SPECIFICATION forming part-of Letters Patent No. 517,705, dated April 3,1894. Application tiled December 29, 1892. Serial No. 456,631- (No model.)

To @ZZ whom it may concern:

Be it known that I, HENRY W. MORGAN, of Rochester,`in the county of Monroe, in the State of' New York, have invented new and useful Improvements in Growing-Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.A

My invention vrelates to improvements in grooving machinesparticularly designed for cutting the grooves in the ends of boards. or shooks'for'forming boxes having their corners joined together; and to this end it `consists, essentia1ly,'in a frame, a carriage movable upon the frame, a bearing movable toward and awayl from the carriage, a Acutterhead j ournaled in the bearing, and having its laxis disposed vin a plane at substantially righti had to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding ,parts in all the views. Y

Figures 1 and 2 are respectively top plan View and front elevation of my improved invention, illustrating the general construction and arrangement of itsv component parts. Fig. 3 is a transverse vertical sectional view, taken on line -3-3-, Fig..2. Fig. 4 is an enlarged horizontal sectional vview of the central portion of theparts as shown at Fig..1, taken on line -et-4, Fig. 2. Fig. 5 is a vertical section al view, taken on line '-5-5-, Fig. 4t. Fig. 6 is a rear elevation of the parts as shown at Figs. 4 and 5. Fig. 7 is a trans- -verse vertical sectional view, taken on line -7-7,, Fig-1, the upper portion of the rear clamping jaw and the lower portion of the frame and the cutter-head shaft bein g broken away. Fig. 8 is a transverse vertical sec.

tionalview, taken on line -f88-, Fig. l, looking toward the left-hand, thel frame being omitted. Fig..r9 is an enlarged vertical sectional View, taken on line -9-9-, Fig. 1.

Fig. 10 isa 'similar vertical sectional view, taken on line -10-10*, Fig. l. Fig. 11 is a vertical sectional view, taken on line --11- 11-, Fig. 1, illustrating particularly the ball bearing for supporting the weight of the cntter-head and its shaft. Fig. 12 isa detail vertical sectional view, taken on line-12--,12-, Fig. l, illustrating the ear on the cutter-head bearing for receiving the screw that shifts said bearing toward and away from the carriage. Fig. 13 is a top plan view of a detached portion of the cutter-head bearing and theY gage larranged at one side of the support and carriage. Fig. 14 is averticalsectional view, taken online -14t-14-, Fig. 13. Fig. 15 is a detail sectional view ofthe adjustable bearing for one of the idlers around which the drivingbeltis passed. Fig. 16 is a vertical sectional view, takenfon line 16- 16, Fig. 1.V Fig. 17 `is a detail horizontal sectional view of a portion of the feeding head shafts, the actuating belt passed around l said pulleys, the driving wheelsfor moving said belt,and the idlers -for supporting and guiding the belt. Fig. 2.0 is a top plan view of one of the detached saws composing the cutterheads. Fig. 2l is an isometric perspective of an ordinary box having theadjacent ends of its si'desj oined together. Fig-22 is an isometric perspective of a similar box provided with a sliding cover. Fig. A23. is a detail view showing one of thelongitudifnal sides of thev box illustrated at Fig. 21 and thedetached cutter-heads andthe box shook supports as in their operative position assumed when the ends of said side are being grooved. Fig. 24 is a similar detail view showing one of the longitudinal sides of the box illustrated at Fig. 22, and the ICO of the parts shown in Figs. 18 and 19, the idlers being moved into alignment with the rear driving pulley and the belt being shown as wound around said idlers when in said position.

The frame -A- may be of any desirable form, size, and construction, and is formed with standards orlegs -ct-, a crosswise guide -cL'-, and a lengthwise guide -a2--. The guide aconsists of separated horizontal shoulders -a3-ct3, separated upright shoulders a4-CLL at the outer edges of the shoulders a3-p3, and gibs or top shoulders ot5a5 arranged above and projecting beyond the shoulders a4--a4-- The guide a2-w consists of lenthwise ribs or shoulders -aG--LLL- arranged along the tops of the longitudinal sides of the frame above the shoulders -c--a-Q.

