'BAG-HOLDER Specification of Letters Patent.
Patented May 15, 1917,
Application led August 9, 1916. Serial No. 114,012.
To all whom t may concern;
Be it known that I, CORNELIUS SCHREARS, a citizen of the United States, residing at Tolna, in the county of Nelson and State of North Dakota, have invented new and useful Improvements in Bag-Holders, of.
simplify and improve the construction, ar
rangement and operation 'of the detailed parts of the device.
In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is 'necessarily made to the precise structural details therein exhibited, but that changes, alterations and modiications within the Scope of the claims may beresorted to when desired.
In the drawings,-
Figure 1 is a vertical sectional view, partly in elevation, of a device constructed in accordance with the invention. i
Fig, 2 is a top plan view of the same.
Fig. 3 is a t'op plan view of the'base of the device. Y
Fig. 4 is a detail view in side elevationof` one of the scales or weighing-devices..I
Fig. 5 is a sectional detail view taken ioii members 37 on which arms A are pivotally the line 5-5 in Fig. 2.
Fig. 6 isa sectional :detail viewitakeini on the line- 6 6 in Fig. 1. f
Corresponding parts in the several l:iigures are denoted by like characters of reference. i
The base of the improved device consists of a platform 15 having downwardlyl extending feet 16 at the' marginal edge there-1 of, saidplatform being also provided'with radially extending arms -17 having feet V18 at their outer extremities, thereby l/providing an extended support possessing greatr strength and rigidity but of lightweight. j 'Mounted onthe upper faces of the arms 17 near their outer ends arev boxes 19y in l which anti-friction wheels. 20 arevsupported for rotation.
A `circular housing 21 having an upthe platform 15 where it is secured by means of bolts 23 passing through a flange 24 of said housing. rIhe housing 21 contains a disk 25 having an upwardly extending sleeve 26 that extends through the bearing sleeve 22 and which receves'a tubular axial shaftl 27, the latter being connected with the sleeve 26 by a set screw 28 or other suitable fastening device. The shaft 27 lwill thus be supported in an upright position and in such a manner as to be capable of rotating within the bearing sleeve 22 extending from the housing 21. f
The anti-friction rollers 20 afford a partiai support for a revolving platform 29 having a circular` track 30 that engages the rollers. Saidplatform also has an upwardly extending sleeve`31 anged at its lower end and secured" bymeans of bolts or screws 31', ,said sleeve being arranged to exteriorly engage the bearing sleeve 22, and said sleeve 31 being provided with an 4offset32 that engages the top edge of the bearing sleeve, thereby giving additional support to the revolving platform. The
.upper end portion of the sleeve 31 has a set vscrew 33 engaging the sleeve 26 through ,which the shaft 27 extends, thus enabling the sleeve, 26 carrying the shaft and the sleeve 31 carrying the revolving platform .29 to rotate in unison.
Fixed on the shaft 27 by fastening means such as set `screws 34 is a ,slidable collar 35` which may be secured 'at any desired vadjustment.- 'Ihe collar 35 is provided with lugs or ears 3 6 for .the passage of pivot .the number thereof may be' varied, Each arm A is provided at-its outer end with a y cross bar 3.8, producing a substantially -T-shaped structure, and each of the arms A is-provided withlaterally extending lugs 3 9 with .which the bag holding supporting members 40, 41 are pivotally connected-by rivets. or pins 42. The supporting members 40fand 41 are in the main yof like or similar construction, each having at its outer end a bag engaging curved or hook-shaped poi tion 43 which may be'equipped withblunt bag engaginghooks 44, the saine being secured by means of screws or rivets 44', as best seen in Fig. 1. One of the supporting members 40 -1 has been shown as being ca pable ofbeing adjustably connected 'with been lled, the filled-bag being moved to a `the arm or cross bar 38 by means of a pin or boltl 45engaging one of a plurality of apertures 46; the other arm 41 has ,a portion which is beveled, as best seen at 47 in Fig. 5, said beveled portion being engaged by a toothed yoke member 48 which is pivotally mounted on the cross bar 38 by a pinl 49 and which has a handle 50 whereby it may be manipulated. At the left side of Fig. 2 the toothed yoke member has been shown swung back toa non-engaging position with respect to the support ing member 41.
t will be readily seen that by the simple construction shown and described, a bag, indicated at l13,@ may be securely held by the supporting members 40, 41 with its mouth open to\ receive grain or other material. The bag holder as shown in the drawings is adapted to support four such bags, thus enabling an empty bag to be quickly swung into receiving position as soon as a bag has position where it may be conveniently disengaged from the supporting member and tied or sewed, as may be preferred, to secure its contents.
A second collar 51 which is adjustably mounted on the shaft 27 above the .collar 35 by means of a set screw 52 is provided with radially extending arms 53 corresponding in number to the T-shaped arms A. Con-' nected with each arm 53 by means of fastening members 54, 54 is the'casing ofy a spring scale 55 or other convenient weighing apparatus having a spring supported rod or i slide 55 provided with a weight, supporting hook 56 which is connected by links 51 with eyes 58 on the T-shaped arms A. One of the fastening members, 54', consists of a screw that extends through the casing 55 in 4engagement with the slide 55, which latter may thereby be secured when desired. By this simple appliance it will be evident that the amount of load placed in the bags may. be 1 indicated on the. scales, thus'enabling a determined quantity to be placed in each bag or enabling theA weight of the contents of each bag to be ascertained without subsequent weighing. It will also be seen that the slides of the scales may be secured against movement when desired. The bags when filled may' be partially supported on the revolving platform 2,9. 'Even if it is not desired to ascertain the weight of material placed in each bag, the spring support afforded by the scales is important to permit the gradual sagging of the bags as they are being filled, thereby avoiding excessive strain on the supporting members 40, 41 and also avoiding undue wear and tear on the .bags that are being filled with grain o r other material.
Having thus described the invention, what is claimed as new, is:-
1. In'a device of the class described, an upright shaft supported for-rotation, a collar xed adjustably on the shaft, T-shaped arms pivotally connected with the collar, said arms including cross bars at their outer ends, vbag 'holding elements pivoted on the arms, a second collar fixedadjustably on the shaft above the first mentioned collar and having radially extending arms, casings connected with said arms, springs within the casings, yhook members supported by the springs, and links connecting the hook mem* berswith the arms connected pivotally with the first. mentioned collar.
2. In a device of the class described, an upright shaft supported for rotation, a collar fixed adjustably on the shaft, T-shaped arms pivotally connected with the collar, saidl arms including cross bars at their outer ends, bag holding elements pivoted on the arms, a second collar fixed adjustably onthe shaft above the first mentioned collar and having radially extending arms, casings connected with said arms, springs within the casings, hook members supported by the springs, and links connecting the hook members with the arms connected pivotally with the 'first lmentioned collar; in combination with a platform connected with the upright shaft and revoluble therewith.
3. In a device of the class described, an upright shaft supported for rotation, a collar fixed adjustably on said shaft, an arm pivotally connected with said collar, said arm having a cross bar at its outer end, bag holding elements pivotally connected with the arm, a bolt or pin connecting one of the elements adjustably with the cross bar, and a ratchet member pivoted on the arm and adapted to engage the other bag holding element. l
In testimony whereof I aix my signature.
