15 Claims. (01. 144-251 This invention relates to a combination guard and support for a jointer fence; Morespecifically it relatesto a device for guarding that portion of the jointer cutter which -45 is not being used for a given settingof thejointer of'thefence. v

n Another object'is to provide means to support the jointer fence-at a point remote from the front end thereof, wherebythe yielding or'play of the I jointer fence may be minimized, said support, nevertheless,permitting the fence to'be tilted fence, namely, ordinarily the portion to the right freely to any desired angle with the'jointer tables.

A. further object is to provide such combined I guard and fence-support, which need not'beremoved from the machine regardless of the position of 'adjustmentpf the fence, sothat no porktion. of the cutterknives will ordinarily be exall .parts of the cutters.

I

The fence 35 is secured tothe-rotatable head 25, by screws or'similar means 35, said fence having a work-guiding surface ,31. -The head 25 is supported upon an arcuate annular rib .24 formed on the bracket [9, said rib'fitting slidably within a corresponding groove 26 in said head, whereby thehead 25 may be rotated about the center of the said finer rib 24' to thereby carry the fence 35 to any desired angular inclination with respect to the top surface of the work tables l2 and l3,:said head being securable to the bracket 19 in the desired angular position by means of the screwlZlhaving the operating handle 28, and by the sca1e8l.

The bracket, as a whole, is also slidable transversely of the table'l2 by means of slots 1 1 formed in the lower surface of thefront portion of said table I2, the bracket having projections I8 fitting into the said slots and a screw20 cooperating with the bracket l9 andtable l2'to secure the bracketin its position of transverse adjustment, said screw being conveniently provided with an operating handle 2 1 The fence may be -provided with a supporting lug 39 serving as an intermediate bearing for the same, in order to'prevent said fence from sagging downwardly with respect to the tables [2 and l3. The fence '35 is preferably provided with a hollow, as shown at 38, in order to decrease the" weight thereof, while still affording adequatestrength and stiffness. The fence also has a portion cut away as shown at 40 to accommodate the cutter II and prevent: contact of'the'outter blades with the fence, regardless of any position of adjustment'of said'fence .and tables.

, Theabove. details of the-construction of the jointer form no essential part of the present invention, are disclosed in the prior patent of Herbert E. Tautz No. 1,790,288, dated January 27, 1931, and are included here merely to complete the disclosure and assist in showing how the present invention cooperates with a jointer, particularly one of the type disclosed in said prior patent. V p

A guard I having a'pivot shaft 2 therein, coacting with a lug 3 on the table I2, may be provided to guard the left hand portion of the cutter blades, that is, theport-ion shown atthe' left hand side in Fig. 3 and shown at the bottom in Fig. 1. This guard may be of the now customary type, having a'lug 4 thereon with an aperture 5 therein to receive a spring '6, the other end of which may be engaged in a suitable aperture 1 in the table :12, ,thezeffectmfssuehg spring being to urge the guard l upwardlyin Fig. 1 or to the right in Fig. 3, so that this guard will always beheld against the work-guiding surface .31- of the fencexifi and will effectively :cover that portion of the cutter extending to the le'ft of the fence inFig. 3, the ,guard being so. shaped tha t.it=will be automatically pushedaway when aboard is being machined by the jointer,-'but will again resume its initial position as soon as the board has .passed beyond the cutter head, thus protecting the hand of 'theroperator from accidental contact withthe left-hand end of the cutter headl'l when-using the machine.

In -jointers of :the type :disclosed in ,the prior patent, even when'providedwith aguard such as shown at l,..in the present case, there is no protection :whatever against accidental contact :of .the .hand or clothing of the :operator with thec'unused or. right hand end of the cutter, namely, the-portion extending to therightof .the fence in .i-Fig. :3 of-the present case. It:is obviousthat inasmuch as, ordinarily, relatively thin boards arebeing-planed'inv an endwise position upon the jointer,- the fence-would often be fairly close to the:leftzh'and edge of the table, thus leaving a considerable portion of thecutterto'the right of :the'saicl fence absolutely unprotected in any way. This isparticularly :the case when the jointer is being used for cutting rabbets, because-in such 'rabbetting operations the jointer fence must necessarily be near the left hand edge of the'table, inasmuch as the width of the 'ra'bbet is determined by the .distance of such fenceifrom' such-left'hand edge andmost'rabbets are relatively. narrow.i

