Similar characters of reference are employed in the hereinabove described views, to indicate corresponding parts.

Referring to the drawings, the framework of the machine, in the illustrative embodiment thereof as shown, is formed by spaced apart sta tionary transverse frame members i and 2 at one end thereof, a'similar stationary transverse frame member 3 at the opposite end thereof, and a movable transverse frame member s intermediate said end frame members. The stationary end frame members are joined together by side rails 5. Respectively supported by the stationary frame members I, 2 and 3 are respective transverse frame plates or aprons 5, 7 and 8. Supported by th movable frame member 4 are similar frame plates or aprons 9 and I0. Supported by the frame members I and 2 above their frame plates or aprons 6 and 1 is a fixed horizontal work table I I, and similarly supported by the movable frame member 4 and its frame plates or aprons 9 and I is a work table section I2 which is thus carried by and so as to be movable with said movable frame member 4. At the receiving end of the machine is mounted a table extension I3 which is disposed in the plane of the work table II for communication therewith. Said table extension I3 is supported at its outer end by an additional stationary frame member I4 which includes a transverse frame plate or apron I5.

The main shaft Iii of the machine extends longitudinally thereof beneath the work table parts II, I2 and I3, the same being journaled in bearings I! respectively affixed to frame plate or apron parts of the machine framework. Power may be transmitted to said main shaft it from any suitable source; preferably, however, an electric motor M is provided to serve as a power source. Power is transmitted from the motor M to the input shaft I8 of a reduction gear mechanism I9, and by the latter, through gearing 2%, to said main shaft IS.

A pair of stock strip feed rolls is provided in connection with the work table I! and its extension I3 (see Figs. 1 and 2) These feed rolls comprise a lower roll 2|, the shaft of which is journaled in bearings 22 mounted in connection with the stationary frame member I of the machine framework, and an upper roll 23. The shaft of the upper roll 23 is journaled in a bearing 24 carri'ed by carrier arms 25 which are pivotally connected with supporting means -2 mounted in connection with the stationary frame member of the machine framework. As thus supported, the upper feed roll 23 can be adjusted relative to the lower feed roll 2!, by means of adjusting screw 21, whereby to accommodate the nip of said feed rolls to stock strips of difEeren-t thickness. The means for driving the few rolls 2! and 23 comprises a transverse countershaft 2'8 whichis driven from the input shaft 58 of the reduction gear mechanism I 9 by a chain and sprocket transmis sion '29. The :feed rolls 24 and '23 are driven in opposite directions from the countershaf-t 23 by .a

'chain and sprocket transmission 30 (.see Mounted on the table extension -I-3., adjacent to its outer end, is a stock strip edge beveling or trimming means, in advance of which are moun ed laterally spaced guide members ii-I which lead a stock strip to and for passage through said edge beveling or trimming means, when said stock strip is introduced into the machin for passage therethrough. The edge beveling and trimming means comprises a pair of lateral-lyspaced and opposed carrier plates 32 which respectively border opposite sidesof the path of movement of a stock strip into the machine. Supported by said carrier plates 32 are cutting knives 33, the forward ends of which terminate insharp, chisellike cutting edges which are positioned close to the discharge side of the nip of apair of drive rollers by which the *stock strip is advanced to move its edges into engagement with the cutting knives subject to the edge beveling or trimming action thereof. Said drive rollers comprise lower rollers 34 and an upper roller 35, the shafts of which are journaled in bearings similar to those which journal the shafts of the feed rolls 2| and 23 as above described. The lower drive roller 34 is driven from the shaft of the lower feed roll ZI by sprocket and chain transmission and similarly the upper drive roller 35 is driven from the shaft of the upper feed roll by sprocket and chain transmission 37 (see 2) It will be understood, however, that said drive rollers may be power driven in any other manner found convenient or desirable, the above described power transmission thereto being merely illustrative. Supported from and above the table or:- tension I3 is a transverse frame 3t having bearing arms 39 extending therefrom. Journal-ed in and between said bearing arms is a transverse adjusting shaft 40, to one end of which is amxed a hand wheel 4| by which it can be manipulated. This adjusting shaft 40 is provided with a left hand screw-threaded section and a right hand screw-threaded section. The carrier plates are respectively supported by brackets 42 which are respectively in threaded engagement with the respective left and right hand screw-threaded sections of the adjusting shaft 40, whereby, upon manipulation of the latter, the carrier plates 32 can be adjusted toward and from one another to accommodate their cutting knives 33 for engage-- ment with different widths of stock strips (see Fig. 1).

