B OARD KICKER FOB END-MATCHING MACHINES.

Application filed June 22,

My present inventionprovides an improved device which may be appropr ately. designated as a board kicker and which is adapted for use in connection with varlous different kinds of board or strip-forming or treating machines,;such, for example, as machines known as end matching machines for forming grooves or tongues in the ends of flooring and the like. For the purpose of illustration, my invention will be herein partioularly described in its application to a machine of the type disclosed and claimed in the application of Willis S. Sherman, Serial No. 168,820, filed May 12,1921, andentitled Flooring end machine, but it will, of course, be understood that the invention is not limited to-this particular application.

In the accompanying drawings, which illustrate the invention,-like characters in- :0 dicate like parts throughout the several VlGWS.

Referring to the drawings:

Fig. 1' is a diagrammatic view partly in side elevation and partly in vertical section, illustrating theinvention applied as above indicated;

Fig. 2 is a rear end elevation, to wit: a view looking at the parts shown in Fig. 1 from the right toward the left, some parts 50 being broken away;

' Fig. 3 is a fragmentary view showing certain parts found just at the left of the line marked 38 on Fig. 1; and

Fig. 4 is a fragmentary view partly in rear elevation and partly in vertical section, illustrating a modified form of the kicker.

Of theparts of the machine here illustrated and also illustrated in theSherman applicationabove identified, it is only desirable for the purposes of this case to particularly note the feed table 5, guide rails 6, framework 7, power driven crank shaft 8, rocker arm 9, and rake-acting feed bars 10. The rocker arm 9 is pivotedat 11 and the rakeacting feed bars 10 are pivotally connected thereto at 12, through a cross-head 13, the arrangement of which latter need not be here considered. The crank shaft 8 carries a crank ldpivotally equipped-with a block 15 when.

mounted to run over-suitable guiding and driving roller-s17. In the flooring end matchlng -mach1ne,"certa1n-of the elements of which have just been described, the fioor- 2 ally about'sixteen feet in length and would not'be within reach of the operator,'who should stand near the left-hand or delivery endo'f said belt, from which position he should be able to reach all of the boards or strips, whether long or short, and, hence, readily transfer the flooring boardsor strips to a second adjacent machine. It may be here further explained that inthe end grooving or matching machines, the flooring boards or strips'are first grooved or formed with tongues atoneend by one machine .and

are then delivered to a second machine, which latter or second machine puts on a tongue or groove. Hence, it is important that the boards or strips, whether longor short, should be delivered with their ends nearly even at the left-hand or delivery end of the feedbelt.

.My invention provides a so-called board kicker, which will now be described and which serves to perform the desired function above indicated.

This board kicker may take various different forms and may be operated in various different ways but should be timed so as to kick the boards endwise as they are delivered from the rails 6 01 other guiding devices. In the construct on lllustrated 1n Figs. 1, 2

I and 3. the kicker comprises a kicker arm 18 adjustably secured by nutsv 18 to a rock shaft 19 mounted in bearings 20 secured on the frame 7, and interposed adjustable collars 19 which permitlateral adjustment of the shaft 19. At its lower end, the arm 18, is provided with a kicker head 21 which,

' as shown, is. pivoted'thereto and adapted to be clamped in ditferent adjustments by a small nut-equipped bolt 22 or the like.

Just beyond the delivery ends of the guide rails 6 is a suitably fixed shelf 23 on which the right-hand ends of the fioor boards y, whether long or short, will be directly delivered and held in supported positions where they are adapted to be engaged by the kicker head 21 when the arm 18 is oscillated inward or toward the left in respect to Fig. 2. Extending toward the left from the shelf 23 and located slightly below the plane of the upper surface thereof is an inclined defiectingledge or board 24 supported at its right-hand end by a bracket 25 and adapted to be supported at its left-hand end by suitable means, not shown. This deflecting ledg'e 24 is preferably made about as long as the feed belt 16 and. extends parallel thereto and is preferably located at the front side of said belt, its inclination being in a direction transversely of the belt, so that the floor boards will slide off from the same onto the belt. To insure the proper delivery of the boards or strips onto the feed belt 16, the deflecting ledge 24 is shown as provided with a raisedlongitudinally oblique board-deflecting surface 26, which, however, is not a feature of my invention. 7

In machines of the general type disclosed and claimed in the Sherman application above identified, means is provided for holding theright-hand ends of the floor boards down upon the rails 6 while the boards are being fed-through the machine and for supporting the left-hand ends of long floor boards during such movements. When the floor boards are fed off from the rails 6, if they are of any considerable length, their left-hand ends will drop slightly onto the inclined ledge or shelf 24.

At its outer end, the rock shaft 19 is provided with an arm 27, to which the upper end of an operating link or connecting rod 28 is pivotally connected, preferably by means of a nut-equipped wrist pin 29 that is adjustable in a longitudinal slot 30 of said arm. At its lower end, the connecting rod 28 is connected by a universal pivot 31 to a projecting arm 32 carried by the rocker 9. The connecting rod 28 is preferably provided with a turnbuckle 33 for adjusting it longitudinally.

The numeral 34 indicates a board stop suitably supported and located atthe deliveryvend of the belt 16 in such position to stop the floor boards or strips substantially as shown in Fig. 3.

Operation.

The fioor boards or strips will be raked offfrom the rails 6 by movements of the rocker arm 9 and the rake-acting feed bars 10 toward theright in respect to Fig. 1, and through the connections described, the kicker head 21 is so set and timed for action that it will engage the right-hand end (in respect to Fig. 2) of the board or strip as or soon after it is delivered off from said rails and will project the same endwise toward the left in respect to Figs. 2 and 3. Under this kicking action, the advanced end of the floor board, if the board is of any considerable length, will be thrust against the deflecting surface 26, and by the latter and by the inclination of the ledge 24 will be directed downwardand onto the delivery belt 16. Some of the boards may not strike the defleeting surface 26 but will be kicked or projected onto the ledge 24 and will be delivered onto the belt 16 and so, in time, will be delivered to the stop 34. By the action of the belt, the floor boards or strips will be delivered against the fixed board stop 34, so that they will accumulate, substantially as shown in Fig. 3, where the operator, standing at the outer or left-hand end of the belt, may conveniently reachand quickly remove both long and short boards. of the pivotal connection between the arm 27 and the connecting rod 28 will vary the length of stroke that will be given to the kicker head. Longitudinal adjustments of the connecting rod 28 will serveto set the kicker head in its proper normal position in a direction toward and from the end of the floor board. By radial adjustments of the kicker arm 18 or by pivotal adjustmentof Adjustments the head 21 in respect to said arm, the 7 kicker head may be set at the proper elevaboards or strips.

In the modified construction illustrated in is F ig. 4, the kicker head 21 is formed as a raised projection of a slide 35 mounted to move on a fixed guide plate 36 secured to a projection 7 of the frame 7. In this arrangement, the slide 35 serves as a shelf to receive the outer ends of the fioor boards or strips. Otherwise, the operation of this kicker is substantially like that of the kicker shown in Figs. 1, 2 and 3.

From what has been said, it is obvious that the invention described is capable of very considerable modification, and as herein repeatedly indicated is not limited to use in connection with any particular kind of board or strip-feeding mechanism nor to use in connection with machines for making or treating any particular kind'of boards or strips. The term boards or strips is herein used in a broad and liberal sense.
