vTo all 'who-m it muy concern:

Be it known that I, CHARLES H. NoRToN,

citizen of the United States, residing at I Worcester, .in the county of Worcester and State of l'assachusetts, .have invented a new and useful Grinding-Machine, of which the following is a specification.

chine and particularly to a type of vmachine in which the grinding Wheel-is driven from below. the grinding head.

Many of the Vfeatures of my invention hereinafter described are particularly useful and valuable When used 1n a grinding Y machine of the universal type, but other fea "tures are also of'gre'at value when used in a plain grinding machine and I do not wish to be limited to a'particular type of machine,-

othervvise than as set forth in the claims.

it is the usual practice in universal grinding machines to support the grinding Wheel upon a wheel head Which is angularly adjustable upon a Wheel slide.

. slide is mounted for longitudinal movement i" upon a slide base which, in turn, is anguruns to and from the Wheel. shaft, the line of each run being closely adjacent, to the axis above mentioned.

`lo the accomplishment of the above ob-.

ject, 1 'provide an annular gear rotatably mounted. upon the frame and a rack upon the Wheel slide. This gear and'. rack constitute means for moving the wheellslide longitudif nally when in any angular position'and the annular gear is providedfvrith an axial opening through which the Wheelis driven.

lhen the invention is embodied in' a plain grinding machine, simpler/devices for moving the Wheel slide may be substituted for the annular Vgear and rack but the' method of driving the Wheel by driving means extending upwardly through an opening the- The Wheel lower part of the Wheel slide is still advantageous.

Further objects of my invention are the provision of improved devices for alining the Wheel shaft with the Work centers, and also the provision of an internal grinding atvtachment on a universal grinding machine. This invention relates to a grinding ma- With lreference to the latter object my invention consists in providing an auxiliary grinding shaft on the/'rear end of thevvheel head and in providing for the driving of silidf auxiliary shaft from the main grinding s a t. I With these and other objects in view my invention also consists in certain devices, arrangements and combinations of parts which vvill b ehereinafter described and more particularly pointed out in the appended claims. A preferred form of my invention is shown in the dra'Wings,'in Which- Figure 1 is a side elevation of a universal grinding machine With parts of the Work table shown in section; Figs. 2 and 3 arev a top plan View' and elevation respectively of the Wheel head and the Wheel driving mechamsm, drawn on an enlarged scale; Fig. 4 is a detail sectional view of the devices for moving the wheel slide longitudinally, taken on a plane normal to the planeof Fig. l3; Fig. 5 is a detail sectional view of one of the bearings for the Wheel shaft; Figs. 6 and 7 are side and end elevations respectively of the take-up guide pulley; Figs. 8 and 9 are side and end elevations respectively of the swivel guide pulley; Fig. 10 is a sectional view taken along the line lO-lO of Fig. 8. Fig. 11 is an enlarged detail view of certain of the parts shown inFig. 10; Fig. 12 is a longitudinal view taken along the line 12-12 in Fig. 1 and showing parts of the driving mechanism; and Fig. 13 is a partial side elevation taken alongfthe line 13-13 in Fig. 12.

Referring to Fig. 1, 1 have shown the Wheel head mountedy upon a frame 2O which supports-also a Work table 21 having Work centers 22 secured thereto in any usual man'- ner. Suitable devices (not shown) are provided for moving the Work table 21 longitudinally, these devices being'driven from the pulley 23 shown in Fig. 12S The grinding'wheel W (Fig. l) is mounted` upon a' Wheel shaft 30 (Figs. 2 and 3) which is supported in hearings. seeured` to thewheel head 32.*' The wheelfhead .32 is mounted to swivel upon a wheel slide 33 which 'is .longitudinally movable upon the slide base 34.

The wheel slide is provided upon its lower face with an inclined guiding surface 35 (Fig. 4) and also has a rack 36 secured thereto. The inclined surface 35 and the vertical face of the rack 36 coperate witlranf .upwardly extending rib 37 upon the sllde base to guide the wheel slide in its longitudinal movements.

l The slide base 34 is angularly adjustabl upon the frame 20, being held in adjusted angular position by bolts 38 (Fig. 4) moving in a T-slot in the frame. The wheel head 32 is similarly retained in adjusted angular position uponthe wheel slide 33 by bolts 39, the heads of which move in a T-slot 40 in the slide 33. The angular adjustment of both the wheel head and the slide base is laccomplished by loosening the bolts 38 or l shaft extends'to the front of the machine and is provided with a hand wheel 46 (Fig. 1) by means of which the slide 33may be manually moved longitudinally. It will be obvious that the rack 36 is at all times in mesh with the gear 41 regardless of the angular position of the slide base.

In the lower part of the frame 20 I provide a power shaft 50 (Figs. 1 and 12) suitably supported in bearings 51 and v52 (Fig. 12) and provided with a driven pulley 53 which may be connected by a suitable belt to any convenient source of power. A driving drum 54 is secured to the shaft 50 within the frame 20 and constitutes means from which the grinding wheel is driven.

