V Specification of Letters Patent.
Patented Mar. 11; 1913.
Application filed October 5, 1910. Serial No. 585,506.
T 0 all whom it may concern Be it known that I, GEORGE C. HA'RinsoN, citizen of the United States, residing at Elyria, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements inBag-HOlders, of which the following is a specification.
My invention relates to clamping devices whereby a member may be supported upon a standard at any desired height thereon and easily detached from its locked engagement with the standard so as to permit it to be shifted upand down on the standard, and while the clamping device forming the subject-matter of this invention is particularly adapted to bag holders, I do not wish to be limited to this application of the invention.
Figure 1 is a perspective View of my improved bag holder. F 2 is'a detail fragmentary elevation part y in section of the standard and the bag support.
Referring to these figures 2 designates a standard formed of iron pipe of any suitable height. The lower end of the standard is screw threaded and engaged with a T 3, which in turn engages with the laterally extending pipes 4 forming the cross bar of the standard. These pipes 4 at their ends have screw threaded engagement with the Ts 5. and engaged with the ends of the Ts '5 are the pipes 6 and 7, these pipes being pro-v vided at their ends with the elbows 8 forming the feet of the base.
Shiftably mounted upon the standard is the transversely extending bar 9 whose ends are angularly bent as at 10 and form spreaders for the bag to hold it open. In order to engage the bag upon the Spreaders I provide the angular members 11, each of which has the outwardly projecting flange 12 which extends over the upper edge of the angular terminations 10 of the bar 9-. These angular portions 12 of the strips 11 not only project over and beyond the faces of the terminations 10 but also project rearward as at 13. The relatively sharp edges of the flanges 12 and the projecting portion 13 engage with the material of the bag and hold it firmly upon the bar 9. The bar 9 is secured upon a sliding head 14 having the longitudinally extending elongated slot 15 on its rear end. he dowgnwardly extending bill 16 upon its forward mwhose inner face is coincident with they front end of. the
slot 15. The standard2 passes upthrough 16 contacts withthe standard 2. The forward end of the head 14: is transversely extended as at 17 and is held to the bar 9 by bolts 01'' nuts 18.
In order to holdthe head 14: in sliding this slot 15 and/fthe inner face of the bill engagement with the standard 2- and yet. permit the head to be locked or clamped at any desired point upon the standard 2, I provide the locking device illustrated in Fig. 2 and consisting of a wedge 19 extend ing down through the slot 15 behind the standard, the upper edge of the wedge be ing provided with the outwardly extending tail 20, the upper face of which, is downwardly inclined. A coil spring 21 is disposed between the upper face of the head.
14 and the under face of the tail 20, the head being formed with a socket in which the .lower end of the spring rests. That face of the'wedging member 19 which engages with the standard 2 has a straight portion 22 and is then cut away as at 23, it having another slightly inclined portion 24 below this cut away part The outer face of the wedg ing member 19 is outwardly and downwardly inclined as at 25, the face. being slightly curved. The outer end wall of the slot 15' is upwardly and inwardly inclined toward the standard 2 and this upwardly and inwardly inclined face engages with the outwardly and downwardly inclined face 25 of the wedging member. Thus as the wedging member is drawn upward it will be wedged into clamping engagement with the standard 2, while when it is forced downward it will be released from said clamping engagement and shifted laterally a sufiicient distance to permit the head 14: to be easily slipped up and down upon the standard. The spring 21 of course acts to shift the wedging member upward and into its clamping engagement, and by pressing downward upon the tail 20 and compressing the spring, the wedging member is moved downward and out of its clamping engagement so that the head may be easily shifted. By then releasing the tail the spring 21 will throw the wedging mem her into its clamping engagement. While the means so. escribed will hold the head set or clamped in any vertically adjustable position, it will-not prevent the head from rotating upon the standard, and to the end that .the head maybe .held from rotation after it has been set, I provide the set screw I 26 which. passes through the, rear endof the not by this bill 16. this bill forming a bracket and giving a. more extended bearing to the bag support and head, thus preventing the head from yielding even slightly when the L bag is filled.
In order to prevent the head from being removed from the standard, I screw thread the upper end of the standard as at 27 and engage therewith a cap 28. Disposed below this cap 28 and held in position by the cap, is the knife blade 29. the outer edge of which is inclined, this inclined edge and the upper edge being sharpened. This knife blade 29 is inserted in a slotformed in the upper end of the standard. After the bag has been filled and tied, the cord may be easily cut by raising the bag and bringing the cord in contact, either with the upper or inclined face of the knife blade. It will be seen from Fig. 2 that the wedging member 19 projects above the upper face of the head 14: and that when thehead 14 is moved up ward to its full extent, the upper end of the wedging member will contact with the cap 28 before the upper face of the head can contact with the knife blade 29. As a consequence there will be no danger in moving the head upward or blunting the edge of the knife.
In order to provide a support for the bag hostages I mount upon the outwardly extending legs 7 the flat cross bar 30. This cross bar at its ends is upwardly bent and curved over the pipes forming-the legs 7 and is attached to these legs by means of the bo1ts.31 which pass downward through the legs.
What I claim is:
The combination with a standard, of a head having an elongated slot through which the standard passes, the rear end of the slot being upwardly and inwardly inclined, a wedging member located in the slot and projecting beyond the same at both ends. the outer face of said wedging member being outwardly and downwardly inclined, the upper portion of the inner face of the wedging member conforming approximately to the standard, the intermediate portion of the wedging member being cutaway and the lower portion of the wedging member having its'inner face upwardly and outwardly inclined to form an angularly disposed lower terminal bearing against the standard and spacing the intermediate portion of the wedging member therefrom, the upper end of the wedging member-being formedwith an outwardly and downwardly projecting tail providing means whereby the wedging member may be manipulated, a spring supported in a socket in the upper face of the head and engaging the end face of said tail and housed by the tail, and a set screw passing through the head and engaging the wedging member to force it into binding contact with the standard.
In testimony whereof I aflix my signature in presence of two witnesses.
