- the machine of the present invention is designed for the purpose of automatically feeding a section or sheet metal to knives or cutters which successively sever from the edge of the sheet a series of metal strips, which are thereafter fed downwardly to a crimping blade which folds the metal strips in, such a way to produce a grooved or channeled strip which is thereafter used for the purpose of binding or edging a picture, calendar or the like.
- Tie machine is an improvement on that shown ⁇ 111C described in Patent No. 864,34e9 issued August 27, 1907, to Frederick William Yager, and in general design and con struction the present machine follows quite closely the machine of the patent above referred to.

- Fig. 7 is a sectional view taken through the gear and sprockets of Fig. 6; and
- Fig. 8 is a detail of the reciprocating cutter frame partly broken away.
- the machine as a whole is mounted upon a frame which comprises end standards 1010, each comprising front legs 11 and rear legs 12, an upper cross rail 13 and a lower cross rail 15%, and an upwardly extending supporting arm 15.
- the ends of the frame are'connected by a lower transverse beam 16; and the arms 15, which extend obliquely rearwardly from the upper portion of the frame, afford a mounting for a diagonally disposed feeding table 17, upon which rests a wedge shaped platform 18 which serves as a support upon which the metal blank A is rested.
- the ends of the frame are further provided with diagonally disposed forwardly extending arms 19 which furnish guides for the support and reciprocation of a clamping plate 20 and a movable cutter bar 21, which latter co-acts with a fixed'cutter bar 22 securedto the lower edge of the feeding table 17, which cutter bars present their proxin'iate or cutting edges to the same intermediate plane, so. that the movable bar may slip past the edge of the fixed bar and sever from the metal blank so much there of as protrudes beyond the cutting plane.
- the down feeding of the metal blank is arrested by the provision of a bank of stop fingers 23, some of which are shown in Figs. 4 and 5.
- the fingers 23 are disposed at substantially right angles to the plane of the feeding platform, and each finger at its tip end is provided with a. notch 2a which receives the lower edge of the metal blank.
- Each linger on its lower edge near its center is provided with a notch 25 at which point the finger is fulcrumed upon the up per edge of an angle bar 26, which is carried by a pair of strap bars 27 which also serve to. support a rear angle bar 28, which bar is provided inits front flange with a series of guide slots 29 within which the rear lower ends of the fingers are guided.
- This arrangement furnishes a frame for the entire bank of stop fingers, which frame is completed by the provision of an upper bridge bar 30 which overlies the rear ends of the fingers and is held in spaced relation to the angle bar 28 by the provision of spacer bolts 31.
- Each of the lingers atits rear end is undercutto afford a shoulder 32 which is impelled upwardly by a coil spring 33 which tends to lift the rear end of the linger, and this tendency is resisted by the provision of an adjusting screw 3% which bears against the upper side of the finger. lhe arrangement is such that the fingers can be individually adjusted by turning the adjusting screw so as to perfectly align the forward or acting ends of the entire group or bank of fingers.
- the line of movement of the finger frame as a whole is in a direction transverse to the feeding movement of the metal blank, so that after the clamping plate 29 has moved down into clamping contact with the metal sheet, the fingers which theretoforc have supported it may be retracted in prep aration for the advance of the movable cutter bar, with the result that when the pro jecting end of the sheet has been severed, it will fall downwardly without interference from the stop fingers.
- the finger frame is given a substantially straight line movement of reciprocation in an oblique direction by the means of a cross rod 35, upon which the rear ends of the straps 27 are pivoted, which cross bar has its ends enterec through a pair of screw eyes 37, which in turn are entered througn a cross bar 38, the ends 88 of which are forwardly bent or turned and secured to the inner faces of a pair of rearwardly e3:- tending arms 39 of a slide frame of U- shaped fori'nation, which is provided with a cross head 40, which connects the two side arms and bridges the space between the end fingers of the machine.
- Each arm of the slide frame is guided between a pair of guide bars il secured to the inner face of the prokimate end frame of the machine, so that a straight line rcciprocating movement will be imparted to the slide frame as a whole and to the linger frame carried thereby.
- the movement of reciprocation is given by the provision of a pair cf eccentrics 42 carried by a shaft l3, which eccentrics are provided with arms l lwhich are pivoted to the arms of the slide frame.
- the finger frame being freely hinged or pivoted onto the rod 35, must be additionally supported, and such support is afforded by the provision of rollers 4-5 which are mounted upon a shaft 46, each roller bean ing against a bearing plate a? secured to the underface of the finger frame.

MACHINE FOR MAKING METAL BINDING STRIPS.
Application filed. October 16, 1924. Serial No. 743,867.
The machine of the present invention is designed for the purpose of automatically feeding a section or sheet metal to knives or cutters which successively sever from the edge of the sheet a series of metal strips, which are thereafter fed downwardly to a crimping blade which folds the metal strips in, such a way to produce a grooved or channeled strip which is thereafter used for the purpose of binding or edging a picture, calendar or the like.
