HOWARD W. LODER, OF NEW YORK, N. Y.
TREADLE MECHAIIISIE.
Specification. of Letters Patent.
Application filed May 5, 1908.
Patented March 30, 1909.
Serial No. 430,908.
To all whom it may concern:
Be it known that I, I'TOWARD W} LODER, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and improved Treadle Mechanism, of which the following is a full, clear, and exact description.
The object of the invention is to provide a new and improved treadle mechanism or use on sewing machines and the like, and arranged to permit convenient and quick adjustment of the treadle, to suit tall or short persons, with a view to enable the same to actuate the machine with the least physical exertion and with the greatest comfort.
' The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.
A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar'characters of refercn'c 'idicatc cor responding parts in both views.
Figure 1 is a cross section of the improvement; and Fig. 2 is a front elevation of the same.
A treadle A of the usual shape is provided at its sides near the middle thereof with trunnions B, B, journaled in the forward end of a swing frame 0, fulcrumed at its rear end at D on the frame Eof the sewing machine or other machine on which the treadle mechanism is used. The trunnions B B are pivotally connected by links F with hand levers G fulcrumed at their rear ends at H on the frame E, and the forward ends of said hand levers G are adapted to engage corresponding notches in the racks I attached to the frame E atthe front thereof.
The rear end of the treadle A is pivotally connected by a link J with a pitman lever K, fulcrumed at L on one of the hand levers G, and the forward end of the said pitinan' lever K is pivotally connected with a pitman N engaging a wrist pin 0 on the pulley or fly wheel P of the sewing machine or other machine on which the treadle mechanism is used. Now when the treadle A is actuated by the operator in the usual manner, it turns on the trunnions B, B supported by the swing frame (1 and the links 1 and the rocking mo tion given to the treadle A is transmitted by the link J to the pitman lever K, which in turn actuates the pitman N turning the pulley or fly wheel P. When it is desired to raise the treadle A to suit a person of shorter stature, then the hand levers G are disengaged from their notches in the racks I, then swung up ard and each engaged with a notch while up, as indicated, for instance, in dotted lines in Fig. 1, so that the links F are lifted and with it the trunnions B, B whereby a forward and upward swinging motion is given to the swing frame C, at the same time raising the treadle A the desired distance, as indicated in dotted lines in Fig. 1. Thus from the foregoing it will be seen that by simply adjusting the hand levers G, the treadle A can be readily raised or lowered, so as to bring the same in position for persons of different stature, to enable such persons to actuate the treadlo A with the least physi exertion and with the greatest comfort.
if desired, the link F, the lever G and the rack I at the left of Fig. 2 may be omitted as it is not absolutely necessary that the said parts be employed at both sides of the machine.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:
1. A treadle mechanism, comprising a readlc, a swing frame on which the said roadie is mounted to rock, an adjustable upporting device for raising 0r lowering the said swing frame and treadlc, and a powertransmitting device connecting the said trcadle with the part to be rotated, the said power-transmitting device being hung on the said adjustable si'lpporting device.
2. A treadlc mechanism, comprising a treadlc, a swing frame on which the said trcadle is fulcrumed, an adjustable hand levcr pivotally connected with the said swing frame, a pitnian, and a pitman lever fulcrumed on the said hand lever and connected at one end with the said pitman and at the other end with the said treadle.
3. A trcadle mechanism, comprising a treadle, a swing frame on which the said treadle is fulcrumed, an adjustable hand lever, a link connecting the said hand lever name to this specification in the presence of with the said swing frame a pitnian, a pittwo subscribing witnesses.
