MICHAEL G. GRANEY, OF HOOSICK FALLS, NEW YORK.

CONVEYER-BELT.

Specification of Letters Patent.

Patented Feb. 9, 1909.

Application filed May 20, 1908. Serial No. 433,890.

To all whom it may concern: y

Be it known that 1, MICHAEL C. GRANEY, a citizen of the United States, residing at Hoosick Falls, in the county of Rensselaer and State of New York, have invented new and useful improvements in Conveyer-Belts, of which the following is a specification.

This invention relates to improvements in conveyer belts for grain harvesters and other machines and conveying apparatus generally, and particularly to means for connecting the meeting ends of the belt and for attaching the intermediate cross strips or slats thereto.

The primary object of the' invention is to provide a simple and effective construction of means for connecting the ends of the belt which may be readily applied and permits of ready renewal or repairs of the parts thereof, which will automatically take up the slack in the belt and operates without impairing the iiexibility of the ends of the belt, and which is adapted to strengthen and relieve the ends of the belt of the pulling strain ol the automatic take-up means.

A further object of the invention is to provide a novel construction of means for attaching the intermediate cross bars or strips to the body of the belt in a convenient, firm and secure manner.

With these and other objects in view, the invention consists of the features of construction, combination and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying drawing, in which Figure 1 is a top plan view of the meeting ends of a conveyer belt constructed and connected in accordance with my invention, the

covering fia-p upon one of the ends of the belt being broken away to disclose the oonnections. Fig. 2 is a longitudinal section of the same with the flap in operative position, Figs. 3 and 4 are perspective views of two of the coupling brackets. Fig. 5 is a view of a modified form of bracket and stay, a portion of the latter appearing in dotted lines.

Referring to the drawing, the

numerals

1 and 2 represent the meeting ends of the conveyer belt, which may be formed of canvas, leather or any other suitable flexible material. Upon the upper surface of the edge of the end 1 and upon the upper surface of the end 2 adjacent its extremity are disposed transverse slats or strips 3 and 4, and disposed in juxtaposition to these slats upon the said respective ends of the belt are other transverse slats or strips 5 and 6. The upper surface of the belt is further provided with intermediate cross slats or strips 7, arranged at suitable intervals apart between the slats 5 and 6. Each of these strips 7 has a flat base to rest squarely against the surface of the belt and is fastened in position by a series o1 U-shaped staples or securing pins 8 extending through the belt from the inner surface thereof and entering the strips. Arranged transversely of the inner surface of the belt in line with each strip 7 is a rod 9 engaged and held by the bight portions of the staples and clamped by the same against the belt, said rod acting as a stay to insure a firm clamping engagement of the strip 7 with the belt and to prevent the staples or fastenings from tearing through the belt under the strain or pressure falling upon the strip. 1n practice, the rod 7 is preferably made 0f metal of such a character as tobe indented by the staples when the latter are driven into the strip, so as to form crimps in said rod by which the latter is held from longitudinal movement and a securer connection between the parts afforded.

Fixed on the slat 3 on the belt end 1 is a series of clips or

coupling brackets

10, 11, 12 and 13, arranged at desired intervals apart and up on the slat 4 of the belt end 2 is fixed a corresponding series of clips or coupling brackets 10a, 11a, 12a, and 13a, corresponding respectively in construction to the first named brackets, but arranged in reverse order thereto. Each clip or coupling bracket has a body portion 14 corresponding in construction except as t0 the details hereinafter mentioned, which is in the form of a loop for the assa'ge Aof the strap upon which the braclliet is fitted, the relative upper and lower Walls of said body portion being provided with registering openings 15 for the passage of a rivet or equivalent fastening 16 to secure the same rigidly to the slats, the rivet also passing through the belt and securing both the slat and bracket thereto. Each bracket is also formed at its rear end to provide a pintle 16 to receive and engage the hooked outer end 17 of a reinforcing strap 18, the straps connected with the bracket on each end of the belt extending rearwardly and longitudinally in contact with the outer surface of the belt and being clamped by the bar 5 or 6, as the case may be, against the surface of the belt, each bar 5 or 6 and the adjacent ends of the straps being rigidly fastened to the belt by rivets or equivalent fastenings 19. of resilient strips of metal, so as to allow ample iieXibility of the ends of the belt While connecting the end slats 3 and 4 with the adjacent slats 5 and 6 to stay and reinforce said slats 3 and 4 against the pulling strain of the take-u means hereinafter described, thus obviating liability of the fastenings connecting said slats 3 and 4 and the brackets to the belt from pulling out under such strain and preventing `undue stretching yof the belt from the samecause. l

