CONVEYER Appunti mea remargfia, 192s. seran n. :,soe.

My invention relates to conveyers comprising endless conveyer means, and 1t has for its general ob'ect provide a con'- strution of thisI c aracter comprising an- 1mproved andvnovel construction-of means for supporting yinter-mediate portions of the conve er. j

It 1s also an object ofi the invention to provide a conveyer having an improved and novel construction of means at intervals for supporting the loads adapted to be transported by the conveyer from one point to another. p I

Another object of the invention is to provide a conveyer of novelnconstruction, 1n-

cluding means whereby the durability of the conveyer is increased.

Another object of the invention is to rovide a construction of conveyer in w ich -1n a manner to produce a construction of great elliciency.

Other objects and advantages of the invention will be pointed out in the detail description thereof 'which follows, or will be apparent from such description.

In order that the invention may read` ily understood and its practical advantages fully appreciated, reference may be had to drawings, 1n which I have illustrated certain forms of. convenient embodiments thereof. However, it will be understood that changes in the details of construction may be made within the scope of the claims without departing from the inl, o Ol;

Fi 2 1s a view taken on the line 2--2/ vention.

-In the drawings,-

Fig. 1 is a view in transverse section of a conveyer structure embodying the invenof Fig. 1;

Fig. 3 is a perspective view showing a detail of the structure;

Fig. 4-is a view in side elevation of a portion of the structure, and in which an object which is being transported thereby is indicated in dash and dot lines;

Fig. 5 is atransverse sectional view Vshowing a modified construction of conveyer portion of the structure showing a detail of construction inv Fig.l 8 is a perspective view of an element ofthe construction; and

Fig; 9, is a view in side elevation of a portion of the conveyor structure shown in Fi 5.

Re erring to the drawings, it will be noted that the frame structure of the apparatus comprises cross-wise extending members 1 arranged at intervals. These members in the construction as illustrated consist of angle plates, but it will be understood that other shapes may be employed. Posts or `standards 2 of angle members, or members of other shapes, are secured at their lower ends by means of rivets 3 to the opposite ends of the cross-wise extending members 1 and extend upwardly therefrom. These are connectedintermediate their ends by cross-wise extending bars 4 of channel shape, but bars of any other shape in cross section may be emplo' ed. The upright posts or standards 2, w ich are located at intervals on opposite sides of the structure, are also connected by longitudinally extendplates 5.

llteferrin now to Figs. 1 to 4, inclusive, it will be ogserved that angle members 6 and 7 are secured by means of rivets 8 to the upper ends of the posts or standards 2, and that the said angle members extend lon tudinally of the structure at substantia ly right angles to the cross members 1 and 4; One flange of each of the angle members 6 and 7 occupies a vertical position, the flange 7 overlying the flange 6. The other flange of each of the said members extends inwardly as indicated' at' 9 and 10. These flanges are spaced from each other, as indicated in Fig. 1 of the drawings. The flange 10 of each angle is provided with notches or openings 12 at intervals for a purpose to .be hereinafter referred to. In addition to the angle members 6 and 7, angle members 15 are secured to the tops -of the posts or standards 2 with the horizontal flanges 16 thereof in the same plane as the horizontal flanges 9 of the angle plate 7. The flanges 16 and 9 operate to form a platform structure at the opposite sides of the conveyer structure. The vertical flanges 17 of the angle members 15 constitute and form outer sides of the platform formed by the horizontally extending flanges 9 and 16.

Conveyer chains 20'1ocated at the opposite sides of the structure are driven or operated by any suitable means (not shown).

tra

The upper portions or sections of these chains occupy ositions between the inward ly ext/ending anges 9 and l0. Shafts 22 are supported at intervals upon these chains.

' secured thereto nearthe opposite ends there of in adjacent relation to the inner members of the bearings 23. Nuts 29 upon the opposits ends of the shafts engage the outer members of the bearings so that the members 23 of said bearings are clamped between nuts 29 and collars 27. It will be seen that in this way each of the shafts 22 is connected with the conveyer chains at the opposite sides of the structure, and that thereby the said chains are bound rtogether to form a unitary conveyer structure.

Cylindrical load supporting members 30 are mounted upon the shafts 22. ln the construction as shown these load supporting members 30 are tubular or hollowT for the sake of lightness, but it will be understood that, if preferred, these cylindrical members may be solid.. The upper portions or sec tions of the chains 20 are supported upon-tho supporting rollers 3l mounted near the opposite ends of shafts 32 The rollers 3l are rotatable upon the shafts 82, or, if preferred, the shafts themselves may be rotatably mounted in their bearings. llhe rollers 3l are held in place upon the shafts 32 by means of collars 33 mounted upon the opposite end portions of the shafts in spaced re lation toeach other.