Mounted on the table extension I3, to extend intermediate the stock strip beveling or trimming means and the feed rolls 2i and 23, is a stock strip guiding means 43, which is laterally adjus able to accommodate stock strips of difierent widths. Said guiding means 43 guides a steel: strip issuing from the beveling or trimming means to the feed rolls '2 I23, so that the same will be engaged by the latter and thereby advanced onto the work table III2 subject to movement by transfer mechanism, to be later described, from one station to another at which various processing operations are performed by mechanisms hereinafter described.

As a stock strip issues from the feed rolls 2 I-23 it is lodged upon the rearward part of the work table II-42, which constitutes a receiving station, in longitudinal extension over the latter, and so as to be held against outward lateral displacement by back stop elements 44 which are fixed upon the work table.

Laterally spaced apart at respective stations between the rearward and forward sides of the work table are various mechanisms by which the stock strips are processed to finally produce finished apparel belt or strap bodies. In the illustrative embodiment .of the machine as shown, first beyond the receiving station is the station at which is located the mechanism "for punching and end shaping the stock strips; next beyond the punching and end shaping station is the station at which is located the mechanism for skiving the stock strips to complete formation of the buckle receiving end of the produced belt or strap; next beyond the skiving station is the station at which is located the mechanism for stamping or imprinting the stock strip with beltor strap size, descriptive or other desired indicia; and beyond the latter station is the belt or strap body discharge station, in connection with which mechanism for embossing .or scoring the .front .face surface of the produced belt or strap may be associated. It willbe understood that the described and shown sequence of .sta-

. tion relationship maybe varied; i. e. the sequential order in which the performance of the several operations involved takes place may be changed, if desired, to give relative precedence of one given operation over another.

The means for punching and end shaping the stock strips, in a preferred form and arrangement thereof as shown more particularly in Figs. 1, 3, 4 and 5, comprises mechanism which is operative upon the rear end portion of a stock strip for shaping and slotting the buckle receiving end of a belt or strap body, this mechanism being mounted in connection with the stationary frame member I, andmechanism operative upon the forward end portion of a stock strip for shaping and punching the free end part of a belt or strap body, the latter mechanism being mounted in connection with the movable frame member 4 in longitudinal alignment with the buckle end shaping and slotting mechanism, subject, by movement of the movable frame member 4, to adjusted spaced relation to the latter mechanism according to length of belt or strap body to be produced, in manner and by means herein subsequently explained.

In Fig. 1 the buckle end shaping and slotting mechanism is generally indicated by the reference character and the free end shaping and punching mechanism is generally indicated by the reference character 5|.

The buckle end shaping and slotting mechanism 50 is best shown in Fig. 3, and comprises a vertically reciprocable carrier frame, generally indicated by the reference character 52 and formed by laterally spaced c-shaped side plates 52' which straddle the outer end of the work table I I. The upper end of said carrier frame 52 is provided with top cross-heads 53 and 53', and its lower end with a bottom cross-head 54, the latter having a dependent slide arm 55 which is slidably supported in a bottom guide member 56 that is mounted on the frame plate or apron 6 of frame member I below the work table II. Mounted on the top end of the frame member I, which projects above the work table I I, is a top guide member 51. Extending upwardly, through the top cross-heads 5353' is an upper slide arm 58 which is slidably supported by the top guide member 51. Affixed to the lower end of the slide arm 58 below the cross-head 53 is a carrier body 59 which carries a tool holder 60. The tool holder (it can be longitudinally adjusted relative to the carrier body 59 by an adjusting screw BI which has swivel connection with the tool holder 60 and which is in threaded connection with a nut piece 6% dependent from an end of the carrier body 59. Mounted on the tool holder St is a suitably shaped cutter mernher or blade 63 which operates to shape the extremity of the buckle attachment end of the belt or strap body to be produced. Also mounted on the tool holder fill is a slotting punch M which operates to form the buckle attachment slot in the belt or strap body to be produced. The carrier body 59 with the tool holder fill can be vertically adjusted within the carrier frame 52, whereby to predetermine the spacing of the cut ting blade 63 and slotting punch 54 relative to the work table II according to the stroke amplitude of carrier frame reciprocation. To this end, adjusting screws -65 are threaded through the cross-head 53 and are operative to engage the carrier body 59 so as to vertically adjust its position and thereby the tool holder and tools in the carrier frame.

