Specification of Letters Patent. Patented J 111163118, 1918.

Application filed November 26, 19 17. SerialN 0. 204,065.

To all whom it may concern:

Be it known that I, JACOB BOLANDER, of the city of Toronto, in the county of York, in the Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Bag-Holders, and do hereby declare that the following is a full, clear, and exact description of same.

This invention relates to adjustable devices for the supporting of bags in an open condition to facilitate the filling of such bags, beingparticularly adaptable for such purposes as mail-sorting, grain-bagging and like purposes, and having as an object ,to provide a readily-operable and adjustable device of simple construction which will effect the supporting of a bag in a very secure manner, whereby liability of the said bag to slip, or he accidentally displaced, from the support will be materially obviated; an important object also being to arrange resilient gripping members in such relation tobag-supporting arms, with which they cooperate, that the pressure of the said gripping members may be concentrated at certain desirable points, upon a bag being supported by the device, to secure great efficiency in the said gripping operationtogether with certain other advantages which will be hereinafter pointed out. 1

Further objects subsidiary to or resulting from the above-mentioned main objects, or from the construction of the invention as it may be carried into effect, will become apparent as the invention is hereinafter further disclosed.

In carryingmy said invention into effect Imay provide, as an example, the novel construction and arrangement of parts whereby a frame or head is, preferably, slidably arranged and vertically adjustable upon a vertical support, said frame having hinged thereto, and disposed upon: either side thereof, a pair of outwardly-extending bag-supporting arms which may swing upon their hinges, over respective quadrants forming part of the base of said frame, one or both of which quadrants .may be provided with teeth with which suitable interlocking means, carried by the arm or arms, may detachably engage to determine the adjustment of the said arms with. respect to one another; and it is preferred that a link connection should beprovided between, and co-acting" with, the said arms whereby angular adjustment-of one of thesaid arms will be accompanied bvthe synchronous adjustment of the other of said arms, but in, an opposite direction thereto, as will be readily understood. The outer parts of the arms, thatis, the parts which are intended to actually'engage with the bag, are preferably somewhat raised above the plane of theinner parts of the'said arms in proxim1ty to the quadrants, whereby the rim of the bag may be folded thereoverso that the body of the bagv will depend between the arms, and gripping members secured to the said .arms adjacent to said quadrants and adapted to swing vertically out of operative position, may be arranged in such manner that, when in their securing posi-' tion, the outer ends of the saidgripping members are secured in contact with that part of a bag contiguous to' the outer ends of the supporting arms by suitable 880111 1 ing means, such as clips, against resilience:

in the said members, the said members also impinging upon the said bag at points substantially removed from the extremities of the said arms, whereby the resilient forces, in the said arms, areconcentrated at these points, and also clearance provided between, the gripping members and the supporting arms, intermediate of the said points of resilient contact therebetween and the points of contact at the extremities thereof, all off which is more particularly described {and ascertained hereinafter, having reference to the example illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view I of the arms, grippers and the same,

a hopper shown which may be used in con- 7 nection therewith where desirable.

Similar characters of reference indicate similar parts in the several figures of the drawings.

1 is a vertical support and 2 a frame or head vertically adjustable on the said support 1, adapted tobe locked in any such vertically-adjusted position by means of the thumb screw 3, the form of frame shown in the drawings being characterized by quadrants 2 and 2*, one of which is serrated or toothed near its periphery, a pair of radial hinge housings 2 and .2 and. a pivotlugQfi extending upwardly from the base of said frame intermediate of the said quadrants 2 and :2". Hingedly mounted on pins at and 5 respectively through the hinge housings 2 and 2 are outwardly extending arms 6 and 7 hereinafter called the bagsupporting arms, vertically ofi'set intermediate of their length, whereby shoulders 6 and? are provided, and preferably substantially oflset laterally in proximity to the said shoulders,

as will be readily understood from an examination of Fig. 2 of the drawings, that is to say, the said bag-supporting arms have each a lateral S bend therein whereby the distance between the said arms is substantially increased intermediate of their length. It will be seen that the said bag-supporting arms 6 and 7 are capable of swinging over the quadrants 2 and 2 respectively, and in order to synchronize the movement of the said arms toward or away from one another, a link connection therebetween' may be provided comprising a pivoted lever 8 mounted intermediate of its length upon the pivot lug 2 already referred to, and having one end connected by a link 9 to the arm 6 and the other end by a further link 10 to the arm" 7. The said lever 8 is preferably pivoted at a point somewhat nearer the end carryin'g the innermost link 10 in order to secure an equal movement of the two arms.

