FPECIFICATION forming part Cf Letters Patent NO. 722,296, dated March 10, 1903.
Application filed October 28, 1901. Serial No. 80,307. (No model.)
To all whom it ntay concern.-
Be it known that I, LOUIS GASSARD, pianomaker, of the city of Toronto, in the county of York,in the Province of Ontario,Oanada,have invented certain new and useful Improvements in Tilting-Table Polishing-Trucks, of which the following is a specification.
My invention relates to improvements in tilting-table polishing-trucks; and the object of the invention is to save time and labor and provide a means for the easy handling and polishing of pianos or other articles by one man, so that they may be placed and held in any position necessary for polishing without any injury to the piano or article as is likely to occur by the laborious means hitherto employed; and itconsists, essentially, of a truck and a frame pivotally supported thereon and a means for holding the table in any desired position, as hereinafter more particularly explained.
Figure l is a perspective view of my tilting-table polishing-truck in position for receiving a piano. Fig. 2 is a similar view showing the tilting table in a horizontal position. Fig. 3 is a similar view showing the tilting table tilted to one side. Fig. 4 is a sectional elevation of my truck, showing the position of the piano upon the tilting table. Fig.5isalongitudinal sectionaldetail through the center of the truck. Fig. (5 is a detail of the rocking board for supporting the table, partly broken away and reversed.
In the drawings like letters of reference indicate corresponding parts in each figure.
A is the body of the truck, comprising the longitudinal pieces a a and cross-pieces a a a a are longitudinal timbers suitably secured to the cross-pieces a a of represents separating-blocks tween the timbers a a (t represents upwardly-projecting portions, forming part of the timbers d a H The body of the truck A is supported upon suitable casters a B is the table comprised of the cross-timbers Z) W.
B is a substantially arc-shaped cross-piece pivotally secured between the upwardly-projecting portions d by the bolt o placed beb represents upwardly-projecting portions, forming part of the cross-piece B.
b is a rod passing through the portions b which have secured at their outer ends the cross-timbers b 11 B represents suitable iron feet secured to the cross-timbers 1) b The cross-timbers b b are connected together by the bars 13 and B The bar 13 is suitably hinged atone end of the timbers b U.
B is a supporting-leg pivotally secured to the cross-piece B by the bolt b O represents dowel-pins fixed in the side timbers b 19 and O and O are longitudinal timbers provided with holes 0, into which the dowel-pins are designed to fit.
0 represents blocks suitably secured to the timbers O and O and designed to hold the piano in position upon the tilting table.
The arc-shaped cross-piece B is provided with a recess 1).
D is a spring secured to the longitudinal timber 0?, having an upturned inner end (1, designed to fit into the recess 6 d and d are downwardly-projecting pins secured in the longitudinal timbers a a E is a lever-bar having holes 2 e 6 is a rod connecting the inner end of the spring D to the lever-bar E, the rod 6 being secured at each end by the nuts 6 and c WV'hen it is desired to place the piano upon the truck, the iron feet are placed in the usual manner beneath the piano, which is then tilted back against the tilting table, so as to bring the blocks 0 Within the frame, as shown in Fig. 4. The tilting table and piano may then be tilted into a horizontal position, in which position it is supported by the leg B In this position the face of the piano may be polished. When it is desired to polish the sides of the piano, the foot of the workman is placed upon the lever-bar E, so as to draw the spring D downwardly, thereby releasing the rocking board B. The tilting table will then be tilted laterally until one of the longitudinal oars B rests upon the body of the truck. When that side is polished, it may be tilted in the opposite direction, so as to bring the other side into a convenient position for polishing.
ICO
In the old method of handling pianos they had to be placed on trestles and handled by several men, which necessitated the back of the piano being left unpolished, this surface always coming in contact with the trestles, thereby becoming injured. By my method the piano is held stationary on the table during the whole operation, and therefore does not become injured in the handling, as the table only is handled.
It will be seen from this description the pianos may be very easily handled and at the same time a great amount of time and labor saved and all danger of their becoming scratched or otherwise marred during handling avoided.
What I claim as my invention is 1. In combination with a stationary baseor truck having a central pivot, a frame composed of longitudinal and cross bars connected together and a connection between the said frames and the central pivot, said connection including a pivot which allows the said frame to tilt in a direction at right angles to that permitted by the central pivot, substantially as described.
2. In combination with the truck, a frame comprising cross-timbers, longitudinal timbers at right angles to the cross-timbers, said cross-timbers having the feet B and the iongitudinal timbers having the holdfast-blocks and a pivotal connection between the frame and the truck to allow the frame to tilt either in the direction of the cross-timbers or of the longitudinal timbers, substantially as described.
3. In combination, the truck, a frame, a pivotal connection between the frame and the truck, allowing the same to tilt in two directions, a pivoted supporting-leg connected with the frame and a spring-detent for holding the frame in position, substantially as described.
4. In combination, the truck, the timbers a a an arc-shaped piece B pivoted between said timbers, a detent for engaging said arcshaped piece and a frame pivotally connected to said arc-shaped piece to tilt in a direction at right angles to that in which the arc-shaped piece may be tilted,substantially as described.
5. In a tilting-table truck, the combination with the frame or body of the truck, of a rocking bar pivotally supported on said truck provided with an arc-shaped lower portion having a recess formed therein, a spring-bar secured t0 the base of the truck provided with an upturned end designed to enter said recess, a foot-lever pivotally secured at its outer end to the base of the truck and intermediately connected to the inner end of the springbar, and a table secured to said rocking bar as and for the purpose specified.
LOUIS GASSARD.
