Original application filed January 8, 1921, Serial No. 435,827. Divided and this application iiled crater 1e, '1923, serial No. ceases. Renewed :rune 7, 1927. i

This invention relates to a conveying member, the present appllcationubemg. a division of my prior apphcation Machine January 8, 1921, patented January 22, 1924, No. 1,481,347.

It is an object of the 1nvent1on to provide a conveying member Wh1ch may be utilized in connection withany desirable association of mechanism, such as, for example, that illustrated in the application previously referred to, and which is particularly adapted for use in connection with the conveying or feeding of strips of material such as, for example, paper. i

It is a further object of the invention to provide a conveying, device which may bej operated at any desirable speed and =by means of which the material being fed will Y and which Will also be economical and readi-4 be efficiently retained in engagement therewith.

A still further object is to be predicated to' the provision of an article of the nature stated, which, although efficiently engaging the material being fed under all conditions, Will not in any'wise injure the said material.

Another object to be predicated to this in vention is thatof furnishing a conveying device Which is particularly adapted for use in the conveying or feeding of a strip orV webof moist material such as would be the case if a coating of adhesive were applied to one of the face-s of the material. p

Still another object is that of constructing a conveying device which is preferably to .be utilized for the purpose of feeding a strip of material and Which,in suoli usc,rvill serve to positively' move the fed strip.

An additional object is that of providing a conveying device Which Willeiiciently' perform the purposes for which it is intended ly manufactured.` `@ther objects of the invention will in part be obvious and Will in part appear hereinH after. l The invention accordingly comprises the features of construction combination-of elements, and arrangement of parts, which Will be exemplified in the construction hereinafter' set forth and the scope of the application of Which Willvbe indicated in the claims.

For a fuller understanding-of the nature and objects of the invention reference should be had to the following detailed description taken in connection with the accompanying f drawing, in which:

. for making boxes, Serial No. 435,827, filed the present invention, and showing the same connected with one form of apparatus which may be utilized for operating the same,

Fig. 2 isv a side elevation of the device constructed in Fig. 1,

Fig. 3 is an enlarged transverse sectional View of the conveying device,

Figs.. 4 and 5 are sectional side views taken along the line and inthe direction of the arrows indicated at 4-4 and 5--5 respectively, in Fig. 3, and

Fig. 6 represents a detail of the periphery of the said conveying device'.

In the present embodiment lone of the preferred forms of the invention has been shown, and this includes a conveying device in the nature of a feeding Wheel which is formed with ports selectively! lconnectible with an air exhaust so that a strip which is in contact with the Wheel adjacent these ports will be retained in this engagement.

Thus, reference being had particularly to Figs. 3, 4, 5 and 6, inclusive, it will be noted that the reference numeral 10 indicates a feeding Wheel which, in the present embodi ment, is particularly (adapted. for use in connection with the conveying of strips and this Wheel preferably has its periphery'recessed, as at 11, to form what might be termed a track for the laccommodation of the strip to be fed. Also it Will be observed that a yseries of crclnnferentially related openings 12, arc formed in the baseportionof the track and these openings each4 communicate with one of an annular series of ports 13 in the present instance formed in the side face or hubv of the wheel 10. This communication may be established by means of a number of independent conduits -14 each having one of their ends in communication with one of the openings 12, the opposite end of each of tlie conduits being connected with one of the ports 13.

The Wheel 10 may be keyed, as at 15, to a shaft 16 'and the latter is mounted for rotation in a suitable bracket 17. A plate 18 is disposed adjacent to that face of the Wheel orhub in which the ports 13 are formed, and this plate in the present exemplication having a radius vited in this connection to Fig. 6,- in which Aregistry others ofthe same will -pass into operative hausting means,

. `'hus, in these 'is rotatable relative to -the shaftd 16 and wheel 10, and is held against rotation with respect to the fixed parts of the mechanism -by means of an arm 19 forming a part of the bracket 17, any desirable form of connectrion being utilized at this point. In order to lhold the plate 18 inintimate'engagement with the face of the wheel last mentioned, it is preferred that an extension 20 be provided, forming a part of the wheel, and in the nature of a sleeve encircling the shaft 16c Mounted upon this extensionl and adjacent the end of the same is a retaining collar 21 and interposed between this collar and the outer spring 22.

