Application filed November 18, 1911. Serial No. 660,981.

G. WARD, a residing at in the county of Tucker, State of West Virginia, have invented certain new and useful Improvements in Belt-Cutting Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apper tains to make and use the same.

This invention relates to belt cutting machines.

longitudinally of the base and operated in any adjusted position. j j

A still further object of the invention resides in the provision of a belt cutting machine which includes a base, a cutting mechanism supported upon the base and means for holding a belt upon the base beneath the cutting mechanism, said belt holding means being adjustable longitudinally of the base and relatively to the cutting mechanism.

71th the above and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claims.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the several views, and in which Figure 1 is a plan View of the invention; Fig. 2, a side elevation thereof; Fig. 3, a view similar to Fig. 2 looking at the oppo site side of the device; Fig.4, an end view of the invention; Fig. 5, a section taken on the line 5-5 of Fig. 1; Fig. 6, a section taken on the line 6-6 of Fig. 1, and Figs. 7 8 and 9 are detail perspective views illustrating the various forms of tools employed in addition to the cutting blade which trims and squares the end of the belt.

Referring to the drawings the machine 1s shown as comprising a base 10 the upper side of which has embedded therein a bed plate 11. Secured to one side edge of the base 10 are inner and outer bars 12 and 13 respectively, the end of the bar 13 terminating short of the ends of the base 10. The upper ends of adjacent faces of the bars 12 and 13 are curved outwardly to produce a longitudinally extending cutting groove 14 for cooperation with a cutting blade to be hereinafter referred to.

Disposed at each end of the base 10 are vertical'standards 16 and 17 each of which is shown as comprising three separate plates connected together side to side. The lower end of the central plate of each of the

standards

16 and 17 terminates short of the lower ends of thelimiting plates of said standards thereby forming a space between the limiting plates which receives the bar 12. The lower end of the outer limiting plates of the

standards

16 and 17 are bent outwardly as at 18 and 19. Mounted on the outwardly bent'lower end 19 is a lug 20 in which is slidably mounted the spring bolt 21 which engages through registering openings in the limiting plates of the standard 17 and the bar 12 to secure said standard to the bar 12. A lag bolt 22 is engaged through the limiting plates of the standard 16 and through the bar 12 to likewise secure said standard 16 to the bar 12. The

standards

16 and 17 are connected to the adjacent ends of the base 10 by means of braces 23 and 24 respectively, said braces being detachably engaged to the base and standards so that by disengagement of same and the disengagement of the lag bolt 22 and spring bolt 21 the

standards

16 and 17 may be readily removed from the bar 12.

Secured to the outer sides of the standards are spaced parallel plates 21, while another plate 25 corresponding in position to the uppermost plate 2 1 is secured against the inner sides of the

standards

16 and 17. Disposed between the

plates

24 and 25 is a head A which includes

vertical members

26 and 27 each of which is formed of three sep arate plates secured together side to side. The upper ends of the

members

26 and 27 are connected by parallel spaced plates 28 and29.

Slidably mounted in the head A is a cut-r loweredges of the plates ,31 and32. The

cam endof thelever 34 is so shaped and positioned that when the free end...of said lever is depressedsaidcamend will cooperate with the inner edge of the portion the U-shaped plate 30 which connects the arms of said plate so as to force the platedow u wardly and impart the cutting stroke to the cutter 33. Whenthefree end of the lever 34 is elevated the pin 35 willcooperate with the walls of the recesses 36 sofas tolift the plate 30 and cutter 33. Disposedagainst the outer faces of the plates 24 are barsi37,

while bars 38 are disposed against the outer face of the plate 25, Thesebars 3.7 and .38 are connected respectively to the

members

26 and 27 by meansof bolts 39. By this construction it will be apparent that the head A and cutting mechanism B are slidably supported above 'the base v.10 by the

plates

24 and 25 so that said head and cuttin mechanism can be adjusted longitudinally of the base as will be obvious.

