Corner Indices

Corner Indices were a major innovation in playing card production.

1864 Dougherty Hart Muir & Moodie Saladee Woolley & Co Dexter Squeezers Triplicate History Indices Innovation Patent Add to Collection

A patent was issued on February 9, 1864 to Cyrus W. Saladee of Paducah, Kentucky, under patent number 41,587. It is believed to be the first American deck with corner indices.

“My invention consists in combining a number or letter with an emblem - such as a heart, spade, club or diamond - so that upon seeing the emblem, which may be in a corner, the denomination of the card is at once understood.”

This idea revolutionized American card manufacture by enabling players to fan the cards to view only the corner of each card, sufficient to see the indices. This was soon followed by Andrew Dougherty’s patent for “Triplicates” and other novel systems of index types which were adopted by other manufacturers until, over time, they became the new norm.

Triplicates

Andrew Dougherty first secured a patent for “Triplicates” in 1875, a novel type of indices with a miniature card in the top left-hand corner (and bottom right). These kept Dougherty at the forefront of innovation. There are several variations in the size and design of the “Triplicate” indices, with the smallest being the earliest. Dougherty's “Triplicates” have a specially designed Ace of Spades with a spread of cards inside the central Spade symbol demonstrating the innovation.

In 1876, the year after Dougherty, Robert Chanony of France patented the same idea. Patent number US182166

“The object of my invention is to improve playing-cards by rendering it possible for players to distinguish the cards in their hands without exposing them ... and this I accomplish by combining with each card one or more miniature representations thereof, as shown in the accompanying drawing.”


Willis playing cards, c.1875

Above: following the lead of American manufacturers such as Dougherty and New York Consolidated Card Company, Willis & Co. introduced novel types of miniature corner indices to facilitate fanning or 'squeezing' the cards during the mid-1880s. The miniature 'triplicate' cards in the corners were apparently registered, and are ¾ or full-length figures. Interestingly the mini court indices are full length courts but Willis appeared never to manufacture full length court cards.


Indicators

Dougherty’s innovations include adding Best Bowers, Jokers, rounded corners and introducing various novel types of indices to his cards. In 1883 he was granted a patent for numbered indices, or “Indicators”, printed outside the border, along with the earlier form of “Triplicates”. It also has small breaks in the borders, as in Spanish cards, (see earlier patent for this) and these innovations helped players distinguish cards by only peeping at the corners.

These “Indicators”, printed outside the border, soon became standard.

Dougherty's “Ivorette No.70” deck has the “Indicator” Ace of Spades and a Jolly Joker

Above: Dougherty's “Ivorette No.70” deck has the “Indicator” Ace of Spades and a Jolly Joker. The Ace of Spades mentions two patents, the earlier date being for the first “Triplicate” format and the second date being for the addition of the indicator number. It was the last of the Triplicate series and incorporated the first use of numbered indices. The small margin breaks in the miniature playing cards differentiate the suits. It only ran for a year or less and was followed in 1894 by Indicators No.50. Image courtesy Rod Starling.

Many brands were issued featuring these new “Indicators”. The main distinguishing feature was the box. Brands include “Ivorette”, “Tudor”, “Tandem”, “Mogul”, “Sunset” etc.

Regarding Dougherty's “Indicator” indices that were patented in 1883, that would have been just six years after NYCCC obtained its own patent for “Squeezers”, which are more or less the same idea. It is difficult to understand what difference there was between NYCCC's “Squeezers” and Dougherty's “Indicators” that would warrant each company being granted patent rights at about the same time.

Similar new ideas were being introduced or imitated simultaneously by other manufacturers both in USA and elsewhere, with various different patented brand names, such as “Squeezers”, “Dexters”, “Eureka”, etc. so that the corner indices we now take for granted were born from these competing innovations.


The Muir & Moodie Photography Studio (1898-1916) published post cards and other photographic items documenting events in New Zealand daily life. The playing cards shown here, described on the extra card as the Greatest Novelty of the Century, feature “Triplicate” indices and corner pip arrangements on the numeral cards. The cards were printed in Bavaria (Germany) for export to New Zealand where they were sold.

Dexters

The "Dexter indexes" are interesting in that the suit-signs in the corners bear a number in white upon them; the 2s and 3s have had their pips moved to accomodate this scheme. The corners of the Aces bear the outline of the respective suit, in which is the word ‘ace’. There is no marking of any sort on the Ace of Spades. The suit signs on the courts bear the letters ‘Kg’ on a King, ‘Qn’ on a Queen, and a ‘Kn’ (shorthand for "Knave") on a Jack. The original Dexter indices placed inside the corner pips had several variants: ‘Kn’ or ‘J’ for Jack; two arrangements of Aces, twos and threes; and ‘1’ or ‘ace’ on the Aces. This type of index was introduced in around 1878 and continued until c.1890. There are no jokers in this edition.

Eurekas

Packs with corner indices, along with rounded corners, had been introduced by Woolley & Co as a novelty around 1878-79 and were sold at that time for one shilling per pack. There were two versions: one with diagonal twos and threes, the other with vertical twos and threes, with small corner indices as on the ace of spades. Sometimes the AS doesn’t have an index. Both Woolley and De La Rue retained the original names for their indices after they had changed to ordinary ones. Palace Gold Dexter Moguls were still being advertised in 1931.

Hand-drawn indices

Right: during the period c.1870-1890 indices were being introduced on playing cards. Packs are sometimes found with hand-written indices where players have improvised in interesting ways, providing documentary evidence of the days when corner indices were still in their infancy.
