(o1. zes-es) i Claims.

The invention relates to counting apparatus and more particularly to apparatus for counting articles and has for its object to provide a simple apparatus of the indicated type for eciently counting articles which are successively and progressively advanced in a predetermined manner and which travel in operative relation to the novel apparatus.

The invention contemplates further the provision of a novel counting apparatus designed particularly for counting articles of uneven or irregular contour as exemplified for instance by bags o-r sacks of merchandise.

Other objects will appear from the description hereinafter and the features of novelty will be pointed out in the claims.

In the accompanying drawings, which illustrate an example of the invention without dening its limits,

Fig. l is a side elevation of the novel apparatus; m

Fig. 2 is a plan view thereof;

Fig. 3 is an end elevation of the novel apparatus;

Fig. 4 is a detail sectional view on the line 4-4 of Fig. 1;

Fig. 5 is a similar view on the line 5-5 of Fig. 1;

Fig. 6 is a corresponding view on of Fig. 1, and

Fig. '7 is a fragmentary side elevation lilustrating another arrangement of the novel apparatus.

In its illustrated form the apparatus comprises a supporting frame consisting of spaced upright members I '(only one o-f which is shown) and a transverse member i I extending between and carried by said upright members id, said members Ill and II preferably being constructed of metal having a channel form in cross-section. A longitudinal channelled supporting bracket I2 is fixed upon the transverse member 4I of the supporting frame in any convenient manner as by means of oppositely projecting lugs Iii and bolts I4. A pivot block I is pivotally mounted in any convenient manner in the channel of said bracket I2 preferably adjacent to one end thereof; in the illustrated example the pivot block I5 is pivotally mounted to rook upon a pivot stud I6 which projects upwardly from the bottom of the channelled bracket I2 as shown in Fig. l. The illustrated pivot block I5 is of substantially triangular form in cross-section and is provided with a flat upper face with which one end of a leaf spring I'I is in surface engagement. The

the line 5-5 arrangement further includes adjusting means whereby the pivot block I5 is rocked upon the pivot stud It and secured in an adjusted position to vary the normal position of the leaf spring Il for the purpose to be more fully pointed out hereinafter. In the example shown in the drawings, the aforesaid adjusting means serves also to secure the end of the leaf spring I1 in surface connection with the pivot block I5, and comprises a pivot plate I3 and bolts I9. The latter pass through the spring I'I and through suitable openings in the bottom of the bracket i2 and through openings in the pivot block I5 and pivot plate it and are screwthreaded at their upper ends for the accommodation of adjusting nuts 2i) and lock nuts 2l. The nuts 20 bear against the pivot plate I3 and in cooperation therewith clamp the end of the spring I1 in surface engagement with the pivot block I5 as illustrated in Fig. 1. These nuts 2i) serves also to rock the pivot block I5 on its pivot stud I6 as will be more fully explained hereinafter.

The apparatus further includes a yieldable suspension frame consisting of carrying members 22 located in spaced parallel registry With each other and forming preferably integral parts of a bearing sleeve 23 pivotally mounted by means of a pivot pin 2li between lugs 25 which depend from the bracket I2 in spaced parallel registry with each other as shown in Fig. 5. The suspension frame further includes suspension members 2G located in spaced parallel registry with each other and each having one end pivotally connected at 2l with the outer free end of the leaf spring Il which, as shown in Fig. 1, extends lengthwise of the channelled bracket i2 and outwardly beyond the same. The other ends of the suspension members 2t are ypivotally connected by means of a bolt-22 or its equivalent with the carrying members 22. A tracer wheel 29 is rotatably mounted on the 'pivot pin 28 between the suspension members 2b as shown in Fig. 4.

