IMPROVEMENT4 IN HAWSBR-GLAMPS.

"dlgs .stimule nfctreh te in this rtttts @sont :un making-pnt ni its smite.

TO ALL WHOM IT MAY CONCERN:

Be it known thatwe, HENRY A. ELLIS and C. FRED. GLAnnrNo, of Norwich, in' the county of New London, and, State of Connecticut, have invented a new and improved Hanser-Clamp," and we do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawings,

making a part of this specification. 4

The object 'of our invention is to furnish a very convenient and substantial fastening for all kinds of hawsers, ropes, or lines, whereby the slack" or loose portion between the two ends can be made taut or drawn up, and held atany. desired position, without the necessity of loopsor knots.

Figure l is a front elevation, showing a portion of a rope clamped.

Figure 2 is a sectional view at right angles to iig. 1, and with the clamps open.

Figure 3 is a partial plan of the rear of tig. 1.

Figure 4 represents a portion of the double-eccentric lever, with a flange for withdrawing the moving ciampi Figures 5, 6, 7, 8, 9, and 10 are views of the parts in detail. v Like letters refer to like parts in all the views.

A is a bracket,-projecting lfrom a base, B, at right angles to each other, formed ot any suitable material, either cast or wrought, andV in one or two pieces; but if in two, must be firmly fastened together, either by rivets or bolts, as upon these two parts the other working parts are dependent. i

The buse, B, is of .sutlicient length and breadth to furnish a firm support to the entire machine, and is fastened by screw-bolts at each end, .as partially seen at a: x," g. 1, where the heads are recessed into the base.

The bracket A, projecting from the base, is strengthened by ribs at the rear or opposite to the clamp, as

'partially scenhat a, gs'l, and 2.

Slots S and s s, for holding and gui-ding the moving clamp, are also shown .in bracket A.

The clamp Gand C consists of `two jaws, of some material that will furnish an excellent friction-1l surface and at the sanne time be. sufficiently hard to resist so much abrasion from the ropes as to render it inoperative.

We prefer to forni the jaws of wood, set in such a position that the ends of the grain or growths shall bear upon the ropes or hawsers, as we lndthat by so doing very great holding-power is obtained.

The fixed jaw of the clump is recessed into. the base, B, as seen at C, fig. 1, and it=mny be {ixcd firmly, -either by being driven into a dove-tailed recess, as shown, or by any other suitable means.

The movable jaw, C', is fastened, in like manner, into a metal guide, G, shown at figs.` 1, 2, 7, and S, which is'provided with a rib, f, as shown at tige. 7 and 8, that ts nicely in the slotv S, and serves as a guide to it, in combination with the screw'bolts l. t, said bolts also holding it in. contact with the front face'of the bracket A, upon which it slides.

In a recess in the 4top of said guid s friction-roller, F, is mounted upon an airis,4 m, in order to relieve the friction that is caused by the pressing action of the working-lever L. y

Il is a movable block or box, placed within the opening or slot J ofl the bracket A, as seen in figs. 2 and 3, provided with a flange, 1', to prevent it from pressing througlrsnid opening or slot J. l u is a plate, corresponding with the flange ot'. the bot; H, placed on the opposite side of the opening d, having acircular opening in the centre corresponding with the opening in the centre of 'the block H,`througl1 both ot.' whichsaidcireu'lar openings the bolt N'passes, said bolt having a shoulder onA the front side ofthe block H, and furnished with Va nut on the b aclc side of thc Vplate u, thus securing both the block H and plate u rmly tothe bracket A, and at tho same' tiinc xuaking part of the bolt N, which servesns the axis or bearihg of the `cam or lever L. i n

The'head of said lever is formed of metal, and it is so cam-shaped that one working point will throw cr `force the guidi` G to a. greater'distance than its 'corresponding point on the other side.

It may operate by simply vtwo unequal eecentrics, working from the same centre, N, so as to clamp ropes of greatly-varying sizes, .but we prefer-.the cam so shaped that the pressure will increase beyond the throw of the lever. 1

Said lever may be made in one piece, or the .heed may be formed with a socket, as at O, figs. 1 and 2, into which a. ber or handle may be inserted when desired, as shown 1t-O, iig. 1.

The inner li'aceof said lever is recessed, as at R, figs. 4 and 2, so as to form n. iiang'e, n n n, on the inner face of which spiedo, igsf2 and 7, works, said pin being 'firmly fixed in the rib f of' the guide G, and by vwhich the' movable jaw of the clamp is drawn from the ropes whenever tlie'pressure is relieved.

This workingdever L is mounted upon the bolt oraxis N, which passes through the movable boxH, as shown in figs.v 2 and -1-0, and holds it in working position.

The movable box' H, as shown in figs. 2 and 1'0, is adjusted in the topof the bracket-A by screw-bolt I, as

'seen inzii 2. '.lhesaid movable box H has u. recess in its u cr ortiOn, where e. washer, W is laced, said g PP ,P P

Washenbeing firmly attached to screw-bolt I, whereby the lever L cnn be vraised or lowered, :is convenience may require, it sometimes being necessary lto give a'smaller or ,greater space between the two jews C and C' than the throw of the lever will allow.

The operation' is indeed veryeiinple,'a`ndl will now be readily understood by simply saying, that, when intended to be used on shipbonrd,' it may be placed anywhere in the position of the lines or lmwscrs'to be fest. cned, the clamp being opened by'throwing' the lever O into aline with thc slot S, or wherever the least distance exists between the centre, N, and the circumference n n mthepin p carrying the guide G, and moving portion of the clamp, C', with it'.- n v l The rope is then placed betwcen'the' two jaws, which may be slightly curved on the clasping faces, as scen et C4 and C', fig. 2, or when the lever is forced bnk toward any other position, 'either to the right or leftl the moving jaw, C', is pressed 'in a. corresponding degree upon the rope, and'may, at the pleasure of the operator, be held with any desired degree of firmness. This inventionwill be found very useful, also, in n great variety of .other places, such as derricks,'tnckles, clothes-lines, dto., die, 1-

And now, having thus briefly` but clearly described our invention, what we claim, and desire to secure by Letters Patent, s-

` The double cam-shaped levervL, in combinotion with the moving jew, C', when operating through the guide G and pin p, substantially os described, and for the purpose set forth.

C. FRED. GLADDING.
