Specification of Letters Patent.

Patented April 14, 1908.

Application filed October 14, 1907. Serial No. 397,279.

To all whom it may concern:

Be it known that I, JAMES YOUNG, citizen of the United States, residing at VVoonsocket, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Turning-Machines, of which the following is a specification.

My invention pertains to wood turning; and it contemplates the provision of a machine designed more especially for turning wood bobbins and analogous articles, and constructed with a view of automatically engaging a properly placed blank, expeditiously reducing the same to the shape desired, and automatically releasing the turned article so as to permit of the ready removal thereof. In other words my invention seeks the provision of a wood turning machine which by reason of the automatic action of its parts leaves nothing for the operator to do but to place the blanks between the centers and remove the articles from the machine subsequent to the turning operation.

The invention also contemplates the provision of a wood turning machine embodying simple and efficient means through the medium of which the working parts may be easily and expeditiously stopped at any time to prevent injury thereto in case of accident.

Other advantageous features of the invention will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this specification, in which:

Figure 1 is a plan view of the machine constituting the best embodiment of my invention known to me, Fig. 2, a front elevation Fig. 3, a rear elevation; Fig. 4, a detail, longitudinal, vertical section with the parts in the positions they occupy when the centers are in engagement with a blank or piece of stock; Fig. 5, a similar view with the parts in the positions they assume after aturned article has been knocked off the centers; Fig. 6, a transverse section, taken on the line 66, of Fig. 1; Fig. 7, an enlarged detail showing certain cams and the clutch of the machine Fig. 8, an enlarged detail illustrative of the headstock center and the knocking oif mechanism; Fig. 9, a transverse section taken in the plane indicated by the line 99 of Fig. 8; Fig. 10, a detail, horizontal section, taken in the plane indicated by the line 1010 of Fig. 9.

Similar letters and numerals designate corresponding parts in all of the views of the drawings, referring to which:

C is the bed of my novel machine A, a frame fixed to and rising from the bed; B, a frame rising from the bed and adjustably fixed thereto; M, a longitudinally-disposed drive shaft, journaled in suitable bearings at the rear of the bed O and provided at its inner end with a pinion j and at its outer end with a stepped pulley T designed to be connected through a belt (not shown) with an ordinary countershaft; O, a transverse shaft journaled in suitable bearings on the bed and provided with a spur gear i and cams s s a and p; N, a shaft journaled in bearings on the bed; It, a miter gear fixed on shaft N and intermeshed with the pinion of shaft M and carrying a clutch member 107 at its inner side; V, a sleeve loosely arranged on and movable in the direction of the length of the shaft N and having a gear 110 intermeshed with the gear i of shaft O and also having a clutch member 108 at its outer end complementary and opposed to the clutch member 107 of miter gear k,- and V a hand lever, fulcrumed at w on the bed O and having a bifurcated lower end disposed in a circumferential groove 109 of the sleeve V.

Certain of the working parts of my novel machine derive motion from the shaft O, as will be presently described, and motion is transmitted from the continuously rotating shaft M to the shaft O through the gear j, the gear K, the sleeve V, its gear 110 and the gear 11 so long as the clutch member 108 is in engagement with the clutch member 107. V hen, however, the sleeve V is moved through the lever W to carry the clutch member 108 inward away from the member 107, the shaft O and the parts operated thereby will stop. The lever W may be quickly and conveniently operated for the purpose stated and in that way the parts operated from the shaft O may be stopped at any stage in the operation to prevent damage thereto in the event of an accident. Said lever XV may also be quickly and easily operated to engage the clutch member 108 with the clutch member 107, and so long as the said members are in engagement the shaft O will be rotated from the continuously rotating shaft M.

D is a live head stock spindle, journaled in suitable bearings in the frame B and provided with a center W and a stepped pulley E the latter bein designed to be connected with a countersha t (not shown).

U is a lon itudinally-disposed bar connected to the inner end of the frame B and having a reduced forward portion and a beveled or inclined shoulder 104 on its lower edge immediately in rear of the said reduced portion.

D is a longitudinally-movable tail stock spindle arranged in the frame A and having a center W at its inner end; v, a V-shaped support for blanks, arranged below the inner ortion of the spindle D and fixedly connected through a rod Q with the inner end of the fixed frame A; Y, a longitudinally-disposed, horizontal rod fixedly connected through a hanger a" with the spindle D 0;, an upright fixed, preferably in an adjustable manner on the rod Y and having means such as an eye 00 at its upper end loosely receiving the spindle D; o, a vertically-movable, V- shaped support for blanks or pieces of stock, loosely connected with the upright :0 through the medium of a screw 100 (Figs. 810) and having a lateral arm 101; 102, a lateral arm on the upright :r, from which rises a post 103, loosely arranged in the lower end of the stock support 12; and n, a coiled spring surrounding the post 103 and interposed between the arm 102 of upright a: and the lower end of the support 22 and having for its olfice to yieldingly maintain the said support 12 in the raised position shown in Fig. 5.

