SPECIFICATION forming part of Letters Patent No. 781,614, dated January 31, 1905. Application filed February 25, 1903. Serial No. 145,055.

To all [I'l 0111. it may cmtccr/t:

Be it known that l, \VILLIAM L. MOCABE, a

citizen of the United. States, residing at Seattle, in the county of King and State of \Vashmgton, have invented certain new and useful improvements in Portable Endless Conveyors;

and I do herebfv declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in portable endless eonveyers, and particularly to adjustable devices therefor for the handling of articles of various sizes.

The object in view is the provision of means for conveying articles and preventing their receiving shocks or jars during transit.

A further object of the invention is the provision of means for adjusting the parts for accmnmodating packages of different widths and thicknesses.

With this and other objects in view the invention consists, in combination with asuitable framework, of a longitudinally-arranged platform pivotally mounted at one end and means for raising said platform relative to the framework.

lt also consists, in combination with a suitable conveyer,of a driving-wheel there forcomprising sections, means for supplying power to one of the sections of the wheel, and cushions for imparting motion from said section to the other section thereof.

it further consists in certain other novel constructions. combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

in the accompanying drawings, Figure 1 represents a view in side elevation of a portion of a conveyer embodying the features of the present invention. Fig. 2 represents a view in side elevation of the remaining portion thereof. Figs. 3 and 4: represent top plan views of the portions of the conveyer shown in Figs. 1 and 2, respectively. Fig. 5 represents an enlarged transverse sectional view taken on the plane of line 5 5 of Fig. 1. parts being shown in elevation. Fig. 6 represents an enlarged view, in side elevation, of the discharge end of the conveyor, parts being broken away. Fig. 7 represents an enlarged detail view, in side elevation, of the power-transmitting pulley or wheel, parts being broken away. Fig. 8 represents an enlarged detail fragmentary view, in transverse section, on line 8 8 of Fig. 7. Fig. 9 represents an enlarged detail view, partially in section, of oneof the guiderail-supporting brackets. Fig. 10 represents an enlarged detail fragmentary sectional view through one of the balls and conveyor-bars. Fig. 11 represents a sectional viewon the plane of line 11 11 of Fig. 10.

in the present art it has been found desirable to provide, in combination with a conveyer framework, means for guiding and retaining an article being conveyed, and during the transit l iind that in the conveyance of easily-breakable articles it is desirable to provide means for preventing the same being jarred or roughly shaken, and in order to accomplish this, together with other benelicial results, I employ the elements disclosed in the accompanying drawings, in which 1 1 represent the side frames of a conveyorframework connected together by any suitable transverse bars 2, each of said side frames comprising upper and lower rails 3 and 4, connected by any suitable struts and at in-. tervals by diagonal braces 5 and 6, spaced apart and connected together by a suitable web or cam-plate 7, formed with a segmental slot 8 for purposes hereinafter mentioned. Any number of the slottedwebs may be employed and are arranged in pairs --that is, each web on one of the side frames 1 has a corresponding web arranged on the opposite side frame.

The conveying-belt consists of endless cables 9 9. traveling at each side of the framework and passing over pulleys 10 14), arranged at the receiving end of the conveyer and mounted upon a common shaft 11, extending across the framework and finding bearings in a suitable bearing-box 12 at each end, mounted to slide in suitable longitudinally-arranged guides 13 and provided with adjusting mechanism H, of any preferred type, whereby the pulleys 10 maybe moved bodily longitudinally of the framework for governing the tension of the conveyor-belt. Each of the pulleys is grooved circumferential] y on its pe- I riphery for the reception of its respective ca' 1 ble 9 and is provided with a series of notches 15, spaced apart on its periphery and adapted to receive metallic balls 16, arranged at intervals along the length of the respective cables 9, such balls being spaced apart a distance equal to the distance on the periphery of the respective pulleys 10 between the notches 15, so that each of the said pulleys acts as a sprocket. Extending transversely of the framework and connecting the respective cables 9 and spaced apart any suitable distance are conveyer cross-bars 17 17 which engage the respective cables 9 ata distance from the preceding and succeeding balls 16 thereof equal to the distance between two of said balls, the diameter of each of the bars 17 being approximately the same as that of one of the balls 16, whereby the projecting ends of said bars fit within the notches 15. By reference to Figs. 10 and 11 the manner of connecting the ends of the bars 17 to the cables 9 will be observed, which consists in overlapping the ends of the sections of cables 9 within a ball 16, passing a bolt 16 through said ball and through the sections of cable and preferably filling the space within the ball with Babbitt metal, said ball 16 being hollow. The end of the bar 17 is longitudinally notched at diametrically opposite points, as at 17 and the cables 9 passed through said notches, with the ball 16 positioned within said bar 17, the bar 17 being hollow and of sufficient diameter for snugly inclosing the ball 16. Each of the balls 16 is constructed and secured to the respective cables 9 exactly similarly to the construction and attachment of balls 16, the only difference being that of diameter, the balls 16 being substantially of the same diameter as the bar 17.

