Description
ABRAHAM W. HARRIS, or PROVIDENCE, RHODE ISLAND.
.Letters Patent No. 110,034, dated December 13, 1870.
|MPRovEwnaN-r 'INDEvlcEs Fon DRIVING SEWING-MACHINES.'
. The Schedule referred to in these Letters Patent yand. making part of the same.
`To all whomy z'tjmay conce'vrn:
Be it known that I, ABRAHAM W.' HARRIS, of the c'rty and county of Providence, in the State of Rhode Island', have invented a new and improved Device for Driving Sewing-Machines; and I do hereby declare that the following specication, taken' in connection with the drawing making a part ofthe saine,is a full, clear, and exact description thereof.
Figure 1 is a view of: the frame of a sewing-machine..
Figure 2 is a viewof the pulley E as applied to the machine. Y
Figure 3 is a view of the pulley E, with the plate K removed, showing the' same during back motion.
Figure 4 shows the pulley 'E during' its forward motion.
Figure 5 is a vertical section of the pulley. The object of my inventionv is-to prevent thebackward'm'otionrof the crank and-shaft, which often accompanies the starting of the machine, from communicating motion to the needle, and consists in thedevice for such purpose, hereinafter described.
It is well understood by those familiar with the use of sewing-machines that; when s tarted, they are as 'liable to be propelled irL one direction .as the other.
-The backward motion thus often attained results in structed with an outer rim, E', within which is a driver,
J, vhaving one or more rubber pawls N, which move upon an 'inclinedplane and operate upon the inside ofthe rim E. y
The driver J is attached to theshaft by a set-screw, while the outer rim or band-wheel E is left free upon the shaft.-
' The operation of my invention is as follows:
1f the machine be started in the wrong direction, the pawls N will recede upon their respective planes from the point of contact 4with thefrim E', as shown in g. 3, but the driver J' will continue to move the shaft A, revolving in the hub of the rim or band-wheel E', which remains stationary.
hen, however, the crank has been moved far enough to reversethe motion, the pawls N are immediately moved forward and upward upon their planes,
and nip the rim E', as sliown in fig. 4, and start tl'e machine nth'e right direction.
This device is equally capable of adaptation to sewingmachines not having a shaft extending acrossthe frame as well as to other machineswhere light work is required.
I do not conne myself to any particular construe.- tion' of pawl, as many',variations in construction may be'made, all, however, embodying the same principle.
WhatI claim as my invention, and desire t-o secure by Letters Patent, is
,1. A pawl, in combination with a loose band-wheel, E, and the crank-shaft A and treadle, the whole arranged and operating in the manlief substantially as described.
2. The combination of the elastic rolls N with the band E and the driver J.
ABRAHAM W. HARRIS.