With a view to connecting the openings 12 with a suitable air exhaust, it will be perceived that the plate 18 is formed in its inner face with a groove chamber 23, which is disposed in an arc equal to that of the circle. in whlch the series of ports 13 are disposed, and when the parts are in assembled position as, for example in Fig. 3, the chamber 23 communicates with certain of these ports. One end of this chamber is connected as, for example by a conduit 24, with a air exhaust openings'v 12 which communicate with ports in registry with the chamber 23 will have fluid drawn through them and inthe event that any article, such as a` strip, overlies the openings 12, this article will be gripped and maintained in intimate contact with the periphery of the wheel 10, attention being init will be noted that the openings 12 are preferably flared adjacent their Outer edges, as at 25, so as to engage the strip throughout approximately its entire width. If now the plate 18 and the wheel 10 are moved relative to each other, it will be understood that certain of the ports will move out of with the, air chamber 23, while connection therewith, and due to the factj in the present instance,

openings 12 will thus exert a pneumatic grip ing action in a predetermined station in t e path yof rotation of the wheel. In consequence, if a strip or other piece of material is fed over the wheel or by the same, this strip will be firmly gripped throughout a certain part of the path of travel of thel wheel and will be released upon arriving at aV predetermined station.

Now with a view to providing an air exas well as means serving to move the wheel 10 relative to the. plate 18, it will be perceived, reference being had to Figs. 1 and 2, that the same may be placed in any desirable association of mechanism; views the reference numeral face of the plate 18 is a providing an air suitable. and thus it is obvious that those susceptible to injury,

that, the plate 18` wardly) this being a is held stationary, it will be noted that thc` 7 26 indicates a motor which by means of a. suitable' drive 27, serves to`operate a vac'- uum pump 28, the latter being connected by a conduit 29 with a reservoir 30, which is in turn connected by a further conduit 3l with a conduit 24, and it will, of course,

be understood that a suitable valve 32 and gauge 33 be associated with this mechanism, in order to regulate the flow of the fluid, and to indicate .the degree of vacuum existing in the reservoirv 30 and associated conduits. he motor 26, by means of a further drive 34, may also serve to rotate a countershaft 35 which is connected in the present instance, by a belt 36 with a pulley 37, attached to the shaft 16.

If, for example, it is desired to feed a strip 38 to a mechanism where the same is to be operated on, and this strip is to have one of its .faces coated with adhesive, this may readily be accomplished by the use of a l conveying apparatus or device involving the by the wheel 10 and fed thereby to lthe mechanism 4for receiving the coated strip.

From'the foregoing it will be perceived, although the-strip is moist and t-hus very that in using a conveying or feeding device within the scope of the present invention, it is very unlikely that the strip will be torn or otherwise mutilated despite the fact that by the use of the present invention, the material is steadily and positively fed at virtually any rate of speed which may be desired. Also, it will be understood that the `device will not become obvjectionably coated with adhesive or other moisture, (due to the fact that the moist face of the strip preferably extends outdecided advantage over most mechanisms heretofore utilized -for feeding material of this nature, which mechanisms usually hesive or other moisture after the machine vhad been in operation for a short length of ime.

Thus it is obvious in operation, that among others the objects aforementioned are accomplished be modified in many particulars accordwith which it is to be utilized.

Since certain changes may be made in the above construction and different embodiments of the invention could be made withlll and it will be understood that the construction of the conveying device, i. e., the feed wheel and associated mechanism, may ing to the type of apparatus .in connection nl became coated with adv CTI out departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of.
