

For the purpose of this invention the envelops passing from the machine are delivered into a suitable receptacle for the counted bundles. This receptacle is fashioned with a number of compartments and when the desired number of envelops has been filled in to one of the upper compartments,

the receptacle is moved on to bring a fresh compartment into position to receive the' envelops discharged. The envelops thus filled and counted in the compartments of the storage drum are delivered in bundles to the delivery stack.

The envelop passing from the roller 90 and sector 99, is taken up by a suction nozzle 108. The sector 99 is short and does not complete the transportation of the blank. The suctlon nozzle 108 completes the transportation or delivery of the blank and for -th1s purpose is mounted on a hollow shaft 109 (see Figs. 1 and 2) connected to a vacuum pump not shown by a dexible pipe 110. The hollow shaft 109 is adapted to be operated by a lever 4111, and a forked rod 112, which 1s provided with a roller engaging a cam 1.13, mounted on the axis of thek roller 90, sultable spring means, not shown, being employed to retain the roller in contact with cam' 113. The nozzle 108 is adapted to swing inthe direction of the arrow in Fig. 1 to transport the envelops downward and properly into the compartment for the time being immediate in position to receive these envelops.

The compartments are` open ended and formed by bars 115 fixed to a central hub 114. The hub 114 is mounted on a shaft 11.7 provlded with a ratchet wheel 116, so that the drum rotates in a vertical plane. An arm 118 is mounted to rotate freely on the shaft 117, and this arm is operated by a rod 120, which is forked at its lower end (see Fig. 2) and carries a roller 122 engaging a cam 121 fixed to rotate with the shaft 123. The shaft 123 is.operated from the main shaft. so as to rotate at intervals through a complete revolution and thereby the pawl 119 moves the ratchet 116 and shaft 117 through an angle suficient to bring a fresh nism so as to -rotate for one revolution with the main shaft. Means are also provided by which the forward feeding of the receptacles is cut out if the proper number' of envelops has not been delivered. The forward movement of the receptacles is thus not dependent wholly yupon the proper number of operations to the pawl, but is also directly dependent upon the proper delivery of twenty-five, or other desired number of envelops to the compartment.

On the shaft 123, a twentyfive toothed wheel 124, is loosely mounted. In this wheel there engages a pawl 125 mounted on an arm 126. The arm 126 is operated through a rod' 127 from the main shaft of the machine. This operation is effected through a cam on the main shaft which causes the rod 127 4to reciprocate. The stepby-step movemet of the wheel 124. brings a striker projection 129 against a lever 130 whereby the angle lever 130, 132, pivoted at- 131, receives a kick. The rod 133, which is coupled to the end of the arm 132 operates a member 134 (see Figs. 3 and 4) loosely.

mounted on the shaft 123, outside the frame of the machine. This externally projecting part of the shaft 123 is omitted in Fig. 1. Thehub of the member 134 is Aprovided with a projection 134a (see Fig. 5) opposite a roller 135a mounted on the end of atransverse lever 135.

