ROLL SUPPORT FOR STRAP CONVEYERS Filed May 28, 1938 3 Sheets-Sheet 3 A U/ H11/UWM INVENTOR A. PLAUSICS ORW@ 20 at substantially any point between the ex tremity thereof and its mid-portion. The shaft and eyebar are securely positioned in relation to one another by means of a set screw 2|. Adjacent the end of the shaft 2| is a cotter pin 22 which acts as a stop, thereby preventing the shaft from sliding endwise out of the eyebar II. It should be noted that the eyebar or extensible arm II is also provided with a pin 23 for a similar purpose.

The pulley or roller 24 is positioned on the shaft 20 at any desired point intermediate the extremities thereof. Endwise motionof the pulley 24 on the shaft 20 is'impeded by suitable collars 25 which may be securely aiilxed to the shaft 20 in any conventional manner.

The other end of the shaft 20 is supported in a similar manner. In this connection it is seen that the arm 26 may occupy a quite different po'- sition in relation to itsassociated sleeve 2'I. Also it may be seen, particularly in Figs. 2 and 3, that the clamp 28 may be attached tothe pipe structure I Il at a different height than the clamp II. Thus, it is apparent that by the novel instrumentalities comprising this invention a pulley which is mounted on a shaft may be adjusted so that it is angularly disposed in three dimensions relative to the supporting structure.

Fig. 3 indicates the manner in which a pulley mounted by means of the present invention may be incorporated in a Istrap conveyer. In this particular illustration a conveyer of the twist lor double strap type is shown, comprising the belts or straps 29 and 3B which are arranged in contact with one another and between which is gripped a telegram 3 I'. Obviously, such a pulley may also be used with equal facility in other typesV of strap conveyors such as the so-called drag conveyer.

Having reference now to Figs. 4, 5 and 6, there is depicted a modified form of a shaft mounting. It is substantially similar to the embodiment hereinbefore described vexcept for the configurationv of the eyebar 32. The opening throughthe ringed portion of this member i-s of an elongated nature and, in the preferred form here shown, is elliptical in shape. Such an opening or hole may be constructed either bymilling or, more simply, by rocking a. drill backward and forward through any desired angle. By providing such an opening in the arm 32 it is possible to attain a greater degree of angularity in mounting the shaft 20. It will be noted in connectiony with these figures that the arms 32 and 34 are arranged so that they are pointed in opposite directions and that the clamp 36 is not provided with a lug. It will be appreciated that such an arrangement is susceptible of a verywide variety of adjustments. A

Figs. 5 and 6 show the shaft mounted horizontally although, obviously, this embodiment may also be arranged to mount the shaft and pulley at a substantial angle with the horizontal.

vIn most conveyer systems now in use the structure or framework which is employed to support the direction-changing pfulleysand otherapparatus comprises one or more of the more common structural steel shapes. such as angles, channels, I sections, etc. Fig. 7 shows, in transverse section, a portion of such a framework made up of one of the aforementioned sections which in the gure is illustrated asjan angle 3 1. An angular bracket 38 which may have anydesired configuration, is fastened to thefframework 3IY by means of the bolt 39. The-,outwardly extending Vportion of this bracket is'provided with a hole which plurality of angular serves to mount the stud I4. This type of mounting will generally be utilized with an eyebar of the type illustrated in Figs. 4, 5 and 6. The use of such a bar 32 will permit of a substantial adjustment of the pulley shaft. Obviously such a device will not lend itself to such a wide range of adjustments as will those previously described. However, by utilizing some of the novel instrumentalitiescomprising this invention, a substantial increase in the range of adjustment over that obtainable with the prior art devices may be effected.

In Fig. 8 there is illustrated a typical twisted strap conveyer system. It comprises two endless straps or belts 40 and 4I which are arranged with a system of pulleys in any well known manner.

The belts derive their movement from a motor 42 .and are arranged to form a medium of conveying/,light sheet material T from point A to point B. ft'will be noted that these points are disposed generally diagonally with reference to the room in which the conveyer is located. A typical use of the adjustable pulley mounting as shown in this figure illustrates the ease with which Asuch a system may be installed on supporting structures which are disposed squarely with reference to the sides of the room. Pulleys 43, 44, and 45 are mounted on a supporting framework 46 which is suspended from the ceiling. Itmay be clearly seen that by the suitable manipulation of the improved type of pulley mounting, the necessary degree of angularity of these pulleys with respect to their supporting framework may be obtained. It will be apparent that, if at some future'date it is desired to rearrange the system here shown so that the conveying route will connect points A and C, for example, the only necessary changes to be made are the adjustments of the pulleys 43, 44 and 45 and such incidental changes as altering the lengths of the belts, etc.

Obviously this invention is not limited, in strap conveyers, to the mounting of direction changing pulleys, but may also b e used to mount pulleys which provide support to a strap conveyer at some point intermediate the direction changing pulleys. It may also be used in conveyers of this type where pulleys are needed for corrective purposes, that is wherever there is a tendency for one of the belts to diverge laterally from the other. Obviously various modifications of this invention may be made Vwithout departing from the spirit thereof.

The nature and operation of the invention may be ascertained from the foregoing description and .it is `particularly defined in the following claims. Itis to be understood that the scope of the invention shall be determined only by the prior art and by thev express limitations of the appended claims. What is claimed is:
