SIGNORS, BY MESNE ASSIGNMENTS, TTO GOODMAN MANUFACTURING COMPANY, 0F CHICAGO, ILLINOIELA CORPORATION' OFILLINOIS I i ApplicationfiledlMarch 14, 1929. Serial No. 346,977.

The particular object of the invention is 5 an improved' conveyer construction of the character mentioned wherein meansare provlded for greatly facilitating connection and disconnection ofadjoining conveyor troughs or sections.

ence to an application for U. S. Letters Pat ent, Serial No. 346,650, filed on the 13th day of March, 1929 by Angus 'JfHatt, covering a similar conveyer construction and'fastenmg means on which the present nvention is ventions have in common are claimed in said application and disclaimer thereto accordingly is made in the present application.

Heretofore, the common practice has been to connect the conveyor sections to each other by means of bolts and nuts, the bolts extending through corresponding pairs of perforate lugs or ears forming parts of bolt straps troughs or sections. Obviously, placement of the bolts in the perforate lugs and Screwing up the nuts draw thetroughs or -sections of the conveyer together when they are being extensive use. With the present invention,;

it is sought to reduce'to a minimum the time necessary to connect or disconnect the con veyer sections.

together by the old nut'and bolt connections above mentioned, it" frequently is found difficult to assemble the sections properly and secure the bolts and nuts in place-whenlthe conveyersections or the bolt straps are bent It is desired at this point to make refer-- an improvement. Such featuresas-'th'eseinprovided for the purpose at the ends of theassembled, or, unscrewing of the nuts and removal of-the bolts when sections are belng Where conveyer sections are to be joined or otherwise distorted. Under these conditions,'proper alinement of the perforate fas tening lugs in order to place the bolts-in po'sitionttherein without damaging them so' that the nuts cannot" be put in place, is notreadilyaccompli'shed. Withthe present in-' vention,- it is intended that the fastening means used shall beunthreaded, and in fact, V

be adapted tobe driven into place to aline the" fastening lugs without danger of damaging the fastening device so that-it cannot be readily removed or replaced when desired.

*In the shaker type of conveyer, the adj oi n-' ing troughs or sections, when assembled,

overlap slightly at their ends, and,-when thesections are properly positioned with reference to'each other, the bolt straps and the perforate-fasteninglugs thereon should be in Substantial alinement and abutting relaveyerv sections, which are subjected to very rough usage, are often bent out of" shape tion to each other. i As stated before, thegcon and consequently the fa stening lugs do not 7 properly aline when the sections are assembled. In the proposed arrangement, it is intended that the fastening means used,

when in place, shallserve not only to draw the fastening lugs closely together, but also to cause the lugs to be broughtv into proper alinement--with reference to each other. In-

this manner proper overlapping and nesting of the ends of the conveyerfSectionswill'be assured. I r v y 5 A particular object of the invention is the provision of'fastening meanswhich may be' used for connecting the conveyer sections without the necessity of changing the conventional construction of the sections or any of the usual parts mounted thereon. Thus,

the connecting means may be applied to the many 'units of this and similar types already in use.

It is intended that the construction and by unskilled help and without the use of special I tools. The fastener ,partsare de-.

signed to be readily manufactured in large quantities from standard stock in order" to of a pair of adjoining shaker conveyer sections or troughs of conventional construction with the improved joint or connection therebetween ..Fig. 2, a transverse section taken on the line 22 of'Fig. 1, except that the fastening device on the right-hand side appears in full, showing the manner in which the per forate lugs or cars on the ,ends of the bolt straps .are located on the conveyer sections Fig, 3, an enlargedside elevational view of one of the fastening devices for the conveyer sections as it appears when assembled, certain of the parts being broken away and the cooperating pair of lugs shown in longitudi nal section, so as to make clear the relationship between the various parts when the device is in use; I

adjoining shaker conveyer sections or troughs 1, 2 of conventional construction. Fig. 2 showsclearly the cross sectional form of the sections, from which it will be noted that each section, which is preferably made of heavy gage sheet metal, is provided with upwardly and outwardly inclined sides 3, 4. Both sides of each sections are stepped or offset between their top and bottom edges to provide a horizontal ledge or shoulder 5.

