In the practical embodiment of my invention, andfwithlparticular reference to Figs. 1 to 7,- I pro'videtwo frameworks, as at land 2, the said frameworks which differ in structure from each', other, being disposed, respectively, at the left hand side and at the right hand side of the; cutting device'or shears 123. The framework-1 which is situated in front of the shears 123, is-positioned at a distance of about 300 millimeters from the center'of said shears, thus leaving afspace for the attendant. On the said. framework 1, there are mounted tracks 3,,arid iconi'posedof U-shaped rails and upon which sausage-s mmer 5, serving for the forward transport of the material to be cut, is

adapted to "travel. As thewprofiled cutting blades of the. shears .123 are occupying different heights and positions, the said truck is provided with means .for,feeding the material 'to lowered by'means'of a worm-gear which com- .prises ,-the'worm'wheels 7, 'and,8 in connection with pressure spindles 9 and .10, respectively, and intermeshing .with the worm 11, which has Tattachedthertola crank-handle 12 for operation Thesaidtable has, pins secured to both ;its sides,.'fthes'e pins being designed for engageinent fwith slots provided ih laterally mounted plates ofsheet iron 13 and 14, respectively, and

serving asiaflg-uide for said table. Upon the latter is located a clamping device for firmly holding the'material to be cut, this device having 'jaws likethose of a vice, as at 15, and 16,

and each one of said jaws being adapted for movement in either direction by the operation oia'crank-handle 19. .The one of these jaws,

that is to say that one which islying opposite jaw has to exert the clamping-up action. Ow-

.ingstojthis arrangement, clamping of the material to be cut is rendered possible in accordv To this end, said truck carries a, table filada'pted to beraised and.

ance with the positions of the cutting blades of the shears, irrespectively of the positions occupied by said blades. In order to have accurate positioning of said stop-jaw and. of said table readily obtained, there are applied to said truck a number of marks which indicate the different positions occupied by said blades.

The framework which is situated' behind said device for cutting; comprises standards, the forwardly disposed ones of which are each com-- posed of four angularly shaped pieces 124 arranged in the form of a cross and between which are guided rack bars 20 adapted for up-and-down movement. Intermediate the members 20 and 21 are disposed flat iron pieces, which are made to penetrate at both sides between said angularly shaped pieces and guided therein. A U- shaped rail 22 which occupies a transverse position upon said rack bars 20, serves as adjustinggauge for the various lengths of the materialand is provided with an indicating scale 22', as clearly shown in Figures 1 and 2. The said scale is graduated in'millimeters from up to 12000 and more, as'the case may be, the said graduations being made so that the first three or five meters are divided into millimeters, whereas the remainder of the scale carries marks of division from to 5 millimeters. On the U-shaped rail 22 is'slidably mounted a stop 23 (see'Figure 2) fitted'with two screws 24 for clamping purposes. To prevent deflection of the profile rods during the cutting action, the said rack bar members 20 and the U-shaped members 21 are provided with angle tables having sliding rollers 25 upon which each rod is to be supported. Inthe case of rods of short length having to be cut, the said angle tables must be removed from the said members 20 and 21, respectively.

Raising and lowering of the said adjusting gauge together with said stop are obtained by meansof a shaft 26 and toothed'wheels 28, the said shaft being'journaled ingsingle bearings 27 and adapted for operation by a crank 29, as shown in Figure 3. In the body of the device for cutting, there has been provided'a passage, and through this passage, said shaft extends so that the attendant who is to occupy the space left between; framework and cutting device, is able to operate the shaft 26 by means of saidcrar k-handle 29 (see Figure 3). In order to havesaid arrangement secured against any displacement, the crank-handle 29 is provided with two flat iron pieces 30 disposed adjacent to and' connected with each other by means of intermediate members constituting a whole fof circular shape.

provided with holes having marks applied This ring shaped member is thereto and which are adapted for the selective reception of a split-pin 31, this split-pin having thus to serve as a'support for said crank-handle .29 in its locked position.

As clearly shown in Figure 7, there are provided strippers 32 which have for their oflice to throw down the material cut off the supporting rollers 25. The said strippers carry at top and base cranked flat iron pieces and are intended to be clamped to the upperand lower connecting piecesof angular shape at suitable places thereof, a set-screw 33 being provided for securing said strippers against displacement. If required, eachstripper maybe mounted so as to be .adaptedfor adjustment in height.

As ekemplified, the invention has for its object abutting device of the section iron and angle iron shears type, which'- may be "easily combined with a device for punching, as shown in'Figure 5. As soon as one rod hasbeen cut off and is' insupporting position upon the said sliding rollers, the latter'a'r'e lowered until said rod is in supportingposition on the respective which the rod is then gliding off,

stripper, from whereupon the rollers are returned.

