BELT TIGHTENING AN D CUTTING DEVICE.

Application filled November 27, 1922. Serial No. 603,6QQ,

To all whom it may concern I Be it'known that I, WALTER S. LAKE, a citizen of the United States, andresident of Kansas City, Jackson County, State of-Mis- -souri, have invented a certain new and useful Improvement in Belt 'llghtening and Cutting Devices, of which the following is a complete specification. This invention relates to belt tightening, cutting and fastening devices and has for its object to produce a device of the character mentioned which is so constructed and ar-, ranged that thebelt may be properly tightcned, cut with an absolutely square joint and then .abutted against the ot er end of the belt and the two ends secured together by any suitable or preferred lacing;\all of theseoperations being carried out without removing the belt from operative positibn'. v

A further object is to producea device of construction for convenience of and which is construction. I

J With the objects namedin yiew the invention consists in certain novel and useful features of construction and organization of parts as hereinafter described and in order that it may be fully understood, reference is to be had to the accompanying portability; also of simple and. inexpensive I drawings, in which Figure 1 is a top plan view of the device;

Figure 2 is a side view of the same;

Figure 3 is a section 0 the line III-I I I of Figure 2; p Figure i is a section on the line Il -*1" of Fi 'ure 3;

Figure 5 is a view similar to that of Fig ure 3, but illustrates the device as it will ap- Jearwhen a belt lacing of a preferred type has been placed in the device;

Figure 6 is an end view of a common and a well known type of belt lacing; and

- ferred to.

Figure? is a top plan view of anew of belt lacing as it will appear when engaged with a belt.

In the'said drawings, where like reference characters identify corresponding parts in all of the figures, 1 illustrates the base mem: ber of the device, said base member being" formed with a longitudinal slot or opening 2 for the reception of a knife, hereinafter re- Projecting at ri ht angles the base and. at one end thereo is a handle 3 for use in positioning thedevice, and at theother end,

. i I r V '9 and equipped at its and claimed type i the base member is formed with an upwardly projecting standard 4 terminating in a forwardly extending arm 5 parallel to and above the base and ending at a point about midway the length of the base. v 3

The standard 4 is also formed with a air of arms 6 and 7 projecting in 0 posits directions and curving around paral el to the base and at opposite sides and above the plane of the same.

The base 1 is formed at one side with an extension or abutment portion 8 underlying the end of the arm 7.; At its'op'posite side, the base 1 is formed with a pair of outwardly projecting ears 9, between which is secured a roughened feed roller 10'keyed on an operating shaft 11, journaled in the ears outer end in close proximity to the handle 3 with an operating knob 12, whereby said. roller 10 may lie rotated.

Secured in the slot 2 of the base is a beltcutting knife '13 formed with-air operating ear 14. The ear will at all tim s, project above the base through the slot and the body of the knife is formed near; its ends with a pair of semi-circular slots 15 for engagement with a pair of pins loispanning the slot 2. In this connection by reference to Figure 4, it will be noted that-when the knife is in its elevated position, the pins 16 will beengaged in a part of the slots. which is substantially at right an Ice to the vertical. It willtherefore. be evident that direct downward pressure on the knife will-be re- 1n position. W'hen. it is desired to lower the knife a downward and rearward other arm 6 is engaged by a clamping sci'ew 20 provided with an operating, ikfn'ob 21 at its upper end. Swiveled 'on the'flower, end of the screw 20 is an invertegjU-shaped bracket 22 between the arms of '-,-whi(lh is journaled a roller 23 in length substantially equal .to the length of the corrugated roller 10 and. adapted to clamp the belt 13 tightly -movement is imparted to it by the operator teeth, said clamping foot be'ng adapted to clamp one end of abeltB d' an upon the extension, 8 of the base 1. he

down upon the feed roller 10, as will be describethiliereinbelow. "-In order to maintain the roller 10 in any predetermined position against'tl e contracting tendency of the belt.

a ratchet pinion 16) is keyed on theshai't ll adjacent one of the earsi), and pivoted on one of said ears 9 is a gravity-pawl 10* in engagement with the ratchet;

T he extremity of the arm 5 i's-engaged by a clamping screw 24 carrying at its lower end a swiveled bracket 25 to which is seecured afpair of clamping bars 26 and 27 spaced slightlyapart to provide a knifereceiving'slot 28 and of substantially the same length "as the base I; said bars 26 and 27 being secured together at their ends by a pair of cross straps 2!).

