UNITED STATES PATENT OFFICE.
CHARLES JAMES HIBBERD, OF ANNAPOLIS, MARYLAND.
BLOCK AND vTACKLE.
SPECIFICATION forming part of Letters Patent No. 379,113, dated March 6, 1888.'
Application filed November 25, 1887. Serial No. 256.144. (No model.)
To all whom, it may concern.-
Be it known that I, CHARLES JAMES HIB- BERD, a citizen of the United States, residing at Annapolis, in the county of Anne Arundel and State of Maryland, have invented certain new and useful Improvements in Block and Tackle; 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.
Referring to the accompanying drawings,
' Figure 1 represents the general arrangement of a block and tackle embodying my invention. Fig. 2 is an enlarged detailed view of my improved pulley block with one of the faceplates removed. Fig. 3 is a detail of the pivoted pulley-carrying lever.
construct-ion and indicate the manner inwhich the same is carried out.
In the said drawings, A represents the usual pulley-block, to which one end of the rope or cable B is secured in any appropriate manner, said rope or cable passing therefrom to and under a pulley journaled in a block, B, as-
shown in Fig. 1.
In the top of the block A, upon the bar A, is suitably secured the usual swivel,G, and be tween the face-plates a of the block A, and in the upper portion and to one side of the vertical center of the same, is secured a recessed block, G, having downwardly-extending lugs b, the purpose of which will be hereinafter fully disclosed.
Between the face-plates are pivotally secured the arms 0 of a bifurcated lever, D, said arms being contracted at one end and uniting to form the long arm of the lever, and also to form a guide or opening through which the free end of the rope or cable is passed.
Within the lever D, and at points between the arms and upon each side of the pivotal center of the lever, pulleys E E are loosely mounted, the rope or cable, after extending from the lower pulleyblock, B, being passed over said pulleys E E, andhas its free end directed to and passed through the guide or opening in the lever between the pulley E and the end of said lever.
In operating my device, as when raising a heavy weight, the strain or power is brought to bear upon the pulley E, to cause the extended portion of the lever to be depressed and the opposite portion carrying the pulley E to be elevated. When in this position, which is the normal position in elevating the weight, the rope or cable is permitted to run freely through the block; but the instant the pull or power is removed from the drawing or free end of the cable the weight acting upon the pulley E causes the pivoted lever tobe tilted in an opposite direction, whereby the rope or cable is tightly clamped between the pulley E and the downwardly-extendinglugs or arms I) of the block G, as seen in dotted lines in Fig. 2. In this latter position the rope in the groove of the pulley E will be forced into the recess in the block G, and also tightly pinched at two points against the lower edges of the arms I). The said rope cannot possibly slip, for the greater the weight suspended the more tightly will the cable be gripped between the pulley and block.
If it be desired to lower a heavy article, the cable may be caused to pay. out slowly and with absolute safety by simply drawing upon the cord or connection 6, attached to the long arm of the lever D, until the pressure on the cable is released sufficiently to permit a regular and safe paying out of said cable and the consequent lowering of the article or weight.
By reason of the above construction I am enabled to provide a simple and effective means for elevating heavy articles, whereby, should the cable slip, the descent of the article would be instantly checked; or, if it be desired to suspend said article, the same may be effected automatically and with perfect safety by releasing the power or pull upon the cable.
Having thus described my invention, what block having two downwardly-extending arms I claim as new, and desire to secure by Letters adapted to pinch the cable at different points, Patent, iswhereby said cable may be securely held, as
An improved block and tackle consisting herein described. r5 5 of the pulleyblecks A and B, the cable B, In testimony whereof I affix my signature in the bifurcated lever D, pivoted within the presence of two witnesses.
