To all whomY t maj/concern: n

Be it lmownthat I, THOMAS E. GAHAN, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain, new and useful Pattern-,Performing Machine; and I do hereby declare the following to be a full, clear, and eXact description of theinvention, such as will enable others skilled in the art to which it appertains to make and useV the same, reference being had to the accompanying drawings, and `to the characters of reference marked thereon, which form a part of this specification. l Y

Thisinvention relates to` perforating machines, and particularly to those adaptedfor perforating master pattern sheets. The yobject of rmy invention is theprovision of an improved electrically operated machine of the .characterdescribed, which is simple and inexpensive in its construction and easily operated to perforate sheets of paper or the like in a rapid `and efficient manner. Further objects and advantages of the invent-ion will be apparent from the following detailed description thereof.

While the invention, in its broader aspect, is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a machine embodying the invention, with a part broken away and with a pattern .sheet in operative position therein. Figs. 2 and 3 are different enlarged views of the sheet operated electric circuit interrupting means, with portions of the latter in section. Fig. 4 isla top plan view of the machine. ig. 5 is an enlarged perspective fragmentary view of the sheet perforating means, andFig'. 6 is a sectional y fragmentaryelevation thereof.

, yReferring to the drawings, l designates a frame, in the present instance, of elongated triangular form, which is provided at its corners with ball casters 2 to permitv a free movement ofthey frame over a smooth surface, such as the top of a bench, table or the like. 'The forward or apex end of the frame 1 is provided on its topwith a platform 3.

`Arms 4, 4 projectforwardl in convergingl relation from the rear end of the frame l in substantially parallel superimposed .relation thereto, providing a narrow space 5 therebetween'to permita patterny sheetA tobe freely insertedtherein. The forward 'ends l of thearms l, .flare connected by block or bar (Shaving an aperture for a perforating pin or punch 7, which, when depressed, coacts with a die-block 8, carried by the frame 1, to perforate an interposed sheet A. The sheet is yieldingly held to the under side of the block 6 at the point of perforating by a spring finger 9 carried by the block 8. The yupper end of the pin 7 is headed and a coiled compression spring l() is disposed between it and the block 6 to retain the pin normally elevated. A lever l1 is pivoted at 12 kbetween the forward end p0rtions of the arms 4, .et above the block 6 and has its short arm Ycoacting with the top of the pin` 7 and its long arm extending rearward and connected by a link 13 to the lower end of the armature or pole piece 1i of an electrofmagnet 15 of the solenoid type. The electro-magnet coil is carried by a framel rising from the arms el, e. 1t is evident that an energizingof the electro-magnet will rock the lever 11 and effect a depression of the perforating pin 7..

A pair of arms 17, 17 are rigidly liXed at their rear ends, inthe present instance, to the rear ends of the respective arms fl, l and extend forward on Lan incline Vand in converging relation with their free ends secured together over the platform 3 in vertically spaced relation thereto. The arms 17 17 may be referred to as a forked' arm or superframe.

A disk 18 of insulating material is carried by the arms 17, 17 at their under sides over the platform 3 and has a mrrginal electrical Aconductive ring 19 Onits top surface, with a terminal post 2O 'rising therefrom.

A vertical spindle 2l is journaledin the arms 17, 17 axially of the disk 18 and car# ries a turn-table 22 of insulating material below saiddiskl kin spaced relation thereto. An electricalco'nductive ring 23 is mounted onV the top marginalledge portion of the table 22, andwith it an electric brush 24C has e yielding wiping contact. This brush is carriedl by a terminal post 25, which projects up through the Vdisk 18 free fromcontact with the ring 19 and is insulatingly fixed to a side of the arm 17.

A caster-wheel carrying vvfork 26'depends on an incline from the 22 centrally thereof and carries, what may be termed, a. commutator-wheel 27, which rests on the platform 3 or on a sheet A dis'- posed therebetween, and is intended tobe rotated by .the movement of a pattern bottom of thetable f n sheet over the platform 3. A coiled compression spring 2S encircles the spindle 21 between the arm 17 and table 22 and causes the wheel to have a yielding,downward pressure against a pattern sheet with which it coacts. rlfhe wheel 27 has a. plurality of equidistantlv spaced radial electrical conductor strips 2.9 having insulation therebetweenrand electrically connected at their inner ends in the manner of a commutator ring.V The strips 29 have their inner ends in electrical connection with the ring 19 through the wheel spindle, fork 2G and an electric brush 31, which projects from one side of said fork around the edges of the table and disk 18 with its free end in yielding wiping contact with the ring 19 (Fig. 3). f