The conveyer-belt of the present device consists of the cables 9 and cross-bars 17 and mounted between the carrier and return portion thereof within the framework is an adjustable platform 18, composed, preferably, of slats suitably secured together and extending throughout the length of the conveyer. Each side of the platform 18 is provided with a plurality of guidingetravelers 19, extending through the respective slots 8. The said platform 18 at the discharge end of the conveyer is hinged to a suitable segment 20, loosely carried by a rotatably-mounted shaft 21, such shaft also carrying pulleys 22, which are fixed thereto, one being spaced from each end of the segment 20, the pulleys 22 being constructed and operating exactly like pulleys 10. Near the receiving end of the conveyer is arranged a transversely-mounted rotary shaft 23, provided with a ratchet-wheel 24 at each ,end or only at one end, as may be desired, and a drum 25 at each end, a suitable detent 26 engaging the ratchet 24. A

cable 27 extends upwardly from each drum 1 25 about a pulley 28 and along the conveyer a short distance and is fixed, as at 29, to the platform 18. A crank or other operating mechanism 30 engages the shaft 23 for purposes of rotation, whereby the cables 27 may be taken up or paid out, and as such cables are taken up the platform 18 is drawn forwardly and upwardly, so that its travelers 19 move in slots 8, guiding and steadying said platform, and the segment 20 swings upon the shaft 21, such segment being rotatabl y mounted thereon.

The shaft 21 projects through the side frames 1 and is formed with a bearing in each of said side frames, which is composed of a plate 31, secured to supporting-bars 32 32 and carrying a ring 33 upon each side thereof and each formed with an internal concave surface 34, registering with a suitable aperture formed in the plate 31, whereby a partially-spherical bearing is provided for a ball 35, which ball is bored for the reception of the journal of shaft 21. The ball 35 may be provided with circumferential grooves 36 36 for reducing the weight of the same or may be made solid, as desired. By this arrangement it will be observed that with a thin plate connected to one of the side frames a comparatively wide hearing may be formed and the shaft 21 may be rotated within the balls 35 without excessive wear, whereby a minimum of weight is necessitated, and yet suflicient strength is obtained for all practical purposes. On each of the projecting ends of shaft 21 is mounted a gear-wheel 37, meshing with a pinion 38, the pinion 38 being mounted upon the projecting ends of a shaft 39, arranged transversely of the framework and extending beyond the side frames in a parallel plane to the shaft 21, a driving-drum 40 being mounted centrally upon the shaft 38 and receiving power through any suitable belting 41 from a pulley carried by a counter-shaft 42, suitably arranged in the framework, said shaft in operation receiving its power from a suitably-arranged dynamo 43, also mounted in the framework. Of course other power-supply means may be employed without departing in the least from the present invention.

During the travel of the bars 17 throughout the length of the framework the cables 9 ordinarily might sag sufficiently for permitting such bars to drop out of operative position, and to overcome this difficulty 1 provide longitudinal rails, preferably angle-bars 44, extending beneath the plane of travel of the ends of said bars 17, whereby if the cables sag and the bars are permitted to drop they will be limited against contact with platform 18 and held against too greatlowering and will have their ends supported by the said bars 44.