riage -B- formed with lateral shoulders- The gear wheel -C5, as shown at Fig. 17, is lods'e upon the shaft -C-, and is formed with a hub #011-, which projects from one of its faces and is formed with a shoulder wizand the gear wheel C4- revolves loosely upon the hub *C11- on the inside of the shoulder -C12. The gear-wheels -Cid- C5V are formed at their outer faces with the respective clutch sections C7-C8# for engaging clutch sections C9-C10- fixed upon the left-hand end of the shaft -C-, which is movable lengthwise in its bearings AL-A2- for alternately engaging the clutch sections CL-CL and dGB-- llo. When,as illustrated at Fig. l, the clutch section -C8 is engaged with the clutch section C10, the pinion -C3-, which revolves in the direction indicated by arrow -lat Figs. l and 2, is engaged with the gear Wheel C5-1 and drivesthe shaft -C- in the direction shown by arrow 2 at Figs; l and 2, thus feeding the carriage B to the rear of the frame A`-, owing to the engagement of the pinion"`CG with the rack teeth -bupon the carriage. During this engagement of the pinion C3- and the gear wheel -C5- the gaged with the pinion -C2-\on the driving shaft or spindle -C-, revolves loosely on the hub C11- of the gear wheel -C5. As soon as the shaft -O is moved lengthwisely, so as to engage the clutch section C9- with the clutch section -07- on the gear wheel -CL- and to disengage the clutch section C10- from the clutch section -C8-, the shaft -C- is, as is evident to one skilled in the art, revolved in a reverse direction for feeding the carriage -B-- forwardly. These clutch sections -CS-CO- and C7-Cilare so relatively arranged that one pair of said clutch sections may be entirely disengaged without the engagement of the other pair in order that both gear-wheels -C4-C5- may be revolved loosely on the shaft -C- by the pinions m(ll-C3- without affecting the revolution of the shaft -C-. It is evident, however, that, as the shaft -C is moved lengthwise in either direction from its position assumed when neither pair ot the clutch sections is in engagement, one pair thereof is brought into engagement, and the shaft -C-- is then revolved either forward or backward.

The driving shaft or spindle C may be revolved by any suitable construction of power transmitting mechanism, here shown as a link belt cpassed over the sprocket wheel 0'- upon the driving shaft orlspiudle -C- and over the sprocket wheel --c2 upon a spindle -D-,a belt -Cmrunning over pulleys d--CM---Ci-f mounted respectively upon the spindle --D and a second spindle D-, and a belt -C2O passing overa pulley -CGH upon thespindle-D-, and a pul ley C17- mounted upon the main driving shaft -7c-. Upon this shaft 7eare tight and loose pulleys -CB--Cg-,to which power is transmitted by any `suitable construction of power transmitting mechanism, not necessary to herein illustrate or describe.

As previously stated the shaft -C- may assume such a position that the bevel gearwheels n(J4-05M revolve loosely thereon without effecting the revolution of said shaft, and I preferably provide my invention with an automatically operating shifting device by the position of the carriage -llfor forcing the shaft to said position when being revolved either in the direction shown by ar rows-2 at Figs. l and 2 for feeding thecar riage rearwardly, or in `the reverse direction for feeding the carriage forwardly. This shifting device consists of a lever -cpivoted at nc7 to an arm -A3- on the frame -A and formed with an arm -c5 for engaging a pair of faces or pins eL-c4 upon the carriage B. The lever -c6- is provided at one end with a lug -osengaged with a grooved collar -c"- fixed upon the shaft -C' and at its other end with a hand engaging portion -c3.

lVhen the carriage is feeding rearwardly, owing to the engagement of the clutch sections -CRC10- the parts of the shifting device for the feeding-mechanism of the carriage are in the position shown at Fig. 1. As

ICO

IIO

the carriage Br-- reaches the limit of its rearward movement, the front pin or face c4 engages theend ofthe arm -c5- and rocks said ar'm backwardly toward theframe A into a plane substantially parallel with said frame -A- and thereby swingsthe lever -cupon its pivot, so as t movethe y shaft OL-'lengthwisely within its bearings A2-A2'- asufflcient distance to disengage the clutch sections -O8-C10- without engaging the clutch sections -O7-C9. The shaft -C-' then stops its revolution andthe rearward feeding-of the carriage -B- is aul *Cf-'thenrevolves ina reverse direction from that indicatedby arrows -2 at Figs. l and 2, and feeds the carriage forwardly until the rear pin or face c4 engages the end of the arm -05- and automatically rocks the lever c6 in an `opposite direction vto that in which it `was rocked by the engagement of the forward piny ctvwith. the arm-c5- and thereby disengages the clutch sections G7-(Wm` forstop ping theforward movement of said carriage. When desired to again feed the carriage rearwardly the-operator rocks the lever -cto its position shown at Fig. l, and engages the clutch sections -C8-C10-. It is Afrequently desirable .to feed the carriage Bby hand, and accordingly7 I provide upon the right hand end of the shaft -C'-.a hand engaging wheel or piece --C21-, Whichmay be readily engaged for rotating the shaft -C- when in suchl position that neither pair of the clutch sections -C-CQ- and -fCS-Cloare engaged. This particular construction ofm echanis'm for feeding the carriage -B- backwardly and forwardly and for automatically disengaging the feeding mechanism so as to prevent itsaction, is very simple in construction, practical and effective in operation, and durable in use.

