FALL-ROPE CARRIER.

SPECIFICATION forming part of Letters Patent No. 723,816, dated March 31, 1903.

Application filed November 22, 1902. Serial No. 132,485- (No model.)

To all whom it may concern.-

Be it known that 1,.MASON BRADFIELD, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Fall-Rope Oarriers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to conveyers, and particularly to fall-rope carriers; and some of the objects of the invention are to provide a device of this character which will be simple in construction and positive and effective in operation.

Another object of the invention is to provide a fall-rope carrier which can be deflected laterally in either direction by the passage of the trolley and which is constructed to prevent unnecessary wear or injury to the lines or ropes passing thereover.

With these and other objects in view the invention consists, essentially, in the construction, combination, and arrangement of parts, substantially as more fully described in the following specification and as illustrated in the accompanying drawings, forming part of this application, in which- Figure 1 is an elevational view, partly broken away, illustrating the fall-rope carrier and the support therefor., Fig. 2 is a top planview, partly broken away, illustrating the device in the normal position of the parts. Fig. 3 is a similar view illustrating the device deflected in one direction. Fig. 4 illustrates the device deflected in the opposite direction. Figs. 5 and 6 are detail views of some of the parts of the device, and Figs. 7, 8, and 9 illustrate the device in different positions in connection with a trolley. I

Similar characters of reference designate corresponding p rts throughout the several views.

Referring to the drawings, and particularly to Figs. 1 to 6' thereof; the reference character 1 designates a post, only part of which is shown, and with which is connected a bracket or hanger 2 of any preferred construction, and upon the squared end of the bracket-2 is mounted a plate 3, having a squared opening 4 to receive the squared portion of the-hanger or bracket 2 to retain the plate in a fixed position, and the plate is preferably provided with a pin or stud 5, substantially as shown.

Mounted upon the cylindrical portion of the hanger 2 and below the plate 3 are jaws or members 6, preferably constructed with an enlarged circular end '7, having an opening 8 therein to receive the hanger and preferably cut away on one face, as at 9, Fig. 1, to receive the similar end of the other jaw or member, and each of the jaws or members is desirably recessed, as at 10, to receive the stoppin 5, before mentioned, and the jaws may be.

notched or recessed intermediately thereof to receive the pin or stud 11, extending from a lower plate 12, movably secured upon the round portion of the bracket or hanger 2, and formed on or connected with the plate 12 is an arm 13, carrying a revolulole sleeve let and having the end thereof deflected laterally, as at 15, and carrying a sleeve 16, said sleeves being designed to prevent injury or wear upon the lines or ropes passing thereover, as will be readily understood by those skilled in the art to which this invention appertains.

The operation of this invention will be readily understood from the foregoing description when taken in connection with the accompanying drawings and the following eX- planation thereof.

Adverting-now particularly to Figs. 7, 8,

and 9 of the drawings, there is illustrated a trolley 17, havinga deflecting-band 18, adapted'to contact with the sleeve 16 uponthe deflected ends 15 of the carrier and to defiect the latter, as shown in said figures. The sleeve 16 also tends to reduce the friction occasioned by the contact of the deflecting-band 18 with the end of the fall-rope carrier, and the coiled or other spring 19, connected with the jaws 6, tends to return the carrier/to its normal position across the line of travel of the trolley. (See Fig. 9 of the drawings.) By means of this construction a fall-rope carrier is provided which is extremely simple in construction, embodies very few parts, and is most positive and efiective in operation, as can be readily appreciated.

It is not desired to confine this invention to the specific construction, combination, and arrangement of parts herein shown and described, and the right is reserved to make all such changes in and modifications of the same as come within the spirit and scope of the invention.

I claim 1. The combination with a trolley and means for supporting and moving the same of a device constructed to normally carry said moving means and provided with a wheel or roller in the extremity thereof to contact with the side of the trolley while being. temporarily deflected by the passage thereof.

2. The combination withasupporting-cable and a trolley thereon of an arm carrying a projection, spring-actuated jaws in contact with said projection and a device in engagement with said jaws constructed to be forced aside by the passage of said trolleyand to be returned to normal position by one of said jaws.

3. The combination with a cable and a trolley thereon of an arm carrying a projection jaws held against said projection by a connecting-spring and a device in engagement with said jaws to be returned to normal position thereby.

The combination with a cable and a trolley thereon of an arm carrying a projection, spring-actuated jaws held against said projection, an oscillating arm having a pin normally engaging said jaws, whereby when the free end of said arm is deflected by the passage of the trolley the pin forces one of said jaws away from said projection against the action of said spring.

5. The combination with a cable and a trolley thereon of a fixed arm having a projection, spring-actuated jaws connected therewith and an oscillating arm in engagement with said jaws constructed to be returned thereby to normal position when deflected.

6. The combination of a cable and a trolley thereon of a fixed arm having aprojection, jaws pivoted to said arm, a spring connecting said jaws and drawing the same against said projection and an oscillating arm having a pin extending between said jaws so that one .or other thereof returns said oscillating arm to-normal position after the deflection thereof.

7. The combination witha cable and a trolley thereon ot' a fixed arm having a projection, jaws, a spring forcing said jaws against said projection, an arm engaging said jaws and an antifriction device carried by said latter arm to engage said trolley during the passage of the latter.

8. The combination with a cable and a trolley thereon having a deflecting band or belt, a fixed arm having a projection, jaws, a springforcing said jaws against said projection, an arm engaging said jaws and an anti friction device carried by said arm to engage said band or belt during the passage of the trolley.

9. The combination with a cable and an in' dependent bracket supporting said cable and having a hanger of a trolley on said cable, a fixed arm connected with said hanger having a projection, jaws, a spring forcing the jaws against said projection and an arm engaging said jaws and constructed to be forced laterally by the passage of the trolley.

10. The combination with a cable, an independent bracket supporting said cable and having a hanger and a trolley on the cable of a fixed arm mounted on said hanger having a projection, spring-actuated jaws pivoted upon said hanger and an arm engaging said jaws constructed to be deflected by the passage of the trolley and to be returned by said jaws.

11. A fall-rope carrier provided with an arm carrying a projection, spring-actuated jaws normally in contact with said projection and a device in engagement with said jaws constructed to be forced aside and to be re turned to normally carrying position by one or other of said jaws.

12. A fall-rope carrier provided with an arm carrying a projection, spring-actuated jaws held against said projection, an oscillating arm having a pin normally engaging said jaws whereby when said oscillating arm is deflected the pin forces one of said jaws away from said projection against the action of said spring and a sleeve on said oscillating arm.

13. A fall-rope carrier provided with a fixed arm carrying a depending pin, springretracted jaws beneath said arm and normally in engagement with said pin and an oscillating arm carrying a pin engaging said jaws so that the latter returns said oscillating arm to normal position after deflection.

14. A fall-rope carrier provided with a fixed arm carrying a depending pin, springretracted jaws pivotally mounted beneath said arm and normally engaging said pin, an oscillating arm carrying a pin engaging said jaws so that the latter retain said oscillating arm in normal position and antifrictionsleeves upon said oscillating arm.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, at Los Angeles, in the county of Los Angeles and State of California, this 10th day of November, 1902.
