Y., a,corporation of. Massachu-r se Application August 126', 1931. Serial N9;j55914=8 Claims. -.(o1.--1 9.&+-'19m;
This-invention relates to improvements in the type of plate conveyer belt disclosed in an application filed by Vernon C. King on Aug. 26, 1931,
Serial No. 559,432, wherein adjoining longitudinal 5 sections are pivotally interconnected by double hinges and the links are formed with bearing supports to space the platesfrom the carrier drums. The present improvements are related particularly to the form of links employed to overcome certain disadvantages in practice found 7 to exist in the type of link illustrated in the said King application, all as will appear more fully hereinafter. Reference is now to be had to the accompanying drawings showing the improvements and also, by way of contrast, the King construction which offers certain objections. In the drawings: 7
Figure 1 is a view in section showing the relation of the improved conveyer and links to a carrier drum and taken on the plane indicated by the line 1 1 of Figure 2.
Figure 2 is a view in plan of a fragmentof the.
improved conveyer.
Figures 3 and 4 are illustrations in side elevationsomewhat diagrammatic, of types of links shown in'the King application.
7 Generally speaking, the improved conveyer includes longitudinally extending plates a, b, 0, each of theplates carrying at its ends hinge pins illustrated, respectively, at a, a b and c. The
plates are slotted as at a b and 0 respectively,
to receive links d which have horizontal slots d therethrough to receive the adjoining hinge pins (1, b anda 0', respectively. By the construction described it will be evident that a double hinge connection" is afforded between adjoining sections with all of the advantages pointed out in the said King application, Serial No. 559,432.
The general type of connection described is illustrated in Figures 3 and 4. As shown in those figures each link D has a. downwardly extending bearing portion D which engages the surfaceof the carrier drum e and spaces the plates therefrom sufiiciently to relieve the plate of bending stresses. In Figure 3 the section D issomewhat pointed at its lower end while in Figure tit is somewhat rounded. When the adjoining plates ,f are horizontally disposed the links D will conform so that the horizontal slot D therein will be substantially in alignment with adjoining plates.
When a plate passes onto the carrier drum e and travels thereon as indicated by the arrows, it will be pulled along by the preceding plate. The link D will remain with the slot D in substantial alignment with the preceding plate so that the oncomin plate will ha e wreck about i s h n e pin, such as g to conform to the change in direction depending on the radius of the drum. In other words, all angular movement between successive plates will take place about one hinge pin, that being the trailing hinge pin.
The present invention has for its principal object to provide a construction in which relative angular movement between adjoining plates will take place about the two adjoining hinge pins I whereby only one-half of the total angular movement will occur'about each hinge pin. Referring now to Figure 1 it will be seen that the link it has two downwardly extending bearing sections (1 d both of which are adapted to contact with the surface of the carrier drum F. It is preferred that these bearing sections (1 11 shall be spaced apart and shall'contact, with the surface of the drum on radii falling outside of the radii pass- 7 ing through the axes of the respective hinge pins b, a. Further, the contacting edges of the bearing sections d d may be convex with respect to the surface of thedrum. In the improved construction it will be evident that as each link it is drawn into contact with the surface of the drum its bearing sections d (P, will be pressed onto the surface and the adjoining hinge pins constrained to move along the same are. This necessarily results in each plate section having the same angular movement about its hinge pin. It will be found that of the included angle between adjoining sections one-halfof the angularity is accounted for by movement of one plate and onehalf of the angularity is accounted for by movement of the other plate. This reduces the wear on each pin and equalizes the wear on all pins. It requires less total angular movement of each plate about each pin and greater ease of movement and flexibility thereby reducing any tendency to bind. The bearing sections d ,'d of all of the links will be of such form and size as to best adapt them to their intended purpose which is, in addition to assuring the action described, spacing the plates from the surface of the drum so as to relieve them from bending stresses.
Changes in dimensions and form are tobe regarded within the scope of the'improvements described.
What I claim is:
1. In combination with a carrier drum, a plate belt conveyer, links hingedly connecting adjoining sections, and extended bearing sections carried by the links to engage the carrier drum and hold the ends of adjoining plates on the same are of travel. 116
ried by the links and engaging the surface of the drum. 7
4. A link for belt conveyers having a horizontally extending slot to receive hinge pins and spaced bearing portions extending downwardly from said slot.
5. A link for belt conveyers having a horizontally extending slot to receive hinge pins, and spaced bearing portions extending downwardly from said slot and diverging from one another.
6. A link conveyer belt comprising fiat conveyer links, short connecting links interposed between adjacent conveyer links, and a pair of hinge-pins at each joint by which said short connecting links are pivotally connected to the adjacent ends of said flat links, said short links having laterally projecting portions at each end of each link efiective to engage a supporting surface.
7. A link conveyer belt comprising fiat conveyer links having their ends slotted to provide laterally spaced bearing portions, a separate hinge-pin for each end of each conveyer link, additional links connecting said hinge-pins and mounted edgewise between said bearing portions, said additional links being cutout to provide open-sided bearings for said hinge-pins, and each additional link being provided with laterally projecting portions engageable with a supporting surface and substantially equally spaced from the longitudinal center line of said additional link.
