PATENT OFFICE.

JACOB PAWOLOWSKI, OF CINCINNATI, OHIO.

LINE-ANCHOR.

Specification of Letters Patent.

Patented June as, 1908.

Application filed September 28, 1907. Serial No. 394,245.

To all whom it may concern:

Be it known that I, JAooB PAWOLOWSKI, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Im rovements in Line-Anchors, of which the fol owing is a s ecification.

My invention re ates to improvements in fasteners, and particularly to that class of fasteners which are adapted to clutch and hold a line, such as rope, wire, or the like.

The object of my invention is to provide a simple, inexpensive and durable device which is convenient and effective in operation and use.

My invention consists in angularly disposed adjacent members, and a lever, block, pivotally mounted on one of said members, and adapted to co-act alternatively with the other member, to clamp a line against it, depending upon the direction of greatest tension on the line.

My invention also consists in the details of construction and arrangement herein set.

forth and claimed.

In the drawing: Figure 1 is a perspective view of a line anchor embodying my invention, secured upon a vertical support, in position for use. Fig. 2 is a perspective view ofthe lever block used in the above. Fig. 3 is a side elevation of the pivot used in the above. Fig. 4 is a perspective view of a simpler construction embodying my invention. Fig. 5 is a perspective view of the leaction of eac while supported between two of them in the ver block used in the construction shown in Fig. 4. Fig. 6 is a perspective view of the pivot used in the construction shown in Fig. 4. Fig. 7 is a plan view of the device showing the line clamped therein, and Fig. 8 is a plan view showing the line in position in the anchor and exerting equal tension upon each arm of the lever block, the lower edge of the lever block being'represented by a dottedline in each instance. Fig. 9 is a perspective view showin two anchors illustrating the anchor when the line breaks manner ustrated in Fig. 8. Fig. 10 is a perspective view illustrating the manner of removing the line from the anchor.

In the construction of my device, as shown in Fig. 1, a body 1 is formed of angularly disposed members 2 and 3, each of which is provided with screw openings 4 and 5, respectively. The member 2 is rovided with a bracket 6 having a suitab e pivot bearing therein, and the other member'is preferably provided with a knurled or roughened surface 7; The lever block 8 is provided with a recess 9 to permit it to enter the embrace of the bracket 6, so that the bracket does not extend above the edge of the lever block 8 adjacent the member 3, and thus interfere with the insertion and removal of the line, in the use ofthe device, and is mounted upon a 'pivot 10. Thus the pivot is supported at both ends, making a strong construction. The arms 11 and 12 of the lever block 8, are preferably tapered from top to bottom, so that their surfaces are inclined towards the surface of the angularly disposed member upon which said lever block is mounted, for the purpose of facilitating the prevention of accidental disengagement of the line 13 from the anchor. If desired, the body may be constructed Without the bracket 6 and the lever block without the recess 9, as shown in Fig. 4, in which construction the lever block 8 is mounted on the member 2 of the body by means of the pivot 10 in this case provided with a shoulder 10 to properly support it. The members 2 and 3 are both provided with screw openings in order to enable the anchor to be mounted either upon a horizontal or vertical support, whichever is available or most convenient, and the anchor may be secured to its support through these openings by screws 14 or other suitable fastenings. The corners of the lever block 8 are rounded to prevent damage to the line 13 and to facilitate the placing of the line in the anchor and its removal therefrom.

The lever is mounted upon one member of the body far enough from the other member to permit the line to be easily placed within the space 15, and a very slight movement of the lever upon the pivot will cause it to grip the line between one of its arms 11 or 12 and the roughened or line engaging surface 8, whereby the line is clamped by the pressure exerted by itself on the other arm, so that the clamping power is increased by increase of tension on the line in this manner.

To secure a clothes line or other line, in position for use, simply place the line between the lever and line engaging surface of the the other arm, such as 11.

Thus, it will be seen that tying the line at any point is dispensed with and the use of loops and knots avoided. To remove the line, simply take hold of the stretched portion of the line near the arm of the lever which is not co-acting with the member 3, and draw the line upwardly and outwardly from the space 15, as illustrated in Fig. 10.

A desirable feature of my invention consists in the fact that the lever is double acting and will grip and hold the line regardless of the direction of the tension thereof. Thus, when a line is stretched continuously around several such anchors, in case the line should break between any two anchors, by which the tension is relieved on one side of the anchor, releasing one of the arms, the line will at once be gripped between the other arm of the lever and the line engaging surface. This action takes place in both anchors adjacent the break, and thus the other sections of the line are securely held in position, confining the fall of the line, and the consequent damage, to that section of the line where the break occurred.

As shown in the drawing, the lever blocks with their arms take the form of prisms whose sides are straight and regular, and it will be understood that the shape of the lever may be modified to adapt it to the difierent constructions, such as the variations of the pivotal mounting hereinbefore described and illustrated in the drawing, and the position of the pivot relative to the surfaces of the arms which are adapted to make contact with the line, may be varied. However, neither the shape of the lever blocks nor the position of the pivot should be varied to such an extent as to allow the lever block to am the line in the space 15, but should always hold the line between one of its arms, such as 12, and the angularly disposed member, such as 3, by virtue of the pressure of the line on Then the line will be released automatically by the removal of its pressure on the arm 11, without injury. This device thus constructed with the lever block of substantially prismatic formation with the pivot comparatively close to the angularly disposed member with which the lever block is adapted to co-act, is peculiarly adapted for stretching a line obliquely of a s ace where it is to be used, the line anchors fieing disposed along either side of the space for supporting the line in such position. When the line is thus stretched obliquely of the space at the proper angle, the automatic clamping of the intermediate anchors, in case of breakage of the line in any section, is insured, due to the pressure of the line on the lever blocks, as above described. At the same time, the terminal line anchor thus used may be de ended upon to hold the ends of the line at a times except when the line is removed from bearing on the lever block, as described, and as illustrated in Fig. 10 of the drawing. While thus being effective, the simple construction of the device adapts it for economical production, the tapered prismatic formation of the lever block being especially convenient in casting.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a line anchor, a body composed of angularly disposed members and a lever block pivotally mounted on one of said members and adapted to co-act with the other of Said members, both of said members being provided with openings by which said line anchor is adapted to be attached in operative position on either of two surfaces angularly disposed to each other, substantially as and for the purposes specified.

2. In a line anchor, an ularly disposed ad jacent members, and a ever block of substantially prismatic formation pivotally mounted on one of said members whereby it com rises arms adapted to co-act alternative y with the other of said members, substantially as and for the purposes specified.

3. In a line anchor, a body composed of angularly disposed members, and a lever block of substantially prismatic formation pivotally mounted on one of said members, said lever block having rounded corners adapted to co-act with the other of said members and said corners being longitudinally inclined, substantially as and for the purposes specified.