Movable along the guides T642-, upon opposite sides of the carriage B are bearings -e-e`-, which are of any desirable form, size, and construction suitable for supporting the shafts i-ee-e of the Acutter-heads -E-E-. The bearings ,he-e-are, as best yseenfatrFig. 7, formed with separated faces -e2-e2 bearing upon .the top faces of the ribs -ct-aof the guide -agand are formed with longitudinal shoulders -eS--esbearing againstthe under faces of said ribs a6 as screw F-, which is arranged lengthwisely beneath the guide -a2- at the outside of the rear; wall of the frame-A-, and is journaled in bearings --A4-A4` projecting from said rear wall of the frame -A-f. Formed These bearings -e-e\ are moved toward and away from each other by a vjusting the distance between said cutterheads to the length of the boards .or shocks interposed between the clampingjaws presently described.

,"In order to obviate'liability of contact with the cutter-heads when removing the grooved boards, or placing Vin position boards about to be grooved I provide the bearings ,-e-ewith upright guard Walls -e-eearranged in front ofthe cutter-heads -EE-, and having their inner" edges extending almost to l,theplane ofthe inner face of the adjacent cutter-head. i u A As best seen at Figs. 2, l1,.andv20 the 'cute ter-heads e-E-E- are formed of a series of bppositely arranged circular saws E- fixed upon the shafts ,-ee-, as by splines -e7fe'7-, and provided with projecting teeth -Efhaving their front faces or edges E3- of substantially the same thickness as the groove to be formed in the ends ofthe boards or shocks. These saws are arrangedin the usual manner one above the other so that the l outer edges of the front faces E3 of the teeth of any one of the saws are slightly at one side of the vertical plane of the front edges of the corresponding teeth formedV upon the saw next beneath or above said saw. Beneath the lowery saw -E- are one or more washers Ilo' --E6.-, and above the upper saw -E- is a shoulder E7- adjustable upon `the shaft -eforrmly clamping the saws in position.

At Fig. 23 I have shown the cutter-heads as ,operatively engaged with the' adjacent ends of an interposed board-iof substantially the-,same size as either of the longitudinal sides fr-rof the box -R, shown at Fig. 2l. `It is' frequently desired to provide a box -S- with a sliding cover f- S-, as shown at Fig. 22, and in that case, theupper. tenon -sat one end of the longitudinal sides -s-sof lthe box Sfmust be formed of greater` width thanthe corresponding tenon f-SQ-e at the opposite end of the box sides. To effect this result the lowersaw Efof the cutter-head for grooving the ends to be provided with the widetenons is removed, and a washer EG- is substituted as show`n'at Fig. 24.

viate this result I support the weight of the shafts e--eby ball bearings E8-Eli These bearings may be of any desirable form, size, and construction, and are composed of opposite sections E9-E9- fitting sockets E10E1in the bearings -e-e-, sections -EU-EU- fixed upon the shafts -e'-e', and balls E12-interposed between said see tions. It is evident that, instead of the ball bearings E8 E8, any other desirable form and construction of bearings may be used.

The illustrated and described construction of the cutterheads, their supporting bearings, and the mechanism for moving said bearings toward and away from each other is also simple, practical, effective and durable.

The boards or shooks are arranged edgewise between the cutter-heads -E-E-- with their ends toward said cutter-heads, and are mounted upon the upper horizontal faces of supports -G-G-, which consist of rails secured at g r] to the bearings --ee, so as to be moved toward and away from each otherassimultaneously said bearings eeare approximated or separated. Each ofthe supports -GG is preferably provided with a movable rail or bar -G arranged at the inner side of said support and hinged at its opposite extremities to the upper ends of links GL-G2 having their lower ends hinged to downwardly extending arms -GL- G3 upon said supports. These movable rails are elevated or depressed by adjusters G4G4 secured to the forward ends of the supports -G-G-, and bearing against the forward link s *G2-*Gln and said rails are held in their adjusted position by suitable clamps GL-G5, which, in the preferable construction of my invention, consist of the bolts forming the lower hinge pins for the links G2- and nuts movable upon said bolts.

