WORK-HOLDING STAND.
Specification of Letters Patent.
Patented Apr. 18, 1916.
Application filed July 10, 1914. Serial No. 850,164.
To all whom it may concern:
Be it known that I, CURTIS S. CALHOUN, a citizen of the United States of America, residing at Decatur, in the county of Macon and State of Illinois, have invented certain new and useful Improvements in Work- Holding Stands, of which the following is a specification.
The present invention relates to improvements in work holding stands, and is designed particularly for the purpose of providing a portable stand of this character which is sufliciently small and compact to insure its transportation by a piano tuner in his every day work.
The stand is especially applicable for use in connection with the action of pianos, and the stand is used by piano tuners to support the piano action when regulating or repairing the action.
The invention consists in certain novel combinations and arrangements of parts whereby the piano action may be revolubly supported in position for easy access by the piano tuner, and in certain novel adjusting devices as will hereinafter be more fully described and claimed.
In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles of the invention.
Figure 1 is a perspective view showing the work holding stand, between the two uprights of which the piano action is to be supported. Fig. 2 is an enlarged detail elevation of a portion of one of the uprights, and a supporting bar, partly in section, for convenience of illustration. Fig. 3 is a top plan view of the upper clamp in Fig. 2, showing the supporting bar in cross section. Fig. 4 is a modified form of the device for sup porting a wide upper board.
In the preferred embodiment of my invention, I employ two uprights as 1 and 2. Each of these uprights is provided with legs 3-3, a lower connecting bar 4, and an upper frame 5, including the converging arms 6 6. As shown in Fig. 1 of the drawings, these uprights are each provided with feet 8-8 adapted to rest upon the floor when the uprights are in use, and when desired the lower cross bars 4 may be employed to support a bottom board or shelf 9, Fig. 1.
An upper board or shelf 10 is shown as supported by a pair ofbrackets 11-11.
These brackets 11 are each formed with an end flange 12 and the brackets 11 are detach.- ably secured to the upper frame 5 by means of bolts 16 which are passed through perforations in the bars of frame 5. The shelf 10 may be supported above the piano action, or it may be removed if desired in order to give freer access to the action when working thereon.
Each frame 5 in its upright 1 and 2, is provided with a block or casting 15 which is securely and rigidly fixed in the frame arms 6 by means of bolts 16. This block 15 is formed with a lug or abutment 17 and the lug is perforated to form a continuation of an opening 18 extended through the block 15. This opening 18 is designed to receive a swiveled bolt 19 which is formed with a squared portion 20 within the opening 18 of the block 15 in order to seat the bolt against turning therein. At 21, the bolt 19 is threaded to receive a winged nut 22, and a head 23 on the bolt is shown as countersunk within a socket or recess in the sup porting bar 24. In Fig. 1, a clip 24 is shown as held by the bolt 19, and this clip has a clamping bolt 25' by means of which a piano action may be clamped between the clips 24 and thus revolubly suspended between the uprights. These clips 24 are used on certain styles of piano actions and they are substituted for the bars 24 when so used. The bar 24 is swiveled or revolubly supported in the block 15, and it is clear that it may be revoluble or swung on the bolt 19 if desired, and then by means of the winged nut 22 it may be clamped against the lug 17 of the block in order to hold it in rigid position.
In actual use there are two supporting bars 24 employed, which are designed to directly support the piano action between them, but only one is illustrated in the drawing. At the lower end, the bar 24 is provided with a threaded bolt 25 passed through a perforadrawn together by means of the bolt 31 and the winged nut 32. Thus, the clamping clip 28 maybe employed as shown in Fig. 2, to hold the upper end of the bracket 33 (see Fig. 2) of the supporting action, and the bolt 25 and winged nut 26 may be employed .to clamp and hold the lower end of the bracket 33 as shown in Fig. 2. The clamping clip 28 is adjustable on the supporting bar 24:, and it may be moved vertically thereon to desired position. After the arms 29 and 30 have been secured in position and about the upper end of the bracket 33, by turning the winged nut 32, the arms 29 and 30 are brought together to hold the bracket 33, and at the same time this clamping clip is rigidly secured to the supporting bar 24:, as will be understood.
In Fig. 2, only one arm 24 is illustrated in connection with the upright arms 6 of frame 5, but it will be understood that. these parts and their several devices are duplicated. Thus, when using the supporting bar 24: the lower end of each bracket 33 is placed in position over the bolts 25, and the upper end of each bracket 33 is inserted between the arms 29 and 30 of the clamping clip 28, as in dotted lines, Fig. 2. The winged nut 26 is then turned to clamp each bracket 33, and the winged nut 32 at the upper end of each supporting bar is turned to clamp the clip 28 to the supporting bar, and also to the bracket 33. After the piano action has been firmly secured to the two supporting bars, the winged nuts 22 may be loosened, and then the action and supporting bars may be bodily swung upon the bolts 19 as pivots, to the desired inclination or slant. Then by tightening up the winged nuts 22 the action will be held in adjusted position.
The boards 9 and 10 may be omitted at the discretion of the tuner. They may be used as shelves for supporting the tuners tools, clamps, felt, and other repair material, and the upper board, as before stated, is adjustable so that it may be moved out of the way of the tuner in order to give free access to the piano action.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is
In a work holding stand the combination with an upright supporting member having a bearing, of a bolt passed through said bearing having an intermediate non-circular I portion a threaded end portion and a headed end with a circular portion between the head and the threaded portion, the intermediate portion engaging the bearing, a supporting bar held by the head of the bolt and revoluble on the circular portion and having work holding devices adjustable longitudinally along the bar, and a winged nut on the other end of the bolt for clamping the bar in angularly adjusted position.
In testimony whereof I affix my signature in presence of two witnesses.