A small wheel. 32' serving as an electric brush member is carried by a rocker arm 33 in yielding contact with a side of the wheel 27 so that upon a turning ofthe wheel` 27 on its axis the wheel will have alternate contact with the conductor strips 29 and insulation 30. The contact wheel 32 is in electrical connection with the ring 23 througlithe arm 33, sha-ft 3l carrying the same, shaft bearing 35 and bolts or rivets 36, which bolts or rivets secure the bearinO 35 to the D fet under side ofthe table. QQ and have contact at their upper ends with the ring *23. A coiled contractile springA 37 connects an arm 25S of the shaft 341- t-o the table 22 and serves to holdY the wheel in yielding contact with the commutator wheeh In theY wiring illustratech 89 designates one side ofthe line which is connectedl to the post 20, and Ll() the other side of the line which is connected to the post 25 and has a control switch 41, the coil of the electromagnet 15,r and a circuit breaking `means disposed therein The circuit breaking means is automaticalljvT operated`A to break the circuit at each upward movement of the rear end of the perforating lever 11 and is for the purpose of' causing `a more rapid making andi breaking of. the circuit than would be possible if the commutator wheel was alone depended on forv such purpose andV also for the purposeof preventing yan injurious arcing from occurring beti 'een the wheels 27j and 32 as the contact betweenthe latter and the strips i9 ofthe former is broken.

The circuit breaking'meanswhich have illustrated comprises 'a rocker arm ft2. which is pivoted for vertical rocking movements in a stud. el?) projecting from aninsulating bpard et@ whichfis carriedv by a standard tfrising from Vone end ofthe arms i. The armA l2 carries carbon1 46,' which coacts with a subjacent carbon.' 47 to limit the downward rockingmovementoff the arm, the carbon l? being adjustablv carriedbv a bracket 48. The circuit wire "-lO is splitA and nearest has one end connected to the rocker arm 4:2 b v a binding screw L19 and has an end connected to the bracket d8 by a binding screw 50.- lt. is thus evident that when the carbons sto and 47 are in contact the current is permitted to flow through the line, and the circuit is broken byr a separating of the carbons; A spring finger 5l is fixed at one end to the board de and acts at its other end against the rockerarm 4t2 to resist an upward or circuit breaking-movement thereof. Ak linger 52 is adjustably carried by the long arm of the lever 11 and projects upward therefrom in position to adapt it,;

when raised a predetermined extent by a rocking of the lever, to engage an insulating block 53, adjustably carriedY by the roc te* arm i2, and effectv a rai-sing vof therocker arm to separate the carbons and #f7 and break the circuit. ltI is evident that during the period of contactof the contact wheel 32 with a Contact strip 2 9; ofthe coinmuta tor wheel the lever'll is caused to have a rapid vibrator;v movement due to the breaking of the circuitr at each upward movement of the rear endV of' the lever andthe closing of such circuit at each domiward movement of such end'of the lever. Y

ln the use ofv my machine they sheet: A to be perforated is anchored at its ends or in some other suitable manner against movement and the machine is moved over the sheet as the perforating of the same may require. To facilitate suchy movement the machine is mounted on the casters Q topermit a free movement of the same over the bench, table or other support, and the rear end' of the machine is provided with a handle 5l to be graspedY by one hand ofthe operator7 said handle, in the present in stance, comprising a boltr which connects the sides of the frame 1 at their rear ends, while the other hand' ofl the' operator is intended to grasp a handle 55, which extends transversely from the forward end of the superframe or forkl'r'. a

ln the operation of my machine, an 'operator places a sheet A in the space 5 between the frame 1 andA arms d' andb'etween the platform 3 and commutator wheel 27, with the perforating pin 7 disposed at the point where it is desired tol commence the perforating ofthe sheet. `The operator then closes the switch y171 and moves themachine with respect to the sheet A so that! theperforating'l pin 7 is caused to follow lthe line to be perforated. The movement, ofthe machine in whatever direction with, respect to the sheetwill cause the cominutator wheel 23 to rotate so as to successively make and s break the electric circuitbyreason ofthe conductor strips 29 of the wheelfsuccessivelv moving intov contact Vwith the contact wheel The closing ,of the circuit intliisman-l ner causes an energizing of the electro-niagnet and a consequent movementfof the lever ll toimpart a perforating-movement 'to the pin 7. Upon a'raising 4of the rear again impart a perforating movement to the lever l1 and a consequent separating of the carbons to again break the circuit, this beying repeated as long asthewheel 32 and a contact.

strip 29 ofthe commutator'ivheel remain in It is evidentvthat theavheel 27 always has a trailing action with respect `to the direction ofmovement ,of the machine,

the table 22 turning With the orbital move ments of the Wheel. The brushes 24 and 3l remain in ypermanent rContact With therespective rings 23 and 19 during avturningy of the table so that the circuit is not broken by reason of such turning.

It is evident that I have provided a simple and efficient perforating machine, vvhich is capable of being easily operated to effect a rapid perforating vof a master pattern sheet and that the rapidity of movement of the perforating pin does-not dependentirely on the speed of turning of the commutator Wheel 27. f v i,

f I Wish it understood that my invention is notr limited to any specific construction, arrangement or form of the parts, eXcept'in yso far as such limitations are specified in the claims. n f