In practice the longitudinal edges of the boards or shocks to be grooved are usually supported directly upon the rails -G- G, and said rails are readily adjusted up and down to regulate the size of the tenon or groove upon the opposite extremities of the lower edges of said boards or shocks, and are then iirmly held in their adjusted position. It will be readily understood, by one skilled in the art, that after the ends of the longitudinal sides for the boxes, shown at Figs. 2l and 22, have been grooved, as shown at Figs. 23 and 24, that the lower saw -F. shown by dotted lines at Fig. 24, is replaced in position, and the adjustable rails -G-G- are then adjusted upwardly to the position shown at said Figs. 23 and 24, whereupon the boards for forming the end sides of said boxes are then placed upon the supports G'-G' and grooved by the cuttenheads. It will also be evident to one skilled in the art that the bars or rails G G may be dispensed with, and that, although in the preferable construction of my invention, I use said bars or rails, the essential supports for shares the lower edges of the box shocks are the rails or supports G G. It will also be evident that the supports or rails G G'may be formed integral with the bearings for the cutter-heads, and that the supports G G are not necessarily of the same length as the bars or rails G G.

Movable lengthwisely upon each of the supports -G- is a pair of clamping jaws -lI--H-, which are formed with clamping faces 7L-7L* at their adjacent edges disposed in planes substantially parallel with the axes of the cutter-heads E-E-. The lower edges of these jaws *II-llare formed with shoulders t7zbearing upon the support or rail -G and with grooves 4t2-h2 for permitting the up and down movement of the movable rail -G- mounted upon said support. Secured to the outer face of each of the jaws -Iiare laterally-extending arms -H' 11' which cnupon the carriage Bn for "supporting the jaws in an upright position, and move lengthwisely of said arms as the supports -G-G- are adjusted toward and away from each other.

As clearly seen at Fic. 3 the rear clamping jaws ll-1^l are of substantially the saine height as the cutter-head -E-E in order that, when the carriage I3- is in its forward position, as shown at Fig. l, the inner faces of the cutter-head may be guarded, for preventing contact therewith of the operator or his clothing when handling the boards or shooks. The forward clamping jaws -H Ill-- are provided with lengthwisely adjustable inner face plates JIL-IIL; which are formed on their outer faces with ribs H3- 113- movable in upright grooves -Hl-HL- in the adjacent faces of said clamping jaws. These face plates are also formed with upright slots -H-HL- for receiving clamping bolts -Il-Ilsecured to the forward clamping jaws 1I-II- for clamping said face plates in position.

The arms -B-B- upon the carriage mli are formed upon heads or bars B2- $2-, and are adjustable toward and away from each other for simultaneously adjusting the front and rear clamping jaws II-H- so as to force their adjacent faces 7a-hagainst the outer faces of the interposed boards or shooks. 'lhis adjustment of the heads did-B2- is effected by moving the front head toward the rear head by means of a screw B3- arranged lengthwise of the carriage -B with its opposite ends supported in front and rear uprights B- 55- upon the front and rear extremities of said carriage. i

B is a hand-piece or wheel fixed upon a spindle -l7- journaled in the upper end of the front upright B4-, and" `8 is a gear fixed upon said spindle and meshing with the gear B9-e upon the feeding screw B3-3 whereby, when the hand-piece -PL- IOO IIO

opposite extremities of the carriage B-,

and, as clearly seen at Fig. 9, the nut -B' is formed with a lengthwise guideway or groove B12- 1n one face for registering with the central portion of said bar B11.

The front and rear heads f-B2-B2- are respectively fixed upon and'preferably formed integral with the nut B10- and the rear uprlght B5 upon the carriage -B-, and are each formed on their lower face with a lengthwise groove B13-in which are movable upturned ribs HL-HTM upon the adjacent clamping jaws -H-H.

As the supports `Gr--Gr--are moved toward and away from each other, as previously described, the opposite clamping jaws -H`H- movable upon said supports are also moved laterally upon the arms of the heads B2- B2-, as previously described, and, during said wisely withinthe grooves -BIB-BS-'in the heads -B2-B2.. Moreover, as the carriage -B moves to and fro within its guide -a--, the clamping j aws'H-H- are moved simultaneously with saidcarriage along the supports .-G- G, and thereby move the ends of the interposed boardsor shocks across the cutter-heads -E-E, since the ribs H7- formed upon said jaws interlock with the grooves B13- upon the heads BL-B2", as

`provide upon `one of the bearings -e in front of the co1l respondingcutter-head a gage -I-, Figs. 1, 2, 13, and 14, which consists of a movable plate -z'-, an adjuster and a clamp -1I2-. The plate -iis formed with an inner face -idisposed in a plane substantially parallel with the line of movement of the carriage -B-, and itsv outer end is v against the adjacent face ofgthe outerv end of movable in a guide e8 in the bearing -e-, and is formed with a'slot -t'4-. The adjuster -zis movable through an ear -eL- upon' the bearing 7-e andi its inner end bears i plate -i-, and serves to supportv said plate Y in its movement.

