THOMAS A. EDISON, OF LLEWELLY N PARK, NEW JERSEY, ASSIGNOR TO THE EDISON Pl-IONOGRAPH COMPANY, OF NEW JERSEY.
MACHINE FOR MAKENG PHONOGRAM-BLANKS.
SPECIFICATION forming part of Letters Patent No. 393,464, dated November 27, 1888.
Application-filed May 7,1888. Serial No. 273,040. (No model.)
To all whom it may concern:
-Be it known that I, THOMAS A. EDISON, a citizen of the United States, residing at Llew ellyn Park, in the county of Essex and State of New Jersey, have invented a certain new and useful Improvement in Machines for Making Phonogram-Blanks, (Case No. 770,) of which the following is a specitication.
As has been made known by my prior apro plicatious for patents the phonogram-blank which I prefer to employ is one made entirely of wax or a wax composition in the form of a cylinder having a cylindrical outer-surface and a tapering bore. In finishing the outer sur- 1 5 faces of these blanks l have found that the cutting of the wax with ordinary tools at ordinary temperatures is objectionable.
In an application for patent of even date herewith (Oase' No. 768, Serial No. 273,078)
I have described a method of finishing the wax surfaces of phonogram-blanks, consisting in cutting such surfaces with heated knives or cutters. Y
The object of my present invention is to provide a suitable machine for this purpose.
In the accompanying drawings, forming a part hereof, Figure 1 is an end view of the machine. Fig. 2 is aside elevation looking in the direction of arrow 1 in Fig. l, and Fig.
3 is a. section'of the heating-box on line x as, looking in the direction of arrow 2 in Fig. 1.
A is a suitable base or table carrying bearings on which the shaft B is mounted. Outside of the bearings is the mandrel O, and be- 3 5 tween'the bearings the pulley a, by which the mandrel is rotated. This mandrel Ois adapted to receive the cylindrical phonogranrbla-nk' made of wax or having await-coated external surface. Parallel with the mandrel O'is an 0 ranged a box, D, having trunnions b c, which are mounted in hearings in suitable supports rising from the base A, and is adapted to be swung on such trunnions. Upon the upper forward edge of the box D is secured a cutting- 5 knife, E, which, by the swinging of the boxD on its trunnions, is moved toward and away from the mandrel C. The box D is provided with inlet and outlet pipe connect-ions F G, made flexible to permit of the movement of the box D,and having stop-cocks, as shown. These pipes supply a heating medium-such as steam, hot water, or hot air-to the box D, such medium being caused to have a circuitous route through the box I) by means of the partitions d, as shown in Fig. 3. To the trunnion c of the box D is secured a rearwardlyprojecting arm H,'whi::h is pressed upwardly by a spring, I, and is limited in its downward movement by an adjustablestop, J, which may be a screw passing upwardly through the base A. Bearing on the upper side of the arm H, at its outer end, is a cam, K, carried by the end of a hand-lever, L, which is pivoted to a bracket, e, rising from the base A. The earn K limits the upward movement of the arm H. and hence limits the extent of withdrawal of the knife E from the mandrel C, which withdrawal is effected by the upward pressure of the spring I, while the adjustable stop J,'by limiting the downward movement of the arm H, also limits the forward movement of the knife E. It will thus be seen that by adj ust-' ing the stop 3' the precise position to which the knife E will be advanced by turning the cam K by means of the handle L will be fixed.
The heating medium being supplied to the'box- D and rcgulated'by the stop-cocks, such box will be brought to the desired temperature, which is slightly below the melting-point of thewaxor waxcomposition. The phon'ogramblank will be pushed upon the mandrel Qand such mandrel will be started revolving, when by a quick movement of the handle L the heated knife E will be thrown forward against the wax surfaceof the phonogram-blank, and the blank will be turned true by the combined action of heating and cutting, when the blank will be removed'from the mandreland another substituted in its place.
The machine may be provided with a swingo ing knife,M,for cutting the phon0gia1n-blanks into two or more lengths; but such a knife is not an essential feature of the machine.
What I claim as my invention isv 1. The combination, with a revolving mandrel, of aheated cutting-tool for turning off the external surface of a wax phonogram-blank mounted on such mandrel, substantially as set forth.
2.'The combination, with a turning manmo (1[Gl,OfZlll1OViIlg-b0i having pipe connections for supplying it with a heating1nedium,a knife mounted upon such box,and a handle for moving the box toward and away from the man- 5 drel, substantially as set forth.
'3. The combination, with a turning inandrel, of a pivoted box, pipe-connections for supplying a heating medium to said box, a cutting-knife mounted upon the box, and ahandle toward and away from the mandrel, substntn tially as set forth.
t. The combination, with a revolving mandrel, of a pivoted box, pipe'connections for supplying aheating medium to thebox,aknife mounted'on the box, a handle swinging said box so as to move the knife toward the mandrel,and a spring turning the boxin the 0pp0 site direction to move the knife away from the mandrel, substantially as set forth.
for turning said box so as to move the knife 5. The combination, with a turning mandrel,of a pivoted box carrying a knife and having pipe-connections for supplying it with a heating medium,-a handle swinging the box, so as to move the knife toward the mandrel, and an adjustable stop limiting the forward movement of the knife, substantially as set forth.
6. The combination, with a turning man- 'drel, O, of a swinging box, D, carrying aknife,
E, and having pipe-connections F G, the arm 11, the cam K, turned by handle L, the spring I, and the adjustable stop J, substantially as set forth.
This specification signed and witnessed this 28th day of April, 1888.