Carried by the tool holder '60 is a punch scrap discharge duct 66 with which the slotting punch 64 communicates so that punch scrap will pass from the interior of the latter into said discharge duct; injector means 6'! being connected with the duct for delivering compressed air thereinto whereby to convey the punch scrap therethrough to a suitable point of discharge and collection.

The means for effecting properly timed reciprocation of the carrier frame 52, and the tools operated thereby, comprises a lay shaft 58 which extends longitudinally beneath the table parts II and I2. This lay shaft is journaled in bearings 69 respectively mounted on frame plate or apron parts of the machine framework. The lay shaft 68 is driven from the main shaft I6 by means of a drive gear Ill on the latter which meshes with a driven gear II on the former. Journaled in the bottom cross-bar 54 of the carrier frame 52 is an anti-friction roller 12, and fixed on the lay shaft 68 is an actuating 'cam I3 which engages said roller 12, and which functions to reciprocate the carrier frame 52 and the tools carried thereby. Spring means M operates to cause the carrier frame and its roller 12 to follow the cam I3, thus assuring operative reciprocation of said carrier frame and the tools carried thereby.

The mechanism 5| for shaping and punching the free end portion of the producing belt or strap bodies, which mechanism is longitudinally aligned with the above described buckle end shaping and slotting mechanism, and adapted to be simultaneously operated with the latter at the same table station, is also best shown in Fig. 3, and likewise comprises a vertically reciprocable carrier frame generally indicated by the reference character I5 and formed by laterally spaced C-shaped side plates I5 which straddle the outer end of the work table section I2 associated with the movable frame member 4. The upper end of carrier frame 15 is provided with top cross-heads l6 and I6, and its lower end with. a bottom cross-head H, the latter having a dependent side arm it which is slidably supported in a bottom guide member 79 that is mounted on a frame plate or apron IQ of the movable frame member 4 below the work table section I2. Mounted on the top end of the movable frame member 4, which pro ,iects above the work table section I2, is top guide member 80. Extending upwardly through the top cross-heads I6 and 76' is an upper slide arm 8| which is slidably supported by said top guide member 80. Afiixed to the lower end of said slide arm 8| below the cross-head U5 is a carrier body 82 which carries a tool holder 83. The tool holder 83 can be longitudinally adjusted relative to the carrier body 82 by an adjusting screw 84 which has a swivel connection with the tool holder 83 and which is in threaded connection with a nut piece 85 dependent from an end of the carrier body 82. Mounted on the tool holder 83 is a suitably shaped cutter member or blade 86 which operates to point the extremity of the free end portion of the belt or strap body to be produced. Also mounted on the tool holder 83 are a plurality of longitudinally spaced hole punches 31 which operate to form buckle tongue engageable perforations or holes in the free end portion of the belt or strap body to be produced. The carrier body 82 can "be vertically adjusted within the carrier frame'I5, whereby to predetermine the spacing ofthe cutting blade 85 thei e h'h 'leeif serene .5 lie e 1 e i retir lto hehee h e i 3' a so to yertica llyladjustits position 'an'cl 92 1 ehe t eleih he eerh Carried by the tool holder 83 is a punch scrap dis ha g vd s wi h whi h h p heh s' 'e' l e iv t h 'QheC Hfee iihJQ h ar frame e r ethe he e lfie he 5 h he Teller 9 t fe low th 19 t u eee r timed 'h retir ee h eeehh; 9 s i earlier hem f and theciittinbl ad'hfi and meanes carried thereby.