The device for punching is mounted upona framework composed of 'angula'rlyf shaped iron pieces and having preferably an extent of 15 meters in working length, and a suitable height measuring about 1050 millimeters from top to lower center of punch. "Upon said framework, there are disposedtracks in the nature of U-shaped rails 36, on which a carriage 37 carrying the materi'alto be punched, is adapted to travel at the left hand side of the punching device, and a carriage 38'having to transport the material punched, is adapted to travel at the right hand side of the said punching device. A rope drive 39 disposed on pulleys 40,"is provided for imparting movement to said carriage in either directionjoperation of said pulleys being effected eitherbya motor of 1 HP or by a motor with gearing of any kind. Forward feeding of said-carriagewhich feeding may have an extent of about 250- millimeters, maybe either obtained by said motor drive or by hand operated means. 'To this end, a toothed wheel 42 is keyed to the driving shaft," said wheel being operated by the driving chain 42 .and the toothed wheel 43 to which is attacheda crankhandle 44; The steelwire'drive is at'the free extremity ofthe framework fitted with an au'tomatic tensioning device 45 with weight 46 to pre'vent'slacking of rope.

Rollers 4'7, i=8 are se'curedto the tracks constituted by the u-shapedrails 36, the said rollers being adapted for guiding and supportingi a steel tape-measure 49 having preferably 40 millimeters in breadth andcarrying indicating graduations'in millimeters. over -15 meters of its length. The said tape-measure is of the :endless type and provided with perforations-with which the twoend-rollers 50 having tooth-like projections 50 for that purpose, are made .to

engage to prevent saidztape-measurefrom sliding. At the extremity of said framework, there is located an element 51 of suitable type, this element serving as a tensionin'gmeans for said tape-measure which is protected :by abox 52. Suitable devices T are accommodated: at the left hand side and at the right hand side of the matrice support 70, these devices-.zhaving: for their oflice to operatively adjust the marking gauges for the material to, be punched. ,The said devices comprise, onthe one hand, indicating scales 127, and on the other hand, laws 53 which are guided positively, a rack-bar positioned below said jaws, being in engagement with toothed wheels 55 suitably mounted between said jaws. 'The operation of. said wheels by means of the crank-handle 56'att'ached thereto, causes said jaws to be-broughtin proper relation with respect tothe work to be done.

Sliding rollers 57 are suitably accommodated and adapted'to convey the material to be t'reated with great facilityso as to avoid undue friction. In order to secure most exact'measuringat the punch place, there is mounted intermediate the said'jaw members 53by'a bridge piece 128 which is also supported insliding rollers 129. a 1

The carriages ortrucks 37 and 38 each are equipped with a table adapted to be raised-and by meansof'a spindle 63 and a crank-handle 64 attached thereto. indicating scale is provided to permit of an' accurate adjustment of the piece oi work so as to position it in the center line of the punch.- =A flat-irori'hinge 65 carrying a bolt 66is provided,'said bolt havin to serve as a catch for the piece of work to be punched; A sduare iron member 67 is fixedly secured upon the carriage 38, thesaid square iron being-designed toiac't as a stop for the first perforation tobeipunched. The operation is as followsf. T "1.

After adjusting the tables .1 ofboth :carriages in'accordance'with thevrequired profile height, at which punching is to he: proceeded with, the piece 0f work inthe present instance an angle iron69, is placedsothat its ends are supported, on the one-hand,:by.'the'matrice standard 70, and on theother hand,byrthe feed "carriage 37, to which latter the angle iron is clamped in such a positionas to correspond exactlyto the axis of themarking gaugea After'.adjustment of the saidmarking gauge, the piece of 'work'is, for the purpose of punching the first-perforation, caused to move toward thestop member 67-, '68 until contacting with same, andi'after having said carriage adjustedaccordingly, the device is ready for operation. As .soon as-tthe first perforation has been punched, the catch-bolt 66 is being inserted into saidperforation, and. punching of the following perforations may be immediately proceeded with aowing to the carriage 38 being in connectiomwithithe piece of workby means of the catch-bolt. The steel tape-measure .49

zdrilling device, and this carriageis. provided with an interchangeable sub-table 131, adapte'd for the reception and for clamping thereto of the'mate .rial' to be drilled,- the said clamping zoperation being obtained by means. of;-:four.;-member.s in

the shape of jaws 8.7, asshownin Figure 14, the

.said jaw members being intended for operation ,by' the spindle 89 .and its crank-handle 90 :in either direction at pleasure. vThearrangement is made so that with the aid-of an indicating scale provided, all. of :the saidrjaws whichhave. to serve as stops-for the backs .of the angle .iron pieces tov be drilled, are capable of simultaneous placing each one :of the'said angle ironpieces in suitable position between the stopejaws, the

four jawsz88 which are provided for.:that purpose,.are by the operation ofsa -spindle9l and crank-handle 92, simultaneouslyi moved so as to cause clamping of the said angleironpieces. In close proximity-"to thedrill: place, there is accommodated a sub -table.1-32 like that carried by the truck-83,. as clearly'shown in Fig. 15.. A

plurality of..jaws'- 93 are provided, and all of these jawsare connected ,with. one .another. by

