ISAAC F. BURTON, OF PHILADELPHIA, PENNSYLVANIA.

FRICTION-SUPPORT FOB, LIDS.

Specification of Letters Patent.

Patented June 15, 1920.

Application filed December 4, 1919. Serial No. 342,3d5.

To all whom it may concern:

Be it known that I, ISAAC F. BURTON, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Friction-Supports for Lids, of which the following is a specification;

One object of my invention is to provide an improved friction support for lids which will be particularly adapted for use in connection with the hinged lids or covers on talking machine cabinets and will be so constructed that it will hold the lid or cover in various pivotal positions into which it is manually moved.

Another object is to so construct my invention that the supporting bar is free to move in various paths relatively to its friction engaging means so that various parts of said engaging means will be presented to said bar and thereby prevent the .bar from wearing a groove in the friction engaging means which would soon cause the friction engaging means to lose its grip upon said bar.

Another object is to make my invention of a simple and durable construction and i so that the amount of friction exerted between said friction engaging means and said bar can be readily adjusted.

A further object is to so construct my invention that it can be easily and quickly made and placed in position.

These objects, and other advantageous ends which will be described hereinafter, l attain in the following manner, reference being had to the accompanying drawings in which Figure 1 is a sectional elevation taken on the line 1-1 of Fig. 2 showing my invention applied to a talking machine cabinet and illustrating a lid or cover in a closed position,

F ig. 2 is a sectional elevation taken on the line 2'2 of Fig. 1, drawn on a smaller 'scale and illustrating in full line position the lid in a raised position and in dot-anddash line position, the lid closed,

Figs. 3 and if: respectively represent face and edge views of the lid supporting bar shown in Figs. 1 and 2,

Fig. 5 is a face view of one of two friction ererting pads which form a part of my mventlon,

Figs. 6 and 7 are face views of two side plates which form a part of my invention and between which the friction pads are adapted to be positioned,

Fig. 8 is a side view of a hanger bracket which is preferably employed, and

Fig. 9 is a top plan view of a slotted facing plate which 1 preferably use.

Referring to the drawings, 10 represents a structure illustrated in the form of the body portion of a talking machine cabinet and 11 represents a lid which is pivotally connected to the body portion 10 by hinges 12. A partition or ledge 13 is included in the body portion 10 and this partition has a slot li formed therein and the slot 14: can be made comparatively wide and covered by a facing plate 15 which has a comparatively narrow slot 16 therein. A. hanger 17, which is preferably made of a piece of flat strip metal bent into the form shown in Fig. 8, has its upper extensions 18 secured to the partition 13 by means of screw bolts 19; said screw bolts passing through the partition and also serving to hold the facing plate in position, as clearly shown in Fig. 2.

The bottom of the hanger 17 has a slot 20, and a lid supporting bar 21 extends upwardly through the slot 20 and through the slots 1% and 16 and is pivotally connected at 22 to a fixture 23 which is screwed to the inner surface of the lid 11. Two friction pads 24; and 25 fit the space within the hanger l7 and are located one adjacent each wide face of the bar 21. These friction pads may be made of leather or other suitable material and as illustrated are of rectangular form as shown in Figs. 2 and 5. Two plates 26 and 27 are positioned adjacent the respective outer faces of the pads 24 and 25; the plate 26 having two separated round holes 28 while the plate 27 has two angular holes 29 which are also spaced apart as shown in Fig. 6. The plates 26 and 27 are preferably made smaller than the pads 24 and 25 so as not to touch the sides or the bottom of the hanger 17 when placed in the position shown in Figs. 1 and 2.

Each of the pads 24 and 25 has two holes 30 which are spaced apart and two clamping bolts 31 are adapted to be inserted through the holes 28, 29 and 30 of the above mentioned plates and pads, as clearly illustrated, said clamping plates having angular portions 32 adjacent their heads 33 which fit within the angular holes 29 of the plate 27 so as to prevent rotation of said clamping bolts.

