Size

Will it fit? Check these sizes against your wall

Measure the wall between whatever bounds it — window trim, a doorway, the corner. Sizes are judged hung (frame included) with 6 in of breathing room, two-thirds the width of the furniture under them, and the center at eye level (57–60 in). Guidance, not a guarantee: the true-size template is the final check.

  • Made to order just for you: printed, finished and packed within 3–5 business days. Your order reaches the printer within minutes and printing can start soon after; once it starts, the order can't be canceled or changed.
  • Free replacement if it arrives damaged, defective or not what you ordered — tell us within 7 days of delivery, with photos. Because each piece is made for you, there are no returns for a change of mind. Full policy
  • No hanging hardware is included. Stretched and framed canvases hang flat on two nails or screws, set level: the wooden bar on the back rests on them, and the free wall template marks the spot. Rolled canvas goes to a framer first.
  • Printed from an archive scan of the original patent drawing (1893). Its paper tone, small spots and marks of age are part of the picture, just as on the original sheet, and colors can look slightly different on your screen.

Materials & finish

Printed on 400 gsm canvas with pigment inks. Stretched canvas and float frame canvas sit on a 1.5 in (38 mm) wooden stretcher; the classic frame holds the canvas on a slimmer 0.75 in (19 mm) stretcher. Rolled canvas ships in a sturdy tube.

The float frame stands 2.1 in (53 mm) off the wall, with a 0.5 in (12 mm) face and a 0.2 in (5 mm) gap around the canvas. The classic frame stands 0.9 in (22 mm) off the wall with a 0.8 in (20 mm) face.

Hanging hardware is not included. Two picture hooks (or screws) rated for the weight, set level, are all it needs; the free true-size wall template marks the spot.

This product is a new print made to order from a restored scan of that patent drawing. It is not an original antique and is not sold as one.

Independently created from a public-domain U.S. patent drawing. Any brand or product name used here identifies the invention shown and belongs to its owner; this print is not affiliated with, endorsed by or sponsored by that owner.

The story of this patent drawing

This is sheet 1 of the drawings for US Patent No. 491,097, titled Dental Chair and granted to A. P. Gould on February 7, 1893. The heading is set in plain typewriter-style capitals, and below it Fig. 1 shows the whole chair in perspective: a headrest on an upright rod, a tall padded back, a padded seat, a footrest with a cross-hatched plate, and a pedestal base standing on curved legs. The lower edge carries the signatures of the witnesses, the inventor and the attorney.

The close-ups show how much is packed into the drawing. Beneath the seat sits a cluster of levers, gears and a toothed rack, each part tagged with small letters such as a, d and h. To one side a round bowl is mounted on a scrolled arm, and a cross-hatched oval pad on a curved stem reaches out nearby. The upholstery is shaded with short strokes, and the headrest clamp, with its knob and handle, is drawn in fine detail.

The busy, intricate drawing on a calm paper ground makes a strong centerpiece. It suits a reception wall, a waiting room, an operatory or a dentist’s private office, and it works at home in a study. It is a natural gift for a dentist, a new graduate or anyone who spends their working day beside a modern version of this chair.

  3. Trimmed the scanner bars and empty margin.
  4. Laid the drawing on a clean aged-paper ground with a fine grain.

About this particular sheet. Drawn from the official grant document for US patent 491,097 (sheet 1 of 4), with the ink lifted onto a clean aged-paper ground.

Questions

What does it show?
Sheet 1 of the drawings for US Patent No. 491,097, titled Dental Chair and granted to A. P. Gould on February 7, 1893. Fig. 1 is a perspective view of the whole chair, with a headrest on an upright rod, a padded back and seat, a footrest and a pedestal base with curved legs, marked with reference letters throughout.
Is this the original patent?
No. It is a new canvas print of the drawing from the official patent document, which is in the public domain. We never sell original documents.
Does it suit a dental office?
Yes. A dental chair is an obvious and good-humored subject for a reception area, a waiting room, an operatory or a private office. It hangs well with the other dental chair patents from 1872 and 1876 and the Tooth Brush Patent (1857) as a set.
How is it made?
It is printed to order for you, in the finish you choose: a float frame canvas, a classic frame canvas, a stretched canvas or a rolled canvas. Both frames come in Black or Antique Gold. The size and finish picker shows which sizes each finish is made in.
Colors vary a little between screens and canvas. The previews are drawn, not photographed, and are a close match to the printed piece.
