Howard Miller Hourglass IV Grandfather Clock 615170

Partially verified

The Howard Miller Hourglass IV is a floor clock featuring a tubular metal frame finished in aged bronze. The design incorporates a motorized geared dial suspended within the upper frame, finished in dark aged bronze, and a centrally positioned 28-inch tall hourglass. The hourglass contains a sand timer of approximately one hour, designed for manual rotation and positioning via a handwheel. The clock's dial is illuminated by LED strip lighting controlled by a touch dimmer pad located on the upper right-hand side of the head, providing four brightness levels. The time-only, quartz battery-operated movement requires one AA battery and one D battery. The base includes a metal shelf for display purposes and four adjustable floor levelers for stability. The overall dimensions of the floor clock are 74 inches in height by 18.5 inches in width and 14.5 inches in depth.

Object description

Structure and Design

The Howard Miller Hourglass IV (model 615170) is a floor clock constructed from a tubular metal frame finished in aged bronze. The frame is accented with dark aged bronze elements located at the head, the base, and the hourglass assembly. The overall design occupies a vertical footprint of 74 inches in height, 18.5 inches in width, and 14.5 inches in depth.

A prominent feature of the clock is the 28-inch tall hourglass, which sits in the middle of the structural frame. This sand timer, designed to measure approximately one hour, can be manually rotated and adjusted using an integrated handwheel. The base of the unit includes a metal shelf suitable for the placement of objects, and the unit is stabilized by four adjustable floor levelers.

Evidence for this section
  • “tubular metal frame finished in aged bronze with a head, hourglass, and base finished in dark aged bronze.”
  • “A 28" long hourglass in the middle of the case features a sand timer of approximately one hour which can be rotated and positioned by hand.”
  • “Four adjustable floor levelers provide stability.”

Dial and Illumination

The clock head contains a motorized geared dial protected by convex glass. The bezel and the dial are finished in dark aged bronze, while the motorized gears exhibit an aged bronze finish. The time display includes hour markers, Arabic numerals, and hour and minute hands, all rendered in aged gold.

To improve visibility, an LED strip light is positioned behind the dial. The light intensity is adjustable through a touch dimmer pad situated on the upper right side of the clock head, offering four distinct settings: low, medium, high, and off.

Evidence for this section
  • “The motorized geared dial is suspended on top of a tubular metal frame”
  • “The bezel and dial are finished in dark aged bronze”
  • “The dial is lit with LED strip lighting that is located behind the dial.”

Movement and Operation

The timepiece is powered by a quartz, battery-operated movement intended for time-only display.

The mechanical complexity is centered on the visual appearance of the motorized gears, which operate in conjunction with the quartz mechanism. Maintenance is limited to standard battery replacement, as specified by the requirements for the two different battery types used within the unit.

Evidence for this section
  • “Time only, quartz battery-operated movement requires one AA-sized battery and one D-sized battery”
  • “motorized geared dial”
  • “Condition: Factory new”

Open research questions

  • What is the material composition of the gears and the tubular frame?
  • Are the motorized gears synchronized with the quartz movement or independent?