Secured to the end of the head A adjacent the standard 16 is a pivoted latch 40 provided with recesses 41 adapted to engage over the upper end of the standard l6l so as to lock the head A and cutting mechanism B in different adjustments.

The side of the base 10 remote from the bar 12 is provided with a groove 42 in which is slidably mounted a bar 43 formed of a pair of sectionsarranged sideto side. The end of this bar 43 adjacent the standard 17 is provided with a lateralextension 44 upon which is mounted a plate 45 which partially rests upon the top of the base 10 and disposed at right angles to the cutter 33. The outer edge of the plate 45isprovided with a reces 46 in which is engaged the bight portion of a U-shaped plate 47. The lower arm of this U-shaped plate 4"!v is suitably secured to the lateral extension 44, while the upper arm of said plate is bifurcated and has pivoted thereon a clamping lever 48,for cooperation with the lower arm of said plate.

Projecting laterally from the

standards

16 and 17 are rods 49 and 50 respectively. Journaled on the rod 49 is a lever 51 while an arm 52 is journaled on the rod 50. A clamping link 53 has one end pivotally connected to the free end of the arm 52 and its other end pivotally connected to one end of the lever 51. By this construction it will be apparent that, upon operating the lever 51 the clamping link 53 may bemoved towardand away from the base 10, the movement of said link toward the base serving to clamp a belt disposed upon the base against movement. In this connection 'it will. also be noted thatiwhen a belt is disposed upon the base 10 it will lie between the arms of the plate 47 so that the lever 48 can be operated to clamprthe belt to the i plate 47, WVhen belt is so clamped the link 53 may be released and the belt adjust- 1 ed longitudinallyof thebaselO by sliding .the bar 43 in: the groove 42. After the belt is properly adjusted-byjthis means the link institution of a cutting-' operation. Projecting laterally fromthe plate .30. in the same horizontal plane, are studs 54 over 53 is returned; to clamping position for the which are adapted-( o, be engaged difierent forms of tools such as are shown in Fig.7..

Also. projecting laterallyfiomrthe plate 30 above. each of the studs, .54 are studs 55 in which latter are mounted: respectively binding screws 56 through the instrumentality of.

which. the toolsmounted on the studs '54 are a locked again st disengagementirom the latter. An angle bracket 57 issecured to the inner side otthe standardglfi for adjustment longitudinally of thebase. 1 One arm of this bracket extends transversely of the base and.

is adapted to cooperate with theplate45rinsquaring the work placed upon the base 10.

rality of slots 58 which are'adapted to coop.- erate withthe knives of the tool 59 for the purpose of forming slits in the belt at the same time the edge ofthe belt is trimmedby the cutter, such slitsbeing adapted toireceive the lacing usually-employed in securing the ends of the belt together. The bed plate 11 is also provided avith'a boss' 60 which is adapted to cooperate with the tool6l for the purpose of making. a small opening through the belt without taking any material from the latter. The tool indicated at 62 is adapt spaced arms mutually connected at. their lower ends, parallel-. plates connecting the upper .ends of said arms a lever pivoted-on said head and extending between said paral- 1 lel plates, a cam face on the inner end of.

said lever adapted" when theilever is moved 1 in one direction totcotiperate with the inner. edge of saldmutual connection to force the 100 The bed plate 11 is provided with "a plucutter carrier downwardly, and a transverse pin carried by said lever cooperating with the walls of recessesiformed in the lower edges of said parallel arms when the lever is moved in the opposite direction to elevate said cutter carrier.

2. In a belt cutting machine the combination of a base, a cutting mechanism mounted on said base for adjustment longitudinally thereof, means for squaring the work on the base with respect to the cutting mechanism, a pair of rods extending transversely of the base, a lever pivoted on one of said rods an arm pivoted on the other rod, and a link having one end pivotally connected with said arm and its other arm pivotally connected with said lever whereby the oscillation of said lever will move said link to and from the base in substantial parallelism to the latter.

In testimony whereof, I aifix my signature, in presence of two witnesses.