The opposite ends of certain of the shafts 32 are supported in the upright posts or standards 2, while others thereof are supported in brackets 35 which are secured to and depend from the upright flanges of the angle members 6 and 7. The rollers 3l project upwardly through the openings l2 in the horizontal flanges of the angle members 6 so that the upper horizontal portions or sections of the conveyer chains are adapted to be supported thereby. Said portions are also supported upon the upper sides of the horizontal portions l0 of the angle meme bers For supporting the lower horizontal portions of the conveyer chains l have provided traclas 40 supported upon the upper edges ci' the cross bars l.V The cylindrical load su .ng members 30 rest upon the upper edges of these tracks and inenten chains 20 are supported upon the rollers 31,

the-said shafts and load supporting means do not rotate, but when in the oppos1te position, with the load supporting means 30 resting upon the tracks 40, rotation of said load supporting means and the shafts 22 is effected. Suchrotation facilitates the linear traveling movement of the conveyer chains the shafts 22 are rotat- I and reduces the friction, which is necessary to be overcome by the power means by which the chains are driven.

'lhe load 4l, shown in dash and dot lines in Fig. llof the drawings, is supported upon a plurality of adjacent load supporting i members 30 and may be transported thereby from one position to another.

Referring now to Figs. 5 to 9,' inclusive, of the drawings, it will be noted that'the upper ends of the posts or standards 2 are connected together by the vertical flanges 44 of the longitudinally extending angle members 45. The horizontal flanges 46 extend inwardly and overlie the upper portions or sections of the chains 20. Channel bars 47 extend between the chains 20a. The flanges of said channel bars extend outwardly, as indicated :fn Figs. 5 and 6 of the drawings, and the op osite ends thereof, which are reduced as indicated at 48, extend through alternate links of the donveyer chains. The inner sides of the links through which the opposite ends of the channel members 47 extend Contact with shoulders 50. Retaining filler blocks 5l are secured by rivets 52 to the.

opposite ends ofthe channel members between the flanges thereof. rlhe inner ends of these filler blocks are provided with outwardly extending projections53, which contact with the outer sides of the links of the chain through which the opposite endsof the channel members extend. Each of the channel members 47 is provided with upwardly extending angularv supporting members 55. 'lhese supporting members are secured to the flanges of the angle members and are arranged in couples near the opposite ends of the channel members. At their upper ends these angular supporting members are provided respectively with outwardly extending portions 56, to which the load supporting platforms 57 are `'secured by rivets 58. rlhese load supporting platforms extend transversely of the structure with their opposite ends located in adjacent relau tion to the inner edges of the horizontal anges 46 of the angle members 45. The

wheels 31 mounted upon shafts 32, certain of which are supported at their opposite ends in oppositely disposed posts or standards 2, while others thereof are supported in depending bracket plates 35a. These depending bracket plates 358 are secured at 1ntervals to the vertical flanges 44 of the angle members 45.

'Ihe lower portions or sections ofthe conveyer chains 20a are supported upon rollers or wheels 61 rotatably mounted near the opposite ends of shafts 62, supported at their opposite ends in the longitudinally extending plates 5. The wheels 61 are retained in place by means of the collars 63, located upon the opposite sides-thereof, and secured to the shafts 62l Instead of the rollersv or wheels 61 being rotatably mounted on the shafts 62, they may be rigidly secured thereto, in which case the shafts 62 should be rotatably mounted upon the supporting plates 5. If preferred, not only may the shafts 62 be rotatably mounted, but the rollers or wheels 61 may also be rotatably mounted upon the said shafts. 1

Secured at intervals to the vertical flanges 44 of the angle members 45 are angle clips or brackets 64, upon which the horizontal flanges 65 of angle members 66 are supported. The vertical flanges 67 of these angle members constitute guards for the platform formed by the horizontal flanges 46 and 65.

The conveyer chains 20a may be driven by any suitable power means (not shown).

The conveyer structures as illustrated and described are designed primarily for transporting molds employed in connection with provided a simple and durable construction by the employment of conveyer apparatus,

be transported most of which objects may `eiiciently and conveniently from one point to another.

Having thus described my invention, what I 4claim and desire to secure by Letters Patent is:

1. In conveyer apparatus, of flexible endless conveyer means located in parallel spaced relation to each other, rotatable bars extending transversely of and conneeted at their opposite ends to the said conveyer means,which bars areadapted to support loads to be transported by the said 'conveyer means, combined stationary and rotatable supporting means for supporting the upper portions of the said flexible conveyers, and means for supporting the said load supportingl means and the said conveyer means w en the latter occupy their lower position. v 4

2. In conveyer apparatus, the combination of endless conveyer chains, stationary means located underneath the upper portions of the said conveyer chains for supporting the same, rotatable supplemental supporting means located at intervals underneath the upper portions of said conveyer chains and projecting slightl above the planes of the upper surfaces o the said stationary supporting means, means for supporting the lower portions of said conveyer chains, and load supporting means and extending transversely of said conveyer chains and the respective means bein connected at their opposite ends to an supported by the said chains, substantially as described.