Said skiving means is generally indicated in Fig. 1 by the reference character I20 and the stock strip clamping means which is cooperative therewith by the reference character I2I.

The skiving means is best shown in Figs. 6 and 7, and comprises a slideway member I22 which extends outwardly from the work table I I in the plane thereof. Longitudinally slidable in said slideway member is a slide plate I23. Carried by the slide plate, to overhang a transverse opening I24 with which its inner end portion is provided, is a skiving blade I25, the latter being disposed with its cutting edge directed toward the outer end of the slide plate. Mounted in upstanding bearings I 26 in connection with the outer end portion of the slide plate I23 is a bell-crank lever comprising a substantially vertical arm I21, which extends downwardly through an opening I28 in the outer end portion of the slide plate I23, and a substantially horizontal arm I29 which extends inwardly over the slide plate I23 to overhang the skiving blade I25 and the bordering opening I24 in said slide plate. Mounted on the free inner end of said bell-crank arm I29 is a pressure roller I30. The outer end portion of the slide plate I23 is provided with longitudinally spaced dependent lugs I3I and I32 in which are respectively mounted adjustable stop screws I33 and I34 to oppose opposite sides or faces of the bell-crank arm I2'I which depends therebetween.

The means for reciprocating the slide plate I23 to effect the skiving operation comprises the following mechanism. Journaled in bearings I35 mounted on frame plates or aprons of the machine framework is another longitudinal lay shaft'I36, the same being driven from the gear II on the lay shaft 68 by a driven gear I37 which is fixed on said lay shaft I36. Driven by said lay shaft I36 is a cam I38 which effects timed operation of a lever means I39. Said lever means I39 is pivoted on a bracket arm I40 that extends from the frame plate or apron I on the frame member 2 of the machine framework. A connecting rod or link MI is connected between the lever means I39 and the arm I2! of the bell-crank lever carried by the slide plate I23. Pull spring means I42 causes the lever means I39 to follow the actuating cam I38.

Means is provided for clamping a stock strip to the work table against longitudinal movement Said clamping during the skiving operation. means may be varied in form and location. One illustrative arrangement and location thereof, as shown, is generally indicated by the reference character I21, and is best shown in Fig. 6, the same comprising a carrier frame I44 which is formed by laterally spaced side plates I44 which straddle the outer end of the work table section I2. The upper end of this carrier frame is provided with a cross-head I45. Slidably extending upwardly through said cross-head I45 is a slide arm I46, the upper free end portion of which is slidably supported by a guide member I4! that is mounted on the top end of the movable frame member 4 which projects above the work table'section I2. Fixed on the lower end of'said slide arm I46 is a clamp plate I48 that is opposed to the surface of said work table section 42. A compression spring I49 is mounted around the lower end portion of the slide arm I46 intermediate the cross-head I and said clamp plate I48, and is operative to yieldably cushion the clamp plate in its normally stopped position as determined by a stop collar I50 that is fixed on the upper end portion of the slide arm I46 to normally abut the upper end of said cross-head I45. The lower end of the carrier frame I44 is provided with a bottom cross-head 45E, the same having a dependent slide arm I52 which is slidably supported in a, bottom guide member I53 that is mounted on a frame plate or apron of the movable frame member 4 below the work table section I2.

The means for effecting properly timed reciprocation of the carriage frame I44 and clamp means carried thereby comprises an actuating cam I54 that is fixed on the lay shaft I36. This cam I54 engages an anti-friction roller I55 which is mounted in connection with the bottom cross-head I5I. Spring means I56 operates to cause the carrier frame I44 and said roller I55 to follow the cam I54, thus assuring operative reciprocation of the carrier frame and clamp means.

