Description

MayA 2, 1961 F; H. KAUFMANN LOOM HARNESS Filed Feb. 18, 1959 ENT *L BY I Z 7 ATTORNEY through the top rails of the harness frames.

LooM HARNESS i Frank H. Kaufmann, Huntington Valley, Pa., assigner to Steel Heddle Manufacturing Company, Philadelphia,

Pa., a corporation of Pennsylvania Y Filed rer. 1s, 1959, ser. N0.`794,030 s claims. (cl. lssss) This invention relates to loom harness andA more particularly to improved connections between the harness frames and thesupportingand/or actuating partsof the harness. f

lt has heretofore been common practice in loom harness toprovide supports intermediate the ends of the top rails of theloom harness frames. Such supportsusually consisted of hooks or'the like connected to or extending Such supports were difficult of access because of their locations. The distribution of the weight in harness frames supported intermediate their ends also tended to bend or stress the top rails so as to cause deformation thereof.

No suitable provisions have heretofore been available for connecting the supporting devices or actuating straps of the harness to the harness frames at the ends of the harness frames in a manner which would permit of adjusting the harness frames to level condition, or of raising or lowering the harness frames to a limited extent while still avoiding any tendency of the connectors or parts thereof to foul with adjoining harness frames or the supporting or actuating devices for the harness frames.

It is the principal object of the present' invention to provide an improved mounting construction for harness frames which is carried on the ends of the harness frames so as to be readily accessible at the ends, and by which the forces between the harness frames and the harness are directly effective at theV side struts of the harness frame. v

It is a further object of the present invention to provide an improved connector for harness frames in which the connector forming part of the mounting structure is held against sidewise displacement or turning so as not to become entangled with adjoining harness frames or harness frame supporting or actuating devices.

It is a further object of the present invention to provide an improved connector carried on a loom harness frame which is held against turning or sidewise displacement and which is readily adjustable vertically at the end of the harness frame.

Other objects and advantageousfeatures of the invention will be apparent from the description and claims.

The nature and characteristic features of the invention will be more readily understood'from the following description taken in connection with the accompanying drawings forming part thereof, in which:

Figure l` is a front elevational view of a loom harness frame embodying the main features of the present invention; v

`Fig. 2 is a fragmentary perspective view of a portion of one of the upper corners of the harness frame showing the details of construction of the connector in accordance with the present invention;

Fig. 4 is a fragmentary vertical sectional view taken approximately on the line 4-4 of Fig. 3; and

Patented May 2, 1951 Fig. 5 is a fragmentary end elevational view of the structure shown in Fig. 4. j v

ltflshould, of course, beunderstood that the description and `drawings herein are illustrative merely, and that various modifications and ychanges can be made in the structure disclosed without departing from the spirit of the invention. j

v Like numerals refer to like parts throughout the several views. j

Referring now more particularly to the drawings,v in the embodiment of the invention therein` illustrated, the top and bottom rails 10 and 1l of a loom harness frame are shown as connected at their ends by meansfof side struts 12 which may be of any preferred construction. Y

For example, the same may be made of two strips 12a and 12b secured to each other and having their respective ends bent at rightangles as at l3rand 14 and secured on the inner'and outer edge portions of the ends of the top and bottom rails 10 and 1l by screws 15.

The harness frame, in spaced relation to the top and bottom rails 1t! and 11 can have upper and lower heddle supporting rods i6 mounted therein with their ends engaged in openings 17 in the side struts l2 and held against displacement along their longitudinal axes by re-` silient clips 13 mounted on the inner edges of the top and bottom rails 10 and il. The clips 18 can have end portions 19 engaged in notches 20 in the heddle supporting rods 16.

The heddle supporting rods 16 can be provided, in the customary manner, with heddles 2t of the type made of thin flat strips of metal with mortices for mounting the heddles on the supporting rods and with central warp supporting eyes of well-known type.

The outer sidestrut strips 12a are provided, preferably at locations aligned with the inturned ends 13 of the inner strut strips 12b, with outwardly disposed horizontal projections 22 to which upwardly extending side strip portions 23 are connected and from which inturned horizontal projections 24, parallel to the projections 22, are connected as a continuous and integral part of the strut strips 12a.

The

horizontal projections

22 and 24 on each Side of the harness frame are provided with aligned

openings

25 and 26 for the reception of the shank portion 27 of v a hook 28.

Nuts

29 and 30 are in threaded engagement with the shank portion 27 and thus adjustably engage respectively with the outer upper face of the vprojection 24 and thelower outer face of the projection 22 for permitting vertical adjustment of the shank 27 and for the locking of the shank 27 at the desired position of` adjustment.

` which an upright portion 32 extends close to the strut strip 12a, and an outwardly and downwardly projecting portion 33 in the same plane as the hook portions 2*?, 31 and 32, and for disposition in a plane parallel to the main longitudinal plane of the top rail 10 for engagement of the supporting or actuating structure such as a spring, harness strap, or the like (not shown).

On the upper faces of the strut ends 14, holding strips 34 are secured and are preferably held in position by the same screws 15 which retain the strut ends 14 in engagement with the top rail 10. The holding strips 34 have a downwardly extending bifurcated end 35 parallel to the end of the top rail 10, with the bifurcations disposed on opposite sides of the upright portion 32 of the hook Z8 to prevent the turning movement thereof.

It will be noted that the hook V23 can be adjusted vertically with respect to the top rail 10 by adjustment of the

nuts

29 and 30 which nuts also serve to hold the hook 28 locked in adjusted position. The location of the hook 28 and the

nuts

29 and 30 at the ends of the harness frames provides easy access for adjustment. The hooks 28 are retained against turning by the engagement of the upright portions 32 inthe bifurcated end 35.

The hooks Z8 are also prevented from moving or turning topositions such that they could engage with adjoining harness frames or harness supports or actuators.
