r A rronwsr Patented Jan. 9, 1934 UNITED STATES LOOSE-LEAF BINDER APPLIANCE Adolph G. Lotter, Milwaukee, Wis., assignor to Stationers Loose Leaf (30., Milwaukee, Wis., a corporation of Wisconsin Application February 15, 1932. Serial No. 592,959

3 Claims.

This invention relates to certain new and useful improvements in loose leaf binder appliances and refers more particularly to equipment used in connection with machine bookkeeping.

In bookkeeping systems of this character, the sheets are held in a loose leaf binder such as illustrated in Patent No. 1,574,992, dated March 2, 1926, issued to Henry C. Miller, and the data is so placed on each sheet that the edge opposite the binder back form the top of the sheet. Consequently the binder must be placed in a position resting on its back with its covers upright, to permit inspection of the subject matter on the sheets and to facilitate insertion and removal of the sheets during use. I

Heretofore it has been customary to provide brackets securable to the covers of the binder to provide rests for supporting them in their desired open position. These brackets were more or less rigidly secured to the covers and their attachment and removal therefrom was bothersome and often difficult, and as it is desirable to drop the front cover when checking the data on the different sheets, this manner of supporting the covers was objectionable and greatly hindered the operator. 7

With this and other objections to existing types of cover rests for machine bookkeeping ledgers or loose leaf binders in mind, this invention has as one of its objects the provision of a novel supporting stand which is entirely independent of the binder and on which the binder may be quickly placed and removed.

Another object of this invention resides in the provision of a novel stand for loose leaf binders of the character described in which one of the cover supports may be quickly folded down to permit the cover to be lowered.

And a further object of this invention resides in the provision of means for holding the book against tipping when the front cover support is lowered and the greater portion of the weight of the book is to the front.

With the above and other objects in view which will appear as the description proceeds, this invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as come Within the scope of the claims.

In the accompanying drawings, one complete example of the physical embodiment of this invention is illustrated constructed according to the best mode so far devised for the practical application of the principles thereof, and in which:

Figure 1 is a perspective view of a loose leaf binder stand embodying this invention; 9

Figure 2 is a view of the stand in end elevation with a loose leaf binder placed thereon and illus trating in dotted lines the manner in which the support for one of the covers folds down;

Figure 3 is a fragmentary bottom view in perspective of a portion of the stand; and

Figure 4 is a perspective view of a portion of the folding cover support.

Referring now more particularly to the accompanying drawings in which like-numerals indicate like parts throughout the several'views, the numeral 5 represents a base consisting of two

members

6 and 7 secured together at their medial portions and at substantially right angles to each other.

At the end portions of the member 7,which is preferably channel shaped in cross section, and at the ends of the member 6, are supporting feet or pads 8 and 9 respectively. The top surface of the member 6 is covered with fibre or other similar material 10 so'as not to-mar the back 11 of a loose leaf binder placed thereon, as illustrated in Figure 2.

The binder back 11 consists of two complementary sections 12 which carry suitable impaling bars to removably hold a stack of sheets 13 there- 35 in and also have suitable tensioning mechanism, not shown, for drawing the sections together to clamp the sheets therebetween. Inasmuch as the detail construction of the binder forms no part of the invention and may be ascertained by reference to the aforementioned Patent No, 1,5'74,992 issued to Henry C. Miller, it is not shown.

The length of the base member 6 is slightly greater than the overall length of the binder back and the ends thereof are directed upwardly as at 95, 14 and. 15. The upper edge of the end 14 is bent inwardly to form a ledge and the'upper'edge of the end 15 is flared outwardly as at 17. It is thus possible to hook one end of the binder cover under the ledge 16. l

The covers 18 of the binder which are hingedly connected with the binder back are adapted to be supported in an upright partially open position as illustrated in Figure 2 by two supporting

arms

19 and 20 carried by the opposite end portions of the base member 7. The supporting arm 19 comprises a horizontal attaching flange 21 from which the arm proper extends vertically for a short distance as at 22 and then at an incline.

