SCREEN CONVEYER.
Application led November l1, 192s. Serial No. 743,221.
My invention relates to certain improvements in screen conveyors, which are used to convey material through drying chainbers, in which heated air is circulated.
One object of the invention is to design the screen conveyor so that the sections of the screen can. be coupled in such a manner that the joint is of substantially the'same mesh as the body of the screen.
A further object of the invention is to allow the screen sections to accommodate themselves to each other in passing around the drums, or guides.
A still 'further object of the invention is to design the coupling so that any section can be readily detached and replaced.
ln the accompanying drawings:
Fig. 1 is a perspective view oi a portion of a screen made in accordance with my invention;
llig. 2 is a the screen;
Fig. 3 is a transverse sectional view on the line 3 3, Fig.. 2; and
longitudinal sectional view or" llig. 4: is a plan view of a portion or the conveyor shown in Fig. 2.
Referring to the drawings, l is an angular rail. The rails are located on each side the drying chamber and are spaced apart to allow the rollers 2, which carry the screen wnveyer 3, to travel freely through the drying chamber. The rollers 2 are mounted on bushings 22, which are located in the ends i of the links 5, 5a. The linlrs, 5a are tapered in the present instance, andthe ends 6 of the links are sp" ced a greateiidistance apart than the endsffl, and entend over the ends oi? the adjoining links. Pins 'l' extend through the bushings 22 and are secured to the ends 6 el' the links, as shown clearly in Figs. 3 and l. lllach pin has a head 8 at one end and-is'perforated at the opposite end for the passage of a Cotter pin 9 so that it can he readily detached, when necessary. The links 5 have lateral extensions 10 and 11. Depending from one end of the lateral extension llis a bracket 12 to which is secured the girt i3 hy bolts 14. Each girt has a series of periorations 15 through which the attaching wire 16 passes that secures the screen section 17 to the girt. The lower portion 18 of each girt is shaped in such a manner as to stiden it.
. The screen sections 17 are equal in length oft the side to the distance between the girts, but are oset, as shown in Fig. 2, so that one end a of a screen section extends beyond a girt at one end, while the end b stops short of a girt at the opposite end, as illustrated in llig. 2.
.At each end of the screen is a series or eyes 19 and 20. The eyes 19 ol one screen alternate with the eyes 2G oi an adjoining screen. A connecting pin 21 is passed through the eyes.. The pins are smaller than the eyes so that the links will have a limited longitudinal movement in respect to each other when passing around sprocket wheels, or curved rails. rlh-e girls retain the screen sections in a lined position in respect tothe links, which carry the screen sections. The loose pivot connection allows the screen sections to accommodate themselves to any irregularities in the movement of the conveyor.
By providing the eye and pin connection shown, the mesh is substantially the same as in the lood of each screen section, so that tine inateria will not nass through the screens at' the pins.
Attached to each linie of the conveyor cha-iu .are side danges 23, which overlap, as shown in Fig. l. ln order that the inner may he on the same piane, overlapping `portions are oli?- set, as illustrated in drawings.
lin the present instance each of the lsnges 23 has a hase 28a which is secured to 'the entension l0 el the links hy bolts 235, hut other means oi fastening the danges to the chain may he resorted to without departing rorn the essential features oi the invention. Each flange has preferably an outwardly extending lip 23, which reinforces the Hangs.
lt will he noticed that the pivots oi the screen sections are ona line with the pivots oi the chain 'and that the openings in the screen sectionsior the pins are o a greater diameter thanl the pins to allow a limited longitudinal rnovement ci each 'screen section. The 'screens are preferably connected to the girts soin-e distance from the pivot line of the chain, as shown clearly in Fig. 2.-
l claim:
1. rlhe combination in a screen conveyer, oi a series oi screen sections pivotall connected; and a. transverse girt locate near each pivot flor supporting the screen independent-,ly of the pivots.
2. The combination-in a screen eonveyer,
of side carryin chains; girts extending from one chain to t e other; screen sections carried by said girts; and pivot pins connectiner the screen sections, said pins being free o the supportin chains.
3. The com ination in a screen conveyer, of side carrying chains; girts extending from one chain to the other near the pivots of the links of the chain; screen sections carried by. said girts; and pivot pins connecting the screen sections, sald ins being on a line with the pivots of the c ain, but independent of the chain.
4. The combination in a screen conveyer, of side chains; girts connecting the chains; screen sections attached to the girts, said girts being also supported by the side chains; and pivot pins connecting t e screen sections on a line with pivots of the links of the chain but independent of the chain.
5. The combination in a screen conveyer, of two side chains consisting of links pivotally connected; a girt extending from one link to the other at one side of the pivot line of the links of the chain; screen sections, one end of each screen section bein attached to the girt and extending beyon the girt, and the other end .of the section pivotally connected together at a point some distance from the girts, the connection being loose to allow independent movement of the screen sections.
7. The combination in a screen conveyer, of two chains, each consisting of a seriesof links pivotally connected; rails over which the chains travel; girts extending from one chain to the other, and at. one side of the line through the` pivots of the links; and screen sections mounted on the links of the chainsand attached to the girts, the screen sections being pivotally connected on a line with the pivots of the chains, the connection being loose to allow the sections to have a limited longitudinal movement.
8. The combination in a screen conveyer, of two chains spaced apart,.each chain consistng of a series of long links; girts connecting the links of the chains on one side of the conveyer 'with the links of the chains on the opposite side thereof, said girts being back of the line through the pivots of the chains; screen sections mounted on the links and of a length substantially equal to the l length of the links, each screen section having a series of eyes at the ends, the eyes of one section alternating with those of an adjoining section; and a pin extending through the eyes of two adjoining sections, the pin being less in diameter than the eyes to allow the sections to have a limited, independent longitudinal movement.
9. The combination in a screen conveyer, of two chains spaced apart, each chain consisting of a series of long links pivotally connected; rollers at the pivots of said links; rails on which the rollers travel, the inner section of each link being channeled; screen sections substantially the same length as the links, the edges of the screen sections extending into the channels of the links; girts extendingfrom each link of the chain on one side to each link of the chain on the opposite side, the screen sections bein xed to the girts, said girts being back of t e line through the'pivots of the links, the screens having eyes at each end, the eyes of one screen alternating With'those of an adjoining screen; and pins extending through the eyes and connecting the several screens.
l0. The combination in a screen conveyer, of two chains spaced apart, each chain consisting of a series of inner and outer links, the inner links being channeled and having depending brackets.; girts extending from one chain to the other and secured to the brackets of the links; screen sections of substantially the same length as the links of the chains and attached to the girts, the girts being located back of the line through the pivots of the links; and pivot pins connecting the screen sections on a line with the pivots of the chains, the pivot pins bein less in diameter than the openings throng which they extend to allow each screen section to have a limited, independent longi tudinal movement.
l1. The combination in a screen conveyer, of side carrying chains composed of links pivotally connected; screen sections supported by the chains, the sections being pivotally connected at or near the pivots of the links of the chain; and side flanges secured to the links of the chain and extending at an angle in respect to the surface of the screen sections, the edge of one flange overlapping that of the adjoining Hangs.