Tie machine is an improvement on that shown {111C described in Patent No. 864,34e9 issued August 27, 1907, to Frederick William Yager, and in general design and con struction the present machine follows quite closely the machine of the patent above referred to.
The special improvements are directed mainly to the following features:
1. To the mechanism for actuating the stop fin ers which arrest the advance of the metal sheet preparatory to the severance of a strip therefrom by the knives or cutters;
2. To the means provided for adjusting the position of said stop fingers; and
3. To the means for operating the mechanisms which carry the severed strips from the knife to the point where the crimping blade is located.
Other features and from the description of the invention, which consists in the features of construction and combinations of parts hereinafter described and claimed.

Figure 1 is an end elevation of the machine taken from the right hand end of the machine. as viewed from the front;
I 2 is a similar view taken from the left hand end of the machine, as viewed from the front;
Fig. 3 is a sectional elevation of the ma chine loc ing toward the right end thereof;

Fig. 8 is a detail of the reciprocating cutter frame partly broken away.
The machine as a whole is mounted upon a frame which comprises end standards 1010, each comprising front legs 11 and rear legs 12, an upper cross rail 13 and a lower cross rail 15%, and an upwardly extending supporting arm 15. The ends of the frame are'connected by a lower transverse beam 16; and the arms 15, which extend obliquely rearwardly from the upper portion of the frame, afford a mounting for a diagonally disposed feeding table 17, upon which rests a wedge shaped platform 18 which serves as a support upon which the metal blank A is rested. i
The ends of the frame are further provided with diagonally disposed forwardly extending arms 19 which furnish guides for the support and reciprocation of a clamping plate 20 and a movable cutter bar 21, which latter co-acts with a fixed'cutter bar 22 securedto the lower edge of the feeding table 17, which cutter bars present their proxin'iate or cutting edges to the same intermediate plane, so. that the movable bar may slip past the edge of the fixed bar and sever from the metal blank so much there of as protrudes beyond the cutting plane.
The down feeding of the metal blank is arrested by the provision of a bank of stop fingers 23, some of which are shown in Figs. 4 and 5. The fingers 23 are disposed at substantially right angles to the plane of the feeding platform, and each finger at its tip end is provided with a. notch 2a which receives the lower edge of the metal blank.
Each linger on its lower edge near its center is provided with a notch 25 at which point the finger is fulcrumed upon the up per edge of an angle bar 26, which is carried by a pair of strap bars 27 which also serve to. support a rear angle bar 28, which bar is provided inits front flange with a series of guide slots 29 within which the rear lower ends of the fingers are guided. This arrangement furnishes a frame for the entire bank of stop fingers, which frame is completed by the provision of an upper bridge bar 30 which overlies the rear ends of the fingers and is held in spaced relation to the angle bar 28 by the provision of spacer bolts 31.
Each of the lingers atits rear end is undercutto afford a shoulder 32 which is impelled upwardly by a coil spring 33 which tends to lift the rear end of the linger, and this tendency is resisted by the provision of an adjusting screw 3% which bears against the upper side of the finger. lhe arrangement is such that the fingers can be individually adjusted by turning the adjusting screw so as to perfectly align the forward or acting ends of the entire group or bank of fingers.
The line of movement of the finger frame as a whole is in a direction transverse to the feeding movement of the metal blank, so that after the clamping plate 29 has moved down into clamping contact with the metal sheet, the fingers which theretoforc have supported it may be retracted in prep aration for the advance of the movable cutter bar, with the result that when the pro jecting end of the sheet has been severed, it will fall downwardly without interference from the stop fingers.
The finger frame is given a substantially straight line movement of reciprocation in an oblique direction by the means of a cross rod 35, upon which the rear ends of the straps 27 are pivoted, which cross bar has its ends enterec through a pair of screw eyes 37, which in turn are entered througn a cross bar 38, the ends 88 of which are forwardly bent or turned and secured to the inner faces of a pair of rearwardly e3:- tending arms 39 of a slide frame of U- shaped fori'nation, which is provided with a cross head 40, which connects the two side arms and bridges the space between the end fingers of the machine.
Each arm of the slide frame is guided between a pair of guide bars il secured to the inner face of the prokimate end frame of the machine, so that a straight line rcciprocating movement will be imparted to the slide frame as a whole and to the linger frame carried thereby. The movement of reciprocation is given by the provision of a pair cf eccentrics 42 carried by a shaft l3, which eccentrics are provided with arms l lwhich are pivoted to the arms of the slide frame.
The finger frame, being freely hinged or pivoted onto the rod 35, must be additionally supported, and such support is afforded by the provision of rollers 4-5 which are mounted upon a shaft 46, each roller bean ing against a bearing plate a? secured to the underface of the finger frame. The shaft 46 is journaled upon a pair of armsv 48 which are clamped upon a rock shaft it, the arrangement being such that by reel; ing the rock shaft the point of contact of the rollers 4L5 with. the bearing plates 1-? may be shifted toward or away from the pivot rod 35, wnich will have the effect of slightly raising or loweringthe finger frame as a whole, thereby providing a simple and desirable means for shifting the entire bank of stop fingers up or down to the degree required for adjusting the machine to cut strips of varying width.
