Specification of Letters Patent.

Patented Oct. 3, 1911.

Application filed April 15, 1910. Serial No. 555,684.

T 0 all whom it may concern:

Be it known that I, ISAAC CHRIST, a citi zen of the United States, residing at Tama qua, in the county of Schuylkill and State of Pennsylvania, have invented certain new and useful Improvements in Conveyers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledv in the art to which it appertains to make With this object in view, my invention consists in the construction and combinations of parts as herelnafter descrlbed and claimed.

In the accompanying draw1ngF1gure 1 is a side view of a conveyer chain with the attachments placed in pos1t1on,sh0w1ng how the attachments are held on the chain without bolts. Fig. 2 is a top plan view of the same. Fig. 3 is a side elevation of a portion of the chain, to which a bucket for carrying coal may be secured. Fig. 4 is a similar view at right angles thereto. Fig. 5

is an end view of the bucket attachment detached. Fig. 6 is a top plan view of the same. Fig. 7 .is a perspective view showing one of the sides of the flight carrying attachment. Fig. 8 shows one side of the attachment applied to a modified form of chain link. Fig. 9 is a perspective view showing one link and the conveyer attachment mounted thereon. Fig. 10 is a bottom view of one of the securing bolts, showing the spring washer thereon and Fig. 11 is a detached elevation of the conveyer flight.

tion 3. These links are preferably arranged in pairs, as best shown in Fig. 2, one pair being used together .and the other pair on the outside thereof, the pairs being united together by pivot pins 4.. In Fig. 8 is shown a modified form of link, in which the enlarged port-ions 2 are united by a cross brace 5.

The attachment for holding the conveyer flights or buckets is shown in Figs. 5 to 7 and consists of two similarly shaped but oppositely located symmetrical parts. As shown in Fig. 7, one form of this attachment consists of a body portion 6, provided with a longitudinal groove 7 on its interior, the lower part of the wall of said groove being provided with an upwardly projecting rounded portion 8, adapted to fit into the portion 3 of the chain link. The upper wall of the groove is cut away so as to fit around the enlarged portion 2 of the chain link. In the form shown in Fig. 7, the attachment is provided with a transverse groove 9 for the reception ofthe lower edge of the conveyer flight 13, and is also provided with an upwardly projecting transverse portion 10, provided with a hole 11 for the reception of one end of a bent brace or yoke 12, shown in Figs. 1 and 2, which brace secures the flights to the attachment by means of split spring washers 14E, slipped into a grooved portion of the ends, or any desirable means of securing the brace in its position, passing through theflight and the parts of the attachment, may be used. The conveyer flights 13 are centrally cut away as shown in Fig. 11 to provide engaging members 13 which fit down over the sides of the sections 6 and hold said sections against sidewise displacement. The part 10 projects inwardly over the chain, as shown at 15, until it meets against a corresponding part on the other half of the attachment.

On one side of the groove 9 is a projecting lug or extension, against which the lower edge of the corresponding fllght 13 bears.

In assembling a conveyer chain, the halves of the attachment are simply slipped onto the upper member of the link from the outside of the link, as shown in Fig. 1, with flights 13 put on with their engaging members 13 overlapping the attachment on the outside and resting with the cut away edge in groove 9. The ends of brace 12 are passed through holes 11 in the attachment and flight, and the split spring washers 14 driven home, makes a complete fastening, such as shown on the right hand of Fig. 2.

Referring especially to Fig. 8-, a modified form of link is shown, having a cross piece 5, connecting the enlargements 2 In this case, the central part of the attachment is, of course, cut away so as to fit around the cross piece 5, preventing the longitudinal movement of the attachment on the link.

In case it is desired to use buckets on the conveyer chain instead of flights, the modified construction shown in Figs. 3 to 6 is employed. In these figures, substantially the same method of securing the attachment to the chain links is used, as shown in Fig. 1, except that the parts 20, which rest on the top of the respective chain links, do not extend across the link and abut against each other, as do the parts 15 in the form shown in Figs. 1 and 2. In this modification, the halves 21 of the attachment fit around the chain links, one being slipped on from the outside on each side of the link, the parts 22 fitting on the inside of the links, and the parts 20 fitting on the outside of the links. These halves are each provided with inclined extensions 16, provided with perforations 23, and on these inclined extensions buckets 18 are placed, each having an inclined lower edge and provided with studs or bolts 17, which project through the perforations 23 and are held in position by the split washers 19, which are driven into cut away portions on the bolts 17, or nuts may be used, if desired.

It will be noted that my attachments are simply slipped onto the chain links and do not need to be bolted thereto. They are secured to the top member of the link and are self-sustaining. All others known to me have the attachment bet-ween the top and bottom of the link, or in the slot. By having the flight coming down into the grooves of the halves of the attachments, and having the flight overlapping the attachments the attachments are thereby firmly held upon the chain links.

in place by 'the conveyer flights or the buckets secured to the halves thereof.

I claim 2- 1. The combination of a conveyer chain provided with open links, an attachment comprising sections constructed to conform with and embrace portions of said links, said sections provided with grooves; conveyer plates seated within said grooves, and means holding the conveyer plates to said sections.

2. The combination of a conveyer chain provided with open links, an attachment comprising sections constructed to conform with and embrace portions of said links, said sections provided with grooves, conveyer plates seated within said grooves and having their outer ends fitting over the sides of said sections, and yokes disposed lengthwise of the conveyer plates and securing said plates to said sections.

3. The combination of a conveyer chain provided with open links, each link having a central enlargement provided with a recess on its inner part, an attachment made in halves, said halves being adapted to he slipped over said links from the outside, said halves each having a groove into which the side of the corresponding chain link fits, and provided with a projecting portion engaging the groove in the enlarged portion of the chain link, and also provided with a transverse groove, conveyer flights, one adapted to be fitted into the groove of the halves of each attachment, and means for securing each of said flights to the corresponding attachment, substantially as described.

4. The'combination of a conveyer chain made of open links, each of said links having enlarged central portions provided with curved recesses on their interior, an attachment made in two halves adapted to be slipped onto said link from the outside, each half being provided with a groove adapted to receive the side of one of the chain links, with a projection adapted to fit in the central recess of the corresponding chain link, with a transverse groove for the reception of the conveyer flight, and with an upwardly and inwardly projecting portion provided with perforations, a perforated conveyer flight for each of said attachments, adapted to fit into the transverse grooves thereof and rest against the enlargements thereof, said enlargements fitting against each other centrally in the line of the chain, curved braces, one passing through the holes in each of the conveyer flights, and the halves of the corresponding attachment, and spring washers adapted to be driven over the ends of said braces to bind the conveyer flights and attachments together, substantially as described.