Horizontal edge portions 6 are formed integral with the sides3, 4, and the bottom of.

the conveyer trough or pan is fiat, as shown at 7.

' 'Suitably secured, as by welding, to each conveyer section or troughat each end there-.

of is the usual bolt strap 8. This member preferably is made of strap iron. Referring to Fig. 2, it will be noted that bolt strap 8 bears against the under side of the bottom 7 of the pan orconveyer section and near its There is shown in Figs. 1, 2 and 4 a pair of,

ends is bent so as to form outwardly and downwardly projecting lugs or ears 9, 10 having longitudinally-disposed openings therethrough. The extremities of bolt strap 8 are bent upwardly and secured, as by rivets 11, to angle plates 12,13. These plates are suitably mounted, as by welding, on the under side of the offsets 5 in the sides of the con veyer section.

' It will be noted from Figs. 1 and e that a bolt strap'8 is provided at both ends of each ofthe conveyer troughs or pans. In the same figures, it will be seen that, where the adjoining conveyer sections are connected together,'ione of the bolt straps 8 included in this connection, is located at the extreme end ofits section, so that its outer edge 1: flush with the end of the section. The cooperating bolt strap 8 on the adjoiningiconveyer sec tion which is included in thisconnection however, isset back a short distance from the end ofthe section, to permit theconveyer sections, when .assembled, to overlap" somewhat and nest one within the other as shown at 14 in Bolt straps 8 on the several conveyer sections are so proportioned'that, when two sections are properly assembled as shown in Fig. 1, the openings or perforations in fastening lugs 9,10 of the bolt straps and the lugs them-' selves will bein alinement with each other. A pair of conveyer sections having been placed with their ends adjoining and in overlapping relation as shown inFig. 1, the corresponding pairs of lugs 9, 10 now adjoin each other and are ready to receive the fastening means. A separate set of fastening means or separate fastening device is used for each pair of cooperating lugs, one for one side of the conveyer and another for the opposite side at the points of connection of the conveyer sections. v v V The improved fastening devices used for this purpose each comprises three members, viz., a pin 15, a link or strap 16 and a'taper keyor wedge '17. The preferred form and. construction of these members appear clearly in Figs. 3 and 5. Pin 15, wh ich is substantially circular invertical cross-section throughout its length, is formed with an elongated straight body portion 18 the straight end 19 of which is'slightly tapered as seen at 19. Atits opposite end pin-15 is bent upwardly and slightly over its straight body portion 18, so as to form asubstantially straight end portion;20 which is disposed at an angle to the longitudinal'axis of the body 18 of the pin. The inclined end 20 of the pin is provided with a transverse opening 21 extending therethrough, which'is disposed longitudinally 10fv the bodyv of the pin. Preferably, opening 21 is substantially rectangular in vertical cross-section in order to properly coactwith the other parts of. the fastener. Attention is directedto the fact that although sax.

the several portions of pin 151; are; bent relativc; toeachother asi-descri'bed, ,they;-all are disposed substantially in a .sin-gleplane, lt Willbe noted that the-inclined ,end of p n lntapersrsomewhat from its base toward its free end and the freeend thereof is provided with; an, inclined surface-2 2l The purpose of these featurcswill appearlater. I

When pair'of conveyor troughs or pans havebeen assembled substantially in the position shown in Fig, 1, the-free enid 19 of the P11115318 inserted, inithe outerend of theopening through the left-hand ear or T lug 9, and,

TheneXtstepisto securerthe strap or-link 16in place. The V body-portion 23, of this member is substantially straight andof elongated form, Preferably, the.--member-is rec: tangnlanin vertical cross-section, the width of the member being; considerably greater than itsthickness, as appears from Fig. 5.

ziAt itsright-hand end =link16-is bent so as to ,torm a downwardly and outwardly inclined end portion 2e, anda circular openingis formed-therethrough. The opposite end of link 16 is provided -with as inclined opening 26 ex tending-fromthe underto the upper face thereof.

