CABLE-BELEASE FOR ELEVATORS.
T 0 all whom it may concern,
Be it known that I, SnLnnN H. Down, a citizen of the United States, residing at Olyphant, in the count-y of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Cable- Release for Elevators; 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 cable release for elevators, more especially for elevators or lifts employed in mines, and has for an obj ect to provide means for releasing the cable from the elevator or lift when the top of the shaft has been reached without breaking any of the parts, the means for preventing the drop of the elevator car forming the subject matter of a copending application.
A further object of the invention is to provide a cable release which releases the cable upon contact with the sheave to permit the cable to pass over the sheave without breakage or damage.
A further object of the invention is to provide means for releasing the cable with out regard to the position of the parts when contacting with the sheave.
lVith these and other objects in view the invention comprises certain novel constructions, combinations and arrangement of parts as will be hereinafter more fully described and claimed.
In the drawings: Figure 1 is a vertical sectional view through the improved cable release. Fig. 2 is a view partly in side elevation and partly with the housing broken away. Fig. 3 is a view with the housing broken away seen from a point at right angles to that of Fig. 2. Fig. elis a top plan view of the device.
Like characters of reference designate corresponding parts throughout the several views.
The improved cable release which forms the subject matter of this application comprises a tubular member or pipe 10 extending downwardly and connected in any approved manner with an elevator car or lift, here shown as broken, the connection with the elevator car being shown in a copending application, Serial No. 719,124, filed on even date herewith.
About the pipe 10 a housing 11 is slidably mounted presenting a top 12 positioned to Specification of Letters Patent.
Application filed September 7, 1912.
Patented Sept. 23,1913.
Serial No. 719,123.
engage with the sheave over which the cable 13 passes in operation. The mounting of the cable 1? and the connection of the ole vator car with the structure disclosed in this application forms no part of this invention but is fully disclosed in the aforesaid copending application. The tubular member 10 is 'irovided with cars 14, to which are pivoted levers 15, the levers having engaging extremities or detents 16 which are inserted through openings 17 fornled in the tubular member 10 and in position to engage against an annular shoulder 18 formed upon the needle 19 which engages the cable 13. Needle 19 is provided with a pointed extremity 520 which permits of its being inserted into the upper end of the tubular member 10 and between the detents 16, such detents being held yicldingly in engagement by springs 21. The housing is also provided with cars 22 in which are pivotally mounted links or bails 23 so n'oportioncd that when the housing 11 is depressed the levers 15 will also be depressed to draw outwardly the detents 16 to the position shown in dotted lines in Fig. 1.
It will be apparent, therefore, that when the device of which this disclosure forms a part is drawn upwardly into engagement with the sheave over which the cable 13 moves the head 12 will come into engagement with such sheave and force the lovers 15 downwardly to dotted position thereby releasing the needle from engagement with the detents 1(3 and permitting the cable to pass freely over the sheave released from the releasing device.
I claim:
'1. In a cable releasing apparatus, a tubular member, spring pressed detents extending into the tubular member in position to engage a cable extremity, a housing surrounding the tubular member, and links connecting the housing with the detents.
2. In a cable releasing mechanism, a tubular member, detents inserted through the tubular member and positioned to engage a cable extremity within the tubular member, a housing surroumling the tubular member and provided with an annular head embracing said member, and links extending from the head to the detents adapted to release the detents when the head depressed.
3. In a cable releasing mechanism, a tubular member, detents inserted in the tubular member and adapted to engage a cable extremity, a member entirely surrounding the tubular member, and means connecting such surrounding member with and to actuate the detents.
4-. Ina cable releasing mechanism, a tubular member, a needle proportioned to be inserted in the tubular member, detents pivoted upon the exterior of the tubular member and extending through slits in said member into engagement with the needle, a disk surrounding the tubular member at the end receiving the cable, levers earned by the 'detents, and links connecting the disk With the levers.
In testimony whereof I afiix my signature in presence of tWo Witnesses.