dn'orde'r to protectthis unused right hand portiono'f 'the cutter II, there is provided, in one form of :the .present invention, a guard, .indicated generally'by thereference character :8, mounted o'n'atsupport9,.secured preferably to an extension-or 'lug 22..formed on or attached to thefront table I2. This support or post Brnay, for example, be securedto-said lug '22 by means of a screw-threaded portion 23 threaded into the lug 22,.as best shown in Figs. 4 and '5. The top of the support .preferablyisflat, as indicated at"80, and said post 9 has a screw-'threaded boren therein to receive a screw 38 having a'conven- .ient ssta'rzshaped head32 for operating the same. "The guard 'is provided with a slot running substantially its entire lengthand displaced considerably 'from'the center line of the. guard. The guard-may .be provided with-a seriesof ribs "42, 'm'ore=or iless arbitrary in'number, said ribs-thus ,producinga skeleton orbasket type of structure which makes the guardlight in wei'ght and yet sufiiciently strong, vwhile affording a view of'sthe :need .'not include any further features.

cutter beneath the same so that the presence of any foreign matter, such as fragments of wood,

-may be readily seen. The slot 4| is of sufficient width to allow the screw 30 to pass easily therethrough, thus permitting the guard} to beshifted freely to the right or left throughout the extent of said slot and then permittingthe guard to be clamped by- -merelytightening the 30 by means of the"star-'wheel*32;'*

It is obvious that the structure thus far described will constitute an efficient guard for the right :hamlportionofthe cutter head H, and

However, a furtherpurposemay also be served by this guard, namely, itfmfay be made to serve as an additionarsupport :orbrace for the fence 35.

In order to accomplish this purpose, means, suzhras the:lugs"43 5nd 44, may be provided, preferablyintegral with the fence 35, said lugs having preferably parallel grooves 45 and 46 provided therein, the. guard :8 :having an: extension 41 with lugs or pins Aland!Q-pr vided-themcm and slidablyeengaged in the respective-grooves and.

Fig.6 the fence 35 is shownq-as'provided with. a curved lower end- 3l sai d curved portionbeing either cylindricalor spherical in nature, and cor.- respondingin its location .to the supportin lug 39. of ;Fig.2.'. The cross. section of said portion 3| is, of course, bounded by a circular arc, regard,- essof-whether the actual element. is spherical or cylindrical, so that the-same illustrationserves. forboth. t This circular portion is so: located that the circle of which itais a part is tangential to the work-guiding surface 31 of the fence 35. "A slotted bar 33, having. a longitudinal slot..34 therein, cooperates withthis curved supporting-end 3|,

' that is, the. left hand end 50 of saidbar bears against the right hand extremity 0fportion 3l. The bar 33 i s- .l 1eld -tov the front table I2;;in1,anydesiredg'way, torexample, by'means of a screw 5| having :a, wing nut 52 and lock washer 53 cooperating therewith, the Washer .53 bearing. against. the upper surface ofthebar 33, on opposite sides of the slot' thereof, and wing nut-52. serving to secure the bar 33 adjustably to the table l2.

' guide pi-n54 is also preferably providedand maybethreaded into-the table l2, as shown, at 55 whereby the free end of the pin projects intothe slot'34. 'ThlS pin 5.4 ispreferably spaced from the bolt 5| and both-the shankof the boltfland thepin, 54are preferably of the same diameter and; fit fairly snugly into-the slot 34 so that the pin'54, together withthebolt 5| will prevent the bar '33 fromassuming any other than. a desired direction which is substantially at rightangles. to