A control wheel 3i) of smaller diameter than the tracer Wheel 2d is rotatably mounted by means of a pivot bolt SI or its equivalent, upon an arm 32 which itself is pivotally connected at with the preferably downwardly curved end 22e of the one carrying member 22 as shown in Figs. 1 and '7. A carrying bracket 34 is carried by the yieldable flexible suspension frame and in the illustrated example is fixed upon one of the carrying members 22, said bracket projecting upwardly from said carrying member 22 and terminating at its upper end in a horizontal support 35 upon which a counting device 36 of any conventional type is secured; the illustrated counting device 35 includes an operating member 37 and the customary counting discs 38 visible through a slot 33. The carrying bracket 34 further carries an electric switch 40 which includes an operating member 4l and may be included in an electric circuit designed for instance to bring about the automatic discontinuance of the operation of an element or elements associated with the novel counting apparatus. As shown in Figs. 1 and 3, the arm 32 is connected by means of la link or operative connection 42 with the operating member Ill of the switch 48, and said operating member 4l in turn is connected by means of a link or operative connection 43 with the operating member 31 of the counting device 3S. In some arrangements the switch 40 may include counting elements in which case the link 43 and the counting device 33 m-ay be omitted, or said counting device 36 simply be disconnected from the operating member 4| as shown in Fig. 7. In other arrangements the arm 32 may be directly connected with the operating member 31 of the counting device 33 in which case the switch 45 may be omitted or simply remain disconnected from the arm 32 and the counting device 35.

In the operation of the novel apparatus the yieldable suspension frame and its associated elements may be raised by the articles being counted and in such case will drop back, between successive articles, by gravity assisted by the leaf spring il, to the initial normal position shown in Fig. l. For the purpose of cushioning this return movement of the parts, the apparatus includes a cushioning means which in its illustrated form consists of a bearing block 44 mounted at a suitable point between the carrying members 22 and provided with an aperture 45 which extends therethrough as shown in Fig. 6. A stop rod extends slidably through the aperture 45 and is pivotally suspended by means of a pin 41, from lugs 48 which depend from the channelled supporting bracket l2 as illustrated in Fig. 6. An impact receiving cushion 49 preferably made of rubber or other resilient material, is mounted upon the stud rod 45 below and in engagement with a bearing block 44 as shown in Fig. 6. The cushion 49 rests upon a washer 50 mounted on the rod Il@ and adjustably xedv in place thereon by means of a nut l and a lock nut 52;

In the illustrated example, the counting. apparatus is of a form particularly designed to count articles of uneven or irregular contour as eizemplied, for instance, by bags or sacks of merchandise A. The latter are progressively moved over a given path and pass in operative association with the counting apparatus, for instance, by means of a travelling conveyer 53 of any conventional type and operated in any convenient manner.

In practice the pivot block l5 may be rocked on the pivot stud l5 by loosening the nuts 20, 2l on one pair of associated bolts i9 and then screwing the nuts 2li and 2| of the other associated pair ci bolts i9' downwardly thereon so as to develop pressure at one edge or the other ofthe pivot plate lil andr in turn the pivot block I5 to rock the latter on said pivot stud |13. Dependent upon the direction on which the pivot block l5 is thus rocked, the leaf spring l-'I will be correspondingly adjusted to either raise or lower the outer end of said spring l1. This adjustment of the spring il will correspondingly raise or lower the suspension members 25 and pivotally swing the carrying members 22 to thereby raise or lower the tracer Wheel 23 and its associated control wheel 30 to a selective initial normal position. It will be noted that the carrying bracket 34 and the devices 33 and 40 mounted thereon together with the elements associated therewith will partake of the aforesaid movements of adjustment. In this way, the normal position of the tracing wheel 29 and its associated control wheel 3G may be selectively varied in accordance with the di` mensions or other physical characteristics of the articles to be counted. In all of the normal positions of the tracer wheel 2S the associated control wheel 33 normally projects beyond the periphery thereof as illustrated in Fig. 1.

