.BLANK-LOCATING MECHANISM.

Application filed January 28, 1524. Serial No. 688,953.

To all w/mme't many concern:

Be it known that I, ABRAHAM .NovIoK, a citizen the United States, and a'resident of Flushing, county of Queens, and

State of New York, have invented certain new and useful Improvements inBlankl ioeating Mechanisms,- of which the following is a specification. I V

This invention relatesto meansfor align ing and centering blanks, particularly enve-lopeblanks in envelope making machines and the like, and holding them incentered position until they are engaged by subsequent operating mechanism. I

In the preferred form of embodiment of the invention, the aligning and centering of the blanks is accomplished by a pair of jogging fingers, which fingersare given an orbital movement, the operating stroke of which is in the plane of the blanks and the return strokeof which is out of the plane of the blankssothat during this return stroke a new blank maybe inserted into position for being acted upon by the jogger. A distinct saving oftime is thus made and the machine is rendered capable of a high speed of operation. I v

In accordance with a further featureof the invention, the jogging fingers are arranged tomove in convergingplanes so that the operation of the jogging fingers causes not only alignment of the blank but centering thereof as well. This feature is of particular importance for blanks which are relatively long and therefore difficult to center.

According to still another feature of the invention, mechanism is provided for impressing on the joggers movement which is translational as distinguished from rotational, so that adjustment of the mechanism for blanks of different seizes may be made without disturbing the orbitalmovement of the jogging fingers.

Various other features and advantages, included within the objects of the invention, will appear as the description of the invention proceeds. 7

Certain features disclosed but not claimed herein are disclosed and claimed in my pending applicatiom-Serial.No. 673,049, for bot-tom folding mechanism, filed November 6, 1923, and in my pending application, r Serial No. 631,576, for mechanical movement, filed April 12, 1923.

Referring now tothe drawings which illustrate a preferred form of embodiment of the invention, together wit-lrsuchpartsof the envelope making machineas are necessary toillustrate the operation of the same,

. ward on ,thebelt 2 under the weighted friction rollers 8, which fri'ct-ionally hold the blanks, upon the belt so that they travel forward therewith, but permit them tobe centered relative to the forming blades 3 and the folding mechanism.

.Atthelower end of the forming blades 3, .theblanks contact with stops 9 which are mounted on a hart) which constitutes apart of the lower flap folding mechanism described in my co -pending application. Serial No. 673.049, filed November 6, 1923.

The position of stops 9 on bar 9 is rendered adj ustable by means of screw woo-operating with-a. series of threaded holes 11 in the bar 9 so that the various seizes of blanks may be accon'imodated.

As the blank isv brought to rest against the stops 9, it is centered and broughtinto proper alignment by the action of thejoggerfingers 12, so that the blank may then be accurately foldedinto the desired shape or subjected to other Operations necessary for forming the desired envelope.

Each jogging finger 12 is provided with an Operatingor tip member 13 adjust-ably mounted upon the end of the .fin'ger12 by meanes of a telescoping tube 13 which is held in ,position by a set screw 18". jEach finger 12 is bent into ,a-right angle 12, and the end opposite the member13 ismounted for longitudinal and angular adjustment in a holder 14 Which is provided with aset and slides 19 and 19.

screw 1 1 and a key 14 for loosening or tightening the screw 1-1 when the finger is to be adjusted.

The holder 1% is carried on the end of a slide 15 which passes through a guide or housing 16 provided with a cover plate 16 and is provided with a roller 17 at the end opposite the holder, for cooperation with a cam surface to be described later. Projecting from one side of the housing 16 is another housing or guide 18, with a cover plate 18 for the slide 19 which carries a finger 2O projecting into a slot 21 in the slide 15. The other end of the slide 19 is provided with an oval shaped slot 22 for receiving one end of the flattened rod 23, the other end of which is received in a similar slot 22 in the slide 19" of the other half of the jogger.

The guides 16 and 18 are rigidly mounted upon a stationary part 24 of the machine, upon which is also mounted the rod 25 can rying the lever 26 for operating the rod 23 The lever 26 comprises a hub portion 26, which turns upon the rod 25, an arm 26 connected with the rod 23, and an arm 26, carrying the cam roller 27 for cooperating with the cam 28. A spring 29 holds the roller 27 in contact with the cam at all times.

A cam shaft 30 carries the cam 28, the cam members 31 and 32, and other cams for operating the various parts of the machine in properly timed relation.

The operation of the jogger is as follows:

At the initial position illustrated in Figure 1, the tip members 13 of the jogging fingers, are approximately in the position illustrated in Figure 3. When the rollers 17, which are held in contact with the cams 31 and 32 by the springs 33, travel to the low side 31 of the cams 31 and 32, the fingers 13, which are then in the plane of the blank, are drawn downward in converging planes Z (Figure 2), which intersect the angle between the top and side flaps of the envelope blank. The blanks are thus aligned against stops 9 and because of the converging component of the downward movement are si multaneously centered laterally. The latter feature is of particular importance when the blanks which are subjected to the align ing operation are relatively long, as will be readily understood.

In Figure 1, the movement of the jogging lingers is illustrated by the diagram A, the direction of movement being illustrated by the arrows, It will be observed during the downward movement described above, the tips of the jogging fingers are in the plane of the blanks. At the end of this movement the fingers are withdrawn from this plane, this withdrawal being brought about by cam 28, the low side of which at this time passes under roller 27 of lever 26, thus permitting spring 29 to turn the lever clockwise in Figure 1 so as to draw out the slide 19 and draw the slide 15 toward the bottom 16 of the guide 16. At the completion of this movement the tips 13 are to the rear of the plane of the blanks and while in this position, they are returned to the upper part of their stroke by the action of roller 17 which now passes over the high side 31 of cams 31 and 82. Because of the fact that the jogging lingers during the entire period of their return movement are behind the plane of the blanks, the blank previously aligned may be withdrawn from its position stops 9 (this withdrawal being effected by mechanism indicated at 9 in Figure 1, the construction of which, however, need not be considered for the present purpose) and a new blank may be inserted into position for alignment so that considerable economy oi time and therefore rapidity of op ration, may be realized. fit the end of the upward movement, the jogging fingers are again caused by cam 28 to move forwardly into the plane of the blanks, whereupon the entire cycle of operation is repeated.

It may be observed here that the length of the slot 21 is greater than that of fiHQEJ O of slide 19, so as to permit the slide 15 to move longitudinally with reference to slide 19, and the slots 22 in slide 19 are longer than the flattened sides of rod 28 topermit rela tive sidewise movement of the rod in the slots.

it is to be noted that the adjustment of the lingers 12 by sliding them in and out of the holder 1-2; or by turning the holder relative to the slide 15, does not disturb orchange the orbit A through which the joggers travel, asthat is determined by the path of movement of the holder 14 on the end of slide 15, which path is unaffected by the adjustment. While the path traveled by the poll vs 13 has been referred to as an orbit, he movement of the points 13 is not one of rotation but one of translation and comprises four compon nts. namely. downward, rearward, upward and forward, and all the movement is in a plane substantially as indicated at Z in Figure 2, the downward movement being in the plane of the envelope blank and the upward move ment being in. the rear of this plane.

llhile the movement of the jogger under the influence of too high and low points of the cam has been described, it is to be understood that the shape and position of the cams and the shape of orbit A as illustrated and described, is not intended to be mathematically correct, but is largely diagrammatic for the purpose of illustration.
