CONVEYER FLIGHT Filed Jan. l2, 1931 INVENTOR Hep/vavo H Qswcao/e/r ATTORNEY Patented Mar. 22, 1932 PATENT ori-TICE@ BEDMJDNDs H. PANGBORN, OF TAGOMA, `WASHJIIIiFGZlN' CONVEYER FLIGHT Application led January 12,1931.;
This invention relates to conveyers, and it has reference more particularly to improvements in insertable Hights for chain conveyers of that character now used quite extensively in saw mill operation, but which are applicable also to various other operations', such as in mining,` dredging, and elevating materials; the present invention being in the nature of an improvement upon that device disclosed in United States Patent No. 1,681,429, issued to me on August 21,1928.
The conveyer Hight embodied in the above patent briefly described, consisted of an angle iron bar equipped centrally with a trans- '15 verse Hange to which a link forming a part in y the conveyer chain, could be disconnectably and rigidly attached; the link having an open side which permitted it Hrst to be interlinked with the sections of a conveyer chain. It was found, however, that after some use, links having the open side would break, due to the excessive strain on the closed side of the link, andl this breaking usually caused delay and trouble.
In view of the above, it has been the principal object of this invention to provide a con- Y struction whereby all the undesirable features of the previous construction are overcome yet wherein all the desirable qualities are re- $0 tained. A
-More specifically stated, the objects of this invention reside in the provision of a conveyer Hight that is provided medially of its ends with a boss having keyways at front and interlocked connection the enlarged ends of U-shaped links which, after first being applied to their respective chain sections, are applied to the keyways and then locked functionally in place by the insertion of a key plate through the boss.
It is also an object 'of the invention toprovide a conveyer Hight of durable and substantial construction, that may be easily and quickly applied or removed, and which is relatively inexpensive.
Other objects of the invention reside in the various details of construction, and in th? combination of parts andin their mode of o eration, as will hereinafter be described.

Fig. 3 is aperspective view of one of the 60 Hights. Y
Fig. 4 is an enlarged cross section taken on line 4-4 in Figure 1. v i
Fig. 5 is a cross section on line 5-5 in Figure 4. .Y
Fig. 6 is a perspective view. of the locking key used in the Hight. y c Y Fig. 7 is a perspective View of one of the disconnectable links used with the Hight.
' Referring more v in detailto the drawings- 7o v1 designates, as a whole, a conveyer Hight constructed in accordance with the present invention, and 2 and 3 designate adjacent sections of a conveyer chain=between which the Hight is disposed. r v
In its preferred form of construction,the Hight is 1n the form of an angle iron bar embodying a Hat base, or horizontal Hange 4 and a vertical edge Hange 5 that is braced from the base portion by the two webs 6 near op- 80 posite ends of the bar. Centrally of ,the Hight, there is provided an enlarged boss: 7 and formed ytherein at the front and rear sides ofthe Hight, respectively, are slots 8 and 9. c These slots extend vertically and are 85 of `a dove-tailed character, and are open at their upper ends to the top side ofthe Hight, but are closed at their lower ends by the base flange 4. Removably Htted within the slots 8 and 9 respectively are the inner end portions 90 of `U-shaped links` 10-10; each of which is provided at the ends of the leg portions, with enlarged heads in the form of cross4 bars 11,
as vshown best in Figure 7 which are ada ted to be slipped downwardly into the ovetailed slots to provide an interlocking connection whereby the links are held attached to the Hight. After being applied to the' slots, the two links may be held functionally connected with the Hight by the insertion` of a locking key 13 within a keyway or pas; sage 14 formed transversely throu h the boss; the passage bein so arran ed t at the key, when inserted, will project etween the end portions of each of the links 10- 10 and will thereby keep the links from being dislaced upwardly froin their respective slots.
he key plate is shouldered, as at 15,'near one end to engage with the boss near'the inner end of thc passage to thereby limit .its movement inwardl and it is provided with a hole 16 through tlli'at end for receiving a key 17 to hold it against outward displacement.
Assuming that the parts are so constructed, the Hight is applied to the sections and 3 of the conveyer chain by first inserting. the U-shaped links 10-10 through the end links of the chain sections, then slipping the enlarged end portions 11 of the links downwardly into the slots 8 and 9 of the Hight, then inserting the locking key 13 to hold them functionally in place. With this construction, the links 10-10 are securely and rigidly anchored to the Hight and the Hight serves also as a connecting link in the complete conve er.
he construction, while permitting of ready assembly or disassembly of parts, provides a very substantial construction, and due to the open ends of the U-shaped links, the Hight may be easily and quickly removed to rmit the removal and re lacement of bro en chain sections, or for ot er (purposes.
Such Hights are especially suite for use with conveyers in saw mills, mines, elevators, coaling stations, dredges, etc., and can be made 1n various sizes in accordance with the purpose for which they are to be used.
Having thus described my invention what I claim as new therein and desire to secure by Letters Patent, is:
1. In a conveyer of the character described, a cross Hight having front and rear face slots, links interconnected with the ends of sections of the conveyer forwardly and rearwardly of the Hight and having ends applied within said slots in an interlocked connection.
2. In a conveyer of the character described, a Hight having slots formed in its front and rear faces, and open end links interconnected with sections of the conveyer at opposite sides of the Hight and having enlarged ends applied within said slots in an interlocked connection.
3. In a conveyer of the character described,
- a Hight having slots formed in its front and rear faces, and open end links interconnected with sections of t e conveyer at opposite sides of the Hight and having enlarged ends applied within said slots in an interlocked connection, and locking means for retaining the links against displacement from the slots.
4. In a conveyer of the character described, a Hight formed ywith a central boss having alined, dove-tailed slots in its opposite faces,
U-shaped link sections interconnected with l sections of the conveyer belt at opposite sides of the Hight, and aving enlargements at their ends contained within said doveta'iled slots, and a key projected through the bars and engaging the link ends to prevent displacement from the slots.
5. A conveyer Hight com rising a cross bar adapted to be disconnectab y associated with sections of a conveyer chain; said bar having a central boss provided at front and rear sides with dove-tai ed slots, opening at one end to the face of the boss, a U-shaped link at each side of the Hight, adapted to be interlocked respectively with the conve er chain sections at opposite sides of the Hig t and having enlarged cross heads at its open end adapted to be applied within said dove-tailed ooves to eHect an interlocking connection; said boss having a transverse passage, and a lockin key extended therethrough and engaging said links to prevent displacement of their ends from the slots.