The connection between the driving druin 54 upon the shaft 50 and the driven pulley 55 (Fig. 2) upon the Wheel shaft 30 consists of a belt 56 (Fig. 1) passing around the drum 54 and thence upwardly past an elongated guiding pulley 57, through the opening in the annular gear 4l, and -around guiding pulleys 58 and 59 to the driven pulley 55 upon the wheel'shaft 30. The belt 56 thereafter passes around the fixed guiding pulley 60, down through the annular' gear 41 to the elongated guidingy pulley 61 mounted ad" jacent to the guiding pulley 57 and thence to the driving drum 54.

With this arrangement of guiding pulleys, best shown in Fig. 1, the beltpasses to and from thewheel head in closely adjacent par- -allel runsfvthich are positioned substantially inafter described.

pulleys 57 and 61 are rotatable upon sleeves 62 secured to non-rotatable shafts. 63 Xe'd in a casting 64sup'ported upon an inward `v'..1i"'f v7,5

extension of the bearing 51. The casting 64 is keyed to the extension of the bearing and supports the two shafts 63 in parallel relation as shown in Fig. 1.

Attheir outer ends the shafts 63 are provided with caps 65 which include means for oiling the pulleys 57 and 61. The oiling means comprises an oil 4cover 66 pivoted to each cap and closing the end of a passage 67 extending into the shaft 63 for a portion of its length and communicating with an oil pocket 68 within the sleeve 62. l The guiding pulley 60 (Figs. 1 and 3) in the wheel head 32 is mounted upon fixed bearings and guides the belt as it passes from the driven pulley 55 downward to the guiding pulley 61 and the driving drum 54.

The guiding'pulley 58 is rotatably mounted on a depending arm 70 (Fig. 8) formed i upon the end of a cylindrical sleevev 71.-

The sleeve 71 is supported in a bearing in the head 32, as shown inv Fig. 3, a shoulder 72 on the sleeve, positioning it longitudi-y nally in one directin and a nut 73 threaded upon the opposite end of the sleeve preventing its displacement in the opposite direction. The pulley 58 is thus; free' to swing about the axis of the sleeve 71 4as 'a centerf and may accommodate itself to the' varying angles at which the driving belt 56 ap? preaches the pulley.,

The guiding pulley 59 (Figs. 6 and 7) is mounted on a bearing supported upon the end of a sleeve 74. The sleeve has a key Way 75 formed in one side thereof and has a plurality of rack teeth 76 cut or inserted in the opposite side. The sleeve 74 is mounted'within the sleeve 7l` previously described and is prevented from moving a'ngularlyl relatively thereto by a key or pin 77 (Fig.'-11r5fl The depending arms upon the sleeve '7l- A 8) extending into the keyway 7 5.

upon its inner end for purposes to be here-4 A collar 85 is fixed to the end of the rod 80 and a coil spring 86 surrounds the rod between the collar and the-bearing,78 and 7o same width of face as the drum 54. The

normally forces the rod to the right as viewed in Fig. 11.

-sleeve 81, while the clutch teeth89 under `other conditions mesh with clutch teeth 90 formed upon a cylindrical extension 91 of a spring barrel 92 (Fig. 10). The extension 91 is rotatable within the bearing 79 and provides a bearing or support for the left hand end of the rod 80.

A fiat or ribbon spring 93 is coiled within 'the barrel 92, having one end secured to the 'inner face of the barrel and having the opposite end secured to the non-rotatable rodv 80. The barrel 92 is movable longitudinally with the rod 80 but is rotatable thereon under the influence of the spring 93. As the coil spring 86 (Fig. 11) slides lthe rod 80 to the right in said ligure, the clutch teeth 90 upon the extension 91 of the barrel 92 engage the clutch teeth 89 upon the pinion 87.

The ribbon spring 93 is so disposed that it tends to rotate the pinion in the direction indicated by the arrow in Fig. 8, thus acting to force the sleeve 74 rearwardly andl carrying the guiding pulley 59 in the same direction. The pulley 59 thus acts as a take-up pulley under the tension of the spring 'i 93 and is adapted to be yieldingly moved longitudinally, thereby adjusting the effective length of the belt 56 to the varying positions of the wheel head 32 and the slide 33.

. If it is desired to vary the tension of the spring 93, it is merely necessary to.push the `rod 80 to the left, as viewed` in Fig. 11,

against the pressure of the spring 86. This movement of the rod 80 will disengage the clutch teeth 90 from the teeth 89 and will at the Sametime engage the teeth 84 with the teeth 88.

As the teeth 84 are forn ed upon the nonrotatable sleeve 81, the inion 87 is thus locked against rotation, vhile at the Same time the spring barrel 92 is released and may be turned manually `to place any desired tension upon the spring 93. When the desired tension is attained, the rod 80 is permitted to move to the right to its normal position, the teeth 90 again engage the teeth 89, and the spring 93 is connected to rotate the pinion 87 -as above described.