In the operation of my novel machine, the square or rough turned blanks or pieces of stock, which usually have longitudinal-central bores, are placed one by one in and removed from the V-shaped portions of the supports 22 and o by the operator, and they are each knocked on and knocked off the center as follows: l/Vhen the head-stock spindle D is moved inward by means presently described, the end of a blank or piece of stock, previously placed on the center and in the supports 12 and Q), will be forced on the center W of the live tail-stock spindle D so as to turn therewith. On the said inward movement of the spindle D, the blank or piece of stock will be moved thereby off the support '0, which is fixed with respect to the fixed frame A and at the same time the rod Y, the upright 90 and the support 1) will be moved in the same direction as the spindle D, whereupon, by reason of the arm 101 of the support 12 moving over the shoulder 104 and against the lower edge of the wide portion of the bar U, the support 2) will be drawn downward and away from the blank or piece of stock, leaving the latter free to turn on the centers W and W. This operation of knocking on takes place before the blanks or piece of stock is turned by the means hereinafter described to the shape desired, and after the turning operation, the article is knocked off as follows: On outward move ment of the spindle D, effected by means presently described, and the synchronous movement of the rod Y and the upright 90, said upright 90 will force the turned article off the center W and the article will drop on the supports 0 and 1), ready to be taken away by the hand of the operator. Meanwhile, the arm 101 of the support 1) will have moved to a position below the comparatively narrow part of the bar U, and the spring n will have raised the support '0 to the position shown in Fig. 5, ready to receive a fresh blank or piece of stock from the hand of the operator. At this point it should be noted that during the operation of the machine, all the operator has to do is to place the blanks or pieces of stock one by one on the supports 1) and o and remove the turned articles from said supports, and consequently the operator is free to use one hand to place blanks in position and the other hand to remove turned articles. This will be appreciated as an important advantage when the rapidity with which the turned articles are produced is considered.

The described inward, endwise movement of the spindle D is effected by the cam s on the shaft O engaging an anti-friction roller 2 on a lever P fulcrumed on the bed C and connected to the said spindle D, Fig. 5, and the following outward, endwise movement of the spindle D is caused by the cam s on shaft 0 operating against anti-friction roller 2 on a lever P which is also fulcrumed on the bed C and connected to the said spindle D.

H is a frame arranged transversely on and fixedly connected to the bed C. G G, Figs. 1 and 6, are parallel, longitudinal rails mounted on said frame H, and F is a tool carriage, movable on said rails in the direction of the length of the machine. The said carriage F is moved toward the right by the mechanism shown at the right of Fig. 2 and toward the left by the mechanism illustrated at the left of Fig. 2. The first mentioned mechanism comprises a rod n, pivotally con nected at m to the carriage F and preferably adjustable as to length, a lever K fulcrumed at 117 on an adjustable bracket w connected with bed C and having its long arm connected at f to the outer end of the rod 12. and also having a preferably adjustable, anti-friction roller 1 on its short arm 118, and the before described cam p on the shaft 0, which cam is arranged to engage said roller r. Incident to rotation of the said shaft 0 in the direction indicated by arrow, the cam p cooperating with lever K will obviously move the carriage F in the direction indicated by the arrow on said carriage, and then move out of engagement with the lever K, leaving the latter free to swing in the opposite direction. The second mentioned mechanismfor moving the carriage F comprises a cable 120 attached to the carriage and passed over a sheave p on the bed C, and a spiral spring C connected to the cable 120 and designed to be fastened to the floor or at any other suitable point. The latter mechanism serves to draw the carriage F in the direction opposite to the arrow on the carriage, Fig. 2, after cam p passes out of engagement with antifriction roller 1*, and the spring C in said mechanism is preferably a slack coiled spring which is advantageous since it loses power as it approaches its normal position of rest, thus drawing the carriage F to the starting point with much less force than if a weight were employed for the purpose, for the weight would gain speed in proportion to the length of its drop.

The movement of the carriage F toward the left in Fig. 2 is limited by a stop I) in the form of a plunger mounted in a guide b and backed by a spring, an air cushion or other posed under said ways 121.

suitable means; the said guide I) being preferably carried by a bracket (Z, adj ustably c011- nected to bed C.

Mounted u on and suitably connected to the carriage F is a tool post or supportin frame S in which is a shaft 111 on which too holders t are pivotally mounted. Tools 9 and 10, Figs. 1 and 6, which are shown as roughing tools but which are not necessarily of that type, are arranged in the holders t upon bars 112 and are adjustably fixed in the holders and upon the bars 112 by binding screws 1 and 2 bearing in the tops of the holders and against the tools. Posts J, Fig. 6, arranged beneath the inner ends of the bars 112 and connected to the frame S, serve to limit downward movement of the cutting ends of the tools 9 and 10, and the said bars 112 are normally held against the posts J by spring strips 113, Figs. 2 and 6, which are connected to the frame S and bear upward against the outer portions of the bars 112 and thereby yieldingly hold the cutting ends of the tools to their work.