:means'r'of a spindle :94 havingrattached; to sit: a

crank-handle. 95 for simultaneous operation of .said jaws in either direction. Said jaws: 93; are

spaced from'one another in accordance withthe spacings existing betweenthe said jawsu.87; fand they are likewise adjustable with-respect 170113116 axis of the drill-spindle, an indicating scale .5133 being provided for. that. purpose... r,-It-; Ifollows therefrom that, owing to the intermediate spacings between the .j3.WS:'87 being identicalfwith those between'thejaws 93, the marking gauges of the pieces of work..@(angle-iron, channel and T-iron) to be drilled will at the drill place'be' also identical. The .material. to be .drilled, in the present instance angle-iron pieces, is guided .in a positive manner-in proximity. to thedrill place, andits. feed is assisted bythefollowing arrangement. Rollers 96 having an obliquer position are. provided and adaptedto travel-at top and bottom in .a pin, the said rollers being designed to take up the angle, side pressure during the drilling action. The saidrollers are--of:;coni- .cal shape,v andowingtto this construction; con-.

tact is forcibly maintained with the inner round corners of the angle-:iron pieces sqas; to'avoid a-rou h drill. Between thejaw members above referred to,--there. are accommodated supporting rollersfor the-said angle-iron pieces to be drilled. By means of'the arrangement described, there-.may be drilled fourangle-iron pieces-of from 25 to 200 ;m/m onv the said sub-table s1.- multaneously,.irrespectively; of the shape of these pieces which-may haveequal or unequal sides. The said rollers 96. are mounted on a common fiat ironbar 135 :in such a; manner as to allow oftheir tipping from oneside to theother for the purpose'of reversing'the position; of the pieces. of work; and .of having the other angular sideethereof drilled. Each one ofthe pieces of (work is .at the drill place guided so :as to avoid rough drilling thereof. 1 y r 'I'he carriageas at, 84 'hassto serve as a stop fori the first hole-to be drilled and is adapted foradjustment inview of thegfollowing perforations tobe drilled. Upon the said carriage, there is .mounted a secondone, 8.51313 97, ,this second carriage being provided with a support 98 in which are 'accommodatedmovably disposed jaw members 99. inconnectionwith a common spindle.100 and intended for simultaneous operation by acrank-handle ,101'in the same manner as the jaw members 87 and 93, respectively. The saidjaws 99 .have. each' a1 square-iron member 102;:which-serve1as a-stop and arefastened to the support '98. .Owing'to .a. shifting movement beingimparted to saidjaws ,togetherjwith their square-iron members the latter will become p0- sitioned so as to. contact withthe material to be drilled... The carriage 97-is, at thewstart of the drilling action, so lockedtojthe carriage 84 as to render, displacement .Of'. the same impossible, even if? heavy shocks should occur. The support or.. tabl,e 103,provided isidentical with that belonging to the carriage '83. To said support are atmthe propervmomentqc'lamped the pieces of workato be drilled, therebyv realizing a connection with the feed carriage84. vIn order to avoid dis- .placementy-of even most *minimal extent, the

.As exemplified in Figure 17, there'is provided a device, as at 104, adapted to be raised and lowered by means'of a rack-bar 136 in-view of having the perforations drilled in accordance with the 'linear and root-scales, respectively. Intermediate the: said device which is movable within guides 137, made in the structure of 'fiat iron,

provided are assisted'by a catchthere are accommodatedtwo jaw members 105 also-adapted tobe raised and lowered, and intended for-operation by a spindle 106 having a crank-handle 107. Both laws are connected with each other by means 10f a bracket. forming a bridge or yoke 108. over'the objectto 'be drilled, the saidbridgebeing adapted for horizontal movement in either direction and for raising and lowering, and having attached .to, it laterally a. die-rod. 109,,"thesaid attachment being obtained by inserting said rodinto the body --of said bridge and securing itagainst displacement. There is butone die-rod required for drilling perforations of any diameter in angle -iron, channel, and .T-iron. To this end, drill; bushes corresponding in cross-.sectionto theyarious diametersof the perforations, are employed, the arrangement being made sothata number of holes, in the present instance four, are provided in said die-rod, and these holes which have ,a. ,diameter of .36 millimeters,- are adapted. for

