JAMES HAWORTH, OF FRANKFORD, PENNSYLVANIA.

LOOlVL Specificaton of Letters Patent No. 5,021, ated March 20, 1847.

To all whom it may concem: p

Be it known that I, JAMEs HAWORTH, of Frankford, in the county of Philadelphia. and State of Pennsylvania, have invent-ed a new and useful Improvement in Looms, which is described as follows, reference being had to the annexed drawing of the same, making part of this specification..

Figure 1 is a plan or top view ofVV the frame and lathe.

In the construction of a common loom wherein a spring is used to force the swelllever against the shuttle ,considerable inconvenience is experienced arising from the friction of the shuttle in leaving the box.

against the swell lever pressed against it by the usual spring.

My improvement is designed to remove said fricton of the shuttle against the swell-lever and thereby to reduce the power required to operate the loom.

Besides the aforesaid object I also by my improvement effect another important object, name1y running the loom backward or in a contrary direction without the use of' the shuttle-when the loomis not performing the operation of weaving. .v

These two objects I effect in the following described manner I secure to the stop rod of the loom an additional finger A which is to be connected loosely With the arm B of the lathe by' means of a pin C inserted into the arm; or by bending thev finger A so as to lie upon the arm B; or

-lever H.

otherwise connected by which connection the stop-rod D. is vibrated during the operation of the loom in weaving, said vibration of the 'stop-rod having the effect of relieving the pressure of the finger E of the said stop rod against the swell lever F which bears against the shutt1e, thus relieving the shuttle. When the loom is not performing the operationof weaving but is running in a contrary direct-ion then the said ,addit-ional finger A vibrates the stop rod D causing the stop finger G to clear the stop This last named effect enables the weav'er to run the loom backwardv for any required purpose Without the necessity of holding back the swell lever by his hand or otherwise.

VhatIV claim as my invention anddesire to secure by Letters Patent is- The mode of relieving the pressure of the f* swell lever F against the shuttle Whilst the shuttle is leaving the bo-X also the mode of causing the loom to run back- -Ward without the use of the shuttle by means of the before described combination,
