Witnessea 4' at the right. Thus, there is not even the possible to avoid any catching of any'part of the person, This is much safer than where the moving part travels up anddown with the chance of catching the operator between the guard and the lower-part'ofthe press. Also, by having the gate moved-po'si 'tively by the shaft 15. that operates the punch, there isno chance of thexpunch op erating without operating the guard or gate.
: This is not the case with machines having- -,theguard operated some attachment to the treadle that operateslthe clutch because I frequently owing to some defect 1n the mechanism the punch may make two or more complete strokes for eachoperation I 'of the clutch, Where the guard is controlled by the means that. operates the clutch, the guard would not be inposition for the second or subsequentstrokes of the punch andthe operator is extremely liable to be caught. An advantage of ourfpresent invention lies its extreme simplicity and ease of attachment and adjustment to practically any punch press to which it' may be desired; to apply it, whether'the press be vertical or. inclined. Also, it will be-under-y stood that the device is susceptible to some slight modification inadapting it.;to 'dify ferent presses. Thus, for instance, wehave used the terms right. and left specifi cally in describing theexample herein,"and
, :other details of this eXamplehave been more or; less specifically described; but it willbe V understood that our invention is applicable 7 in other positions relative to the machine on which it'is used in order to'meet the various requirements encountered inapplying our, lnventlon to various kinds of mach1nes, not:
onl to ounchoresses but in an other" ower .V l l 1 driven machine wherea guard is-required.
Accordingly, we do notjw ish to be understood as beinglimited to the precise examples herein set forth, but what we claim as new and desire to secure by Letters Pat' ent is:
1 A..guard for a machine comprising a gate,,rolle rs on the top of said gate, rollers on the bottom of said gate, an; 1nverted channel extending transversely of said machine and receiving the rollers on sa1d top, a channel extending along under said ,1n-
verted channel and receiving the rollers on the'bottom of said gate, a double crank fulcrumed --on said I machine, an element con- Y necting one member of said crank to said 1 ,aoaeso gate, a crank arm fixed to a rotatable part of said machine, and'an element connecting the other member of said" crank'jto said 2. In'combinationwith a machine having a; rotatable part, a transverselyfmovable gate a support for said gate, a-crank arm attached to said rotatable part, sa1d crank arm being slotted where it is attached to said part, whereby its throw maybe adjusted, a crank fulcrumed on said support near said gatefan element .cennecting said crank'to sai'dagate, a pitman connecting said crank to said crank arm, and means adjust;
ably attaching said support to said machine. 3. A guard for a machine comprising a base plate, a channel fixed along said base plate with its openside upward, standards fixed on said base plate, an inverted channel fixed on said standards over the "aforesaid channel, a gate, rollers on'the bottom and on the top. of said gate, bearing 1n the re-. spectlve channels, a double crank fulcrumed on said base platenear one end thereof, a
connecting rod connectingsaid gate to one member of said crank, a crank arm attached to a rotatable part of said machine, a pitman connecting saidcrank arm to theother member of said crank, said base plate-havmg a slot, and fastening means extending through said slot into a part of. said ma- 7 chine, permitting said base plate and the parts carried thereby'to be adjusted. rela tively to ,said machine.