The lever 135 is pivotally mounted at136 on a hub 137 ixed to the shaft 123. Alongside and in addition to the hub 137, a second hub 138 is loosely mounted which hub carries the chain wheel 139, and also the clutch ring 140, which resembles a ratchet wheel in shape. The member 134 is loosely mounted around the second hub 138. .When the member 134 is operated by the kicking of the lever 130--132, the projection 134 is moved from beneath the roller 135 on the lever 135, and this lever is pressed by its spring 141 downward, so that it swings about its pivot 136 into the path of the clutch projections on the clutch ring 140. The first projection to engage the lever 135 causes this lever andthe sleeve 137 and shaft 123 to rotate until the roller 135 again engages the projection 134a to raise the lever 135, against the action of its spring 141 out of engagement with the clutch projections on the ring 140. The rotation of the shaft 123 takes place inthe direction of the arrow H shown in Fig. 4. It will be understood that the chain wheel 139 is continuously driven from the main shaft of the machine and the action described for rotating the shaft 123, only takes pla-ce when the proper number of envelops has been delivered and counted by the counter ratchet 124. The means described as operated from the striker 129 thus constitute mechanism by which the envelops are automaticallyseparated into bundles of a desired predetermined number. As mentionedv above the rotation of the shaft 123 raises the rod 120 and thereby causes the pawl 119 to move the hub 114, through a suitable angle. The parts coming into operation for producing this eifect` lis arrested, and these assume the position shown in dotted lines in Fig. 1. The next following bar or bars 115 sweep the bottom ends of the envelops of the arcuate guide 143-from which they fall on to the table 147. Before this happens, however, the pusher 146, which is carried by the arm 145, is moved back by the roller on the arm 145 following the cam 149. The arm 145 is pivoted about the pin 148 and is held by means of a spring (not illustrated) with its roller against 'the cam 149. The parts 150, 151, 152 are arranged in a known manner to displace the successive bundles slightly as regards one another when they are pushed up by the pusher 146. Simultaneously with the retreat of the pusher 146, the fingers of the rake 153 are swung upward, in virtue of their carrying lever 156, which is pivoted at 154 to the side frame of the machine (see Fig. 2) following the cam 155. As soon as the pusher 146 has returned the bundle of 105 envelops intoproper position Iin the pile, the fingers of the rake 153, again swing into the position illustratedl in Fig. 1.

The means for preventing the forward feeding of the receptacle with the compartments for the bundles of envelops when the full number of envelops has not been delivered will now be described. More correctly the means to be described insures that the .single rotation of the shaft 123 is dependent upon the proper delivery of the proper number of envelops to any given compartment. When through any reason no blank is delivered from the sector 99 and roll 90 the suction nozzle 108 is not closed by the euvelop and in consequence no material vacuum is set up in the hollow shaft 109 connected to said nozzle. Alongside the nozzle 108, a hollow arm 158 is provided, also in communication with the hollow shaft, and inywhich a piston 157 is adapted to work against the action of a spring 159, when the suction action is set up in the hollow shaft. When no material vacuum is formed in the hollow shaft 109, the spring 159 maintains manana the piston 157 at its extreme outer position illustrated in Fig. 1. The piston 157, by its position determines whether or not the counter tripping mechanism herein described is operated or not, and its position is in turn dependent upon the engagement ot the suction nozzle with a blank. 'llhe tripping mechanism employed may be ot any convenient form and the following has proved suitable and eective: vThe piston has a rod 160 adapted, when the nozzle 108 swings downward and when the piston 157 is in the position illustrated, to engage with its roller end a lever 161 pivoted at 163, and carrying an arm 162 coupled by a rod 1611 to a twoarmed lever 166 and 167 pivoted at 165. rlhe arm 167, when oscillated bv the roller on the rod 160,'engaging the 5 rer 161 is adapted to strike against a tail a 1G58 on the pawl 125. The pawl 125 is thus held out of engagement with its ratchet 1 that the movement of the arm 1% t rod 127 does not 'teed the ratchet through one tooth.

1t will be understood that normally the piston 157 is drawn upward in Fig. 1 by the suction created in the hollow shait 109 and thereby draws the end 160 out of the path of the lever 161 and the stopping action above described only takes place when no blank is delivered. ln order to enable the rod 160 to pass the lever 161 in its extended position the end of the lever 161 is provided with a pivoted finger 161a which is tree to swing independently of the lever 161, when the rod 160 moves in the opposite direction to the arrow shown.

The tripping mechanism described may be coupled up in any well blown manner to the clutch tor putting the machine in and out of gear. i This mechanism is usual on high speed envelop making machines and need not be described more fully here.

'llhe invention may be applied to envelops and paper bags ot widely varying shapes and sizes.

We claim:

1. Means for delivering folded blanks in counted bundles comprising a receptacle having open ended compartments and rotatable in a vertical plane, means for delivering envelops to an upper compartment ot said receptacle, a ixed arcuate guide closing the open ends of said compartments, and terminating at the bottom of said rotatable receptacle, and a Xed stop above the lower termination of said arcuate guide and located to arrest the envelope, substantially as described.
