y i f To all whom it may concern:

Bc it known that l, Enma MonMamc, a citizen of Norway, resxdlng 1n Ambrldge,

in the county of Beaver and State of Penn- 5 Sylvania, haie invented certain new and use ful lmprovements'in Spacing-Tables.

This invention relates to that class of spacing tables or parallel movers which are adapted to slipport aud move or permit and guide the movement of templcts and plates,

patterns and tools or other articles to be openated or operated upon in parallel relation to eachother.

The principal object of the invention is to provide. asimple, economical and eiiicient spacing table or machine for moving templets and plates or other articles in parallel relation to each other and adapted to be used in connection with or form a part of punching;` forming, cutting, stamping or similar machines.

A. further objectI is to provide suitable means for operating a spacing table or machine of the character indicated whereb)1 templets and plates or other articles may' be.antomaticalljr moved to a predetermined positionor positions while in parallel relation to each other, .by means of a suitable power. Other and further objects of the invention l will appear from an examination of the dra-wings and the following description andV claims, said drawings being made a partof this specification. The invention consists in the features, Y combinations, and details of construction herein described and claimed'.

In the accompanying .drawings Figure 1 -is a plan viewA of a machine constructed in 40 plied to or constituting an improved punc ing machine, the upper port-ion of the unch 'being omitted Fig. 2, a front elevation of' the same; lj'igl '3, an end elevation of the machine shown in Figs. lfand 2;l Fig. 4, an

In constructing a machine in accordance with my improvements I provide a plurality of elongated pinions or rollers a which are arranged in parallel relation to each other and all in the same plane, and journaled in suitable fixed supports or stationary bearings'b. These stationary journal bearings may be of any desired ordinary and livell known form and are mounted on suitable rigid or stationary supports such as I-beamsc which are adapted to form a strong supportin frame. Le s d may be es'ired, and tlie transverse frame members c may be connected by longit-udinal 4frame members of any desired form.

The rollers a are each provided with longitudinallj' extending gear teeth or ribs e, andin lar e machines where great strength is require supporting idler rollers f, journaled in suitable stationary journal bear-v ings g are mounted in su porti enga' ment with the central po ions o the ro ers a. The journal bearings for the rollers f are, preferabl nfpairs 'adapted to hold a 110 1ers f inftoothed engagement wlth catch of therollers a oir-opposite sides of the latter and in osition to form both a support and brace tierefor.

A, Inova le frame or table lar-formed lpreferably of metal side-frame members z' aving a space therebetween and rigidly connected by means of transverse frame members j, which are also preferably of brackets or'lournal bearings o whiehare infixed relation to the movable' frame, so that the rollers m are immovable longitudinally' with respect to eachother and`with respect to the movable frame. The teeth of the respective rollers or rotary raclcs'm eredirectly opposite each other or in, alinement and extend in parallel relation to the teeth or longitudinal ribs of the rollers a. The

brackets o are each provided with a lower rack portion yp each having one or more rack` teeth q in rigid relation to the movable frame and adapted to mesh with the toothed rollers a. side-frame members i is provided with an inwardly extending supporting flange r and the end-frame members arecacli provided with a similar in\vardly extending flange s for supportin in proper position in the spaces Il: and g, a templet t and a plate u lrrspectively, or adaptedto support a pattern and tool, or other article or articles to be operated or operated iipoi. Clamps u `which may be of any desiredordinary or well known form, are arranger] at suitable intervals along the edges of the movableframc or the spaces l: and l, respectively, in

position to engage and securely hold in place the templet and the plate to be punched,A

or other article or articles.

'Ihe supporting flanges, for supporting,

the edges of the templet and plate respec tively, are parallel, and the-inner edges of the rame members i and jrespcctivcly are provided with upwardly and downwardly extending inner surface portions adjacent to the flanges r and s respectively and form' ing shoulders o which extend above and parallel with said flanges. These shoulders .o on the transverse frame members j are paralleland should -be the saine distance apart as the finderand punch or other tool .when the finder is in normal position. The flanges 1- withtheir Vshoulders o adjacent to the spaces c and Z respectively, should he in alinement, so that the plate and tcmplet as foil as the supporting flanges and guiding ment, revolve.