In describing the operation of the illustrated novel counting apparatus it will be assumed that it is being utilized for the purpose of counting sacks or bags of merchandise A which are being conveyed over a predetermined path by the conveyer 53 or its equivalent. It will be understood that this is not to be construed as defining the limits or usefulness of the novel counting apparatus and that the following description is intended to exemplify the operation of the apparatus in whatever field it may be utilized. As a sack or bag of merchandise A or other article passes in operative relation to the apparatus, the control wheel 3l) will come into rolling engagement with the upper curved or other surface of the sack or bag A or other article being counted. At approximately the same time, or in proper operative timing, the tracer wheel 29 will likewise come into rollingr engagement with said upper surface of the sack or bag of merchandise A or other article. As the advance of the bag or other article A continues relatively to the counting apparatus, the control wheel 33 will be shifted upwardly by the sack or bag of merchandise A, or other article, until the periphery of said control wheel 30 registers with the periphery of the tracer wheel 29, as shown by dotted lines in Fig. 1 and accordingly will swing the arm 32 upwardly on its pivot 33. This pivotal movement of the arm 32 will exert an upward pushing force on the link Il?. and will swing the operating member 4I upwardly to thereby cause the switch 42 to operate and perform its functions and at the same time will cause the operating member 4l to transmit an upward push to the link 43 whereby the operating member 31 will be actuated to operate the counting discs 38 of the counting device 3G in the well-known way. As the advance of the Sack or bag of merchandise A or equivalent article continues, the tracer wheel 23 and the control wheel 30 will roll along the upper surface of said sack or bag of merchandise A and the control wheel 3i) will nally return to its normal position illustrated in Fig. 1 ready for contact with and operation by the next succeeding sack or bag of merchandise A or equivalent article as the same is carried along by the conveyer 53 or its equivalent. The tracer wheel 29 will correspondingly roll along the upper surface of said sack or bag of merchandise A or other article and if the dimensions of the latter require it, will yield upwardly against the tension of the leaf spring Vl; in other words, the yieldable suspension frame on which the tracer wheel 2S and its associated elements are mounted will be pivotally actuated relatively to the lugs 2-'5 against the tension of the leaf spring I7 to permit this upward yielding of the tracer wheel 29 if this should be necessary. The carrying bracket 34 and the switch 43 and counting device 36 partake of these yielding movements of the aforesaid suspension frame.

As the travel of the sack or bag of merchandise A or equivalent article continues, the tracer wheel 29 will continue its rolling travel along the upper surface of said sack or bag of merchandise A, or other article, and the suspension frame with the elements carried thereby finally will return to the initial normal position occupied thereby, this return movement being effected by gravity assisted by the tension of the leaf spring l1. If the surface contour of the article being counted is such that the control wheel 30 and tracer wheel 29 abruptly drop therefrom when said article has been advanced beyond the same, the aforesaid return movement of the parts will be yieldingly arrested by the cushion 49 coming into engagement with the bearing block 44. In such event the developed impact will be neutralized without strain upon the elements of the apparatus, and in any case the return movement of the suspension frame will be arrested to restore all of the elements of the apparatus to their initial normal position without injury or strain. As the next successive sack or bag of merchandise A or other article is advanced by the conveyer 53 or its equivalent, and passes in operative relation to the counting apparatus as previously described, the parts again will be operated by said successive article in the manner set forth to record the same on the counting device 36.

Because of the fact that operated elements of the apparatus including the counting devices are all mounted upon a common support, as exemplified by the yieldable suspension frame, the operative relation between said elements remains undisturbed at all times and under all conditions.

The apparatus is extremely simple in construction and operates with maximum efciency and may be utilized in many elds of activity for counting articles whenever and wherever such a result is desired. The apparatus is particularly adapted for efficiently counting articles of uneven or irregular contour as exemplified for instance by the bags or sacks of merchandise A.

The apparatus furthermore is not restricted to counting successive articles of corresponding type and may be used, with equal efciency, for counting successive articles which differ from each other in physical character or form.

Various changes in the specific forms shown and described may be made within the 'scope of the claims without departing from the spirit of the invention.
