INVENTOR ANTHONY J. SICILIANO EGG ESCALATOR BELT ASSEMBLY FIELD OF INVENTION The present invention relates to escalator belt assemblies and more particularly to an escalator belt assembly for automatically transferring eggs or like objects from one elevational level to another.

DESCRIPTION OF THE PRIOR ART In the previously known escalator belt assemblies for eggs and like objects resiliently deformable bands were generally glued directly to a transmission belt member. Another way of assembling these belts would be to glue an entire sponge-like resilient section to a cloth belt which in turn was attached to a V-belt section with screws spaced approximately every three inches. In such assemblies it was necessary to allow the cloth or backing member to gather on the straight pull since the cloth or backing member had to ride piggyback over the transmission belt. As the assembly rode around a pulley, the gathered belt would straighten out. This constant gathering and stretching of the assembly resulted in short escalator belt assembly life. Replacement of the entire assembly was necessary and, of course, expensive.

Examples of prior escalator belt assemblies of the general type described above are disclosed in U. S. Pat. No. 3,319,776 and U. S. Pat. No. 3,446,332.

SUMMARY OF THE INVENTION The present invention comprises a new and improved escalator belt assembly for eggs and like objects in which the escalator belt comprises a resiliently deformable load carrying section and a transmissions section, portions of which are detachably connected to each other, thus affording the facility of replacing worn parts.

Another object of this invention is to provide a more economical escalator belt assembly.

An additional object of this invention is to simplify replacement of the escalator belt assembly.

A further object of this invention is to provide an escalator belt assembly in which components thereof are easily replaced.

Still a further object of this invention is to provide an escalator belt assembly which in operation is not affected by humidity.

FIG. 1 represents a side elevational view of the escalator belt assembly according to my invention;

FIG. 2 represents a segment of one embodiment of an escalator band according to my invention;

FIG. 6 is a plan view of the article contacting, carrying and transferring section of the escalator band of FIG. 5 prior to assembly and with portions broken away;

FIG. 7 is a side elevational view of the article contacting and transferring section shown in FIG. 6; and

FIG. 8 is a sectional view of the escalator band assembly taken along line 8-8 in FIG. 5.

DETAILED DESCRIPTION OF THE INVENTION Referring now more particularly to the drawings, the escalator belt assembly according to my invention is shown in FIG. 1 as including an endless escalator band 10 comprising an array of radially outer resilient members 11 for deformably contacting, carrying and transferring eggs such as E or like objects from an elevational level L, to another elevational level L,. The resilient members may be of sponge-like foam material and in the form of pads or a single web with a plurality of slits. The escalator band 10 also includes a radially inner transmission member 12 to which the array of radially outer resilient members 11 are secured. It is noted that in accordance with this invention portions of the array of resilient members 11 and the transmission member 12 are assembled in detachably secured relationship to simplify assembling and to facilitate the replacing of only parts needing replacement, as will be more specifically described hereinbelow.

In operation the conveyor band 10 is trained over a pair of drive wheels 13 and 14 which are rotatably supported on a frame member 21. It is to be clear that the escalator band 10 may be used to raise eggs from a lower level L to a higher level L, as well as to transfer them from a higher level L, to a lower level L By way of example, however, it is noted that eggs fed into the escalator system at level L, are sandwiched between a belt 15 trained over drive wheels 16 and 17, and the resilient member 11 which deformably compress eggs E fed therebetween in sandwich-like relationship. This yieldable compression of members 11 against an egg E and belt 15 prevents rolling of the eggs E due to gravity 7 and provides for a gentle deposit of the egg E, at the next level L The belt 15 is shown as a flat belt but it could be similar in construction to the escalator band 10. Members 18 and 19 are tension idlers for the belt 15. Reference 20 designates an adjustment means for the drive wheel 14, whereby its distance from wheel 13 is adjusted to facilitate belt installation and to take up slack.

Although FIG. 1 shows the lower run of the escalator band 10 as being provided with the belt 15 spaced therefrom for transferring eggs from level L, to level,, it is clear that the upper run of escalator band 10 .may be provided with a spaced parallel portion of a belt similar to belt 15 to perform the transferring function thereat.

In the embodiment of FIGS. 2-4 of my invention are shown details of an escalator band in which an array of radially outer resilient pads 111 are secure as by bonding to rigid strips 116, for example, by a layer of glue or cement 117. The escalator band 100 also includes a radially inner transmission member 112 in the form of a link chain provided with alternate conventional links 113 and connector links 114, which include transversely extending flat plates 115. As is conventional, the connector links 114 are detachably secured to the links 113 and may if desired by replaced individually. The plate 115 is provided with a pair of spaced apertures 118 to receive rivets 119 which pass through and secure the rigid strips 116 to the connector links 112. From the foregoing, it is clear that in the event that some of the resilient pads 111 become damaged or excessively worn from use, these pads along with their respective connector links 114 may be individually replaced while the serviceable pads 111 are retained for further use instead of being replaced along with the damaged or worn pads as in escalator bands of the prior art.

According to a further embodiment of my invention as shown in FIGS. 5-8, an escalator band 210 comprises an array of radially outer resilient article contacting, carrying and transporting members 211 bonded to a flat backing of plastic material 215. As shown in FIGS. 6 and 7

opposite ends

217 and 218 of the backing 215 are reinforced by strips of glass tape 225 bonded thereto. Holes are formed in the

ends

217 and 218 of the backing 215 and provided with reinforcing eyelets 226 and 226'. The escalator band 210 also comprises a radially inner transmission member 212 which is in the form ofa V-belt. The V-belt member 212 comprises a pair of

opposite ends

221 and 222 which are held together by a pair of

plates

223 and 224. The outer article contacting, carrying and transferring members 211 are assembled onto the inner transmission member with the ends 218 superposed over the end 217 and angularly spaced from the

ends

221 and 222 of the transmission member 212 approximately 180 therefrom. The outer article contacting, carrying and transferring member 211 is then secured to the inner transmission belt member 212 by a single screw 219 inserted into the aligned

apertures

226 and 226 and screwed into the transmission belt 212. Insertion of the screw 219 is facilitated by a cut out portion 219 in the pad member 211. Thus the escalator band assembly 210 is made up of a V-belt to which a section of plastic belt 215 with foam pads secured to it is attached by one screw. Replacement of the outer plastic belt 215 and the array of foam pad 211 is quickly and easily accomplished since the attachment is provided for by a single screw 219. A further advantage resulting from the use of a single attaching screw 219 is that the assembly is not affected by atmospheric conditions as in the previously known escalator bands in which expansion and contraction impaired the normal function of the belt. Further, attachment of the escalator band members by the single screw 219 affords the arrangement of a free floating sponge belt attached to a V-belt transmission and tracking element which avoids the constant gathering and stretching of the outer escalator member superposed over an inner belt member, riding in piggy-back relationship in the previously used escalator bands of the prior art.

In operation the escalator band 210 is trained over a pair of pulley wheels 213 and 214. To facilitate installation of the escalator band 210 over pulleys 213 and 214 and also to adjust the belt tension adjustable screw mechanisms 220 are provided to position pulley 214.

Although I have described my invention with a certain degree of particularity, it is understood that the present disclosure has been made only by way of example and that numerous changes and details of construction and a combination in arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
