This invention relates to improvements in mechanismf'for controlling the-operation of machines. of the type which are usually-operatedby an operator-standing-atthe machine and controlling 'the'operation ofthe machine by means of foot-operatedcontrolling levers.

786,190,.gra11ted .Marchp28, .1905 on ap'plil cation of Louis .A. Casgrain, for example, it has been necessary 'for the operator 'tofstand up for long periods WhiCh:CLllS8S fatigue to theoperator withthe result'that at the end of the day (or working period-) there ista fmarked decrease in the production of the operator andin the quality ofthe work produced. Y

H Oneof theo j therpr-esent invention isto provide a mechanism for-controllingthe operation of a machine the use of which will prevent or minimizefatigue tof'the; operator. I 1 One feature'of the inventioma'ccordingly, resides in a mechanism for controlling the operation ofa' machine having-afoottreadle secured to the lower portion cf the-base of the machine, a bracket secured'to the machine base,-a second foot treadlepivoted toisaid bracket and located above said first-mentioned foot treadle, Y and connections between the 'treadles including a lever actuated only byzthe upper'treadle whereby anoperatormay control the operation -"of the machine from a a plurality vof positions, said-treadles-being so arranged'that the use of one of the treadles is not interfered with by. thewther treadle. Preferably and as illustrated the. machine is provided with the vusual foot-operated'treadle treadles located above the usual .treadlesof the machine in such position that the 3-,

erator whenseated in 'front ofthe machine, for example, on a high stool, may use the auxiliary treadle machine. The illustrated treadle mechanism 'may be applied 'tomachines of the type disclosed in the above-mentioned Letters Patent, or,

to other machines wherein the operation of the machine is controlled through foot-opercontrolling the operation of the =fasteninginserting mechanism of the machine. .machine is also provided with the-usual footoperated treadle 1.41 which is connected to, the

A second foot operated treadle 18 is also I provided for lowering the] horn and; horn tip 20toallowfor thepresentation of work to the machine; For E1'*IDOIe;d8titll/d dQSCFlP? the above-mentioned Letters Patent; I p

a The mechanism for operating-'thefmachine while :the operator is inya sitting ;position will now-be described. aAtreadlc 221isplaced in such a position that the operator while .sit-

rest his foot on I the 'treadle .and; operate i-itfto chair is arranged relativelyfto the front of themaehineandheightwise inthemost conthe particular operator of the machine.

v vThe seat of .theillustrated chair is about of a vertical line through the center of the horn tip of the machine. These dimensions, however, will naturally depend both on the dimensions of the machine and the size of the 5 operator. The chair has a back rest 26 arranged in the most suitable position to support the back of the operator. The height of the chair may be varied in any suitable manner in accordance with the height of the operator. 1

The treadle 22 is pivoted at 28 to a bracket 30 which is fixed to one of two vertical parallel bars or arms 32, 32 connected together at their upper ends bya bolt or cross bar 34 and fixed at their lower ends to the base 10 at the rear ofthe column 12. V Stay bars 36,- 36 are fixed'at their lower ends to the base 10 by 'meansof a pin 37. which also forms a fulcrum for the treadle lever 14. The upper ends of the stay bars 36 are connected to the bars 82, 32 thus holding the bars 32 rigidly in'position. "A block 38'is adjustably fixed to the forward portion of the treadle 22. The heel of they operator rest-s against the block 38 and the position of the block maybe varied'in accordance with the requirements of the particular operator. As shown in Fig. 3, the for- I .ward end of the treadle 22 does not extend forwardly 1 of the base '12Qand accordingly does not interfere inany (way with the operationof the machine the treadle 14.

The rear end of the treadle 22 is pulled down about its pivot by a spring 40'connec ed at one end to an'arm 41 extending rear- Wardly from the treadle 22 and at the other end to one of the vertical bars 32. The movement of the treadle 22undcr the influence of the spring is limited by a stop screw 44 fixed in the bracket 30. A lever 46 is pivoted on the bolt 84 and one arm of this lever extends under but not quite in contact with the treadle 22; A plate 48 fixed on the treadle 22 is engaged by theforward end of the lever 46 when the treadle is depressed, the plate acting to prevent wear on the bottom surface of the treadle. The other end of the lever 46 is forked, as shown in dotted lines in Fig. 2, and engaged beneath a block 50 which is adjust'ab'ly fixed on the rod 16 by a set screw 51. A rest 52' for the'left foot of the operator is arranged at the leftsha nd side of the machine and this rest'is fixed bya, bracket 54 to one of'the stays 36 and by abracket 56 to the base 10' I: i "The treadle mechanism just described was developed particularly for use when'the machine isemployed forslugging looseheels, though'obviously it can beused'under other conditions. The machine, as is usual, stops tip 20. and the usual guard plate of themathe horn. I H 1 Having thus described my invention, what I claim as new and desire. to secure by-Letwith the/horn lowered sufliciently to'enable' the operator to insert a heel between the horn the operator can readily pick up a heel with.

foot to give him a small change in position.

The operatormay work alternately in a sitting or standing position and this change is readily made by merely moving the chair toward or away'f-rom the machine.
