Claims.

This invention relates to apparatus for use with cutting and trimming saws employed in printing composing rooms, and has particular reference to an improved apparatus which is 5 selectively operable for directing the sawed lead and wood parts into separate containers and which includes means for Visually indicating whichof the containers is open for receiving the parts so 'as to avoid co-mingling of the lead and wood parts in the same container.

The invention comprehends an apparatus includinga chute having its open upp r end disposed under and in alignment with the saw so as to receive the partsseve'red by the saw as they drop therefrom; a pair'of containers at the bottom of the chute, manually operable means for opening and closing the chute toeither of 7 said containers and an indicating device operatively connected to and movable with said means for visually indicating which of said containers is open.

The invention further includes in an apparatus of the character described, a switch interposed in the circuitwith the driving motor of the saw, which switch is actuated by movement of the chute opening and closing means for breaking the motor circuit when the said meansis in open relation" with both of said containers and for closing the motor circuit when the said means is moved to fully closed position with either one of said containers.

With the foregoing and other objects in view, reference is now made to the accompanying drawing in which there is illustrated the preferred embodiments of the invention, while the appended claims cover variations and modifications thereof which fall within the scope of the invention; I

In the drawing:

Fig.1 is 'a perspective View of a'type slug saw in association with an apparatus embodying the invention.

Fig. 2 is a vertical longitudinal sectional view taken approximately on line 22 of Fig. 3.

Fig. 3 is a vertical transverse sectional view taken approximately on line 33 of Fig. 2.

Fig. 4 is an enlarged plan view of the switch ployed in printing composing rooms for cutting up lead slugs, metal'type or other metal material and wooden reglets, spacers, wood cuts and electrotypes, etc and which includes a driving motor H op'erativelyconnected to the saw by means of a belt l 2\which operates over pulleys i3 andM'carried by the shafts of the motor and saw respectively, a base l5 which supports the saw and provides a platform on which the material is fed thereto and a cabinet it on which the base if) is mounted and which houses the motor v v v For the purpose of providing means for collecting the severed lead and wood parts in sepa rate containers, the cabinet I6 is provided with a downwardly directed chute I? having an open upper end disposed under the saw and in align ment with the opening IS in the base i5 through which opening the severed parts drop as they leave theifsaw. The chute'i'i is preferably of rectangular shape in cross sectional configuration and is provided at the bottom thereof with a part of containers or drawers l9 and 251 which are open at the top and in communication with the chute. The said containers or drawers are arranged inlside by side relation at the bottom, of the cabinet IBand are slidable. in an opening 2! preferably in the front panel of the cabinet IQ so that the same may be withdrawn for emptying the sawed parts. The chute I1 is provided with a vertical partition 22 extending longitudinally of the containers l9 and 20 and from the upper inner'edges thereof to terminate in spaced relation with the upper open end of the chute and which subdivides the chute into laterally arranged ducts 23 and 24 which open at their lower ends into the containers IS and 20 respectively. 1

A deflector flap 25 is arranged within the chute above the partition 22 with its lower longitudinal edge disposed in longitudinal alignment. with the upper edge of the partition and secured to a rock shaft 26 pivoted in bearing openings 21 and 28 in the front and rear walls respectively of the chute. The rock shaft 26 extends forwardly through a bearing opening 29 in the front wall of the cabinet and is provided with a hand knob 30 on its free forward end for manually rocking the shaft so as to selectively dispose the deflector flap in downwardly sloping, inwardly directed covering relation with the upper ends of the ducts 23 and 24 respectively so that when the same is in covering relation with either one of the ducts the parts severed by the saw will be deflected into the open duct as the same drop thereupon.

An indicator 32 is arranged at the rear of the cabinet in the line of vision of an operator in front of the saw and is provided with indicia such as the word wood on one side thereof, and the word metal on the opposite side thereof, for visually indicating which of said containers l9 and 29 is in open relation with the chute. The indicator 32 is carried by the upper end of a rotary shaft 33 which is journaled in bearings 34 carried by the base and the rear wall of the cabinet respectively. The shaft 33 is operatively connected with the rear end of the rock shaft 25 by intermeshing miter gears 35 and 3B for imparting movement to the indicator 32 in timed relation with the movement of the deflector flap 25. In order to prevent operation of the saw when the deflector flap 25 is in any intermediate position where both of the ducts 23 and 24 are open and to permit of the operation of the saw only when one of the ducts is fully closed by the deflector flap 25, a circuit maker and breaker 3! is arranged in the motor circuit 38. The circuit maker and breaker 3'! includes a stationary contact member 39 having spaced contact points 40 and 4| and a movable contact arm 42 attached to the rotary shaft 33 and extending radially therefrom for movement therewith to respectively engage with the contact points 40 and 4| when the deflector flap 25 is in either of its two fully closed positions with relation to the ducts 23 and 24.

In the modified form of the invention illustrated in Figures 5 and 6 of the drawing, the deflector flap 45 is secured to a shaft 46 pivoted in bearing openings in the front and rear walls of the chute 41 adjacent the upper inner edges of the containers 48 and 49 and extends upward- 1y therefrom to a point where it terminates at the upper end of the chute. In this form, a manipulating rod 50 is connected with the deflector flap 45 adjacent its upper end and extends through aligned arcuate slots 5| and 52 in opposite walls of the chute 41 and through corresponding aligned slots 53 and 54 in opposite walls of the cabinet 55, the forward end of the rod 59 protruding from the cabinet and being provided with a manipulating knob 56. The rear end of the rod 50 protrudes from the cabinet 55 and is connected by a cable 51 to the periphery of the indicator shaft 58 so that as the deflector flap 45 is swung from one position to the other, the indicator shaft 58 is turned a half revolution to selectively display the indicia on the indicator 59 in accordance with the relative position of the deflector flap. In this form of the invention, the motor circuit 60 is opened and closed by means of a switch contact 6| on the manipulating rod 50 which selectively engages the fixed contacts 62 and 63 supported so as to be engaged by the contact 6| when the deflector' flap is in either of its two fully closed relations to the containers 48 and 49.