1 the bars; and 27 against rotation, the

rear strap .29 is notched to coincide with the slot 28 and received within said notch and'slot is'a guide tongue 30 formed on the front-faceuot-the standard 4 (see Figure 4).

Keyed to the upperend of the screw 24 is an operating-Wheel 31 formed with a serlcs of ratchet teeth 32. and provided also with a a plurality of straight sided teeth 33. The wheel 31 is received within thebi'fureatcd cnd of an operating handle 34 loosely jour naled on the screw 24',and mounted between said bifurcated arms is adouble acting dog 35p1voted'fo'r operation on a pint-36 formed at'its upper endwith a projecting portion 37 for afpurpose'w'hich will hereinafter. appear. ,b'ecured-, in the handle and spaced 'slightlyfrom the'pin'37 isa Second pin 38 'formed with a projeetingkhead. The parts normally stand in the position shown in Figure 1, the dogheing retained-in the position shown by means of a sprii g'flf) abutting at its rear end agai-nst 'the pin '38, in which position-the partsa're ready" to impartdown-' wardmovement to the clamping bars 26 and 27. Then it is desired to rotate the screw 24 inth opposite dire .-tion for the purpose I of elevating, the ha 4 end of tliespringtihtjs disengaged from the 26 and 27,. the free pin 38 amliis-engaged with the pin 516.

'This action reverses the. tendency of the springeandcauses.the other end of the dog to be depressed for engagement with any of the straight edged teeth i lf'i', as will be readi l v understood;

For convenience in maintaining" lacing devices of various kinds in position pending their insertion into the extremitics of a bolt, the following devlces are provided:

fipann-in ;the slot 28'and adapted for slid.-'

ing longitudinally on-bars 26-27 and rest 'ing thereon are a pair of plan-s40; each forinedwitlna tongue 41=depending through the slot 28,;said tongues. being-formed attheir lowerie'ndsw th flanges42 respectively 'i'acing toward,ieach other; It willgbe evi" dent that ethos tianges 42- are adapted to I'QCQIVQ; between themselves andthe faces of In order to hold' ccived within the slot 28.

fing -12, for example, that illustrated in Fig ure (3; I In order to secure the members 40 in position, they are pivoted near their rear. edges to av pair of securing clips 423 bent downwardly and engaged with the underface of the bars 26 and 27, as willhe readily understood. The men'ihers to are ordinarily slid to the extreme limits of their movement so as to be out of the way, as will be set forth inthe description of the operation of the deviuu'and when the kuiil'c is elevated and the bars 26 and :27 are lowered the plates 40 will be pivoted upwardly, the parts 41 and -12 being received Within the slot 28, through contact [with the edge of the knife.

In order-to securely maintain in position a belt lacing 42 formed of two members its end is adapted to intersect the slot 28 between the pair of bars 26 and 27.

The hinge portion of the, type of lacing mentioned is inserted inv the-slot as (see Figure 5) and the lacing is securely rctained in position under the pressure imposed on it by the thumb screw 44.

In the operation of the device one end of the belt is inserted into position with its end flush with the slot 2 of the base and is clamped tightly in such position through the pressure in'iposcd on it hy tbe clamping foot 19 of the screw 17, against the cxtcnsion 8 of the base.

The-other end of the belt is inserted between the rollers 10 and 23, and clamped tightly between said'rollers by operation of the clamp screw 20. The feed roller is now rotated through its knob l2, thus stretching the belt and causing the adjusted end to overlap the other end, as shown in Fig ure 3, the pawl and ratchet mechanism 10* and 10* holding the adjusted end firmly in the position above referred to.

The knife is now elevated through application of forward and upward pressure on its ear 14;, and when in fully elevated posi tion projects above the end of the belt which overlies the extension 8 and underlies the overlai iping end of the belt; (see Figure 3?). The clamping screw 24 is now rotated by means of its handle 34, the dog 35 engaging the teeth 32, and the clamping bars 26 and 27 exert clamping pressure on the ,belt at opposite sides of the knife, causing the knife to impinge on the belt with a shearing action and severing the extremity otsaid belt accuratelyand smoothly, the knife being rclrcliniinary to the downward movement of the bars iii and 27. the lacing supports 40 aren'iovcd to the opposite ends of the slot 29, and upon downward movement of said barsfthe tongues I lit!
