The invention relates to a group table slide particularly to one wherein numerals, indications or illustrations on a tongue or the like movable relatively to an outer part are visible in openings in the outer part so that the purpose or the relation of the numerals or the like relatively to other numerals or the like is immediately or easily ascertainable. Table slides of this character with only a, single tongue are known. In order, however, to solve certain problems, for example, to carry out wage calculations, interest calcula tions and so forth, a plurality of tongues is necessary if the table slide as such is not to acquire a too unpracticalsize. When a number of tongues are used they must be arranged in groups one above the other in a guide sleeve or the like.

In order that the'reading of the numbers is easily possible from each separate tongue, each tongue is provided with one or more apertures O which enable the figures or other indications of tongues located at alower level in the pile to be seen through the openings in the tongues located above them and in the tongue guide. In this manner verymany numerals or other indications 5 can be arranged so as to be easily readable with slides of comparatively small dimensions.

The novelty resides in the fact that pins or the like engage with the slots of the tongues which prevent the tongues from being withdrawn completely from the guide sleeve.

tongues directly following one another are directed' towards difierent ends of the sleeve so that successive tongues can only be withdrawn from difierent sides of the sleeve. In this manner there is obviated the liability when withdrawing one tongue of withdrawing at the same time the adjacent tongue as the tongues are held in the sleeve by friction so that they do not lose accidentally the position which they have once assumed. At each end of the sleeve a notch is provided for each tongue adapted to be withdrawn at the corresponding end, whilst each tongue is provided with notches and also a handpiece, which projects into the notch of the sleeve.

Each tongue may also be engaged by itself in a notch of the sleeve.

In the drawings are illustrated diagrammatically a few examples of construction of the subject of the invention.

J Fig. 1 is a view of the group table slide.

Figs. 2 and 3 show cross and longitudinal sections.

i Fig. 5 shows a view of a further modification.

The slots of two The table slide is provided with a sleeve-like guide I in which

openings

2, 3, 4 are provided. The openings 3 and l are provided near the two ends of the guide I. The openings 2 may be provided at suitable points of the slide but they are preferably arranged in line with the

openings

3 or 4, as in this manner the possibility of reading the various inscriptions is facilitated, as the view can remain fixed on a definite point. In the guide I tongues 5 are so arranged that successive tongues can be withdrawn towards difierent ends. Each tongue has openings 1 near its ends which correspond in size and position with the

openings

2, 3, 4 so that the openings of all the tongues and the sleeve-like guide register with one another when all the slide tongues are pushed fully into the guide I. At the ends of the guide and tongues are formed recesses or notches 9 which correspond with one another. At separate points of the difierent slide tongues uninterrupted points 8 remain at which the corresponding tongues can be gripped separately and withdrawn. The points in question are located at different ends according to whether the corresponding tongue is to be withdrawn at one end or the other.

In order to prevent the tongues 5 from being withdrawn completely suitable stops are provided which in the examples of construction consist of elongated slots l2 formed in the tongues and of clamps or screw pins l5 passing through the guide and all the slots l2 of the tongues. The withdrawability of the separate tongues towards one end and other tongues towards the other end is facilitated by the provision of handpieces 8 on the tongues and it is also possible, if desired, to withdraw two tongues simultaneously towards both ends so as to enable indications on difierent tongues to be read through the

openings

3 and 4 and compared with one another.

The openings 2 are for example adapted to render visible guide numbers on the tongues, by means of which the setting of the tongues in the guide can be eflected. The remaining openings 3 and l expose the indications to be obtained. When withdrawing any one of the tongues of the pile and setting this to the guide number these indications can easily be read through the

openings

2 and 3 or t and the openings l of the tongues located in the position of rest above this tongue. All the tongues form a continuous table of which the indications are not located in one plane but stepwise above one another, so that the table has a handy form. In addition definite groups of indications when reading are separated from all remaining indications for which reason it is not necessary to search for them tediously but, without the possibility of any error being liable to occur they are immediately visible. When the table slide is to be constructed for one side only the openings on the back are omitted, but it indications are also to be provided on the back of the tongues, it will be understood that openings 2, I, 4 must be provided both in the front and in the back of the sleeve I. In Fig. 1 separate openings 2 are provided for the guide number or the like, while the

openings

3, 4 and I are interrupted by strengthening bars H which are provided with slots [2. It is however also possible to use transverse openings ll (Fig. 4) and the slots II are located on both longitudinal sides. The guide number or the like in this case appears at one end of the openings 3 and 4 (Fig. 5).

The example construction in Figs. 1 to 3 is constructed as a wage calculating slide. When withdrawing one tongue 8 the hour number of the working time appears in the opening 2, while in the

openings

3 or 4 there can be read the total amount corresponding with the particular wage which is obtained by the working time multiplied by the wage per hour noted adjacent the opening. Laterally oi the

openings

3 and 4 there may also be noted the wage for fractions of hours, which it necessary must be added to the total amount.

The example of construction in Fig. serves to determine the interests oi fixed interest bond papers at various rates of exchange and diirerent periods of time. The guide number indicated at the upper edge of the table, preferably printed in another colour indicates the rate of exchange oi. the bond paper whilst the interest is indicated at the gripping surfaces 01' the various tongues. In the openings I or 4 there appear laterally of the remarks on the sleeve regarding the years still remaining 0! the paper indications regarding the interests, 1. e. the average of interest amounts and gain on exchange on release. When using this table slide the tongue bearing the interest of the paper on the gripping point is withdrawn to the corresponding side until the rate of exchange has been set at the upper end of the opening. The interest is then read in the opening adjacent the number or years 0! the period still to run indicated on the sleeve. This slide is mainly of advantage for banks by reason oi the saving in time.

From these figures it will be seen that in a comparatively small space an extremely large number of indications or numbers can be provided so that the slide enables the calculations in question to be made within a very wide range whilst being of small dimensions.

In the form of construction in Fig. 4 the slide forms a notice table which enables entries of every type to be found easily. In the construction as telephone slide it enables the entries oi addresses and numbers of telephone subscribers, which can be entered in lead pencil to be again found immediately by moving the slide tongues which are provided at the gripping points with the corresponding letter of the alphabet. When the note is no longer required it can be erased easily, whilst indications which are always required may be printed. This form of construction may also be used as an exchange record and for many other purposes having entries changing according to a table.

The slide may be made 01 metal, celluloid, or any suitable material, paper or the like and adapted in shape to the purpose in view.

What I claim is:

A group table slide comprising a sleeve-like guide having a plurality oi openings therein and a plurality of superposed tongues in said guide each having a plurality of openings therein, said openings being oi such size and so arranged that when all the tongues are arranged in the guide corresponding openings in the guide and tongues are in registry, each of said tongues being provided with a longitudinal slot, said slot in the successive tongues extending toward opposite ends of said tongues, pins in the guide one ad- Jacent each end thereof, said pins passing through the slots of alternate tongues, said tongues being in mutual contact and the outermost tongues being in contact with the guide and means on the ends of said pins and engaging the outer face of said guide for pressing said guide and tongues together so that all the tongues are held by friction against casual movement, said tongues being adapted to be moved successively from opposite ends of the guide.