AThe brackets 11, 13, 11.a and 138L correspond in'construc'tion, each having an arm2`0 hole-shaped slot '24 and an upturnedear orv free en d provided with anopening25. The brackets 12 and 12a differ in construction from the other brackets to the extent that their pivotedarms 26 areeach formedA at its outer end with an 'upturned ear or portion having an opening 27 and provided at one side with'an upturned guide ear 28 having a transverse opening therein. i A

As before described, the two series of brackets upon the

ends

1 and 2 of the `belt arearranged in reverse order, the brackets 10, 11, l2 and 13 upon the end 1 extending in onedirection acrossithe belt along the bar y3, while the corres ending brackets 10a, 113,12 .e and 13a upon te end 2 extend in the opposite direction across lthe belt'alon the bar 4, which arrangement is employe( for the purpose of connecting the endsr of the belt in a prescribed manner through the use of intermediate connecting cords Vor their equivalent 29 and 30. As clearly shown Fig.` 1, one endof the cord 29 is suitably fastened in the opening 27 of thebracket 12a, thence .eX- tended longitudinally between the belt ends and transversely through the guide passage in the arm of the bracket member 11, the opening 28 in the bracket member 12 and the guide passage in the arm of the bracket 13, "and thence extended longitudinallyfto the bracket 'member 10a, said cord being passed upwardly through the keyhole slot 24 in the arm of said bracket 1-0EL and drawn into the `,contracted portion of said slot, thence passed through the opening 2.5 in said arm and finally connected at its free endI a retainer 31 slidably engaging that portion of the cord extending between ,the brackets These straps may be formed 13 and 10a to admit of adjustment in the length of thecord for the purpose of spacing the ends of the belt a desired distance apart. The ycord 30 on the other hand is fastened at one end in the opening 27 of the pivoted arm of bracket 12, thence extended longitudinally between the ends of the belt and passed through the .guide passage in the plvoted arm of bracket 11, through the opening 28 in the pivoted arm of bracket 12.a and tbfcugb tbe 'guide fpeeeege ,in the riveted cfm cf bracket 13a eed .thence extended beck 4over te .the bracket 10, its free eed being eggeged with seid bracket .in the seme meneer .in which Ythe .eed ef the ccrd 29 cngeged with the bracket ,1D-f* and .finally ccneected et ite extremity with e retainer 32 Sliebly engaging tbet pertce cf the kcern extending between the brackets 133 and 1 to admit of adjustment in the length of said cere fcr ltbe Purpcee Prercuely cXPleieed with reference te the lcord 29. By this. means the ends of the cords 4are respectively Permeecntlr attached ,to ,the riveted erg-1S .cf the'ceuplnge ,12 eed 12a end fastened et their o posite 1ends in the `contracted kortions ,o' the slots ofthe arms l.of the brac7 ets 10 end 10% end Such corde .extended :through the guide portions of the other brackets, thus permitting the respective cords to be adjusted ce te length te regulate the distance between the eedeef the belt b Sim 1y :drewing the cords back into the Aenfarger portions of the slots 2 4 of the brackets 10 and 1Q and adjusting the ,sliding retainers 31 and 32, the Pull uren the ende cf the belt 'frein the longitudinal strain of the belt normtuy holding said cord in the retracted portions .0f the Slots 24 te maintain the cords in edjusted position. A ,coiled contractile spring SSfeXtends longitudinally in line with Ithe center ofthe belt between the portions of the cercle. 29 enel .30 extending trenevercely between the