It will be seen that the arms, as constructed, permit abag to be supported there-between while the rim of the bag may be folded thereover to engage with the said arms in the manner as particularly indicated in Fig. 3 of the drawings, so that if a bag be so supported by the said arms and the arms be; distended as far as the rim of the bag will permit, then an appreciable downward force in the body of the bag would be required to remove the same from the said supporting arms, due to the binding efi'ect of the folded rim thereon.

In order to insure a very efficient gripping of the" bag upon the arms, grippers 11 and 12 are provided, in the form of resilient metal strips hinged at 13 and 14 to the inner parts of the said arms 6 and 7 respectively, the outer ends off-he said grippers having clips 15 and 16- mounted thereon to engage with the outer ends of the said bag-supporting arms, when the grippers 11 and 12 are brought into operative position. It will be seen from an examination of Fig. 2 of the drawings that the laterally offset part of each arm passes somewhatbeyond a plane between the hinge 0f the respective gripper and the end of the arm, with which the clip carried by the said gripper engages, so that, when bringing the clips into engagement with the arms, the said grippers will first contact intermediate of their length with the laterally ofi'set parts (forming stops for said grippers) of the said arms, whereby the completion of the closing of the grippers against the arms must be effected against the lateral resilience of the said grippers; and the arms may be so shaped that when the grippers are so secured in their operative position, clearance is provided, between the grippers and the respective arms, intermediate of the said points of resilient contact therebetween and the points of contact at the extremities thereof, these features being all illustrated in the said Fig. 2. The hinged natureof the grippers permits them to-be swung upwardly so that they do not interfere with the adjusting of the rim of the bag upon the gripper arms prior to bringing the said grippers into operation.

In Fig. 3 of the drawings a hopper l7 is shown which may be very conveniently used with the device described, said hopper being carried by a ring 18 revolubly mounted, upon the support 1, whereby the hopper may be swung out of position during the adjustment of the arms and grippers.

By the use of this invention, a bag may be supported in such manner that the frictional resistance, due to the folding of the rim thereof over supporting members, is employed, to effect the securing of the bag against displacement, in combination with the concentration of resilient force at certain desirable points, together with thesecuring, by clips, of the bag at the extremities of the supporting members; and the relative arrangement of the arms and their respective grippers, whereby clearance is provided th'erebetween throughout part of their length, while contributing to the concentration of forces already described, also permits bags having heavy seams therein to be used with the device without lossof'eflt ciency so far as the mechanical operation of the device is concerned.

This invention may be developed within the scope of the following claims Without departing from the essential features of the said invention, and it is desired that the specification and drawings be read as being merely illustrative and not in a limiting sense, except as required by the prior art.

What I claim as my invention is:

1. In a bag holder, a pair of bag-supporting arms provided with upwardly ofi'se't portions over which the rim of a bag may be folded, grippers secured at their inner ends to said arms, said grippers, when operative, extending along the outer surfaces of the upwardly offset portions of said arms, and

locking means carried at the free ends of the grippers to engage the arms.

2. In a bag holder, a pair of bag-support ing arms provided with upwardly offset portions over which the rim of a bag may be folded, and grippers hingedly secured at their inner ends to said arms, the outer ends of said grippers bemg'adapted to en age the upwardly extending ofiset portions of said arms to bind the folded rim of the bag thereon.

3. In a bag holder, a laterally ofiset bagsupporting arm, a laterally elongated gripper secured at one end to said arm, and

' means to detachably secure the free end of said gripper to said arm, whereby when the gripper is attached at both ends to the arm the intermediate portion thereof will impinge against the lateral oflset in the arm and the closing of said gripper is eifeoted against the resilience thereof.

4. In a bag holder, a bag supporting arm,

gr pper interme iate of its length, Whensaid ripper is partly closed on said arm, wherefiy the full closing of said gripper Will be effected against the resilience thereof.

Signed at the city of Toronto, in the county of York, in the Province of Ontario, in the Dominion of Canada, this 20th day of November, 1917.
