CONVEYER.

Application filed April 23,

The invention. relates to conveyers and refersmore particularly to that type havlng an invention is to simplify the construction of conveyer and at the same time provide a conveyer which is practicable. Another object shoes that they may be readily advanced along a track, which is curved either in horizontal or "vertical planes. With these as well as other objects in view, the invention resides in the novel features of construction and combinations and arrangements of parts as more fully hereinafter set forth. In the drawings Figure 1 is a side elevation of a portion of a conveyer embodying my invention;

Figure 2 is an end elevation, partly in section, thereof; I

Figure 3 is a cross sect of Figure 1;

Figure 4 is a view'simil ion on the line ar to Figure 2, showing a modification.

The conveyer has the track 1, which is adapted to be supported at suitable points spaced longitudinally thereof by the bars 2, which are secured to the tracks by the bolts 3 and the nuts 4. The track, as shown, is an inverted T-bar having the web 5 and the aligned lateral flanges 6 at the lower edge of the web, the bars 2 being secured to the web.

The conveyer has the power connection 7, which extends below the track 1 and, as shown in the present instance is a power driven conveyer chain, the links of which are pivotally connected to provide for thenecessary flexibility of the chain to take care of curves in the track, either horizontally or vertically. The conveyer also has the shoes 8 connected to the chain at longitudinally spaced points, but one shoe being shown in the present instance.

. Each shoe 8 has the lateral portions 9 extendinglongitudinally below the lateral flanges 6, the upwardly extending portions 1O at the outer ends of the lateral ortions 9 and extending longitudinally o the edges of. the flanges 6, .and the lateral portions 11 extending inwardly from the upper ends of the uply above the flanges 6'and slidably supported upon the same. Each shoe further has'the portion 12 depending from the lower lateral portionstl'and adapted tobe secured to the upwardly extending ear 13 of the chain attachment link 14.

I

In the modification of the shoe along th curved either in t planes, wardly shown in Figure 4, the shoe is made up ofthe cooperating sections 19, which are alike. Each section has the lower lateral portion 20, the upwardly extending portion 21 and the upper lateral inwardly extending p6rtion22 corresponding to the portions 9, 10 and 11 of the shoe shown in Figures 1, 2 and 3. Each section also has the port on 23 depending from the lower lateral portion 20 and spaced from the depending portion of the other section when the two sections are secured together. Each section further has the front and the rear transverse walls 24 which are adapted to have edge to edge engagement when the sections are secured to each other. The attachment part 25 of the conveyer chain 26 extends upwardly between the depending portions 23 and between the front and the rear walls 24 and is secured to the sections by means of the bolt 27 and the nut 28, which secure the sections to each other. The work carrier may be carried by the shoe in'much the same manner as the work carrier 17, shown in Figures 1 and 2. I

What I claim as my invention is:

1. In'a conveyer, the combination with a track and a conveyer power connection below said track, of a conveyer shoe formed in one piece having a portion connected to said power connection and another portion slidably mounted upon. and depending from said 100 track, and a work carrier beneath said shoe and carried thereby. j

2. In a conveyer, the combination with a track, of a conveyer shoe having a portion integral therewith and slidabl mounted upon said track and connected thereto, a power connection below said track having a art connected to and depending from said s 0e,

and a work carrier suspended from said part. 3. In a conveyer, the combination with a track and a power chain below said track having an attachment link, of a shoe slid-' ably mounted upon and having an interlocking connection with said track and depending therefrom, means connecting said shoe to said attachment link, and a work carrier beneath said shoe connected to said attachment 7 Y ment, means extending through. said dependlink.

'4. In a conveyer, the combination with a track having alateral flange, of a conveyer shoe having a portion wardly extending portions at opposite sides of said track, and an inwardly extending portion above said flange and slidably engaging the same, said upwardly extending portions and inwardly extending portion being flared at their front and rear ends, means connected to said shoe for advancing the same along said track, and a work'carrier below and carried by said shoe.

, 5. In a conveyer,vthe combination with a track having a lateral flange, of a convey er shoe having a portion below said flange and extending longitudinally thereof, upwardly extending portions at opposite sides of said track and extendinglongitudinally thereof.

and an inwardly extending portion above said flange and extending longitudinally thereof and slidably engaging the same, all of said portions being flared at their front and rear ends, meansconnected to. said shoe for advancing the same along said track, and a work carrier carried by said shoe. I

6. ha conveyer, the combination with a track having aligned lateral flanges, a conveyer shoe having a portion below said flanges and extendin longitudinally thereof, up-' wardly exten ing portions extending longitudinally of the edges of said flanges, and inwardly extending portions extending longitudinally above'said flanges and slidably engaging the same, all of said pprtions being ared at their front and rear ends, a power connection below said track and connected to said shoe, and a work carrier beneath said shoe and carried thereby.

-7. In a conveyer, the combination with a track having aligned lateral flanges, of a conveyer shoe having cooperating sections with portions extending longitudinally below said flanges, upwardly extending portions extending longitudinally of the edges of said flanges, and inwardly extending portions above and slidably engaging said flanges, all of said portions having'flared front and rear ends, means for securing said sections together, means for advancing said shoe, and a work carrier beneath and carried by said shoe.

8. In a conveyer, the gombination with a track having aligned lateral flanges, of a conveyer shoe having cooperating sections below said track, up-

with lateral portions extending longitudinal- 'anges, and lateral portions and rear walls having edge to edge engageing portions for securing said sections together, means for advancing the said shoe, and a work carrier carried by said shoe.

9. In a conveyer, the combination with a track and a conveyer power connection below said track, of a conveyer shoe having a portion connected to said power connection and having upwardly extending portions curved longitudinally opposite the side edges of the track and terminating in inwardly extending arms slidably engaging the upper surface of the track.

10. In a conveyer, the combination with a track and a.conveyer power connection below said track, of a conveyer shoe having a portion connected to said power connection and having another portion provided with spaced inwardly opening grooves adapted to slidably receive opposite edge portions of said track.

11. In a conveyer, the combination witha track having oppositely extending flanges and a conveyer power connection spaced from said track, of a conveyer shoe having a portionconnected to said power connection and having other portions extending upwardly upon opposite sides of said flanges and provided with grooves adapted to slidably re ceive portions of said track flanges.

12. In a conveyer, the combination with a track having oppositely extending flanges and a conveyer power connection spaced from said track, of a,conveyer shoe having a portion connected to said power connection and having upwardly extending portions provided with grooves adapted to slidably receive portions of said track flanges, the side walls of said grooves opposite the edge portions of the track flanges being curved longitudinally to facilitate movement of theshoe along the track.

13. In a conveyer, the combination with a track having oppositely extending flanges and a conveyer shoe having a depending lug connected to said power connection and having portions extending upwardly upon opposite sides of the track flanges and terminating in'inwardly extending arms forming grooves for slidably receiving portionsof said track flanges.

In testimony whereof I aflix my signature.