respective brackets

11 and 12 and 11a and 1 2a and is rovidd at its ,end with guideSl carrying pu eye 34, tbrcugh which guides end ereued which Pulleys the Seid rportions of the cords pass, by which the movable portions of the cords are main, tained nnder a determined pull by the conf .traetile .energy cf the Spring, which thus yieldingly couples the ends of the belt and acts .to take up all slack therein .as well as to permit temporary elongation of the belt Whe-11 eXceSSj Strain felle thereon in the Opere ation thereoft It will be observed that as the ccrde ere guided fer free movement be: tween ytheir ende en easy operation thereof is ,insured in the contraction and expansion of the ccuplng connections, and that the pivoted arms of the brackets also permit proper flap 2a which is ol su'llicient length to cover the coupling connections and extend over upon the belt end l when such portion of the belt forms a part of the upperv stretch thereof, thus making the belt continuous. Adjacent the cross slat 4 this flap is properly cut away to permit the coupling brackets carried by said slat to project under and through the flap.

It will be seen from the foregoing description that my invention provides a coupling connection between the ends oi` the belt which insures ample ilexibility ol' the belt at the points where the ends are connected together, and also operates to maintain the belt taut at all times. The coupling connections are also readilydetachable to permit or" their removal 'for repairs or the substitution ol' new parts when occasion requires, and by the use ol' the straps 18 and their mode ol attachment to the ends oi' the belt, such portions oi the belt are strengthened and relieved ol' a large proportion ol' the pulling strain to avoid liability of loosening or disconnection olI the lastenings ol' the coupling brackets.

li' desired,the body portion o' each bracket may be provided with aT-shaped head 36 i'or connection of the adjacent end or" the strap 18 therewith, as illustrated in Fig. .5, the end ol' the strap being apertured to engage the head in an obvious manner to securely and yet detachably Yl'asten it thereto. Also the straps may be made ol' spring metal strips,strips ol' rawhide or strips oi' any other suitable flexible material.

Having thus Yl'ully described the invention, what is claimed as new is l. A belt provided at its ends with coupling members having pivoted arms, the arms oi' the respective members being provided with retaining and guiding portions, cords engaging said retaining and guiding portions ot' the arms and extending bacl and iorth between the ends ol' the belt, each cord having a permanently retained end and a temporarily fastened adjustable end, and a takeup spring engaging the guided portions oi the cords.

2. A belt provided at its ends with inner and outer cross slats, coupling members engaging the outer cross slats and provided with pivoted arms having guiding and retaining portions, ilexible stays on each end of the belt, said stays being secured at their inner ends with the inner cross slats to the belt and pivotally connected at their outer ends to the coupling members, cords engaging the retaining and guiding portions of the arms and extending back and forth between the ends of the belt, and a take-up spring engaging the guided portions of the cords.

3. A belt provided at its ends with coupling members, each oi' said members having an arm pivotally and detachably connected therewith, the arms of said members being provided with guiding and retaining means, cords engaging said guiding and retaining means and extending bach and forth between the ends ol the belt, each cord having a permanently retained end and a temporarily lastened adjustable end, and a take-up spring engaging the guided portions ci' the cords.

4. A belt provided at its ends with coupling members having pivoted arms, the arms oi' the respective members being provided with retaining and guiding portions, cords engaging said retaining and guide portions o'll the arms and extending baclr and forth between the ends ci' the belt, and a take-up spring engaging the guided portions ol the cords.

5. A belt provided at its ends with cross slats, coupling members engaging said slats, each having an arm pivotally and detachably connected therewith, the arms of said members being provided with guiding and retaining means, cords engaging said retaining and guiding means, and a take-up spring engaging the guided portions of the cords.