; eyelet or? other securing means 56 isprefer-l ably provided on the bar 33 and another eyelet or the like) 5' isv arranged on the .fence 35 as illustrated. "-A..tension spring. 58' is-arrangedto be held bythese two eyelets 56 and51 and isofsuch len th and construction that it will always be under tension regardless of the tilting of the fence-35. andyet willnotbe strained beyond its proper limits in the course of any such .tiltingof thefence in eitherdirection. Preferably also the eyelet or the like 51 onthefence 35 .will be located at {a point not. too high above the plane of the top. of the table 12, so that the pull of thesp-ring 58 will always be exerted in adirection not exceedinga relativelysmall angleto the general direction of the bar-. 33. I 1 fIfhe structure just described vmay-be.supple mented 'by' a guard for, the right handportion of thejointer linivesby combiningit with suitable means which will cover said jointer knives and willj follow the said,bar inits movements. This may be accomplishe d, for example, as shown in Figs. 7,8 and 9, wherein the bar 33 is supplemerited by a guard for the jointer knives, this guardlbeinga lazy tongs'gdesignated. generally by the reference character 59 and pivotally supported at one end 60 on the front table I 2, whereas its other end 6 l is pivotally supportedona lug or the like 62 formed on the bar 3 3, as best shown inFigJT, The lazy tongsconsists, of course, in the customary way, of a series of bars. secured to one another. by pivots and extensibleand contractible ajdirection parallel to the length of the bar 33. It isidesirable, of course, to support the lazy tongs a slight distance above the tops of the jointer tables in order to avoid .-interference with the jointer knives and also to provide amore'eifec; tive guard. S;may be accomplished by arranging the pivot 60. .upon' a raised lug ,or. extension 63, best shown irrFigt8, and by providing spacing members 64 and.65 below the outer pivots of,

the lazy tongs 5 9, as shown best in Fig. 9. These spacing members orfeet will, of course, prevent the lazy tongs from sagg ng and coming into accidental-contact with .the jointer knives, while permitting the lazy tongs to slide freely backand forth to-correspond to the'adjustment of the bar 33.- The spring 58 supported by the eyelets 56 and 51 is arranged in. the same way as in Fig. 6, in fact-the form shown in Figs. 7., 8 and 9 contains all the structure of Fig. 6 with the addition of the lazy-tongs guard. v e

A further development of this general idea is illustrated in Figs. 10, 1 1 and 12. It will be noted that. the form illustrated in these three figures combines certain features illustrated in Figs. 1 to 5 with certain other features illustrated in Figs.

'6 to 9. This form of device comprises a support,

Referring first to Fig-10, it will be se n that Y thefront table I 2 carries a telescoping guard comprising a flattened or basket-shaped member 66 secured to a slotted bar 61. The said bar 61, however, differs in its details from the bar 33 in that it is formed as a channel bar having slots in two different webs thereof, as best shown in the cross section illustrated in Fig. 12. I

The lower slotted web 10, of this bar 61, provides a guideway which permits the bar 51 to slide along over the shank of the bolt 68, which has a wing .nut 69 cooperating therewith, the head 'H 'of said bolt gripping over said portion so that by loosening the wing nut 69 the bar 61 may be slid along to a desired position of adjustment, whereupon tightening the wing nut 69 willserve to secure the member 61 in its adjusted position. The guard 66, which may consist of a series of rods or anyother suitable protective structure, may be formed integral with, or secured in any other desired way to, the bar 61 whereby said guard portion will cover the space between. the front table l2 and the rear. table [3 and prevent,accidental contact with the jointer clear that the structure thus far described and comprising the guard 66 carried by the bar 61 is substantially the equivalent of the structures shown in Fig. 3 and in Fig. 6,.that is, it provides a rigid non-extensible guard combined with a supporting bar. 1 p

