13 Claims.

My invention relates to improvements in fastening means for securing assembled partitions, walls, beams, troughs, and for other purposes,-- the present invention being a division of my copending application Ser. No. 687,364, filed August 29, 1933, for I-Iuller feeder, or the like.

Briefly stated, the present invention has among its objects (1) to provide a fastening means which will be very efficient for holding in rigid assembly partitions, walls, beams, troughs, and the like, such as are incorporated in cotton gins, feeders, etc., and which will eliminate the necessity of using angle iron brackets or providing securing flanges on the parts; (2) to furnish a device as characterized which is simple, inexpensive, strong, durable and easy to install; and (3) the provision of a fastening means the use of which leaves no undesirable openings in the partitions between adjacent compartments.

The foregoing and other objects are attained by means of the novel combination and arrange ment of parts to be hereinafter described and claimed, reference being had to the accompanying drawing forming a part of this specification.

While the drawing and the following description are directed to particular examples of the invention, it is to be understood that same is susceptible of other mechanical expression within the spirit and scope of the subject matter claimed hereinafter.

In the drawing, wherein the same reference characters have been used to designate the same parts in all views.

Figure 1 is a sectional view through a pair of angularly disposed wall or partition members .and illustrating one element of my securing means partially in place;

Figure 2 is a sectional view similar to Figure 1, but showing the complete fastening means in operative position;

Figure 3 is a perspective view of a wall or partition member partly broken and partly in section, showing one element of my fastening means in place;

45 Figure 4 is a view similar to Figure 1 but disclosing a slightly modified form of the invention;

Figure 5 is a view similar to Figure 2 but disclosing the modified form of Figure 4;

50 Figure 6 is a view similar to Figure 3 but directed to the form of device of Figures 4 and '5;

and

Figure '7 is a cross-sectional View taken on the line 1-1 of Figure 5.

Referring to the drawing by reference characters, and turning first to Figures 1-3, inclusive, 9 designates a portion of what may be an end wall of a cotton gin while 36 designates what may be an angularly disposed partition or the like. Heretofore, the securing of these, or similar, elements in rigid assembly has required that one of such elements be formed with attaching flanges, or some special seat for the other member; or, alternatively that angle iron brackets be employed. By the present invention I am enabled to, do away with the foregoing, and thus effect considerable economy in cost of material; also in time required to assemble a machine such as, for instance, a cotton cleaner.

In carrying out the invention according to Figure 1-3, inclusive, I employ the securing element 52, which is preferably substantially U- shaped in cross-section, as indicated in Figure 3, to provide an elongated channel 53 which is adapted to receive the shank 54 of a bolt as indicated in Figure 2. The member 52 is preferably of metal and may be either a stamping or a casting whose walls at the open side of the device are cut away inwardly from one end to provide opposite shoulders 5I Adjacent the opposite end of the device the laterally projecting flanges are provided as indicated at 5|.

Securing element 52 is designed to be anchored to one of the partition or wall members 9, 36 and to this end, as shown in the drawing, I provide the partition member 36 with the cutout 50, which will be sufficiently wide to admit of the passage therethrough of the lower or small end of the fastener 52 from'the left of partition 36*, as shown in Figure 1; but not wide enough to permit passage of the side flanges 5|.

Such opening or cutout 50 may be of any length but for reasons which will presently appear, it will preferably be made no longer than actually necessary to admit of fastener element 5| being rocked into place about the lower end wall of such opening as a fulcrum for the opposed shoulders 5P of such element 5|. Preferably the upper end wall of opening 50 will be arched as at 5!) to generally approximate the contour of the rear or bight portion of member 52 to reduce, as much as possible, the width of the upper end of such opening, which is not actually occupied by member 51 when it is in place as shown in Figure 2.

The fastening member 52 having been asseme bled in the opening 50 of partition 36*, as described, the bolt 54 is inserted in the channel 53 from the inner end thereof. Bolt 54 is made longer than the channel 53 so that its end will project through the hole 54 in the other wall or partition member 9 to receive the nut 55. As shown, the bolt 54 has the head 54 which engages the inner end of member 52 so that when the nut 55 is tightened up against the outer surface of wall 9, the shoulders 5| will be drawn tightly into engagement with the adjacent end of opening 56 so as to draw the inner end of partition 36 tightly into engagement with the proximate surface of the wall or partition 9. In order that the outer end of member 52shallengage wall!) to furnish what might be termed alateral V or seating projection of wall 36 (after the fashion of a fiange) to make for a more rigid assembly,

equal to the distance from the plane end of opening 50 to the adjacent end of partition 36 l In many constructions such as cotton cleaners and the like,the substantially airtight sealing of certain compartments from one another is a thing of importance; By restricting the length of my opening 50 in the wall or partition member 36 and further by arching the upper end thereof as at 50 to about conform to the contour of the rear or bight portion of member 52, I leave but a small arched space (see Figures 2 and. 3) aboverthe upper'end of member 52 when same is in place. The head 54 of bolt 54 is flattened at one side as at 54* and is made sufficiently thick and wide that its flat side 54".will completely overlie and close this space as indicated in Figure 2. By making the opening 5i as short as possible and by arching its upper end, I am able to keep down the dimensions of the head 54 of the bolt 54.

Figures 4- 7, inclusive, are, as heretofore indicated, directedto a slightly modified form of the invention. 'Here, instead of member 52 with its plane upper end which makes a right angle with the body of the device, I employ the member 62 whose upper end wall is beveled downwardly and rearwardly in a curve as indicated at 62*. This formation obviates the necessity of arching the upper end of the opening 50 like at 50 in the first described form of invention. Fastener member 62 provides the shoulders 6I and lateral flanges 6| corresponding to parts 5l 5| of Figures 1-3, but its lower end instead of being plane or'sub'stantially so is out inwardly on an upward bias from its rear or b ight portion, as best shown in Figure'5, so that only the rear point 62 makes contact with the face of the wall 9.

Bolt 64 differs from bolt 54 in that its head 64 is enabled to be made thinner than head 54 of bolt 54 because the curving of the upper end of 62*a-s at "62 leaves-a smaller space to be covered by the bolt head when 62 is in place. It has a flat 'side 64 corresponding to the similar formation 54 of bolt 54.

The operation of the device of Figures 4-6 produces an action by way of addition to that of the Figure 1 device by virtue of the fact that the bolt head 64 makes contact with the inner part only of the upper endof the device '62, While the lower end of the device 63 makes contact with the wall only at the rear point 62. Thus, when nut 65 is tightened up the combinedaction of

bearing points

62 and 62 is to affirmatively force the flat bolt head side 64 and the open face of the device against the wall or partition 36, and also of course todraw the partition against member 9.

v The use of my fastening means enables partitions, troughs, or other divisions 9, 36 to be readilyncut' to exact length and the

holes

50, 54 punched. Thereafter the partitions, say 36 for instanca oan be very readily given a trough or "other shape as the holes 56 (or 54) do not interfere with this operation as would the usual end flanges. My method of fastening not only reduces the cost of preparing the parts for assembly (as above described), but it also reduces the time required for assembly. Obviously, the boltreceiving channel 53 may have a flat rear 'wall.

instead of a rounded one.

min theforegoing description taken in connection with the accompanying drawing, it is believed that the advantages of my device will be readily apparent to those skilled in the art. The device is obviously available to a wide variety of uses in many arts. I have made the

devices

52, 62, U-shaped in form-and with other specific details of construction, yet obviously many radical changes in structural detail may be made without departure from the invention claimed,
