' RELISI-IING-MACHINE.

Specification of Letters Patent.

Ldfithtifid.

' Application filed a 1-11 machine in which the work is automatically carried to the cutters and effectively held while being acted upon by the cutters.

Second, to provide an improved relishing machine which is quickly adjustable to different classes of work.

Third, to provide an improved relishing machine in which the adjustment may be easily accomplished by persons other than skilled workmen.

Fourth, to provide an improved machine of the class described which is of large capacity.

Fifth, to provide in a machine of the class described an improved conveyor.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a front elevation of a structure embodying the features of my invention.

Fig. H is an end elevation looking from the right of Fig. I.

Fig. HT is a detail rear perspective showing details of the conveyor and the work holdin means.

Fig lV is a detail front perspective show- .ing further details of the conveyer and workholding means and guides.

Fig. V is a plan view of the yielding work guide or end thrust member removed from its supports. 1

In the drawing similar reference characters refer to similar parts'throughout the several views.

Referring to the drawing, the main frame of the structure illustrated comprises end members consisting of uprights 1 and cross lowered.

pieces 2. These end members are connected by horizontal members 8. The frame is also rovided with intermediate upright members a provided with crosspiecesand supporting the feed conveyor and other parts. At each end of the frame are spaced uprights 5 secured to the crosspieces 2 and projecting above the same. The uprights 5 have cross members 6 at their upper ends.

Mounted between these uprights 5 is a horizontally disposed head bar 7. his head bar is vertically adjustable, beingsecured in its vertically adjusted positions by means or the clamping bolts 8 arranged through the uprights below the'head bar to clamp the uprights thereon. The head bar is vertically adjusted by means of the screws 9 arranged through the crosspieces 6 and having threaded engagement with the head bar.

On the upper ends of these screws are sprocket wheels 10 connected by the sprocket chain 11, one of the screws being provided.

with an adjusting crank 1. By this arrangement both ends of the head bar are simultaneously ad usted or raised and.

The cutters 13, which are shown conventionally, are carried byhead members 14 and 15 mounted upon the under side of the head bar 7. The head member 15 is adjustably mounted to provide for the axial adjustment of its cutter. Clamping bolts 16 are provided for securing the head member 15 in its adjusted position and the screw 17 having a hand wheel 18 is provided for the adjustment of the head member.

The head member 15 has a pointer. 10, while the head bar has a scale 20 with which the pointer coacts. The head. bar has a pointer 21 and onset the uprights 5 has a scale 22 with which the pointer coacts.

The driving shaft 23is mounted on the lower part of the frame, the shaft being provided with a driving pulley 24 and with pulleys 25 and 26. The cutter shafts 27 have pulleys 28 connected to the pulleys 25 and 26 on the driving shaft by means of the belts 29. The belt tightener pulleys 30 are tensioned by means of the weights 31, so that the raising and lowering of thehead bar 7 does not affect the driving connections or does not require any readjustment of the driving connections.

The feed conveyor comprises sprockets 32 and 33, the shaft 34 of the sprocket 33 being extended in ne a f the frame and pit Patented Tree. 26 1921..

vided with a sprocket wheel 35 by which it is connected to the driving shaft 3301 other source of power, not shown.

The upper reaches of the sprocket chains 36 travel upon the ways or supports 37 disposed between the sprocket wheels .The sprocket chains have work carriers consisting of the rigid flights 38 carried by spaced 7 arms.

As the flights and clamping members pass over the front sprockets onto the upper reaches of the conveyer they swing towarr each other to clamp the piece of work, as l0, firmly gripping'the same, so that it is carried along by the conveyer.

To hold the work firmly on the conveyor I provide rearwardly inclinedpresser bars 41 mounted at their forward ends on supporting arms 12 by means of the springs 43. Blade springs 44- are mounted on these arms 42 to. press downwardly upon the .rear ends of the presser bars. Screws 45 through the arms engage the springs regulating the pres sure of the bars. These arms are mounted upon the cutter head bar 7 To further assist in holding chattering thereof 1 mount a spring 46 cen-- trally between thepresser bars, the spring being positioned so that it engages the work about the time the cutters begin to act thereon and presses and holds the same firmly while being acted upon by the cutters. The

necessary pressure could be provided by the presser bars 4-1 butby providing this additional work holder the necessary pressure at the desired point is provided without the necessity for undue friction during the vmajor part of the time while the work is .matically or the work may be fed thereto by hand.

I have not shown my improvements in relation. to any other machine as it will be readily understood that they may be associated with other machinery as desired.

My improved machine is of large capacity the work while acted upon by the cutter preventing and is readily adjusted to various classes of work as desired and is entirely automatic. 1 have illustrated and described my improvements in one embodiment which I have found very satisfactory. Various parts are showniconventionally. I have not attempted to illustrate or describe other modifications and adaptations which I contemplate as l believe the disclosure made will enable those skilled in. the art to which my invention relates to embody or adapt the same as may be desired.
