HANDHOLD-FORMING MACHINE Specification of Letters Patent.

latented June 11, 1907.

Be it known that we, ANDREW JACKSON CoLvIN, CLAUDE GATOH HOCKETT, and JOHN WILLIAM FITZPATRICK, citizens of the United States, and residents of Grants Pass, in the county of Josephine and State of Oregon, have invented a new and Improved Handheld-Forming Machine, Oflwhich the following is a full, clear, and exactdescrip- The invention relates to wood working machinery, and its object is to provide -a new and improved hand hold forming machine Inore especially designed for cutting hand holds in blank boards employed for forming boxes and the like.

The invention consists of novel features andv parts and combinations of' the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embo'diment'of the invention is responding parts in all the views.

Figure 1 is a plan view of the improvement, parts of the hopper containing the blanks be- Ing shown in section; Fig. 2 is a longitudinal sectional side elevation of the same on the line 2 2 of Fig. 1; Fig. 3 is a cross section o'f the same on the line 3 3 of Fig. 1,. and Fig. 4 is a cross section of part of the feed mechanism for the blanks, the section being on the line 4-4 of Fig. 1.

On a suitably constructed framework A is mounted a table B supporting a hopper C for containing a pileof blanks D, the lowermostof which is moved from under the pile one at along guideways E over the table B to and between dado or cuttei` heads G, G', for the latter to cut hand holds into opposite faces of ward cut in two sections so as to provide a hand hold for each blank section. The cutter heads G and G have their shafts G2 and G3 journaled insuitable bearings carried on crossfheads l-I and H mounted to-slide to ward andfrom each other in vertical guideways H2 attached to the framework A, as` plainly illustrated in the drawings. The cross heads H and H are reciprocated simultaneously from a main driving shaft I extendl vthe cutter heads G and G simultaneously toward and from each otlier In order to regulate the depth the cutter heads G and G cut into the opposi te faces of'the blank' D the eccentric rods J?, J3 are provided with turn buckles J, J5 to lengthen or shorten the said eccentric rods and consequently to move the cross heads H and H correspondingly and likewise the cutter heads G and G for the latter to cut to a greater or less depth into the blank D. The feed block F operates in unison with ythe reciprocating motiongiven to the cutter heads G and G and for this purn ose the feed block F is mounted to slide engthwise in suitable guidewa'ys F arranged on the main frame A, and the said feed block F is pivotally connected by a pitman F2 with a crank arm Fil secured on the main shaft I,

so' that when the latter is rotated a reciprocating motion in a lengthwise direction is given to the feed block F, and when the latter moves forward in the. direction of the arrow -a then it moves thelowermost blank D out when the feed block F is on the return stroke the cutter heads G and G move toward each other and cut into opposite faces of the blank D'extending Abetween the cutter heads G and G at the time. In order to regulate the stroke of the feed block F according to the width of the blanks D treated at the time, the connection between the pitman'fF2 and the crank IOOI IOS

with the latter.

arm F3 is adjustable by a wrist pin F adjustable within an elongated slot 4F5 formed in the crank arm F3.

In order to rotate the -cutter heads. G', G from the main shaft I the following arrangement is madey'On the shafts G2, GfV are secured pulleys K and K connectedby-belts K2, K3 with pulleys K4., K5 secured in a countershaft K journaled in suitable bearings on the rear end of themain fra-me A. On the conntershaftK is. secured a pulley L connected by a belt L with a pulley L2 attached to the main shaft I, so that when the latter is rotated'a rotary motion'isgiven to the coun- V tershaft K, which'by the pulleys K4, K5, the

belts K2, K3 and the pulleys K, K. imparts a rotary motion to the shafts G2, G? and consequently to the cutter heads G, G.. The belt K3 is preferably crossed to rotate the cutter head G `in the opposite direction to the cutter head G. The blank D acted on by lthe cutter heads G, G at the time is held against outward movement by spring catches N secured to the guideways E, it being understood thatthe spring catches N automatically release the finished blank when the feed block F forces the blanks 'Dforw.a'rd in the guideways. In order to prevent rearward movement of the blank acted on bythe cutter heads G, G at the time, dogs O areused for the purpose, the dogs being hung on the guideways E and inclined forward, the ser# rated bottom edges of the dogs 0 engaging the top of the blank immediately in the rear of the blank acted on by the cutter heads, see

Fig. 2. versely adjustable on the to accommodateblanks D ifferent width, and for this purpose each'guideway is pro- .The guideways E are held transvided with slotted lugs E engaged by bolts The feed block F' E2 held on the-table B. extends up througha slot B formed length'- wise in the table B approximately midway between the guideways E. u

The hopper C"s preferably made ofra number of posts C lengthwise adjustably secured bv set screws C2 onv the guideways E to move A cross board C3 is held vertically adjustable on the front posts C of the hopper C by the usel of bolts C, 'and this board C3 extends with its lower edge close tothe top of the lowermost blank D, to prevent .more than the lowermost blank D from being pushed out of the hopper C at a time bythe feed block F. t

The operation is as follows 'When the several parts are in the position illustrated in the drawings and the main shaft I is rotated, then the cutter heads G, G cut into the top and bottom faces vof the blank D in o'stion between the cutter heads, G, G"at t etime.

As soon as the hand holds have been cut to the desired depth the cutter heads G, G move vertically away from the blank provided'with the hand holds, and at this time top of the table B o d stare? the feed. block F moves forward in the direc? tion of the arrow a", and pushes the lower- Inost blank D out .from under the pile of blanks D and forward in the guideways E, lso that the blanks D in front `of this lowermost blank D are moved forward, and the outer most finished blank is moved out' from.b e'

tween' the cutter heads G', G Vand another blank D is moved between the` Said'cutter heads, and its movement is limited by the .spring catches N. During the return stroke vtion a blank'is provided with two hand holds,

and when. the blanki's subsequently'divided into two box sections, each box section has a hand hold. By having two cutter heads G, G cutting simultaneously into the blank at opposite faces and opposite each other no further holding down'devices for the blank are required.

Having thus described our invention, we

claim as new and desire to secure by Letters -the blank when between the cutters, and

means forl imparting movement in .unisonl to the said feed mechanism and the said cutter heads for the latter to cut the blank vat lthe time the feed mechanism is on thev return stroke and to moveout of'engagement with the blank at the time the feed mechanism moves another blank forward.