The adjuster --1l"- is held in its adjusted position by nuts -z'7- bearing against the opposite faces of the ear -ef-.

. The fastenerK--fis passed through the slot fitin the plate --i-, and one extremity is screw-threaded and engaged with a screw threaded socket e10- in thebearing -e-`-, and the other extremity is formed with a hand engaging portion or shoulder 738'- bearing against therupper face of the plate The supports for the lower edges of the boards or shocks, the clamping jaws for engaging the outer faces of the interposed boards, the means for feeding the jaws lengthwise of the supports, and the gage for regulating the depthof the grooves'to be formed in the end edgesof boards or shocks( are simple in construction, are easilyadjusted and operated, and are strong and durable in use.

As best seen at Figs. 1, 2, 18, and 19 the cutter-head shafts -eeare formed at their lower extremities with pulleys e11e11-, around which is passed a belt `J for rotating said cutter-heads, so that their adjacent'faces move in the same direction, as shown by arrows at Figs. 1S and 19. The belt ,-J- is driven in the direction also shown by arrows at Figs. 1S and 19 by front and rear driving pulleys -KK xed upon the shaft -k-, and is passed around idlers Figs. 15 and 16 having one end bearing against a downturned arm -Zc5- uponthe bearing -k3--, and the other movable in a supporting bar k6- interposed between the frame walls --A5-A5.l The belt J is passed beneath the idler-K.-, is twisted a quarter turn and extended to the right-hand,

IOO

.desired position byasuitable adjuster le4- so as to pass around the right-hand pulley -.e1l, is then twisted a quarter turn and extended to the left-hand so as to pass beneath the rear driver -K-, is then passed upwardly from the rear driver, twisted a quarter turn,

IIO

and extended to the right-hand so as to pass irrespective of the amount of separation ofthe cutter-heads -E-E-, since, as onecutter-head moves away from the drivingpulleys and the idlers, the other cutter-head` Amoves an equal distance toward said driving pulleys and idlers.

As previously stated the shaft-t-vis revolved bythe tight and loosepulleys -ClS-f C19-- in the direction shown dby arrow -3-- at Fig. 1, and the beltJ and idlers -K- KL- are then arranged as just described. It sometimes happens, however, that the power transmitting mechanism for revolving the pulleys-ClB-Cwis arranged to revolve the same in the opposite direction, and, instead of re-arranging said mechanism, I preferably slide the idlers -K-K2- lengthwise of the shafts -c-o2- into alignment with the rear driver K- instead of the front driver. The belt -.I, is then revolved in the direction shown by arrows at Figs. 25 and 26, and is then passed beneath the front driver -K-, is twisted a quarter turn, and extended to the right-hand so as to pass around the righ t-hand pulley e11-, is then twisted a quarter turn and extended to the left-hand so as to pass beneath and over the idler -K, is then extended to the right-hand and passed beneath and over the rear driver -K-, is then extended to the left hand, and passed beneath and over the idler -K2-, is then twisted a quarter turn and extended to the right-hand so as topass around the left-hand pulley cu-3 and is then twisted a quarter turn, extended to the left-hand and passed beneath the front driver -K. This is a particularly simple, practical, and effective construction of power transmitting mechanism foi-driving the adjacent faces of the cutter-heads in the same direction, and permitting of any desired adjustment thereof without varying the action of the power transmitting mechanism or necessitating its adjustment and is particularly applicable for use with my grooving machine. It will be understood, however, that said power transmitting mechanism forms no part ofk my present invention, and that it is here illustrated and brieiiy described merely for the purpose of more clearly and explicitly setting forth the operation of my grooving machine.

The operation of my invention will be readily perceived from the foregoing description and upon reference to thedrawings, and it will be particularly noted that the boards or shooks are readily adjusted in position upon their supports, are firmly clamped in their adjusted position, and that their ends are quick- 1y and practically provided with grooves, which are exactly true, and facilitate the ready assemblage of the box shooks, and that the parts of my invention are simple in construction, economically manufactured, readily assembled, easily and practically operated, are efficient in operation, and durable in use. It is evident, however, that considerable change may be madeinthe relative construction and arrangement of the parts of my groovin g machine, hence I do not herein limit my invention to the described construction and arrangement of its parts.

Having thus fully described my invention, what'I claim as new, and desire to secure by Letters Patent, is