J is a longitudinal guide arranged at the front of the machine and carried by brackets I connected to the undersides of the rails G. The said guide cooperates with rollers h on the outer ends of the tool supporting bars 112 to guide by its irregular shape the tools 9 and 10 when the carriage F is moved in the direction of the arrow thereon in Fig. 2, and in that way enable the said tools to shape the work thereby relieving the finishing tool of heavy cutting.

The transversely arranged, fixed frame H is provided with undercut ways or grooves 121, Figs. 2, 3 and 4, and on said frame is arranged a carriage L, movable transversely of the machine and having tongues 122 dis- At its outer end the carriage L has a bracket 7 in which bears a screw 123, arranged to engage the rear end of the frame H with a view of limiting the inward or forward movement of said carriage and the tool, presently described, carried thereby. Arranged on the carriage L and secured thereto by bolts bearing in flanges 124 and engaging one end of the carriage, Fig. 3, is a frame 124 having a longitudinal, vertical portion 125 in which is a longitudinal, horizontal slot 126. The said portion 125 is for the connection of tool holders 127 and 128, preferably of general right-angle form; the connection being affected through bolts secured in the said slot 126, Figs. 3 and 6. The outer or rear horizontal portion of the tool holder 127 is supported by bolts 5 and 6 connected to the holder and bearing on frame 124, and consequently the finishing tool 11, connected to the holder 127 through bolts 129 or other suitable means, may be conveniently adjusted and adjustably fixed with respect to the frame 124 and the carriage L.

The carriage L is translated or moved inward and outward on the frame H by the following means: On the underside of the said carriage L is a rack R, Figs. 4 and 6, with which is intermeshed a sector gear 12, fixed on a longitudinally-dis osed shaft 13, journaled in bearings carried by frame H, and the said shaft 13 is provided with a crank arm 15, connected through a link 14 with a lever K which is fulcrumed loosely on the transverse shaft N and is provided with a weight w and an upwardly reaching portion 10 bearing an anti-friction roller .2. This latter is arranged to be engaged by the before mentioned cam it on the transverse shaft 0, and the o )eration of this portion of the machine is as follows: During rotation of the shaft 0, the cam u acting against roller 2 raises the weighted end of lever K and depresses the opposite end thereof, and causes the latter end, through the link 14 and crank arm 15, to rock the shaft 13 and sector gear 12 in the direction of the arrow in Fig. 6, and through said sector gear and rack R move the carria e L inward so as to carry the finishing too or tools into engagement with the blank or piece of stock on the centers. When the cam u moves out of engagement with the roller .2 of lever K, the weight w rocks the lever in the direction opposite to that just mentioned and through the medium of the mechanism described moves the carriage L and the tool or tools thereon outward or away from the blank or piece of stock on the centers.

During the practical operation of the machine, it will be understood that all the operator has to do is to place blanks on and remove turned articles from the supports v and o, and that by manipulating the lever W, the operator is enabled to quickly stop all of the parts that derive motion from the shaft 0, and in that way prevent damage to said parts in the event of accident. It will also be understood that the blanks are placed one by one on the su ports '0 and v and on center W by the hand of the operator while the parts are in the position shown in Fig. 5; the V shape of the supports serving to guide the blank to center, and as the shaft 0 continues to rotate the cam s thereon serves through the mechanism described to throw the tailstock spindle D inward with the result that one end of the blank will be forced upon the live center W and caused to turn therewith, and at the same time the support 12 will be drawn down away from the blank. During the knocking on described, the carriage F is held by spring C against the stop I), and when the blank begins to turn freely on the centers, the cam p on shaft 0 engages roller 1 on lever K and through the connection described moves the carriage F toward the right in Fig. 2 to enable the tools 9 and 10 to do the rough cutting and shape the blank. Then when the cam p passes out of engagement with the rollerr, the carriage F is re turned by the means described to its position against the stop I). The movements of the parts are so timed that immediately after the movement of the carriage F toward the right, 'i. a, in the direction of the arrow in Fig. 2 of the drawings is completed, the cam u on shaft 0 will engage the roller .2 of lever K, and said lever will be rocked so as to move the carriage L inward and the finishing tool or tools thereon into contact with the blank. On disengagement of the cam u from roller .2 and during or immediately after the outward movement of the carriage L, the cam s on shaft 0 engages the roller 2 on the lever P to throw the tail-stock spindle D outward,

when the center W of said spindle will be disengaged from the finished article, and at the same time said article will be displaced from the center W by the means described and caused to drop in the supports 1; and e.

The operation described requires approximately six seconds, and as the operator has nothing else to do he can remove the turned articles from the supports 1) 1) with one hand and place blanks on the supports with his other hand, and thus keep up with the speed of the machine.

When articles other than bobbins are to be turned, it is obvious that various tools may be substituted for those herein shown and described.

The construction herein shown and described constitutes the preferred embodiment of my invention, but it is obvious that in the future practice of the invention such changes or modifications may be made as fairly fall within the scope of the invention as defined in the claims appended.