In order to afford these rocking movements to the rock shaft 39, the shaft is extended, see .2, beyond the hand end frame andihas clamped thereon a bell crank lever 50, the upper rm of which affords a socket 51 which receives the rear end of an adjusting screw 52 which is entered through a lug 03 on the machine frame, and the screw carries a hand wheel 5% bearing against the lug :33, so that by screwing up the wheel. the screw stem 52 will lc drawn back against the tension of a spring 55 connect-ed with a short arm 56 of the bell crank lever. By unscrewing the hand wheel, the spring will rock the shaft in the opposite direction.
The clamping plate 20 is connected by strap links 57 to a cross rod 58 which is carried by slotted arms 59 mountec upon a rock shaft 60, which in turn carries an actuating arm 61 contacted by the bar 4-, so that an upward recession of the bar will cause the rocking of the rock shaft (30 against the tension of a spring 3 which enga the arm 64: on the end of the shz "1 The movable knife blade 2t is r' I y mounted upon the bar at), so tha the knife blade will partake of the entire line of movement of the bar, but the clamping plate 20, under the influence of the sprin 63, will have its movement arrested as soon as it engages the end of the metal blank, which it will do in advance of the arrival of the knife blade at the cutting point by reason of the amplification of movement occasioned by the greater length of the anus 59 as compared with the arm 61.
After the metal strips have been severed from the blank by the movable knife blade, they will fall down upon a sloping slotted runway 65 through which project a cries of fingers 66 carried upon a plurah endless chains (5? which are mounted upon upper and lower sprocket wheels (39 and 70 carried by upper and lower shafts ".7 and T2. respectivel The lower shaft constitutes the drivin shaft and in i: mounted thereon. at its left end a sprockc; wheel 73, best shown in l i which lliHs trates the trans -l inism from a point inside of the machine sprocket wheel 78 co-operates with sprocket wheel 74,- throurh the medium 0 a sprocket chain '75. The sprocket was 74 is mounted at the inner end of a hub which carries at its outer end an upper s gear IT meshing Vii ll a low-er spur gen,
y of
lit)
fit)
which is rigidly connected with a sprocket wheel 79 which derives power from a driving sprocket wheel 80 through the medium of a sprocket chain 81.
The hub 76 is mounted upon an upper counter shaft 82, and the lower spur gear 7 8 and sprocket wheel 7 9 are mounted upon a lower counter shaft 83, the two shafts being in parallel relation and ournaled with-in an adjustable bearing block 8% through which the shafts are extended. The inner ends of the shafts are passed through arcuate slots 85 and 86 in the adjacent wall of the frame 10, and each of the shafts threaded at its inner end to receive nut 87, the arrangement being such. that by loosenin-g one of the nuts, the associated shaft may be moved through its arcuate slot, so that the sprocket chain may be tightened or slackened to the desired degree, after which the nut can be tightened to maintain the adjustment. In this manner either or both of the chains and 81 may be tight-- ened or slackened to any do d degree. The driving sprocket is carried by the shaft 43 journaled within journal boxes 89 bolted to the rear portion of the end frames, and the drive shaft is driven by a pulley '90 or in any other suitable manner.
After the strips have been carried down along the runway 65, they are dropped into.
the space behind a clamping bar 91 and in front of the slot 92 through which the pro truding edge of the strip is folded by the advance of a crimpino' blade 93 drive by a cam 94-, but since these details are substantially the same as are defined in. the Yager' patent above referred to, and since they form no part of the present invention, further description is deemed unnecessary.
In operation a sheet of metal A is laid upon the platform 18 with its lower edge in contact with the protruding fingers 28 which are adjusted en banc to bring the required width of the sheet below the cutting line, the fingers being severally adjusted to present an aligned surface. Thereafter the machine is started and the reciprocating frame bar 40 will advance toward the sheet and as it advances the clamping plate 2 will forge ahead of the movable knife lilac c and contact the sheet in advance thereof.
The advance of the clamping bar and knife blade is accompanied by a recession of the fingers which are secured to the same reciprocating frame, the timing being such, lunvever, that the clamping plate will engage the sheet before the same has been released by the fingers. Thereafter a continued movement of the knife blade will sever the strip which will slide down sidewise until caught by a line of feeding fingers 66, which are continuously moving downwardly with the upper turns of the endless chains to which the fingers are attached.
The severed strips will be fed downwardly until they are released by the fingers and fall to the crimping point at which they are forced through. the slot by the crimping bladeand released from the machine.
The method of adjusting the fingers en oanc by means of the rock shaft 19 carrying the rollers i5 is one which not only affords a ready and easy adjustment, but also furnishes a roller bearing [for the finger frame in all positions of adjustment and involves a marked simplification and improvement over the mechanism set forth in the Yager patent. Furthermore, by mounting the finger frame directly upon the reciprocating frame, adequate means are provided for the coordination of the finger and knife movements, and a simplification of the c911- struction is effected as comparedwith that set forth in the prior patent above men,- tioned.
