To all'w hom it Mag/hmtcern:

Be it known that I, JOH Cnoss FIELD, a II citizen of the United States, and a resident of Lutcher, in the county of St. J ames and State of Louisiana, have invented certain 7 new and useful Improvements in Safety Split Set Collars, of which the following is a specification. I L i p This inventionrelates to improvements in set collars, andflmore particularly to a split afford safety to persons so as to prevent ing the danger. of wrappingor winding on its face or protruding screws orbolts as clothing thereon and causing injury, due to i the fact that the device has no open spaces .in the ordinary set collars.

-A further {object of the invention. is to provide a safety split set collar which may bequiclrly installed without removal of the i shaft, being adapted-to be installed or re-' moved. in view of its simplicity, in a minimum of time, as well as requiring a space for installation of its own width only and affording an absolutely smooth exposed' surface. I

A stillfurther object of the invention 1 is to provide a novel form'of joint between the projecting cilitating. the application of the set collar to sections of the split collar which obviates the necessityfor employing bolts and adapts the-safety covering to be applied without parts while-atthe same time fa a shaft to which the same is secured by the ordinary set screw, while the coverlng or safetyshiel'dcan be applied to solid or sin leiece collars tional view a device which can cluced and-which is bothst-rong and---durable,- l and not. likely to get out of order.

with absolute safety. Among others, it is also an object to provide be very economically pro- Other and further objects of my invention will-become readily apparent to those skilled in the art from a consideration of the following description, when taken in conjunction with the accompanying drawings, wherein! i Flgure 11s a perspective view of my improved safety split set collar, s Fig. 2 is across section thereof, and Fig. 3 is a fragmentary transverse secshowing the covering or shield. As illustrated, the improved set collar comprises sections 10 and 11 ofsemi-circular form, adapted to fit a shaft or the like, for the purpose of preventing side play or latpreferably of sheet .ing in the form designed to receive i 27 of the covering or shleld sections 20 SET COLLAR.
