GLUlNG-PRESS.
SPECIFICATION forming part of Letters Patent No. 585,558, dated June 29, 1897. Application filedJ'anuary 29, 1897- Serial No. 621,196. (No model.)
To ctZZ whont it may concern:
Be it known that LALFRED DODGE, a citizen of the United States, residing at Dolgeville, in the county of Herkimer and State of New York, have invented new and useful Improvements in Gluing-Presses, of which the following is a specification.
This invention relates to a machine or apparatus by which felt can be glued to the molding of a piano-hammer; and the invention resides in the novel features of construction set forth in the following specification and claims and illustrated in the annexed drawings, in which Figure 1 is an end elevation of a gluingpress. Fig. 2 is a front elevation of Fig. 1, partly broken away. Fig. 3 is a section of the press, looking toward an end clamp. Fig. 4 is a section of the press, looking toward an intermediate clamp.
A base or support 1 is adapted to receive a holder comprising a base part 2 and sides 3,
flanged, as seen at 4. The holder has slides or compression pieces 5, which can move toward and from the center or channel part of the trough or holder and which can also be fixed by tightening-screws 6.
The piano-hammers each comprise a molding having a stem 7 and a fork 8. In the fork 8 is to be glued the felt 9. As the hammers or moldings for different piano parts, such as bass and treble, are not exactly alike, said moldings when assembled in holder 2 3 have the base-points 10 of their respective forks or tines 8 brought to a level with one another by suitable pieces or strips 11 placed in the holder and of such width as to effect the desired leveling. The full and dotted lines in Fig. 1 respectively indicate bass and treble hammers.
Alongside the strips 11 and the moldingstem 7 are placed pieces 12 and 13, all suitably held in place by clamping-screws 14 in a side of the holder. These screws act against the pieces 12 and 13 or against suitable pieces or steel gibs 15, interposed between the screws and the pieces 12 and 13.
I By using brass for the pieces or strips 11, 12, and 13 it has been found that the wood of the molding 7 8 will not be stained.
Jointed to the holder at or near each end portion, as at 16, is a swinging clamp-carrier 17, shaped like a bail and adapted to swing over the adjacent holder end, and to which carrier 17 at 18 is fulcrumed a lever-handle 19, having an eccentric or cam 20. This carrier 17 has a slide 21, engaged by cam 20 and guided by said carrier or holder 17. This slide 21 has a foot 22, channeled to properly sit on or engage a pressure-piece or wooden strip or strips 23. This strip or strips 23 are properly channeled or forked, as at 24:, to sit on and center the work or the felt 9 in the fork 8.
In addition to the jointed or swingingclampcarriers 17 there are detachable clamp-carriers 25, whose hooked portions 26 are adapted to engage or slide under the holder-flanges 4. As many such carriers as seen fit can be connected to the holder alongside one another. These carriers 25, like the carriers 17, have cam levers or handles 19 20, acting on slides or clamps 21, with channeled 'feet 22, acting on strip or strips 23.
When glue has been introduced between molding-forks 8 and felt 9 and the slides 5 have been pressed against forks 8 and the strip or pressurepiece 23 suitably pressed against the felt by actuating-handles 19 to a proper degree, the parts 8 and 9 will be held or pressed together to secure firm adherence.
The slides 5 are actuated by jaws 27, run toward and from the respective slides by right and left hand screw-threads 28 on rotary shaft 29, actuated in any suitable way. WVhen the jaws 27 have suitably pressed slides 5 against molding-fork 8, said slides can be locked by screws 6. The jaws 27 can then be retracted and the holder, with the hammers compressed by parts 5 and 23, can be put aside until the glue has set and meanwhile a fresh holder placed or slid on the base 1. The operation of gluing felt to hammer moldings can thus continue without interruption.
The individual molding with felt for each hammer might be placed into the holder, but it has been found practicable to introduce strips of molding each long enough for a set of hammersas, for example, a bass set with corresponding strips of felt into the apparatus and after such strips are glued together to saw off the proper thicknesses or sections for forming each hammer. The felt 9, it may be noted, when properly crimped and in proper form, requires no trimming or fitting before being glued to the molding.
While placing moldings into or removing them from the holder or placing strip 23 in position, the clamp-carriers 17 can be swung down or out of the way on pivots 16 and the carriers 25 removed. The carriers 25 are sectional or composed of parts jointed or hinged together, as at 30, Fig/1, so as to be readily clasped to or unclasped from the holder or flanges 4. The set-screws 14 when properly tightened will cause the strips 12 13 15 to pre vent glue getting in between the several strips 1 of molding. When the form with the mold ings has been placed on base 1, glue is applied to the moldings, the felt then inserted, and the strip or strips 23 put in place. The clampholders or carriers 17 and 25 being then brought into Working position, the felt can be forced into the moldings. The pressure or compression slides 5 being brought up against forks S, the moldings and felts will be pressed together. The locking-screws 6 being then tightened and the jaws 27 withdrawn, the holder or form 2 3, with the set of hammers glued and clamped, can be put aside and another one placed in the machine. By having the slides or clamps 21 connected with feet 22 by ball-and-socket joints the feet can readily adapt themselves to required position.
What I claim as new, and desire to secure by Letters Patent, is
1. A holder for gluing-presses, said holder having a flanged top, a bow-shaped clampearrier transversely jointed to an end portion of the holder, and removable clamp-carriers comprising jointed hook shanks or sections adapted to engage the holder-flange and to straddle or extend transversely across over the top of the holder, substantially as described.
2. A gluing-presscomprising a fixed base or support, a holder fixedly seated on the base and having a flanged top, a bow-shaped clampcarrier transversely jointed to an end portion of the holder, removable clamp-carriers comprising jointed hook shanks or sections adapted to engage the holder-flange and to straddle or extend transversely across over the top of the holder, compression-slides movable transversely across the top of the holder, and fixing-screws for said slides, said base having actuating-jaws for the compression-slides, and an oppositely-threaded screw-shaft for actuating the jaws toward and from one another, substantiallyas described.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
ALFRED DOLGE.