Thumb nuts 34 are fitted on the clamping bolts 31 and coiled springs 35 are interposed between the thumb nuts 34; and the plate 26. The clamping bolts 31 are thus spaced a comparatively great distance apart or in other words are spaced apart a distance which is greater than the width of the supporting bar 21. The lower end of the supporting bar 21 has a pin 36 projecting therefrom and adapted to engage the lower surface of the bottom of the hanger 17 to limit the upward pivotal movement of the lid 11 on its hinge 12. The amount of friction exerted by the pads 24: and 25 against the supporting bar 21 can be varied by adjusting the thumb nuts which are located in a convenient position and this friction can be maintained at all times sufficient to hold the lid in any of its pivotal positions into which it is manually raised. For example, if it is desired to only partly raise the lid, the friction will be suflicient to hold the lid in its partly open position. If the lid to be supported is extremely heavy, the thumb nuts 3 1 can be turned inwardly to increase the friction and in this manner the device can be adjusted to suit lids of various weights. As is obvious from the full and dot-and-dash line positions of Fig. 2, the supporting bar 21 is free to swing, during its raising or lowering positions, between the clamping bolts 31. In view of this construction the bar 21 will seldom move twice in the same path and therefore will not act to wear grooves in the adjacent faces of the friction )ads; 1 By making the plates 26 and 27 slightly smaller than the interior of the hanger 17, the plateswill have no metallic contact with the hanger and the device will practically be noiseless in its operation.

By the use of my invention not only can the lid be held in any pivotal position as above described but by means of the 0011- struction and arrangement of the parts, said parts can be adjusted so that the lid will stay all the way open and when the user wishes to close the lid he can do so by giving it a slight push downward and it will then fall quietly to its closed position due to its own weight.

While I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but

consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A device of the character described including a supporting bar; friction producing means having a surface for engagement with and of greater width than said bar whereby the latter can move unobstructedly in the direction of its width and length relatively to said surface of the friction means; and means for holding said surface of the friction means in engagement with said bar; substantially as described.

2. A device of the character described including a supporting bar; a friction producing pad having a surface for engagement with and of greater width than said bar; means forming a support for said friction pad and including a slot through which said bar extends, said slot being of a width greater than the width of the bar whereby the bar can move unobstructedly in the direction of its width and length relatively to said surface of the friction means and its support; and means for holding said surface of the friction means in engagement with said bar, said holding means including parts located at opposite sides of the path of movement of said supporting bar; substantially as described.

3. A device of the character described including a supporting bar; a supporting hanger having a slot in its bottom; friction pads mounted within said hanger and located adjacent opposite faces of said bar, said friction pads having surfaces for engagement with the opposite faces of and of greater width than said bar; clamping bolts extending through said friction pads at opposite faces of said bar; adjusting nuts on said bolts; and springs interposed between said nuts and said friction pads for holding said pads in frictional engagement with said bar, said bolts being located a distance apart greater than the width of said bar whereby the latter can move in the direction of its width and length relatively to said friction pads; substantially as described.

1. A device of the character described i11- cluding a supporting bar; a supporting hanger having a slot in its bottom; friction pads mounted within said hanger and located adjacent opposite faces of said bar, said friction pads having surfaces for engagement with the opposite faces of and of greater width than said bar; plates located adjacent opposite faces of said friction pads; clamping bolts extending through said friction pads and plates at opposite sides of said bar; adjusting nuts on said bolts; and springs interposed between said nuts and the adjacent plate for holding said pads in frictional engagement with said bar, said bolts being located a distance apart greater than the width of said bar whereby the latter can move in the direction of its width and length relatively to said friction pads; substantially as described.

5. A device of the character described, including a swingable supporting bar; and friction members in engagement with the opposite face of said bar, at least one of said members being fixed and of greater width than the width of said bar, whereby the bar is free to move between said friction members unobstructedly in the direction of its width and length; substantially as de- 15 scribed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ISAAC F. BURTON.
