“PUL-SYN-ETIC” IMPULSE MOVEMENTS.

As Fig. C9 are manufactured and standardised in three distinct sizes, viz:-

“S” TYPE.
Standard locked Movement built up on brass base for Clocks having glazed (protected) dials for all sizes up to approximately 24-in. diameter.

“B” TYPE.
Double locked standard Movement, built up on brass base, and of more robust construction than “S” Type, for glazed (protected) dials, up to approximately 36-in, diameter.

“W” TYPE.
Powerful double locked Movement, built up on metal base, suitable for large Turret Dials, which are arranged behind glass, or, for slightly less large Clocks with exposed hands.

“SILENT” TYPE.
See below-Fig. CI07/A.
The ” S ” Type Movement is the size which we fit with Contacts for ringing bells, or operating Hooters at pre-arranged times, and contacts for other purposes. (See Illustration on page 33),

Each Movement of Types “S “and “B “consists of heavy wrought brass plate, machined, finished and lacquered ; accurate machine-cut ratchet wheel with 120 teeth ; pawls of steel, hardened and tempered ; balanced aluminium hands running on bridged motion work ; highly efficient electro-magnet. All the moving parts are designed to resist wear, the driving and backstop pawls being of stainless steel to avoid rust. The design of the pawls and stops is such that It is absolutely impossible for them to advance the ratchet wheel more than one tooth at each impulse. The armature of the impelling magnet is designed to operate with a contact of exceptionally short duration, and with a very weak current, one cell only being required for every two 12-ln, dials in a circuit.

In the ” B” Type Movement, the motion work Is constructed to carry larger but light hands.

For larger Clocks with hands exposed to the weather, there Is.nothing equal to a “Waiting-Train ” Movement. (See Book 5, Section 2). Where silence is required, see below.

It is understood by some, quite Incorrectly, that a “click” or “thump” every half-minute is Inseparable from electric Impulse clocks. This Is not so, with the “Pul-syn-etic” System. Most “Pul-syn-etic” Impulse Clocks can be supplied fitted with Inaudible movements, which cannot be heard even during the quietness of the night, For Hotel Bedrooms, Private Offices, etc., where a half-minute “click” would be objectionable, they claim consideration.

The “PUL-SYN-ETIC” Silent Movement does not depend upon a spring suspension or padded case for silence, The special action Is such that the usual percussion or knock is absent, and therefore, does not have to be absorbed or masked, The Movement need not be nursed into position or humoured Into keeping in step with its fellows, it takes practically the same energy to operate it, and Is as permanently reliable as an ordinary Impulse Movement.

The “PUL-SYN-ETIC” Silent Movement is manufactured in quantities and fitted Into all ordinary cases, Wall or Mantel,.up to 24-in. In diameter-glazed fronts, and the cost permits Its general use.

Hotel Bedrooms can be fitted with the Silent impulseClock, giving the Guests the advantage of true time without fear or annoyance to the most nervous occupants, many objecting to even the tick of a watch.

A mechanism so inaudible has never been available in quantity until the introduction of this “Pul-syn-etic” Silent Movement, and It commands special consideration.