The inclined'or' bent and 24 0f strap 16 is,

slipped over-thetapered 'free end 19 of pin 15, previously placed in the fastening lugs,

as shownin Fig 3.v The opening 25 in thethe lugs 9, whereby the inclinedvend 20,

The straight end-of-link16 is shoved down over the inclined end of the pin untilthe; lower portion of link 16 atthe left-hand side of opening 26 isin contact at 27 with the downwardly and outwardly inclined surface 28-of the left-hand side ofthe inclined end 22 of the pin, see Fig. 3. Open-ing26 is-so located and proportioned as to, permit the described movements of the parts.v At this time, it-will be noted too, the upper portion of -opening 2l in the inclined, end 29 ofthe pin; extends somewhat-above the upper surface of the body portion 23 of link 16-.

Thenext and last step} is the placing in position of the third memberofthe fastening device, namely, the tapered keyorwedge 17. This member,as shown in Fig.5,is preferably rectangular in vertical cross-section and taperstoward its free end 29, theopposite end thereof being turned substantially at right angles to the body of the member so as togform a head or driving, portion, 30. The free end 29 of key 17 is placed in the righthand end of opening 21 in the inclined end 20' of thepin above link 16, as shown in Fig. 3-,,and, with the aid of a hammer or of a suitable tool applied to its head 30, wedge 17 isrdriven' through the opening. Movementof thewedge through opening 21 re sults in the wedge forcing the straight body portion 23 of link 16 inwardly on the inclined end 20 of pin 15 towards the body thereof, the link swinging about-point 31 as a pivot, Fig. 3.; Upon reference to this, figure, it will be obvious that: this clamping ofthe straight under side oflthe body portion of the pivotally mounted link 16 againstthe outer surfaces of the adjoining fastening lugs 9,.will cause accurate alinement of the lugs with each other. Therefore, the, conveyer. units willbeproperly positioned laterally with reference to each other, as a result of this clamping action. of the fastener.

Opening 26 in the body portion of link inward swinging'inovement of the; left-hand end of the llnkas the wedge is driven into place will result in a longitudinal drawing together or shortening of the over all length of these two interconnected, L-shaped members, namely, pin 15 and link 16. Consequently, since the bent ends :of these mem- 16 is .made large enough to permit freemove bers arein engagement with the outer ends of the adjoining fastening lugs 9, pin 15 at 32 and33 and link 16 at 34 E(Fig..3) this clamping action of the members 15and 16will cause Alinement of the coacting lugs 9, when the fastening means are 1n place is assured by the proper shaping and proportioning of the several parts, so that when in place-they will assume the relationship to each other shown in Fig. 3.

When it is desired to disconnect adjoining sections of the conveyer, as for instance to shorten the conveyer, the fastening means described are readily removed by driving out the wedge 17 after which the straight end of link 16 is swung outwardly, and this member and pin removed from the fastening lu 's o A modified form of the connection between the left-hand extremities of pin 15 and link 16 appears in Fig. 6. In this construction,

the parts which go to make up the fastening device are to all intents and purposes the same as those of the principal form, except that the left-hand end of pin 15 is provided with a straight or flattened portion 22", to which the implement is applied to drive the pin into place in the lugs. In addition, opening 26 in the body of link 16 is formed at right angles to theupper and lower faces of the link, instead of at an incline to these surfaces as in the principal form of the invention. 7

The mode of applying and removing and functioning of the modified device are the same as described with reference to the form of the invention shown in Figs. 1-5, inclusive.

IVhile the two forms of fastening means herein have been described with the pin or bolt element inserted at the left-hand sideof the coacting fastening lugs, it will be obvious that the pin may be inserted from the right-hand side and the other parts reversed accordingly.

This invention provides a conveyer construction employing a highly desirable type of joint or connection between the pan sections or troughs of the conveyer thereby considerably facilitating assembly and disassembly of the conveyer. The fastening device used for connecting the conveyer sections together being of simple construction, it is particularly adapted for manufacture on a quantity production basis and consequently at low cost.