The attaching flange 21 of the arm 19 has a .2 .0

loo

plate 24 fixed thereto to increase its thickness and has a rivet 25 depending from its lower surface with the head of the rivet spaced from the bottom of the attaching flange. A screw 26, the head of which is similar in size to that of the rivet, is threadedly engaged with the attaching flange and both the rivet and screw are engageable with key hole slots 27 formed in the base member '7.

There are three key hole slots 27 in each end portion of the member '7, so that the supporting arm 19 may be attached in either of two positions.

The manner of engaging the rivet and screw 26 in the key hole slots to secure the arm in position is obvious, and after the engagement has been effected, the screw 26 may be drawn tight to lock the arm 19 in position.

The supporting arm 20 is similar to the arm 19 with the exception that it consists of outer and

inner sections

28 and 29 respectively hingedly connected as at 30. The inner section 29 like the supporting arm 19 has an attaching flange 31 which also has a plate 32 fixed to its upper surface and carries a depending rivet 33 and a screw 34 for engagement with the key hole slots 27. The inner section 29 is thus securable to the base in the same manner as the supporting arm 19.

The upstanding portion of the section 29, however, is not vertical, but is inclined at an angle thereto so that when the outer section 28 is in position forming a continuation thereof, it is disposed at its proper angle. A holding sleeve 35 is slidably mounted on the

sections

28 and 29, for movement to and from a position extending across the joint between the inner and outer sections as illustrated in Figure 1 to rigidly hold the outer section in its position forming a continuation of the upstanding flange of the inner section.

When it is desired to lower the front cover of the binder as illustrated in dotted lines in Figure 2, the slidably mounted sleeve is merely raised above the joint between the two sections whereupon the outer section may be dropped as will be readily apparent. To return the sleeve to its normal holding position it is only necessary to elevate the end of the other section, the sleeve falling by gravity to its operative position. As best illustrated in Figure 3, the base memher 7 is reinforced at its end portions adjacent the key hole slots by plates 36 spot welded or otherwise fixed to the undersurface of the base member. These plates have

elongated openings

37 and 38 of sufiicient size to accommodate the heads of the rivets and screws.

From the foregoing description taken in connection with the accompanying drawings, it will be readily apparent to those skilled in the art to which an invention of the character described appertains, that this invention greatly facilitates work on ledgers or loose leaf binders used in machine bookkeeping, and that it entirely eliminates the objectionable necessity for forcibly applying or removing one of the supporting brackets whenever it is desired to lower one of the covers to facilitate inspection of the book contents, and it is also apparent that by reason of the interlocking engagement of the overhanging ledge 16 on the base member 6 with the back of the binder tipping of the binder when the front cover is lowered is entirely avoided.

What I claim as my invention is:

1. A book stand of the character described comprising, a base having an element adapted to receive the back of a book and a member extending transversely of said element, means on said base element adapted for engagement over a portion of the back of the book, and upright supporting arms carried by the transverse base member to support the covers of the book in an inclined partially open position, one of said supporting arms being movable to a lowered position to permit the cover supported thereby to be completely opened, and said engagement of the base carried means with the book back holding the same against tipping when said cover is fully open.

2. A book stand of the character described comprising, a base having a member adapted to receive the back of a book, upright arms for supporting the covers of the book in an inclined partially open position, means connecting said arms with the base, one of said arms being movable to a lowered position to enable the cover supported by it to be moved to substantially a fully open position, and means carried by the back-engaging part of the base and overlying a portion of the book back to hold the book against tipping when said cover is fully open.

3. A book stand of the character described, comprising a base consisting of two crossed members, means at the extremities of said members to afford supporting feet, means on one of said members to engage the back of a book and hold the same against shifting with respect to said base, and upright supporting arms carried by the other of said members at opposite sides of said first named member, one of said supporting arms being rigid and the other supporting arm comprising an inner section rigidly attached to the base member and an outer section hingedly connected to the inner section so as to permit movement thereof to and from an upright position, and a sliding sleeve partially embracing said inner and outer sections adjacent their hinged connection to hold the outer section in an upright position, said sleeve being movable out of engagement with the inner section to enable the outer section to be lowered and being automatically movable to its operative position upon raising of said outer section.