A to the extent of the framework. To prevent: sliding of the tape-measure, the same is pro machine, then brought in close proximity to said. It'is to be noticed in this respectthat all of'jtheipiecesfofwork to be drilled'are posi tionedf so asto be uniformly spaced frornfonef another, and's'o are the root-scales, too. There'-' the reception of the respective bushes. Owing to the fastening of said bushes being made removable, an easy mounting and dismounting of said bush members will result therefrom A steel tape-measure 112 supported on rollers and 1l1,respectively, and adapted to travel laterally of the framework, allows of thejadlustment of the spacings The said steel tapemeasurewhichis of 'theendless type like that employed with the device for punching, is pre vided with graduations in millimeters and protected by a sheet iron ,cover 113; it has lO milli-V meters in breadth, and its length corresponds vided with perforations13 9 with which-twoendrollers 114 are made to engage, the said rollers being for that purpose fittedwith proiections or teeth. The device 115 serves as tensiom'ng element for said tape measure, close pro imity to the'reading-ofi place, the tape-measure is caused to travelsupon-a plate. The readingofi place, in the present-instance center, pf drill spindle or graduation O isi-occupied-by-a hand 116 which isof the illuminated type and allows of a quick reading-oft. Feedof the carriage; work at the left hand,

allow of its right and left travel. v Torprevent' slacking .of ,rope, the same is connected to an automatic tensioning device 120 having a coun-:

ter-weight L21. With ,b,01'ifl devices for heaviest charges, there maybe provided ,achain drive in lieu, of the .said ropetackleblock. The operation ismas follows: 1

The material. towbe drilled, in the present: in-. stance angle-iron pieces, is after, completion of the cutting action by the cutting device, placed so that its ends are supported, respectively, on the carriageSB, and on the sub-table or support 103, and clamped. ,The steel tape-measure is in connection with the carriage 97 in such a manner that, the, said, carriage being in starting position, the; graduation 70 ofxthe tapemeasure corresponds to center of 'drill. spindle.

Both carriages may byhand operated means .be locked so as to prevent displacement thereof,

even if hardest shocks should occur. As hereinbefore described, stops 102 are carriedby' said carriage 9'7, the said stops being adapted for. movement toward one another and intendedfor;

adjustment of the first, second, andeventually. third perforations,v according to the spacings existing; Let it besupposed-that thefirst perforation should be drilled at a (1151731106'0140.

millimeters from the. extremity of the piece of work. Consequently, thetape-measure is to be adjusted so that the hand pointsto 40 millimeters. As the said tape-measure andlthe said.

wire rope drive are both connected to the carriage 97, forward feeding of the "tape-measure in with the 'wire rope results therefrom; When so adjusted, the pieces of. work to be. drilled are, by the useof the manually operated, mechanism at thelefthand side :of the boring machine. 7

fore, the holes provided foriin'thedrill dieior' die-rod 100 have also corresponding spacings;

Then, the bedis adjusted in accordance with the'inarking gauge and positioned uponj the; means of the raising anda s 1 W k by lowering device 104. The latter and the. bed

are'in an absolutemanner secured againStQviQ bration. 'The bed remains always the s ame v except 'howeverl for] drilling sheet-iron, and it is only necessary to adapt it to thedifierent marking gauges by means of a few rotations oi crank. I The pieces of work being brought in:

contact with said{stopi an the bed adjusted, drilling of the firstihole may be proceeded with. For the drilling of the following perforations,

it suificesfto adjust the required spacings. with I the aid. of the; tape-measuref The first perfoira tion being drilled, the carriage-9'7 together with the stop 102, is caused to move forward upon thecarriage 8; to a suiiicien t extent and to; occupy a new position in which it ,is locked by manually operated means. As soon as said carriage is occupying this new position, the

piece of work to be: drilled has reached the device 103 and is clamped therein. The electromotor is then started and causes forward feed-a ing of the carriage and the tape-measure. The motor is of the reversible rotary switc hutype and fitted with'a self-acting magnetic brake ior instantly stopping. A' ha nd operatedtoothed wheel drive 122 is provided and adaptedto-accomplish accurate adjustment. The guide membersfaccommodated at the drill place, as ex{ emplified in Figure 15, are not stationary, but

adapted for lateral ti ping by means of hinges provided, so that any piece of work may :be bored at either side and without causing disa placement of the support.

The drilling machine described may bejointly employed as punching machine. All of ,the, means provided remain unchanged, with the ex ception however of the bedwhich is made sink-n able and which is to besubstitutedby the de vice for adjusting the marking gauges. The whole arrangement, in lieu of being stationary, may be movably mounted, so .that the device for drilling may be shifted ,tothe device for punching, and vice versa, and inthis way used for punching or drilling purposes, asthe case may be. Besides, the punchingdevice inconnection with a cutting device for section iron, may be'combined with adevice for cutting profile rods of any kind,.without the employment of special marking elements (see Figure 5) 1 What I claim, is;