Arranged at suitable intervals on each of the rails 3 are inwardly-projecting brackets 45 45, the outer end of each of said brackets being bored transversely, as at 45, for receiv- LII ing and retaining bolt s6, as best seen in Fig. 3). said bolt passing through the end of the bracket and being threaded at its upper end into a retaining-nut M. The nut T7 is ordinarily provided with an operating-handle i8 for facilitating its rotation. Although Ihave illustrated a threaded bolt with the nut 4:7 threaded onto the same, it will of course be seen that a cam may be substituted for the nut -LT as may be desired. The under portion of the outer end of bracket is serrated, as at 9, for engagingserrations in a plate 51, secured onto the respective rail3. The said serl rations normally lock the brackets 15 against lateral movement: but a spring 52 is mounted within the bOIOdS and coiled about the bolt to. with its lower end resting upon plate 51 and its upper end engaging an annular shoulder 53,partially closingsaid bore, whereby a tendency is given to the bracket *5 to lift for releasing the engagement of serrations a9 and 5 The nut T7 normally prevents such disengagement; but when desired said nut may be rotated by means of handle %8 and the bracket 5 thereby be left free to swing laterally. The inner end of bracket 45 is apertured suitably for receiving a pintle 5i, carried by a guard-rail 55, extending throughout the length of the respective side frame 1 and serving in operation to prevent lateral displacement of the articles being conveyed.

l have disclosed two driving-gears 37, which two are employed for evenness of movement; but of course a single gear may be employed withoutdeviation from the invention. Each of the gears 1:57 is composed of an inner section 37 and an outer section 37. The inner section consists of a suitable ring carried by spokes or a web fixed to shaft 21, and the said ring provided at intervals with radially-projecting lugs 3T 37". The outer section 37" consists of a ring surrounding the section 37 and provided on its outer surface with gearteeth Bihwhich mesh with the respective pinion 36. Extending inwardly from the inner surface of the section 37" are suitable lugs 3T 3T. spaced apart approximately the same distance as the distance between the lugs 37". The lug 07" project beyond the plane of the lugs 37, so that said lugs overlap, and a spring 37 or other suitable cushion is interposed between each of the lugs 37 and 37 in the direction of movement of the shaft 21, as indicated by the direction of the arrow in Fig. 7. During operation the pinions 38,1neshing with the teeth 37, rotatethe section 37", whereby the springs or cushions 37" are pressed against the lugs 37 and drive forward the inner section 37, and with it the shaft 21, whereby the pulleys 22 are rotated for driving the carrierbelt. Of course means must be provided for preventing lateral displacement of the section 37 relative to section 37, and in order to i keep said sections in line I secure a flange 37 onto or formed integral with each side of the l ring of section 37", such flanges extending beyond annular shoulders 37" 37 on the section 37, a housing being thus formed for the springs or cushions 37 A discharge-platform 56 is supported at the discharge end of the conveyor by a transversely-mounted rod 57, extending through bearings 58, formed on the side frames 1, said rod being bent and havingits ends projecting in parallel planes parallel to the conveyor. A suitable weight 59 is adjustably mounted on each end of said rod 57, and the rod being fixed to the platform 56 is designed to support the same in any given or desired angle by an adjustment of the weights 5%) longitudinally of the parallel portions of said rod 57.

In operation the carrier-belt is driven as described and the articles to be conveyed are placed on the platform lb, which platform has previously been positioned at the desired distance vertically t'rom the cross-bars 17, so that such cross-bars engage the articles on the said platform and convey them to the discharge end of the conveyor. If comparatively wide packages are being conveyed, the brackets 45 are swung outwardly for moving the guiderails as far apart as may be desired, and if comparatively narrow packages are being con veyed the said brackets are swung inwardly. so that the guide-rails are brought sufliciently close together for preventing the lateral displacement of such packages. As the package to be conveyed is deposited on the platform 18 one of the cross-lmrs l7 approaches and comes in contact with the same with necessarily more or less of a jar; but such contact is cushioned by the action of the springs 37", such springs giving for any sudden retardation in the movement of the conveyor-belt and preventing any pronounced shocks being given to the packages being conveyed, whereby even the most delicate articles may be transferred by my improved conveyor without danger of breaking. Upon reaching the discharge end of the conveyor the package is automatically deposited from the platform 18 onto the platform 56, which is poised in air, being balanced in the position desired by means of weights 55), and upon receiving a package from the conveyor automatically lowers into contact with any support beneath it in position for the discharge of the package which has just been delivered. The weights 59 are usually positioned for resisting a given amount of pressure on the platform 50, whereby when a package isdeposited thereon it gently lowered without danger of injury.

Although I have set forth in detail the particular features of a complete operative structure, yet it will be understood that I may deviate therefrom with respect to size, shape, and minor elements without departing iu the least from the spirit and scope of the present invention.

I am not claiming under the present application the specific construction of cushioned driving-gear and the particular bearing disclosed, but propose to reserve the same as the subject-matter of separate and independent applications, the right of divisional application being hereby expressly reserved.