In the operation of the skiving means, after a stock strip has been advanced over the work table so as to be aligned with the skiving device and cooperative clamp means, the cam, I54 is timed to lower the carrier frame I44, whereby to bring the spring cushioned clamp plate E48 down upon the underlying stock strip, thus clamping the latter to the work table against longitudinal shift under the pull of the actuated skiving device. The stock strip being thus clamped to the work table, the cam I38 is timed to cause an outward working movement of the slide plate I23 and skiving blade I25 carried thereby. Preparatory to this working movement, the cam actuated outward thrust of the link I4I against the arm I2I of the bell-crank lever carried by the slide plate I23, causes this arm I21 to swing outward against the stop screw i35, thereby down swinging the horizontal bell-crank lever arm I29 so as to force the pressure roller 430 down upon the underlying stock strip, whereby to press the underside of the latter against the cutting edge of the skiving blade I25 (see Fig. 7). This having taken place, continued outward thrust of the link MI is transmitted, through the engaged bell-crank lever arm I21 and stop screw I 33, to the slide plate I23, so as to slide the latter outwardly on the slideway member H2, and thereby to cause the skiving blade I25 to shave or skive the underface of the engaged portion of the stock strip, whereby to thin such portion. Upon completion of the skiving stroke, the actuating cam I54 operates to first up swing the bell-crank lever so as to lift the pressure roller I30 away from the stock strip, and thereupon to retract the slide plate and skiving blade to normal initial position, and to uplift the carrier frame I44 so as to release the stock strip from the clamp plate I48.

Located at a next succeeding station after that at which the skiving means is stationed is the means for stamping or imprinting a belt or strap body being produced with size, descriptive or other desired indicia. This stamping means is generally indicated in Fig. 1 by the reference character I60, and is shown more in detail in Fig. 8. Mounted in connection with the underside of the work table I I is a printing mechanism i6I, the printing face I62 of which projects through an opening I62 in said work table II, so as to lie substantially in the plane of the stock 11- strip: supporting top surface of said work table.

Each propelling device (see Figs; 9 to 13' inclusivei comprises a stationary; guide-structure formed by" upstanding;- endwiseopen,- guide frames ZUIwvliich are affixed to=the -work-table respectively at v the receiving side and; the dis char-ge side" thereof. Provided in the%'sides 10f the-guide frames 20 I are internal slideWay-ledges 202, .suitably spaced. above the work table surface in plane "p arallel thereto; for thesupport of reciprocable impeller -means. Affixed toan'd ex tending between'the-guide frames 21H are laterallyrspaced-side members 2 03; the space inter: mediate thereorproviding a 'slidewaypassage-2ll4 in which" the-impeller means reciprocates The impeller means comprises a-slidemember formed byrlater'ally spacedapart slide-bars -2 05; secured together by intermediate spacer members 206;

3 The slide bars 295 are slidably supported by the heretofore mentioned slideway ledges 292 with which the guide frames 29! are provided. Pivotally connected with and between the slide bars 295 are a plurality of bifurcate impeller members 291, the same being longitudinally spaced at suitable intervals along the slide member formed by said slide bars. Said impeller members 29? terminate at their lower free end portions in suitably shaped push fingers 298. Longitudinally movable between the slide bars 295 of the slide member is a tractor bar 299 which is straddled by the bifurcate impeller members 291, and to which the latter are also pivotally connected, subject to forward and back swin about the pivotal connections thereof to the slide member. Said tractor bar 299 has a lost motion coupled connection with the slide member that is provided by a stop member 219 which is afiixed to the tractor bar, and which is provided with longitudinally spaced forward and rearward stop lugs 2H and M2 adapted to be engageable with a coupling cross-pin 253 that is affixed to and between the slide bars 205 of the slide member. The forward end portion of the tractor bar 299 extends freely beyond the forward end of the slide member and outwardly beyond the discharge side of the work table, and is adapted to be connected with means, to be presently described, for causing timed operative reciprocation of the propelling device.

Mean is provided for varying the stroke of the propelling device, whereby to accommodate the same to stock strips of various widths. For narrow stock strips the propelling stroke, operative to transfer the stock strip from station to station, must be somewhat longer than would be required for transfer of wider stock strips, and consequently the stroke must be adjusted so that in either case the termination of the forward propelling phase thereof will dispose the stock strip in centrally aligned relation to the processing mechanisms at the respective station locations. The means for varying the stroke of the propelling device to such end comprises an adjustable stop member 2M which is threaded on a screw-threaded carrier shank 2l5; the latter projecting longitudinally outward from the rear end of the slide member of the propelling device. In operation, when properly adjusted on the carrier shank 2l5, the stop member 2M will abut the rear guide frame 29l so as to arrest the stock strip advancing stroke of the propelling device at a required predetermined point. The adjusted position of the stop member 2 M for different widths of stock strips may be indicated by a suitably graduated scale provided on the periphery of said stop member so as to be readable with reference to a fixed indicator pointer 216 mounted on the rear guide frame 26! (see Figs. 9 and 10).

