The talking machine world (Jan-June 1918)

58 THE TALKING MACHINE WORLD March 15, 1918 I THREE YEARS PROGRESS (a The last report of our Board of Directors to our Stockholders states that the increase of sales of © "HOFFAY" products during 1917 was 1,808 per cent over those in 1916. 1 m> WHY? *i) Because we manufacture the perfect instrument. Because we manufacture the reproducer which has led the World for the last four %i% years — the "RESURRECTONE," with its exclusive "Tuning-fork." Because we have the next best reproducer — the "Half-fork-tone." {(% Because we manufacture the unique "Air-tight" mechanism from the Reproducer to the grill of the cabinet, which preserves the beauty IL of the "HOFFAY" tone. /A If to a "wind" instrument you add or change the position of a hole or "key," the tone changes. W If a "string" instrument gets cracked the tone is lost. yf If a "singer" loses a front tooth his tone is lost. %lj If a "cigar" gets broken the flavor is gone. ff% The same applies to a talking machine — that is why the "HOFFAY," although playing Victor and Edison types of records, is "Air-tight." yj[ Spring (1) supports full weight of Tone-arm (2) and is insulated by CXI felt padding A. Part of weight of Reproducer (18) is allowed to bear on Victor records, and this weight is just what it should be for this type of CXj record. Edison records require more weight than Victors and this is automatically given by the "HOFFAY" because Edison records are thicker, and the principle of this form of spring is that the thicker the record, the more weight there is upon it. Tone-arm (2) is supported by revolving base (3) at pivots (4). The Tone-arm is straight, there being no curves or joints hindering the sounds. Joint (13) is cemented and consequently air-tight. Stationary base (5) carries balls (6) upon which revolving base (3) turns around for the horizontal movement of Tone-arm. Revolving base (3) is held by balls (7), the adjustment of which is made by ring (8), the weight of which is taken up by washer (9), leaving the balls free; thus a remarkable anti-friction mounting is obtained. Flange (10) suspending from revolving base (3) goes into groove (11) in stationary base (5) without contacting with said groove, which is filled with lubricating material, and is continually lubricated mainly by capillarity; thus a permanent air-tight and anti-friction joint being provided. Balls (6) and (7) are oiled through space (12) and as the end of revolving base touching the balls is sunk into lubricating material, the airtight mechanism described above is reinforced. Space (14) between Tone-arm (2) and revolving base (3) permits the up and down movement of Tone-arm. This space is absolutely closed by means of flexible washer (15) supported by ring (16) and by end (16) of Tone-arm, where it is fastened. This washer (15) leaves Tone-arm absolutely free to move, and is guaranteed to last for several years — also, it may easily be replaced. An ideal flexible and vertical air-tight device is exclusively provided by the "HOFFAY." Equality of distance between stylus (20) and vertical axis (21) of Tone-arm (2) when Reproducer (18) is in position to play Edison records as shown in photograph 2, or in position to play Victor records shown in photograph 1, is essential for good reproduction of sound and for lengthening the life of records. This is afforded by the "HOFFAY" automatically, no screws to fasten nor detaching of Reproducer being necessary. To obtain good tone it is essential that the diaphragm corresponds in line with the vertical axis of horizontal movement of Tone-arm. Photograph 3 shows a dotted line from axis (21) of Tone-arm (2) to diaphragm (25) inside of Reproducer (18), thus demonstrating that this essential requirement is fulfilled. It is equally essential that stylus (20) be in line with axis (21) when playing Edison records and in photograph 5 will be seen that this requirement is also fulfilled. Perfect air-tightness is given by padding (26) in Tone-arm (2), and by padding (27) in Reproducer (18). See photograph 3. These paddings contact with flat surfaces (29) and (30) of elbow (31), respectively, when playing Victor records. The two paddings contact with one another when playing Edison records. To play Edison records loosen up screw (40) and press clip (35), which releases elbow (31). This elbow swings out of the way on steel pivots (32) supported by steel braces (33), thus permitting Reproducer (18) to be swung on steel pivots (34) into the Edison position. Spring (17) locks up Reproducer (18) by engaging with the steel screw-head (19), and in this way a fixed position for Edison records is obtained. To change from Edison position (see photograph No. 5) swing Reproducer (18) to position shown in photograph No. 4 and press elbow (31) against Reproducer until plate (36) springs by itself over part (3S) of said elbow. Then tighten up screw (40) so as to hold more firmly Reproducer (18) against elbow (31). In this way a fixed position is furnished by the "HOFFAY" for playing Victor records, and you know it's right because you hear it click. The braced construction is such that nothing but perfection is attained. Either in "fixed" positions which the "HOFFAY" gives (and which prevent mistakes being made by the user of the machine) ; or in proper weights (for playing Victor and Edison records) given automatically by the "HOFFAY"; or in an absolutely air-tight construction (free from rotary joints, which in time loosen up, rattle and permit air to escape); or in an absolutely straight and air-tight Tone-arm; or in the most remarkable anti-friction and air-tight horizontal mounting for the Tone-arm, the "HOFFAY" fills all and every requirement for attaining perfection of sound and for fool-proof operation of the machine by the user. Our new cabinets are beautiful and distinctive, befitting the perfect instrument they enclose.
