BAG HOLDER. APPLICATION FILED MAY 1. 1914.

ROBERT LEWIS SMITH, OF TORONTO, ONTARIO, CANADA.
' Specification of Letters Patent.
Patented Jan. 22, 191%.
Application filed May 1, 1914:. Serial No. 835,636.
To all whom it may concern: 7
Be it known that I, ROBERT LEWIS SMITH, a subject of the King of Great Britain, and resident of the city of Toronto, county of York, Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Bag-Holders, as described in the following specification and illustrated in the accompanying drawings, that form part of the same.
The principal objects of the invention are, to facilitate the filling of bags and sacks, and to devise a holder to which the bag may be very easily and quickly applied and held in a perfectly secure manner.
A further object is to devise a form of liller which may be utilized in any desirable 7 position either with or without a stand.
The principal feature of the invention consists in the novel construction and arrangement of parts, whereby the bag is firmly clamped to the filling hopper and whereby said hopper and the bag attached thereto are supported in position ready for filling.
In the drawings, Figure 1 is a perspective view of my improved bag holdershowing the means for supporting same and the means for holding the bag in place.
Fig. 2 is a perspective view of the holder shown on a smaller scale and showing the use of a stand support therefor.
Fig. 3 is an underside plan view of the holder showing the bag clamping members in the closed position in full lines and in the open position in dotted lines.
Like numerals of reference indicate corresponding parts in each figure.
Referring to the drawings, 1 is a hopper formed with a straight portion 2 at one side thereof and a centrally arranged cylindrical portion 3.
tremities 7, said hook members being adapted to fit over and rest upon the edge of a grain bin or about any other suitable form of support.
The hook members extend vertically downward from the bar t and are bent inwardly and rigidly secured at their lower ends to the curved bar 5 presenting the straight vertical portions 8 which form the substantial supports to hold the hopper in a horizontal position.
9 and 10 are a pair of bridge bars extending between the lower ends of the hook members 6 and rigidly secured thereto, the upper bar 9 being bent upwardly from the supports and the lower bar 10 being bent downwardly. V
11 are a pair of rods shaped to the contour of the cylinder portion of the hopper and adapted to fit into the annular groove 12 in said cylinder portion, the rear ends 12-3 of said bars 11 are-bent upwardly at right angles to the curved portion and extend through the bridgebars 9 and 10 which serve as journals for the support of said rods. The rods 11 are held in place in the bridge bars 9 and 10 by suitable cotter pins 14-. r
The outer ends 15 of the rods 11 extend outwardly from the hopper in substantially parallelrelation the one to the other and form handles by means of which they are swung to their closed position.
16 is a bracket secured to one of the handles 15 having the yoke portion 17 surround ing the rod in which the loop end 18 of the latch 19 is arranged, said looped end of the latch encircling and pivoting on the rod.
The latch 19 is preferably formed of a piece of thin metal twisted edgewise from the loop 18 and provided with ratchet teeth 20 adapted to engage the other handle.
21 is a bolt secured centrally in the lower bridge bar 10 and supporting a coil spring 22, the ends of which extend laterally outward and are formed with the hook ends 23 which hook around the laterally extending portions of the rods 11 to swing said rods outwardly clear of the hopper.
In Fig. 2 I show a stand for supporting the filler. This stand is formed of a pair of crossed leg members 2% which are connected at the top to a ring 25 adapted to lit under the rim 26 of the hopper, said ring having 29 are brace rods secured on their upper I ends to the ends of the bar 28 and extend angularly downward crossing each other and are connected to the leg members 2% to prevent them from spreading.
In the use of this device the hopper in the simple form shown in Fig. 1 may be hooked on the edge of a bin or on to a wagon orany other suitable place and is thus held rigid in a horizontal position. The ratchet holding the curved rods 11 is released and the springs swing said rods outwardly ontheir pivots clear of the cylinder portion 3 of the hopper, the bag which is to be filled being then slipped over the cylinder portions and the rods are then brought together by means of the handles and held securely by the latch 19, thus firmly holding the bag in place and suspending the same in a desirable position for filling.
The grip of the rods 11 is sufficient to hold any ordinary form of bag even when filled. When the bag is filled the handle ends 15 of the rods 11 are sprung together and the latch 19 released by pressing downwardly with the thumb or finger onthe outer end opposite to the ratchetportion. When the handles are released the bag is released and frees itself instantly.
hen it is desired to use the holder where there is no ordinary support, such as a bin or wagon box, the stand comprising the legs 24 and the ring 25 is set up and the hopper dropped into said ring. The bag is then suspended in its vertical position wherever it may be desired to place the stand.
It will be readily seen that immediately on the release of the ratchet latch the ends of the springs 22 are forced'outwardly clear of the cylinder portion so that the bag may be very readily placed thereon and when the open end of the bag is placed in position the rods are swung inwardly and locked gripping the bag securely.
The legs of the stand are made adjustable longitudinally to accommodate long or short bags toiallow the bottom of the bag to rest onthe ground while it is being filled or to insure the holder standing in a proper position if located on' uneven groui'id.
'W hat I claim as my invention is l. A bag holder, comprising, a rigid frame having hook supports on one side, a hopper secured to said frame on the side opposite to said hooks, and arms .pivotally secured to said frame and. extendingaround said hopper and adaptedjto gripthebag.
2. Av bag holder, comprising, a rigidsupporting frame, a hopper secured to said frame, a pair of semi-circular clamping arms pivotally secured at one end to said frame and encircling said hopper, a spring member secured to said frame and'connected with said arms andadapted to swing them outwardly from the hopper toel'ear the bag, and means for clamping said arms to hold the bag.