To'cause properly timed reciprocation of the stock strip propelling devices, a rock-shaft 2|! is journaled in bearing brackets 2H8, which project from the machine framework, to extend longitudinally along said machine framework adjacent to the discharge side of the machine. Mounted on this rock-shaft 211, so as to be oscillated thereby, are lever arms 2? adapted to be respectively coupled with the freely projecting end of the tractor bars 299 of the respective propelling devices. Each tractor bar 299 is coupled to a corresponding lever arm 219 by a yieldable coupling connection comprising a knuckle member 229 that is pivotally connected to the end of the tractor bar. Extending axially outward from said knuckle member 229 is a tail rod 22! which slidably extends through a coupling collar 222 to which the lever arm 2|9 is pivotally connected. A compression spring 223 is mounted around the tail rod 22! between the coupling collar 222 and a stop nut7224 with which the end of the tail rod is provided. The yieldable coupling connection thus provided will accommodate the uniform oscillatory movemen u 0f the lever arm M9 to any variation in the stroke for which the propelling device is adjusted by the setting of the stop member 214. The means for producing properly timed oscillation of the rockshaft 2!? and its lever arms 2i9 comprises a cam 229 which is mounted on the outer end of the shaft E92 which is driven by the gearing I93 from the countershaft I85. Fixed on the rockshaft 2:! is a crank-arm 226 which is provided with an anti-friction roller 22'! adapted to be engaged by the cam 225. A pull spring 228 is anchored to the machine framework and connected with a lever arm 229 fixed on th rockshaft 2H, whereby to cause the crank-arm 226 and its anti-friction roller 22! to follow the cam 225.

In the operation of each propelling device, the same, in its retracted normal initial position, is disposed to engage stock strips S which are supported by the work table so as to be located at the receiving and advance stations. After the processing operations, which are simultaneously performed at advance stations, are completed, the means by which the propelling device is actuated is timed to effect an advance stroke of said propelling device. Such advance stroke is produced by outward swing of the lever arm 219 by which the propelling device is reciprocated. As outward swing of the lever arm 2 I9 is initiated, the first effect is to induce an initial independent longitudinal movement of the tractor bar 299 which is permitted by the above described lost motion connection of said tractor bar with the slide bars 295 of the slide member. The effect of this initial movement of the tractor bar 209 is to down swing the impeller members 201, whereby to engage their push fingers 298 behind the stock strips S. This having occurred, the rearward stop lug 212 of the lost motion coupling connection engages the cross-pin 2| 3 of the slide member, whereupon said slide member accompanies continued advancing movement of the tractor bar 299, and consequently causes the impeller members 201 to slide the stock strips S over the work table from one station to a next'succeeding station (see Fig. 9). To hold the stock strips S against displacement from aligned relation to processing mechanisms located at stations to which the stock strips have been thus delivered, bowed detent spring members 239, which are affixed to the under edges of the side members 293 of the guide structure in which the slide member moves, tensionally bear upon the delivered stock strips S, whereby to frictionally bind the same to the work table surface (see Figs. 9 and 10). While the processing mechanisms at the advance stations are performing their functions, the means by which the propelling device is actuated is timed to effeet the return or recovery stroke of the propelling mechanism, which is effected by inward swing of the lever arm M9 by which the propelling device is reciprocated. As inward swing of the lever arm is initiated, the-first effect is to induce an initial inward longitudinal movement of the tractor bar 299, which functions to 1 6 sie d rine ql i q y s he' r mu 1131, wherebythe in ieedingjofa stool: strip onto the work table for deposit at the receiving stat fth'eredf is fgiqqompanied by the scoring' or a i Qt beta-fie the istoqk t ip such v the disoharge r 1 cooperative with the :disc ir station of the work table would be ar a h preferablyresilient faee type.
