RULING MAo'riIN'E.
Application fiIed'March 6, 1923. Serial No. 623,187;
This invention relates to improvements in ruling machines, and more especially adjusting devices for drafting board rulers.
The principal object of the invention is to accurately and gradually adjust the angle of inclination of a ruler.
Another object is to adjust, without detachment, a ruler carried by an endless belt attached to a drafting board.
In order to obtain these objects in accordance with features of the invention, one end of a ruler is secured to a. traveling belt by means of a screw propelled device whereby the effective point of such attachment may be given a refined adjustment without detaching the ruler from the belt, thus swinging the ruler around its other point of attachment as a pivot until a desired angle of inclination is obtained.
These and other. features not specifically mentioned will be apparent from the following description and the accompanying. drawings in which Fig. 1 shows a plan view of a drafting 7 board equipped with a ruler embodying this invention;
F 1g. 2 shows an end view of the drafting board showing the ad usting device associated with the ruler andv the. endless belt,
' Fig. 3 shows-an enlarged end view of a portion of the drafting board and the adj usting device associated withthe belt and the ruler, and
Fig. 4 shows an end view of the device and a portion of the drafting board.
Referring to the drawings,.l represents a drafting board'of'the usual type, at two corners of which are supported pairs of horizontally operating pulleys 2-2 and at the other corners of which individual vertically operating pulleys 33 are supported. An endless belt, which may take the form of a cord 4 passes around these pulleys and encompasses the three sides of the drafting board. A ruler 8, of any suitable type, ex-
tends vacross the drafting board and is attached at a point near its right-hand end to the belt 4 by any suitable means, which may take the form of a clamping arrangement for clamping the belt and securing it to the rulertlirough a suitable screw and washer arrangement. This means is not described in detail, since it may take any suitable form. The other end of the ruler 8 is a-ttachedto a horizontal plate 10 by means of a screw 11 extending through a washer 12 and engaging a tapped hole in the plate '10. An upright 14 is provided with athreaded horizontal hole extending therethrough and another horizontal opening at its lower portion. Through the threaded opening a thumb screw 16 extends and engages a clamping member 17. The jaws of the clamping member 17 engage the belt 1 and are secured thereto by the action of the screw 18. Attached to the lower portion of the clamping member 17 is a rod or guiding member 19 which extends through the lower horizontal opening of the upright 14 for directing the movement of the clamping lhelgllbfli 17 when the thumb screw 16 is actuate I When it is desired to change the angle of inclination of the ruler, the thumb screw 16 is actuated to move the left-hand end of the ruler either toward or away from the operator, thus swinging the ruler around the point of'attachment at its right-hand end as a pivot. In this manner a very close and accurate adjustment of the angle may be secured without the necessity of detaching either end of the ruler from the traveling belt or cord. This arrangement is of great importance when a drawing which has been partially completed on one drafting board is transfered to another drafting board the ruler of which may not have the same ad- 1. In a ruling machine, a belt, a member carried thereby, a carriage, a ruler attached thereto, adjustable means interconnecting the carriage and the member, and means carried by the carriage for guiding the movements of the member and the carriage during the adjustment of the interconnecting means.
2. In a ruling machine, a belt, a carriage, a ruler attached to the carriage, a post on the carriage, a'screw threaded through the post, a clamping member carried by the screw for engaging the belt, and a member attached to the clampmgmembe'r and passing through an opening in the post for guiding the motion of the carriage in response to the actuation of the screw.
In a ruling machine, a belt, a member secured thereto, a carriage, a ruler attached thereto, and a screw connected to the member and threadedly engaging the carriage to cause a relative movement between the member and the carriage in a direction substantially parallel with the longitudinal axis of the screw.
4t. In a ruling machine, a continuous belt,
a member secured thereto, a ruler, means for securing one end thereof to the belt, a carriage secured to the other end of the ruler, and a screw rotatably attached to the member and threadedly engaging the carriage for causing a relative movement between the carriage and the member, thereby turning the ruler around a pivot formed by the first mentioned means.
In Witness whereof, I hereunto subscribe my name this 22nd day of Feb. A. D.. 1923.
HENRY MARTIN OTTO.