However, in certain cases, it is impossible, to make theguard .66 of sufficient transverse dimensions to cover the entire unused or free portion of the jointerknives, for if this were done then the guard would project too far to the right when the fence 35 is also moved to its extreme right handpositiomso. that the guard would then interferewith parts of other or cooperating machinesmounted adjacent to the jointer, thus precludingthe use of a guard of the type shown in Fig. 1-2, from which figures it is evident that -'upon loosening the wing nut 52 which isthreaded upon *the ;bolt 5| the bar 13 'a-n slide alo'hgt he 1owerbar'6'l. The upper bar 13 maybe'provide'd with a depending portion I4 fitting in the upper channel 15 of thelo'wer bar 61 and the bolt'fil passes through 2. Suitable aperture 16 in the web 82 of said bar, thus permitting the bar 13 tobe adjusted with respect tosaid bolt -5l, due to the slot 17 therein. A spring 58, together eyelets 5fi and5 'l, arranged on the bar 13 and on the 'fehce'35 respectively, may be "provided, said parts having the samestructures' and functions as in Fig. 6. t t 7 It will be obvious that while in Fig. '7 the extehsible guard 59 has alarge number of separate parts or sections; namely, the pivote'dbars, while the extensible guard shown in Fig. 10' has only two'p'aif'ts' or sections, narri'ely, 6 6 and 12, yet the number-of such seetions or'part's 'is,'of coiirse, arbitrary and the 'terin niiinber is, therefore, used in the present specification and the claims in its -mathematical sense to designate any integr-al positive numben inclusive, of course, of

unity, that is, the expression number is equiValent to the expression one or more and does not necessarily mean a plurality.

fThe operation of the various devices is asfol- I'O'W'SE l t'eierring' first 'to the form illustrated in Figs. 1 to 5 inclusive, the cutter head 'II will be driven in any suitable way, for example, by a belt engagee on the puley l8. The knives 'or blade of this cutter'head are protected from accidental contact with the hands or clothing of thepe'rson (i-berating 'the iriachine by the two respective guards, i on the left and 8 on the right, these guards being shown respectively at the bottom and top in the position in which the parts are illustrated in Fig.1.

' When' it is necessary to adjust the fence to expose any desired portion of the cutter head blades to the'left of the work-guiding surface '31 of the fence-35; it is requisite -r'n'e'rely to loosen the star wheel or nut and then to loosen the screw 20 by means of its handle 2|, said parts being best shown in Fig. 2. This permits moving the fence 35 manally to the left or right-as desired'ahd upon completion of such adjustment into the desired position, suitable for the work to bedone on the machine, saidsci'ew lil is again tig'htenedtb'clamp the front'erid of the fence 35 securelyto the front table i2. I

Meanwhile, the righthand guard 8 will have slid to the right orleft, following thefe'n'ce -35, diie t0 the pins 48 and "49 slidably engaging in the grooves and 46. When the forward end of the fence is'thu's secured by means of the screw 20 and the guard 8 has assumed a. correspending position of adjustment, the" star wheel 32 may be e'iiiployed to tighten the screw 3b in the bore 29, thereby clamping the guard BS'ciii' ly' 'to the post 9 and'thus providing a rigid non yielding support for the fenceJS-at-a' pom't'spacea Contact or the clothing or body 6: the opeffitoi tame 1'2 Without causing the gu'ard' '8 to be are engaged-1mm said whee, this adjustment being made, of coii'rse, before the --sta'r Wheel 1238 tightened, whereupon tightening of the stat wheel will to "clamp the fence 35 in whatever adjustment it may happen to be, both transversely of the table i2 and at an angle to said table. It is 'alsoclar that by rea'sdn 'of slot and pin connection between the guard Bind the fence 35 nt additional means are hece'ssary to cause "said gum-a to renew the'ihce "is in it'svar'ious movement's. y 7

Referring now tothe fence support illustrated in Fig. '6, the operation thereof will "be yery' fead- 11y understood from theurawmg's. "By loosening the wing nut 52, the bar 53 may move "freely in a 'dirctl'onftransverse to the general direct on of the leh'gtihhf the "fence -35, and censequ'ehtiy spring 58, which engages the said ienc Well as the bar, will always cause the-end '5! at said bai- 38 to engage against the arcualte surface "at 3| oh saidien'ce a5.

