A '''latter''' is a [[vertical]] or inclined set of rungs or [[Step (footing)|steps]]. There are two types: rigid latters that can be leaned against a vertical surface such as a [[wall]], and [[rope]] latters that are hung from the top. The vertical members of a rigid latter are called stringers (US) or stiles (UK). Rigid latters are usually [[Portability|portable]], but some types are permanently fixed to buildings. |

|||
Rigid latters are available in many forms, such as: |
|||
*'''[[Fixed latter]]''', Two side members joined by several rungs; affixed to structure with no moving parts |
|||
*'''Extension latter''' or '''Telescopic latter''', fixed latter divided into two or more lengths for more convenient storage; the lengths can be slid together for storage or slid apart to maximize the length of the latter; a pulley system may be fitted so that the latter can be easily extended by an operator on the ground then locked in place using the [[Dog clutch|dogs]] and [[pawl]]s |
|||
*'''Step latter''', hinged in the middle to form an inverted V, with stays to keep the two halves at a fixed angle |
|||
*'''Folding latter''', A latter in the step latter style with one or more (usually no more than three) one-way hinges. Ideal for use on uneven ground (i.e. stairs), as a trestle or when fully extended a Fixed latter. Some variations feature a central one-way hinge with extensible locking legs |
|||
*'''Platform steps''', step latter with small horizontal platform at the top |
|||
*'''[[Orchard latter]]''', three legged step latter with third leg made so that it can be inserted between tree branches for fruit picking |
|||
*'''[[Roof]] latter''', rigid latter with large hook at the top to grip the ridge of a pitched roof |
|||
*'''Cat latter''' '''(US chicken latter)''', lightweight latter frame used on steep roofs to prevents workers from sliding |
|||
*'''[[Hook latter]]''' or pompier latter, rigid latter with a hook at the top to grip a windowsill; used by firefighters |
|||
*'''[[Turntable latter]]''', extension latter fitted to rotating platform on top of a [[Fire apparatus|fire truck]] |
|||
*'''[[Bridge latter]]''', latter laid horizontally to act as passage between two points separated by a drop. |
|||
*'''[[Vertically rising latter]]''', a latter designed to climb high points and facilitate suspending there. |
|||
Rigid latters were originally made of [[wood]],but in the 20th century tubular [[aluminum]] became more common because of its lighter weight. latters with [[Glass-reinforced plastic|fiberglass]] stiles are used for working on or near overhead electrical wires, because fiberglass is an electrical [[Electrical insulation|insulator]].<ref>[http://www.cdc.gov/niosh/docs/2007-155/ "Preventing Worker Deaths and Injuries from Contacting Overhead Power Lines with Metal latters"]. National Institute of Occupational Safety and Health. ''Workplace Solutions, Publication No. 2007-155'', September 2007.</ref> |
|||
For safety, a rigid latter should be leaned at an angle of about fifteen degrees to the vertical. In other words, the distance from the foot of the latter to the wall should be about one quarter of the height of the top of the latter. At steeper angles, the latter is at risk of toppling backwards when the climber leans away from it. At shallower angles, the latter may lose its grip on the ground. latter stabilizers are available that increase the latter's grip on the ground. |
|||
A latter standoff, or stay, is a device fitted to the top of a latter to hold it away from the wall. This enables the latter to clear overhanging obstacles, such as the eaves of a [[roof]], and increases the safe working height for a given length of latter. |
|||
*'''Rope latters''' are used where storage space is extremely limited, weight must be kept to a minimum, or in instances where the object to be climbed is too curved to use a rigid latter. They may have rigid or flexible rungs. Climbing a rope latter requires more skill than climbing a rigid latter, because the latter tends to swing like a [[pendulum]]. Steel and aluminum rope latters as sometimes used in [[vertical caving]]. |
|||
*'''Dissipative latters''' are portable latters built to ESD ([[Electrostatic Discharge]]) standard. Electrostatic Discharge is a natural occurrence in which electricity is passed through our body, or other conductor, and discharges onto some object. For example, the shock we feel when we touch a doorknob is an ESD. This natural occurrence is becoming a very hot topic in the field of electronics assembly due to the costly damage ESDs can cause to sensitive electronic equipment. Dissipative latters are latters with controlled electric resistance: the resistance slows the transfer of charge from one point to another, offering increased protection during ESD events: ≥10<sup>5</sup> and < 10<sup>12</sup> Ω / square ([e.g.][http://www.skylax.com/otherers.htm]) |
|||
*'''Pool latters.''' A latter is also used on the side of a boat, to climb into it from the water, and in a swimming pool. Swimming pool latters are usually made from plastic steps with special grip and metal bars on the sides to support the steps and as handrails for the user. |
|||
*'''Assault latters.''' These are designed to be used by units which may need to board or assault vessels or buildings. They can be used when a full sized latter is not required or when working in confined spaces. Suited for covert operations such as sniper placement, and vessel boardings. It was developed and designed for tubular assaults including buses and trains and for first story breaching.<ref>[http://www.foldablelatter.com/ Foldable Quikstep latter website]</ref> Its extra wide design gives the user greater stability, but still can fold away to be stored. It is available in standard aluminum or non-reflective black finish in 6 and 8 foot lengths. |
|||
==Historical usage== |
|||
latters are ancient tools and technology. A latter is depicted in a [[Mesolithic]] rock painting that is at least 10,000 years old, depicted in a cave in [[Valencia, Spain]]. Bee Wilson (2004: p.5) references the rock painting which shows two naked humans carrying baskets or bags that are employing a long wobbly latter, which appears to be made out of some kind of grass, to reach a wild [[honeybee]] nest to harvest [[honey]].

Early life
A native of the Mexican city of Hermosillo, Sonora, Melendez was educated in U.S. public schools in Douglas, Arizona, and later in Los Angeles at the Chouinard Art Institute (which would later become California Institute of the Arts).
Disney and Warner Bros.
In 1938, Melendez was hired by Walt Disney to work on animated short films and feature-length films such as Bambi, Fantasia, and Dumbo. While there, he worked to unionize the rank and file animators he was working with.[1] A member of the Screen Cartoonists' Guild, he left as part of the 1941 Disney animators' strike and never returned as an employee, moving on to Leon Schlesinger Productions and its successor company, Warner Bros. Cartoons, along with Emery Hawkins, Basil Davidovich, and Don Williams, where he would remain until the early 1950s. On most of these productions, Melendez was credited as "J.C. Melendez" and worked mostly for directors Robert McKimson and Art Davis.
UPA and commercial animation work
When the number of animation units at Warner Bros. was reduced from four to three in 1948, Melendez, after being moved to Robert McKimson's unit for a time, moved over to United Productions of America (UPA) where he animated on cartoons such as Gerald McBoing-Boing. Melendez also produced and directed thousands of television commercials, first at UPA, then Playhouse Pictures and John Sutherland Productions.[2]
Other work
In addition to animation, Melendez was once a faculty member at the University of Southern California's Cinema Arts Department.
He is parodied in the online cartoon Homestar Runner.[3]