The inner edge of Veach' of the shoulders of the respective spaces l.: and l of the movable frame will be at all times in correspondin positions witli'relation to the normal position of the nder and the punch templet and a plate respectively have a par-V allel movement, or are moved and guided iii` parallel paths.Y lfVhen the movable frame is moved longitudinally of the rollers a the rollers or revolving racks m on the movable frame revolve. lVhen the frame is moved transversely of the rollersl a the latter revolve, 'and when the movement is lohl ique in any direction both sets of rollers, in so far as 'the are in operative engageriction is thus reduced to a minimum and it is ossble to move the frame in any desired direction in a horizontal plane with great facility4 and in such a manner that the parallel movements and relation of corresponding parts of a tempiet4 and of a plate to be punched, or other articles to`be operated or operated upon,

`may bemaintuined with accuracy and with 9 a single movable table or fur'nig. The tahle may be operated manually when desired, but I haveV provided a simple -and efectivc 4-mechanisin whereby 4it may he operated hy the application of power such as hydraulic power, compressed air, or other [luid pressure,-or power. My improved device or mechanism for securing parallel motion of templet and plate, or thc like, including the power device for4 operating the inovahle fraaie, is particularly adapted for use Vin shifting, supporting and punching duplicates or metal parts for heavy work, and for punching 9imaking articles from or in accordance with a pattern or teinplet.

A plinchor other tool '2 is mounted in a suitable support such as the upper jaw 3 of a punch press having.'l alowcr jaw 4 and a punch plate 5 supported by thel latter hclow the movable frame above described and in a position which will permit thc frame und the plate or other article u which is to he opcratedupon t'o be moved in any desired direction in a horizontal plane to any posit tion which may-he necessary in ordcr to present any desired part ofthe plate or similar article in iosition to he operated upon by the punch vor tool. Mounted upon a. suitable stationary support 6--Whirh may be in the forni of a. rigid how formed of an I-bcam'and extending across and over the movable fralne-is a stop 7. rThis stop, in this instance, consists of the end of the pistbn cylinder 8 which is rotatably supported in a position which will permit the movable the stop.y 7A formed an outlet :opening 2O which A portion er the piston r shoulders,

' the va ve bv frame and thereby the templet or pattern or any desired part thereof to be moved .to a

Eositon directly beneath or to be determined the stop 7. The position of the stop 7 isconstant' with respect tothe position of the punch or tool 2, and the cylinder 84 is slip-V ported by and. in fixed relation to a rotary disk or turn-table t) which is rotatably supported bya ring 10 whichfis in tuin su J- p orted by the stationary bow 6 to which tie any desired ordinary manner.. The rotary diskthus forms a pivotal support for the piston cylinder 8 the pivotal center of which corresponds with or is directly over by the inner end of the piston ciylinder. An upright lflu'id'-su ply ipe 12 ocated at the nvotal center o the isk and piston cylin e'r extends upward throu htlie center of the disk and is connectet with a suitable source of fluid supply or source of power,A the l pipe communicating witlrt ie interior of the 'iston cylinder with which it is connected y means of the Jipe 13. The fluid supply passage formed y the pipes 12 and 13'is controlled by a three-way cock or valve 14 having converging passages 15, 16 .an d 17, 'as .shown in Fig. 7. The valve casing or elbow 18 is provided with a port. 19 leading into the pipe 113 and. thereby eoiiiiiiunicnting with` the interior of the piston cylinder, and has is adapted to cemmunnicate-ivithvthe passageV 1.7 when the inlet passage 15 is closed, thus forming an outlet from'the piston eflinder through the ipel, port 19, passages 16 and 17 and outet port 2O whic is adapted to permit the escape of pressure fluid 'sin'iultaneoi-isly with the closing'of the inlet passage but prevent the escape of fluid when the inlet passage is open. v

A lever 21 is operatively connected with l means of the valve stem 22, as shown in Fi ..4 and 6. A piston 23 is mounted in t piston cyliiideiand is provided with apiston rod 24 having a depending 'end portion 25 in which is mounted a vertical and" vertically movable finder or positioning bolt 26 having 'a handle 27. A'ca 28 in the' lower end of the piston is rovide with a central the finder exten' 4 and an inner collar 29; 0n olt," serves to limit the downward or outward movement ofthe latter and engi'tges a spiral springr 30 in'tln hollow "depending u. This springen'- circles the boltl or finder 'and serves to yieldgingly hold 'it in extended er-lowered 'position' and in engagement with or with the movable 'frame farms rod are adapted to engage the lever 21 as ,the piston approaches `the: end of its stroke, and thereby. t-urn the'valve 14 Transverse ring is secured by means of bolts 11, lor in the fluid inlet wer end of said `\vith the position of a lio by the finder perforation throng which' tli'ei'tinder to A. ranged that it is .in