Furthermore, even if 'thefencef85 is adjusted a guiariy, that is, inclined, with respect to 'the table =1 2, this will not jiriteftere' with the engageineii't'o'f said'en'd against the portion 3|. The only o eration necessar in adjusting this "device, therefore, "is ffirst to loosen the wing nut 52, "thereupon "adjusting the fence"trarisve'rsel'y or angular-1y, or both, as permitted by the screws 20 and 21, then again clamping said i'en'e'e in its adjusted position by 'meahs'o: said screws a'ind finallyti'ghtenihgthewing nut 52, 'whei-eupon'the bar 33 will be held securely against "the "table I:

The Supports or buttons 64 and 65 will prevent the lazy tongs 59 from assuming too low a position, where the bars thereof might come into contact with the cutter head or might permit accidental access of the fingers or clothing of the operator to said cutter head. It will be understood, of course, that the number of bars in said lazy tongs may be chosen suificient to make the intervening unguarded spaces as small as may be believed desirable in any particular case. The bar 33 in this form of the device'will operate as a support forthe-fence 35'precisely as does the identically constructed bar 33 of Fig. 6 sothat it is' believed to be unnecessary to again describe such operation.

' Referring now to Figs. 10, 11 and 12, it will be noted that both the bar and theguard have therein been made in two sections instead of in a single rnemberas inthe Figs. 1-6 forms. This has an advantage, in certain cases, in that the said guards, as. well as. the bars supporting them, will not'extend too far to the right when the fence 35 is in its extreme right hand position, this advantage being gained due to the telescoping or slidingaction of thetwo sections of the guard. The spring 58 is preferably secured to the upper bar 13 so as to hold the left hand end thereof against the arcuate portion 3| of the fence 35, as in the preceding forms, and it will, of course, be obvious that such connection will avoidundue variations in the length of the springwhen the fence 35 is moved to the left or to the right, as would be the case if the spring were secured to any other portion of the other bar 61 of the mechanism.

By loosening-the wing nut '52 it is possible to move-'the fence 35 to the left or the right when thescrew 20 is loosened, to an extent corresponding to the'motion permitted by the bar 13. In such adjustment thesection 12 of the guard will move back and forth across the top ofthe section 66; w

For a greater, motion of the fence '35 to the right, the wing nut 69 may also be loosened, thus permitting both bars, namely, 61 and i3, jointly to nave-"to the right, and thus also permitting the full rightward motion of the said fence.

The fence 35 can, of course, be tilted just as in the other forms of the device and the spring 58 will provide continuous abutment of the end 19 of said bar 13 against the arcuate portion 3| of the fence, as in the preceding forms. When the fence 35 has been adjusted into its desired position and clamped there by the screws 2!! and 21, the additional supporting feature of the bars 13 and 61 may be secured by tightening the wing nuts 52 and 69.

It is obvious, furthermore, that when additional support of the jointer fence is not particularly necessary, as when the jointer is being used for relatively light cuts, or light workpieces, it will not be necessary to take the trouble to tighten the clamping means which hold the various supports in the different forms of the device.

Thus, the device shown in Figs. 1 to 5 may often be used with perfect satisfaction by leaving the star wheel 32 slightly loosened, whereupon the guard 8 will still perform its function of guarding the unused portion of the cutter head but will not perform the stiffening or supporting function, and similarly in the forms shown in Figs. 7 to 12,

of the machine for light work and eliminates unnecessary manipulations, while it does" not in any Way interfere with again quickly obtaining the supporting function by 'merely tightening the various nuts or screws when such feature is desired,

The Fig. 6 form, of course, is of no utility unless the clamping feature provided by the bolt-5| and wing nut 52 is used, because this form does not embody the guarding structure.

It will be obvious that the present invention provides two separate and distinct functions which are, however, produced by unitary or close ly combined structures, namely, the guarding function and the supporting function, but, nevertheless, these functions may be used either jointly or independently, in certain cases. It should therefore be understood thattheinvention is not limited to either of these features separately or to both in combination, but that the invention is defined solely by the following claims.

I claim: b 1. In a machine having a table, a mechanically driven cutter and a work guide, means for supporting said guide and other means separate from said guide for guarding the entire unused portion of the cutter and simultaneously unyieldably supporting the work guide against springing laterally due to a workpiece. V 2.