- It should be` noted that the driving belt in passing lfrom the guiding pulley 59 to the driven pulley 55 passes through the center of the sleeves 71 and 74, and also that the pulleys 57 @d 61 in the frame 20 cooperate with t e pulleys 58 and 60 in the head 32 to gui e the belt in closely adjacent parallel runs, eachA normally substantially in either direction.

coincident with the aXis of the annular gear 41.

If the slide base 34 is so adjusted angularly that the -wheel slide 33 travels at right angles to the work table 21 and to the shaft 50, the parallel runs of the belt 56 will swing forward and backward about the pulleys 57 and 61 as centers, the varying distances between the several pulleys belng provided for by the longitudinally movable take-up pulley 59. The opening in the annular gear 41 is of such diameter as to permit this forward and backward movement. within. the limits necessary for the practical operation of the machine. lf, `on the other hand, the slide base 34 is angularly adjusted so that the slide 33 will move parallel to the work table 21 and to thev shaft 50, the driving belt will follow the movement of the slide and will travel from yend to end of the drum 54 and the elongated guiding pulleys 57 and 61, the open- 'ing in the annular gear 41 similarly per- The wheel head 32 is shown in its normal. l

position in Fig. 1 and is adjustable upon the slide 33 through an angle of 180 degrees The head may thus be exactly reversed upon the slide if desired, the driving belt then becoming a cross belt instead of an open belt. Y

Upon the rear end of the head 32 I provide bearings 100 (Fig. 2) for an auxiliary grinding shaft 101. This shaft is provided with a driven pulley 102 upon one end and has means for supporting a small grinding wheel 103 upon the opposite end, the auxiliary grinding shaft being particularly adapted for internal grinding. When it is found desirable to use this attachment, a driving pulley 104 is mounted upon the main shaft 30 and is connected by a belt 105 with thepulley 102.

matter of great convenience when it is desirable to perform both eXtei-nal and internal rindinO' u on the same niece of work without changing the position of the work upon the work centers. m

In all cylindrcalgriiiding machines it is Zontal plane of the work centers.

of the greatest importance that the grinding shaft should be located exactly in the hori- If the shaft'is located in a parallel plane either above or below the centers, it will be impossible to grind a straight Vtaper upon work held4 on the centers, while'the location of the shaft in a plane at an angle to the plane of the centersl makes it impossible to grind either cylindrical l or tapered work accurately.

In order to -facilitate the exact location of the grinding wheel shaft with reference to the work centers I have provided special bearings which will be'now'described. Each bearing consists of a split tapered sleeve 110 (Fig. 5) provided with undercut tapered recesses 111 and 112 at the ends of the tapered portion of the bushing. This sleeve is supported in a tapered hole in a box or casing 113 having externally threaded portions upon its opposite ends. A nut 114 is provided to ft upon the screw thread at one end of the casing 113 and upon its inner face the nut has a tapered projection 115 adapted to fit into the tapered recess 111.

, A similar nut '116 is. mounted upon the opposite end of the casing 113 and is provided with a tapered projection 117 fitting into the recess 112. VWith this construction it will be evident that by loosening the nut 114 and tightening the nut 116 the split sleeve 110 can be moved longitudinally with relationfto the casing 113. This longitudinal movement will necessarily contract .the sleeve to the desired relation with the shaft 30. When .the sleeve is properly positioned longitudinally, the nuts 114 and 116 may be tightened to firmly clamp the sleeve inv the casing 113, the tapered projections 115 and 117 forcing the split sleeve 110 firmly into contact-with the casing113.

Upon its exterior the casing 113 is provided with a plurality of angularly disposed fiat surfaces 120 (Fig. 3). The head 32 has a pair of similarly disposed surfaces 121 l for each bearing and is also provided with clamps or caps 122 having angularly disosed surfaces 123 upon their lower faces. ach clamp 122 is-secured to the head 32 by a screw 124, and is laterally positioned upon the head by bearing surfaces 125 and 126'. With the casings and their supporting surfaces constructed in this manner it is a Amore of the surfaces 120 and 121 until the shaft is exactly alined. Similar provision is made for thel alinement and adjustment of the auxiliary grinding'shaft 101. V

- The operation of my machine has been indicated in connection with the detailed. description of the several parts and further description thereof is considered unnecessary.

When my improved construction for driving the grindingwheel is used in a plain machine the swivel pulley 58 may be arranged as a iixedpulley similar in all lrespects to the pulley 60, while the 'slide for the take-up 'pulley 59 and its operating mechanism may bemounted directly upon the wheel head instead of upon the rotatable sleeve 71. Simplerdevices of well known construction, such as a screw upon the shaft 45 and a nut projected downward from the wheel head, will serve to move the head longitudinally. The wheel slide may be merged with the wheel head vand the slide base may be formed integral with the frame of the machine. WVith 'these changes the take-up and guide pulleys perform their functions as previously described and an extremely simple self contained belt drivenmachine results. Y

It will be apparent that other driving connections may be substituted for the belt drive shown in either the universal or the plain type of machine, without losing many of the advantages shown and described. It

. will also beevident from the foregoing description that many other changes and modiin the art without departing from the spirit and scope of my invention as set forth in the claims and I do not wish to be limited to the details herein disclosed, but
