Application led July 9, 1926. Serial No. 121,327.
the work-so that there is a minimum ofy lateral displacement either longitudinally or transversely of the direction of travel of the conveyer. It is also desirableto provide the conveyer with a surface which will 1g have a slight yielding action tending to force the work Ainto engagement with the drums. Rubber, in various forms has been used for this purpose, but heretofore ditlicult has been encountered in providing a' ,n sur ace of rubber which would serve the purpose and at the same time would vnot entail great expense in replacement or reair if the surface became torn or damaged.
It is the general object of this invention to z5 provide a new and improved pad for a conveyer adapted to be one of a number of such pads which constitute the surface of the conveyer and which may be readily and easily replaced if dama ed.
3o `Another object of this invention `is to provide anim roved conveyer pad which may be manu actured at a low cost, is readily replaceable, and is eiiicient in operation.
85 Another object is to provide an improved surface for a conveyer which comprises a plurality of separate 'pads removably secured to the base of the conveyer.
' A further object is to roduce a conveyer in which the contact sur ace is com d of a plurality of right and left hand padspconstructed to provide a definite pattern or tread.
Another Objectis to provide a conveyer '.5 pad which has a regular shape so that the pads may be each other.
Another object is to produce a conveyer pad which has a resilient surface formed to provide a series .of members which are adapted to contact the work.
Other objects and advantages will be apparent from the following description and the accompanying drawings, in which:
Fig. l is a fragmentary plan view of a I conveyer illustratingl the improved form of the invention.
Fig. 2 is a vsection taken on the line 2 2 of Fig. 1.
Fig. Sis a section taken on the line 3-3 of Fig. 1.
Fig. 4 is an enlarged plan view of the preferred form of the invention.
5 is a section taken on the line 5--5 of Fig. 4.
While I have shown in the drawings and will hereinafter disclose in detail the preferred embodiment of the invention, it is contemplated that various changes in construction and arrangement may be madey by those skilled in the art without departing from the spirit and scope of the invention Aas expressed in the appended claims.
' In the type of conveyer contemplated by this invention, a travelinor bed is adapted to receive a plurality of indlvidual pads which provide the bearing or contact surface of the conveyer. The travelin bed comprises the usual pair of heavy end ess chains having links 10 to each of which a cross bar 12 is secured, as by means of bolts 11. The chain may be of any construction suitable to that particular type of machine in which the conveyer is to be used, while cross bars l2 are preferably formed of sufficiently heavy steel to prevent any possibility of their springing intermediate the two chains.
The pad 13 in its preferred form (Figs. 4 and 5) comprises a suitably heavy metal base 14 provided with a resilient surface 15 placed in abutting relation to on one side thereof. The flexible surface is usuall formed of rubber which is moulded on an vulcanized to the metal base 14. In order firmly to secure the rubber surface to the base 14a plurality of openings 16 are provided in the base, said openings being countersunk from the under side of the base as lshown in Fig. 5.. Thus when the rubber surface 15 is moulded on the base 14 the rubber will enter the openings 16 and provide a wedge shaped foundation which upon vulcanization will resist any force tending to pull, tear or shear the, rubber surface from the base.
An important part of this invention is the form of the contact surface of' the pad and the pattern or tread which is formed by these pads when they are secured to the bars 12. The pad 13 is preferably in the form of a parallelogram and the contact or bearing surface of each pad, after moulding, presents a series of alternating ridges 17 and grooves 18, said ridges and grooves running parall'el to one side of the pad. Each pad is secured on the bar 12, as by means of headed bolts 19 threaded into holes in the bars 20 through apertures in the rubber surface and countersunk openings 21 in the base 14 of the pad, in such position that the ridges 17 and grooves 18 will be at an angle with the edges of the bars 12. v
Inasmuch as a transverse creeping motion would be imparted to the Work if the ridges 17 on every ad were to run in the same direction,- rig t and left hand pads have been provided.v That is to say, the pads are similar in eneral shape and contour but are reversely ormed so that if the backs of a right hand and a left hand pad are placed together themargins of the pads w11l coincide. These right and left hand pads are secured upon the alternating bars of the conveyer, that is, the right hand pads are fastened to every other bar and the left hand pads are rigid with the intervening bars. In this vmanner anirregular zig-zag tread is formed on the contact surface of the conve er.
t is, of course, obvious that the ridges may run in an unbroken line, but it has been found preferable to stagger the ridges and the wor when the pads are properly secured on the bars 12, the ends of the ridges 17 on the pads on one bar will be o osite the grooves 18 on the pads on the a jacent bar. As the right and left hand pads are the same size the proper positioning of the pads on the bars to obtam'the' staggered relation is a simple matter of predetermining the position of the bolt holes 20 in the bars 12. l
Due to the non-rectangular shape of the i padst13, spaces, each in the shape of a trapezoid, will be left at each end of the bars 12. These spaces may be covered by specially (grooves on adjacent bars., In other As shown plainlyin Figs. 2 and 3, it will be impossible for any metallic part to'contact or bear against the work until after the tread has rbeen almost entirely worn away. Injury to the work can thus be avoided, since the worn pads can be replaced before the tread is entirely Worn away.
Furthermore, a conveyer has beendevised which has a resilient bearing surface Aand which, due to the design of the tread, will resist any tendency of the work to creep.
I claim as my invention:
1. A conveyer pad, comprising, in combination, a parallelogrammic base having a plurality of openings therein, a resilient surface on one side of said base, having parts thereof entering said openings to anchor said surface on said base, and a plurality of ridges on said surface extendin substantially parallelto one side thereo 2. A conveyer having in combination, supporting means, similarly shaped but reversely formed replaceable pads arranged on said supporting means to provide a surface for said conveyer, each of said pads comprising a base having a resilient surface, said surfaces having a plurality of ridges thereon at an angle to the direction of travel of said conveyer.
3. In a conveyer comprising, in combination, a traveling bed including a plurality of cross bars, a plurality of pads secured on each of said cross bars and arranged to provide a continuous contact surface for said conveyer, said surface of each of said pads being formed of a resilient material having a plurality of ridges thereon extending at an angle to the direction of travel of said conveyer, the angles of said ridges on longitudinally adjacent pads being in oppo- Asurface including a series of ridges extending angularly thereacross, said right hand pads being secured to alternate bars and said' left hand pads being secured to the intermediate bars in such position that the ridges provide a zig-zag tread for the conveyor.
5. A conveyor having, in combination, a traveling bed including a, plurality of cross members, a plurality of pads secured to a1- ternate members, and a. plurality of similarv 5 but reversely shaped pads secured to the intermediate members, the surfaces of said pads being formed with ridges, said pads being positioned on said bars so that the ridges on one group of pads will be staggered in m relation to the ridges on the group of pads on the adjacent bars.
In testimony whereof I have hereunto aiixed my signature.
